SUMMARY OF THE INVENTION

PROBLEMS TO BE SOLVED BY THE INVENTION

[0005] Here, for the mounting member as described in Patent Document 1, in order to set the pressing load for pressing the electronic component against the heat sink to a predetermined pressing load, the shorter the length of the pressing side portion, the stricter the tolerance setting needs to be. This may hinder cost reduction and is undesirable. On the other hand, for the mounting member, the longer the length of the pressing side portion, the higher the material cost, which hinders cost reduction, and also hinders downsizing.

[0006] The present disclosure has been made in consideration of such circumstances, and an object thereof is to provide a mounting member that can set the pressing load for pressing an electronic component against a mounted member to an appropriate pressing load while suppressing an increase in manufacturing cost.

MEANS FOR SOLVING THE PROBLEMS

[0007] One aspect of the present invention is a mounting member for attaching an electronic component to a member to be attached, comprising a pressing member having a first end perpendicular to a predetermined first direction, in contact with the electronic component, and pressing the electronic component against the member to be attached, and a second end facing the first end in the first direction, wherein the pressing member has a first gap formed therein that extends from one of two ends of the pressing member that are different from the first end and the second end, so as to intersect with the first direction.

[0008] Furthermore, one aspect of the present invention is a mounting member comprising a first mounting member and a second mounting member, wherein at least one of the first mounting member and the second mounting member is a pressing member having a first end perpendicular to a predetermined first direction, in contact with the electronic component, and pressing the electronic component against the mounting member, and a second end facing the first end in the first direction, wherein the pressing member has a first gap formed therein that extends from one of two ends of the pressing member that are different from the first end and the second end so as to intersect with the first direction. [Effects of the Invention]

[0009] According to the present invention, it is possible to set the pressing load applied to the mounting member to an appropriate pressing load while suppressing an increase in manufacturing costs. [Brief explanation of the drawing]

[0011] <Embodiment> Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] <Outline of Mounting Member> First, an outline of the mounting member according to the present embodiment will be described.

[0013] The mounting member according to the embodiment is a mounting member for mounting an electronic component to a member to be mounted. The mounting member according to the embodiment includes a pressing member. The pressing member has a first end portion and a second end portion. The first end portion is an end portion that is orthogonal to a predetermined first direction, comes into contact with the electronic component, and presses the electronic component against the member to be mounted. The second end portion is an end portion that faces the first end portion in the first direction. The pressing member is formed with a first void extending so as to intersect the first direction from one of two end portions different from the first end portion and the second end portion among the end portions of the pressing member.

[0014] Accordingly, the mounting member according to the embodiment can make the pressing load for pressing the electronic component against the member to be mounted an appropriate pressing load while suppressing an increase in manufacturing cost.

[0015] Hereinafter, the configuration of the mounting member according to the embodiment will be described in detail.

[0016] <Configuration of Mounting Member> First, the configuration of the mounting member 1 according to the embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing a first example of the configuration of the mounting member 1 according to the embodiment.

[0017] Here, the three-dimensional coordinate system TC is a three-dimensional orthogonal coordinate system that indicates directions in the diagram in which the three-dimensional coordinate system TC is depicted. In the following, for convenience of explanation, the X-axis in the three-dimensional coordinate system TC will be referred to simply as the X-axis for description. Also, in the following, for convenience of explanation, the Y-axis in the three-dimensional coordinate system TC will be referred to simply as the Y-axis for description. Also, in the following, for convenience of explanation, the Z-axis in the three-dimensional coordinate system TC will be referred to simply as the Z-axis for description. Also, in the following, for convenience of explanation, the positive direction of the Z-axis will be referred to as upward or the upward direction, and the negative direction of the Z-axis will be referred to as downward or the downward direction for description.

[0018] The mounting member 1 is a member for mounting an electronic component to a mounted member. Here, the mounted member may be any member as long as it is a member to which the electronic component is mounted, and examples thereof include a heat sink, a substrate, and the like. In the following, as an example, a case where the mounting member 1 mounts an electronic component EP to a mounted member HS as shown in FIG. 1 will be described.

[0019] The mounted member HS is, for example, a rectangular heat sink. Note that the mounted member HS may be a substrate, an electronic component other than the electronic component EP, a housing (not shown), or the like, instead of the heat sink.

[0020] The electronic component EP is, for example, a transistor. Note that the electronic component EP may be another electronic component instead of a transistor.

[0021] The mounting member 1 is fixed to the mounted member HS by a fixing member FX. In other words, the mounting member 1 is attached to the mounted member HS by the fixing member FX. In the example shown in FIG. 1, the fixing member FX is a screw, but may be another member capable of fixing the mounting member 1 to the mounted member HS.

[0022] The mounting member 1 includes a pressing member 11, a holding member 12, a fixed member 13, and a connecting member 14. Note that the mounting member 1 may have a configuration that does not include at least one of the holding member 12, the fixed member 13, and the connecting member 14.

[0023] The pressing member 11 is a member having a first end E1 and a second end E2. The first end E1 is the end of the pressing member 11 that is perpendicular to a predetermined first direction, contacts the electronic component EP, and presses the electronic component EP against the mounting member HS. The second end E2 is the end of the pressing member 11 that faces the first end E1 in the first direction. In the example shown in Figure 1, the pressing member 11 is a member with a substantially rectangular flat plate shape. Therefore, in this example, the first end E1 and the second end E2 are substantially parallel, except for deviations due to manufacturing errors, etc. Below, as an example, we will describe the case where the first end E1 and the second end E2 are parallel to the X-axis, as shown in Figure 1. Below, as an example, we will describe the case where the first direction is the direction perpendicular to the first end E1, and is the direction along the upper surface of the pressing member 11 from the first end E1 to the second end E2. In this case, the first direction is parallel to the Y-axis. Furthermore, as an example, the case in which the direction perpendicular to the upper surface of the pressing member 11 is parallel to the Z-axis will be described below, as shown in Figure 1. Note that the first end E1 may be curved. In this case, the direction perpendicular to the first end E1 may be, for example, perpendicular to a hypothetical line segment connecting both ends of the first end E1, or perpendicular to another hypothetical line segment depending on the shape of the first end E1. Also, the second end E2 may be non-parallel to the first end E1 and may be curved. Furthermore, the pressing member 11 may be a member with a shape other than a substantially flat plate, as long as it is elastically deformable and capable of pressing the electronic component EP against the mounting member HS by elastic force.

[0024] The gripping member 12 is a substantially rectangular flat plate-shaped member that protrudes from the first end E1 in a predetermined second direction, and is made by bending the pressing member 11 to prevent the electronic component from being pressed by the sharp first end E1. Therefore, the aforementioned first end E1 is the boundary portion between the gripping member 12 and the pressing member 11. Here, the second direction may be any direction that moves away from the mounting member HS among the directions that intersect with the upper surface of the pressing member 11 when the mounting member 1 is attached to the mounting member HS. In the example shown in Figure 1, the second direction is the direction that moves away from the mounting member HS among the directions that are perpendicular to the upper surface of the pressing member 11 in this case. For example, the user places the electronic component EP at a predetermined position on the mounting member HS and attaches the electronic component EP to the mounting member HS using the mounting member 1 so that the placed electronic component EP is difficult to move relative to the mounting member HS. Then, when the mounting member 1 attaches the electronic component EP to the mounting member HS, the pressing member 11 of the mounting member 1 elastically deforms and presses the electronic component EP against the mounting member HS. In other words, the mounting member 1 can attach the electronic component EP to the mounting member HS by pressing it against the mounting member HS with the elastic force of the pressing member 11 between the pressing member 11 and the mounting member HS. Note that the gripping member 12 may have a shape other than the substantially rectangular flat plate shape.

[0025] The fixed member 13 is a member that is fixed to the mounting member HS by the fixing member FX. In the example shown in Figure 1, the fixed member 13 is a substantially rectangular flat plate shaped member, with an opening formed as a screw hole near the center through which the fixing member FX is inserted. In this example, the fixed member 13 is fixed to the mounting member HS by the fixing member FX inserted through the opening. Note that the fixed member 13 may have any shape other than a substantially rectangular flat plate shape, as long as it can be fixed to the mounting member HS by the fixing member FX.

[0026] The connecting member 14 is a member that connects the fixed member 13 and the pressing member 11. Therefore, the aforementioned second end E2 is the boundary portion between the connecting member 14 and the pressing member 11. In the example shown in Figure 1, the connecting member 14 is a substantially rectangular flat plate shaped member that extends in a predetermined third direction from the boundary portion between the fixed member 13 and the connecting member 14. Here, the third direction is, for example, a direction away from the fixed member HS that is perpendicular to the upper surface of the fixed member HS. This allows the mounting member 1 to have the second end E2 higher than the first end E1 with respect to its upper surface, and as a result, it is possible to easily sandwich the electronic component EP between the pressing member 11 and the fixed member HS while maintaining the magnitude of the pressing load by the pressing member 11. In this case, the virtual plane including the substantially rectangular flat plate shaped pressing member 11 intersects with the virtual plane including the substantially rectangular flat plate shaped fixed member 13. The third direction may be any other direction that intersects with the upper surface of the fixed member HS. Furthermore, the third direction may be substantially parallel to the upper surface. In this case, the virtual plane containing the substantially rectangular flat pressing member 11 is substantially parallel to the virtual plane containing the substantially rectangular flat fixed member 13, excluding distortions due to manufacturing errors, etc.

[0027] In this configuration of mounting member 1, the pressing load F applied by the pressing member 11 to press the electronic component EP against the mounting member HS is related to the amount of deflection X of the pressing member 11 by the following equation (1).

[0028] X = (F × L) 3 ) / (3×E×I) ···(1)

[0029] Here, in equation (1) above, L represents the length of the shortest path connecting the first end E1 and the second end E2 along the upper surface of the pressing member 11 (i.e., the surface connecting the first end E1 and the second end E2). For example, if no gap is formed in the pressing member 11, L is equal to the length of a hypothetical line segment connecting the first end E1 and the second end E2 in the first direction. Here, the gap is, for example, a notch or an opening, but is not limited to these. Also, in equation (1), E is the Young's modulus of the pressing member 11, and for example, if the pressing member 11 is made of SUS304CSP, it is 186000 N / mm 2 In equation (1), I is the second moment of area of ​​the pressing member 11. For example, if the shape of the pressing member 11 is a rectangular flat plate, I is the value obtained by multiplying the width of the pressing member 11 in the direction perpendicular to the first direction by the cube of the thickness of the pressing member 11 and dividing the result by 12. For the sake of explanation, the length of the line segment in question will be referred to as the comparison length below.

[0030] The tolerance of the deflection amount X calculated by the above formula (1) becomes smaller as L decreases. A smaller tolerance for the deflection amount X means an increase in the manufacturing cost of the mounting member 1, which is undesirable. On the other hand, increasing the length of the pressing member 11 in the first direction can increase the tolerance of the deflection amount X. However, in this case as well, the material cost of the pressing member 11 increases, leading to an increase in the manufacturing cost of the mounting member 1. Furthermore, if no gap is formed in the pressing member 11, L cannot be made longer than the aforementioned comparison length unless the length of the pressing member 11 in the first direction is increased.

[0031] Therefore, the mounting member 1 has a gap formed in the pressing member 11 such that the length L is longer than the length of the comparison target. This allows the tolerance of the deflection amount X of the mounting member 1 to be larger compared to when no gap is formed in the pressing member 11. As a result, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs.

[0032] Figure 2 is a top view of the pressing member 11 shown in Figure 1. For the sake of explanation, in the following description, a hypothetical axis passing through the center of gravity of the pressing member 11 and parallel to the first direction will be referred to as the central axis of the pressing member 11. L1 shown in Figure 2 is an example of the comparison length mentioned above. Also, as shown in Figures 1 and 2, the pressing member 11 has three gaps that intersect with the first direction. For the sake of explanation, in the following description, these three gaps will be referred to as gap C1, gap C2, and gap C3.

[0033] The gap C1 is a gap that extends from one of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, so as to intersect with the first direction. In the example shown in Figures 1 and 2, the gap C1 is a notch that extends from the end of the pressing member 11 on the positive X-axis side so as to be perpendicular to the first direction. More specifically, in this example, the gap C1 is an L-shaped notch that extends from that end in the negative X-axis direction, and then extends in the positive Y-axis direction. The gap C1 may also be a notch that extends from that end in a direction oblique to the Y-axis, and then extends in the positive Y-axis direction. Alternatively, the gap C1 may be a notch that extends from that end in a direction perpendicular to the Y-axis, and then extends in a direction oblique to the X-axis. Furthermore, the gap C1 may be a notch that extends from the end in a direction oblique to the Y-axis, and then extends in a direction oblique to the X-axis.

[0034] The gap C2 is a gap that extends from the other of two ends of the pressing member 11 that are different from the first end E1 and the second end E2, so as to intersect with the first direction. In the examples shown in Figures 1 and 2, the gap C2 is a notch that extends from the end of the pressing member 11 on the negative side of the X-axis so as to be perpendicular to the first direction. More specifically, the gap C2 is an L-shaped notch that extends from that end toward the positive direction of the X-axis, and then extends toward the positive direction of the Y-axis. The gap C2 may also be a notch that extends from that end toward a direction oblique to the Y-axis, and then extends toward the positive direction of the Y-axis. Alternatively, the gap C2 may be a notch that extends from that end toward a direction perpendicular to the Y-axis, and then extends toward a direction oblique to the X-axis. Furthermore, the gap C2 may be a notch that extends from the end in a direction oblique to the Y-axis, and then extends in a direction oblique to the X-axis.

[0035] The gap C3 is a gap that intersects the first direction between two ends of the pressing member 11 that are different from the first end E1 and the second end E2. In the examples shown in Figures 1 and 2, the gap C3 is an opening formed in the pressing member 11 between these two ends so as to intersect the first direction. More specifically, the gap C3 is a U-shaped opening formed between these two ends, closer to the second end E2 than gaps C1 and C2, and enclosing a portion of each of gaps C1 and C2.

[0036] In the examples shown in Figures 1 and 2, each of the gaps C1, C2, and C3 is formed such that the shape of the pressing member 11 is symmetrical with respect to the central axis of the pressing member 11. In this case, a hypothetical straight line connecting the first end E1 and the second end E2 along the surface of the pressing member 11 intersects at least one of the gaps C1, C2, and C3. The dashed line LN shown in Figure 2 is an example of such a hypothetical straight line. As shown in Figure 2, the dashed line LN intersects each of the gaps C1 and C3 once. The same applies to any other hypothetical straight line connecting the first end E1 and the second end E2 along the surface of the pressing member 11. In this case, the shortest path connecting the first end E1 and the second end E2 along the upper surface of the pressing member 11 will include one or more partial paths that are not parallel to the first direction between the first end E1 and the second end E2, as shown in Figure 2, due to the presence of a gap formed in the pressing member 11. Specifically, in the example shown in Figure 2, the shortest path is the path indicated by the dotted line shown in Figure 2, i.e., the path that includes partial paths CP1 to CP5. Partial path CP1 is the path that goes parallel to the first direction from position P1 on the first end E1 to position P2, which is closer to the second end E2 than the first end E1. Partial path CP2 is the path that goes parallel to the X-axis from position P2 to position P3, which is located on the negative side of the X-axis than position P2. Partial path CP3 is the path that goes from position P3 to position P4, which is closer to the first end E1 than position P3 and also on the negative side of the X-axis than position P3. Partial path CP4 is a path that runs parallel to the X-axis from position P4 to position P5, which is located on the negative side of the X-axis than position P4. Partial path CP5 is a path that runs parallel to the first direction from position P5 to position P6, which is located on the second end E2. Thus, in this example, the shortest path includes two partial paths that are not parallel to the first direction between the first end E1 and the second end E2 due to the presence of gaps C1, C2, and C3 formed in the pressing member 11. As a result, the length L of the shortest path is the same as the length L2 of the path shown by the dotted line in Figure 2. And, as shown in Figure 2, L2 > L1.As a result, in the pressing member 11 shown in Figure 2, the tolerance of the deflection amount X is larger than when no gap is formed in the pressing member 11. Therefore, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs.

[0037] Furthermore, at least one of the gaps C1 and C2 may not have a portion extending in the positive direction of the Y-axis. However, if at least one of the gaps C1 and C2 of the mounting member 1 has a portion extending in the positive direction of the Y-axis, the pressing member 11 becomes more flexible, and the crossover of the deflection amount X can be increased more reliably.

[0038] Furthermore, the pressing member 11 may be configured to have a gap, as shown in Figure 3. Figure 3 is a perspective view showing a second example of the configuration of the mounting member 1. Note that in Figure 3, the mounting member HS and the fixing member FX are omitted to avoid making the diagram too complex. In the example shown in Figure 3, the pressing member 11 has a gap C4 and a gap C5.

[0039] The gap C4 is a gap that extends from one of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, so as to intersect with the first direction. In the example shown in Figure 3, the gap C4 is a notch that extends from the end of the pressing member 11 on the positive X-axis side so as to be perpendicular to the first direction. More specifically, the gap C4 is a notch that extends from that end toward the negative X-axis direction.

[0040] The gap C5 is a gap that extends from the other of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, so as to intersect with the first direction. In the example shown in Figure 3, the gap C5 is a notch that extends from the end of the pressing member 11 on the negative side of the X-axis so as to be perpendicular to the first direction. More specifically, the gap C5 is a notch that extends from that end toward the positive direction of the X-axis.

[0041] Furthermore, the gap C5 is a notch closer to the first end E1 than the gap C4. And, when viewing the pressing member 11 in the first direction, a portion of the gap C5 overlaps with a portion of the gap C4. For this reason, in the example shown in Figure 3, the imaginary straight line connecting the first end E1 and the second end E2 along the surface of the pressing member 11 intersects with either or both of the gaps C4 and C5. As a result, in this example, the shortest path CP6 along the upper surface of the pressing member 11 that connects the first end E1 and the second end E2 in the shortest time includes one or more non-parallel partial paths between the first end E1 and the second end E2, as shown in Figure 3, due to the presence of gaps C4 and C5 formed in the pressing member 11. In other words, in the pressing member 11 shown in Figure 3, the tolerance of the deflection amount X is larger compared to when no gaps are formed in the pressing member 11. Therefore, even if the configuration of the pressing member 11 is as shown in Figure 3, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs.

[0042] Furthermore, the pressing member 11 may be configured to have gaps, as shown in Figure 4. Figure 4 is a perspective view showing a third example of the configuration of the mounting member 1. Note that in Figure 4, the mounting member HS and the fixing member FX are omitted to avoid making the diagram too complex. In the example shown in Figure 4, gaps C6, C7, and C8 are formed in the pressing member 11.

[0043] The gap C6 is a gap that extends from one of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, so as to intersect with the first direction. In the example shown in Figure 4, the gap C6 is a notch that extends from the end of the pressing member 11 on the positive X-axis side so as to be perpendicular to the first direction. More specifically, the gap C6 is a notch that extends from that end in the negative X-axis direction to just before the central axis of the pressing member 11.

[0044] The gap C7 is a gap that extends from the other of two ends of the pressing member 11 that are different from the first end E1 and the second end E2, intersecting the first direction. In the example shown in Figure 4, the gap C7 is a notch that extends from the end of the pressing member 11 on the negative side of the X-axis, perpendicular to the first direction. More specifically, the gap C7 is a notch that extends from that end in the positive direction of the X-axis to just before the central axis of the pressing member 11.

[0045] The gap C8 is a notch having a portion extending from the first end E1 in a first direction. More specifically, the gap C8 is a notch that extends from the first end E1 along the central axis in a first direction to just before the second end E2, and then extends in the positive and negative directions of the X-axis, respectively.

[0046] In the example shown in Figure 4, each of the gaps C6, C7, and C8 is formed such that the shape of the pressing member 11 is symmetrical with respect to the central axis of the pressing member 11. Also, in this example, when viewing the pressing member 11 in the first direction, a portion of gap C8 overlaps with a portion of each of gaps C6 and C7. Therefore, in this example, a hypothetical straight line connecting the first end E1 and the second end E2 along the surface of the pressing member 11 intersects with at least one of gaps C6, C7, and C8. As a result, in this example, the shortest path CP7 connecting the first end E1 and the second end E2 along the upper surface of the pressing member 11 includes one or more non-parallel partial paths between the first end E1 and the second end E2, as shown in Figure 4, due to the presence of gaps C6, C7, and C8 formed in the pressing member 11. In other words, in the pressing member 11 shown in Figure 4, the tolerance of the deflection amount X is larger compared to the case where no gap is formed in the pressing member 11. Therefore, even if the configuration of the pressing member 11 is as shown in Figure 4, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs.

[0047] Furthermore, the pressing member 11 may be configured to have gaps, as shown in Figure 5. Figure 5 is a perspective view showing a fourth example of the configuration of the mounting member 1. Note that in Figure 5, the mounting member HS and the fixing member FX are omitted to avoid making the diagram too complex. In the example shown in Figure 5, the pressing member 11 has gaps C9, C10, and C11.

[0048] The gap C9 is a gap that extends from one of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, intersecting the first direction. In the example shown in Figure 5, the gap C9 is a notch formed at the end of the pressing member 11 that is on the positive X-axis side. More specifically, the gap C9 is a notch that extends from that end in the negative X-axis direction to just before the central axis of the pressing member 11.

[0049] The gap C10 is a gap that extends from the other of two ends of the pressing member 11 that are different from the first end E1 and the second end E2, intersecting the first direction. In the example shown in Figure 5, the gap C10 is a notch formed at the end of the pressing member 11 on the negative side of the X-axis. More specifically, the gap C10 is a notch that extends from that end in the positive direction of the X-axis to just before the central axis of the pressing member 11.

[0050] The gap C11 is a notch having a portion extending from the first end E1 in a first direction. More specifically, the gap C11 is a notch that extends from the first end E1 along the central axis in a first direction to just before the second end E2, extends from a position a predetermined first distance from the first end E1 along the central axis in a first direction in both the positive and negative directions of the X-axis, and further extends from a position a predetermined second distance from the first end E1 along the central axis in both the positive and negative directions of the X-axis. However, the second distance is longer than the first distance.

[0051] In the example shown in Figure 5, each of the gaps C9, C10, and C11 is formed such that the shape of the pressing member 11 is symmetrical with respect to the central axis of the pressing member 11. Also, in this example, when viewing the pressing member 11 in the first direction, a portion of gap C11 overlaps with a portion of each of gaps C9 and C10. Therefore, in this example, a hypothetical straight line connecting the first end E1 and the second end E2 along the surface of the pressing member 11 intersects with at least one of gaps C9, C10, and C11. As a result, in this example, the shortest path CP8 connecting the first end E1 and the second end E2 along the upper surface of the pressing member 11 includes one or more partial paths that are not parallel to the first direction between the first end E1 and the second end E2, as shown in Figure 5, due to the presence of gaps C9, C10, and C11 formed in the pressing member 11. In other words, in the pressing member 11 shown in Figure 5, the tolerance of the deflection amount X becomes larger compared to the case where no gaps are formed in the pressing member 11. Therefore, even if the configuration of the pressing member 11 is as shown in Figure 5, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs.

[0052] As described above, the tolerance of the deflection amount X can be characterized by L, and can be increased by increasing L. However, increasing the tolerance of the deflection amount X can also be achieved by simply narrowing the width of the pressing member 11 between the first end E1 and the second end E2, instead of increasing L. This is because when the width of the pressing member 11 between the first end E1 and the second end E2 is narrowed, the pressing member 11 becomes relatively more flexible. However, in this case, the relationship between the tolerance of the deflection amount X and the width of the pressing member 11 changes depending on the position where the width of the pressing member 11 is narrowed. Therefore, in order to increase the tolerance of the deflection amount X by simply narrowing the width of the pressing member 11 between the first end E1 and the second end E2, it is necessary to obtain this relationship through prior testing, simulation, etc.

[0053] Figure 6 is a perspective view showing a fifth example of the configuration of the mounting member 1. Note that in Figure 6, the mounting member HS and the fixing member FX are omitted to avoid clutter. In the example shown in Figure 6, a gap C12 is formed in the pressing member 11.

[0054] The gap C12 is a gap that extends from one of the two ends of the pressing member 11 that are different from the first end E1 and the second end E2, intersecting the first direction. In the example shown in Figure 6, the gap C12 is a notch that extends from the end of the pressing member 11 on the negative side of the X-axis, perpendicular to the first direction. More specifically, the gap C12 is a notch that extends from that end toward the positive direction of the X-axis. In this case, when the pressing member 11 is viewed toward the first direction, the gap C12 overlaps with a part of the first end E1. Therefore, in the example shown in Figure 6, the length of the shortest path connecting the first end E1 and the second end E2 along the upper surface of the pressing member 11 is the same as the comparison length mentioned above. However, in this case, there is a section between the first end E1 and the second end E2 in Figure 6 where the width in the direction perpendicular to the first direction is narrowed due to the formation of the gap C12. Specifically, the width W1 shown in Figure 6 is narrower than the width W2 shown in Figure 6. Therefore, even with the pressing member 11 shown in Figure 6, the tolerance of the deflection amount X is larger compared to the case where no gap is formed in the pressing member 11. Consequently, even if the configuration of the pressing member 11 is as shown in Figure 6, the mounting member 1 can achieve an appropriate pressing load for pressing the electronic component EP against the mounting member HS while suppressing an increase in manufacturing costs. Note that the width W1 is the width in the direction perpendicular to the first direction of the portion of the pressing member 11 that connects the portion of the pressing member 11 that is closer to the second end E2 than the gap C12 in the first direction and the portion of the pressing member 11 that is closer to the first end E1 than the gap C12 in the first direction. On the other hand, width W2 is the width of the portion of the pressing member 11 that is closer to the second end E2 than the gap C12 in the first direction, or the width of the portion of the pressing member 11 that is closer to the first end E1 than the gap C12 in the first direction, in a direction perpendicular to the first direction.

[0055] <Modified examples of embodiments> The following describes a modified example of the embodiment with reference to Figure 7. Figure 7 is a diagram showing an example of the configuration of the mounting member 2 according to a modified example of the embodiment. The mounting member 2 comprises two or more mounting members. At least one of these two or more mounting members is the mounting member 1 according to the embodiment. In the example shown in Figure 7, the mounting member 2 comprises two mounting members, a first mounting member 1A and a second mounting member 1B. Both of these mounting members are mounting member 1. Note that the mounting member 2 may also be configured to comprise three or more mounting members. In this case, at least one of the three or more mounting members is the mounting member 1 according to the embodiment.

[0056] More specifically, in mounting member 2, the fixed member 13 of the first mounting member 1A and the fixed member 13 of the second mounting member 1B are configured as a single, substantially rectangular flat plate-shaped member. Furthermore, in mounting member 2, the virtual plane including the pressing member 11 of the first mounting member 1A includes the virtual plane including the pressing member 11 of the second mounting member 1B. As a result, mounting member 2 can attach electronic component EP1 to the mounted member HS by the first mounting member 1A, and attach electronic component EP2 to the mounted member HS by the second mounting member 1B. Moreover, mounting member 2 can achieve an appropriate pressing load for pressing electronic components against the mounted member while suppressing an increase in manufacturing costs.

As a result, the mounting member can achieve an appropriate pressing load for pressing electronic components against the mounting member while suppressing an increase in manufacturing costs.
