DETAILED DESCRIPTION OF THE INVENTION

[0014] Each embodiment will be described below with reference to the drawings. In all drawings, the same or corresponding components are designated by the same reference numerals, and common descriptions will be omitted. It should be noted that in this disclosure, the drawings may relate to one or more embodiments. Furthermore, among the arrows shown in each block diagram, unidirectional arrows simply indicate the direction of flow of a certain signal (data), and do not exclude bidirectionality.

[0015] First Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. FIG. 1 is a schematic diagram of a mounting system 1 according to the present disclosure, and its main components are a substrate stage 2, a pressure block 3, a mounting head 4, a mounting head moving mechanism 5, a mechanical stopper 6, a mechanical stopper moving mechanism 7, a distance sensor 8, and a control means 9.

[0016] The substrate stage 2 is a base on which the mounting substrate M is placed, and the mounting substrate M is positioned along the XY plane. The pressure block 3 holds and heats the electronic element E. The mounting system 1 further includes a gripping means 10 , a heating means 11 and a pressure means 12 .

[0017] The gripping means 10 is installed below the pressure block 3 and grips the electronic element E in a state where the bumps B formed on the circuit surface face the mounting board M. The heating means 11 is disposed below the pressure block 3 and adjacent to the holding means 10 . The heating means 11 heats the electronic element E held by the holding means 10 . For example, the pressure applying means 12 may comprise a voice coil motor. The voice coil motor of the pressure means 12 applies pressure to the pressure block 3 in the direction of the arrow Z along the vertical direction. The voice coil motor of the pressure applying means 12 can apply pressure to the pressure applying block 3 in a direction toward the mounting substrate M (in the direction of arrow Z1), and can also apply pressure to the pressure applying block 3 in a direction away from the mounting substrate M (in the direction of arrow Z2) (described later).

[0018] The mounting head 4 supports the pressure block 3 via a linear guide 13 so that the pressure block 3 can be raised and lowered in the direction of the arrow Z toward the substrate stage 2 . The mounting head moving mechanism 5 has a fixed head 20 fixed to the mounting head 4, a screw shaft 21 threadedly engaged with the fixed head 20 and extending in the vertical direction, and a drive motor 22 for rotating the screw shaft 21. In the mounting head moving mechanism 5, the screw shaft 21 is rotated by the drive motor 22, whereby the mounting head 4 can be raised and lowered together with the fixed head 20 in the direction of the arrow Z.

[0019] The mechanical stopper 6 and the mechanical stopper moving mechanism 7 are provided on the upper surface of a horizontal step 4A that protrudes horizontally at the lower inner position of the mounting head 4. The mechanical stopper 6 is provided so as to be able to come into contact with the lower surface of a horizontal step portion 3A that protrudes horizontally from the upper portion of the pressure block 3, and stops the pressure block 3 from descending. The mechanical stopper moving mechanism 7 is installed between the mechanical stopper 6 and the horizontal step portion 4A of the mounting head 4. The mechanical stopper moving mechanism 7 functions as a lifting means capable of adjusting the height position of the mechanical stopper 6.

[0020] A distance sensor 8 is provided on the upper surface of the horizontal step 4A of the mounting head 4. The distance sensor 8 detects the height distance between the horizontal step portion 3A of the pressure block 3, as shown by the symbol h in Figure 2, thereby measuring the height distance between the pressure block 3 and the mounting head 4 and also measuring the amount of expansion of the pressure block 3 in the height direction due to heating. The control means 9 determines whether or not the height distance between the horizontal step portion 3A of the pressure block 3 detected by the distance sensor 8 is greater than a preset reference value (=H+H1). Thereafter, when the height distance (h) detected by the distance sensor 8 is greater than the reference value (=H+H1), the control means 9 causes the mechanical stopper moving mechanism 7 to adjust the height position of the mechanical stopper 6 (see Figures 3 and 4). The control means 9 also controls the driving of the mounting head moving mechanism 5 based on the height distance (h) detected by the distance sensor 8.

[0021] Here, "H", which is set as the reference value, is a value indicating the distance between the mechanical stopper 6 and the horizontal step portion 3A of the pressure block 3 when the mechanical stopper 6 comes into contact with the horizontal step portion 3A of the pressure block 3 before the pressure block 3 thermally expands (see Figure 2). Furthermore, "H1" set as a reference value is a value indicating the height of the bump B of the electronic element E, and represents the amount of bump crushing (see FIGS. 3 and 4). Then, under the condition that the pressure block 3 thermally expands due to heating and the height distance (h) detected by the distance sensor 8 becomes larger than the reference value (=H+H1), the control means 9 raises the mechanical stopper 6 by the length of expansion of the pressure block 3 (indicated by the symbol α in Figures 4 and 5) (to be described later).

[0022] Next, a method for controlling the amount of crushing of bumps when the bumps melt in the mounting system 1 of the embodiment will be described with reference to FIGS. The following processing is executed by the control means 9.

[0023] First, the height (h) of the pressure block 3 is measured by the distance sensor 8 in advance with the mechanical stopper 6 and the pressure block 3 in contact with each other, and the measured value is set as "H" (see FIG. 2).

[0024] Next, the electronic element E held by the holding means 10 and the mounting substrate M held by the substrate stage 2 are aligned in the in-plane directions (XY directions) on the substrate stage 2 (see FIG. 1). At this time, the alignment of the electronic element E and the mounting substrate M in the in-plane direction may be performed using image data captured by a camera. Thereafter, while a constant load is applied downward (in the direction of arrow Z1) to the pressure block 3 by the pressure means 12, the pressure block 3 is lowered together with the mounting head 4 by the mounting head moving mechanism 5 toward the substrate stage 2. This brings the bumps B of the electronic element E into contact with the electrodes of the mounting substrate M (see FIGS. 1 and 2).

[0025] Here, the voice coil motor of the pressure applying means 12 can apply a load in a direction (indicated by arrow Z2) that cancels out the weight of the pressure applying block 3, heating means 11, and holding means 10, thereby minimizing the load applied to the electronic element E (see Figure 2).

[0026] Furthermore, the mounting head moving mechanism 5 moves the pressure block 3 together with the mounting head 4 toward the substrate stage 2 in the direction of arrow Z1. However, since the bumps B of the electronic element E held by the pressure block 3 are in contact with the electrodes of the mounting substrate M, the electronic element E cannot move any further toward the substrate stage 2 side. At this time, the pressure block 3 moves away from the mechanical stopper 6, and when the detection value (h) of the distance sensor 8 reaches the reference value "H+H1", the movement of the mounting head 4 downward (in the direction of arrow Z1) is stopped (see Figures 3 and 4).

[0027] Here, the distance between the horizontal step portion 3A of the pressure block 3 and the mechanical stopper 6 is set to a preset bump crushing amount "H1." Whether or not the bumps B of the electronic element E come into contact with the electrodes of the mounting substrate M may be detected by a sensor such as a load cell. Then, the mounting head moving mechanism 5 may move the mounting head 4 toward the substrate stage 2 by the height of the bump crushing amount "H1" based on the detection result of a sensor such as a load cell.

[0028] Next, the electronic element E is heated by the heating means 11 . At this time, the pressure block 3, the heating means 11, and their peripheral members thermally expand due to the temperature rise, causing the horizontal step 3A of the pressure block 3 to move in the direction of arrow Z2 away from the horizontal step 4A of the mounting head 4.

[0029] The distance that the pressure block 3 moves at this time is measured by the distance sensor 8 . Thereafter, the mechanical stopper moving mechanism 7 raises the mechanical stopper 6 by the distance by which the detected height (h) by the distance sensor 8 exceeds the reference value "H+H1", i.e., the length (α) by which the pressure block 3 expands (see Figures 4 and 5).

[0030] The mechanical stopper moving mechanism 7 repeats this operation during heating, thereby maintaining the distance between the pressure block 3 and the mechanical stopper 6. The mechanical stopper moving mechanism 7 is set to rise only when the gap between the pressure block 3 and the mechanical stopper 6 widens, and not to operate when the gap between the pressure block 3 and the mechanical stopper 6 narrows.

[0031] Thereafter, the pressure block 3 moves in the direction of the arrow Z1 on the substrate stage 2 as the bumps B on the electronic element E liquefy when they reach their melting point and as a load is applied in the direction of the downward arrow Z1 by the voice coil motor of the pressure means 12. At this time, the distance sensor 8 detects the movement distance (negative value) of the position of the pressure block 3. However, at this time, the mechanical stopper 6 is set so that it can only move up and cannot move down, so its position does not move. Therefore, the pressure block 3 comes into contact with the mechanical stopper 6 and descends until the descending distance reaches the preset bump crushing amount "H1" (see FIGS. 4 and 5).

[0032] That is, the pressure block 3 starts from a state in which the bumps B of the electronic element E and the electrodes of the mounting substrate M are in contact with each other, and then crushes the bumps B on the electronic element E by a preset bump crushing amount H1. The melting of the bumps B on the electronic element E can be detected by checking whether the height (h) detected by the distance sensor 8 reaches "H" which is set as a reference value. In addition, the mounting head moving mechanism 5 can flexibly adjust the distance between the electronic element E and the mounting substrate M by appropriately adjusting the pressure block 3 to rise or fall together with the mounting head 4 while the bumps B are melted.

[0033] As described in detail above, in the mounting system 1 according to the present disclosure, even if the pressure block 3 thermally expands during the heating process of the electronic element E, it is possible to keep the amount of bump crushing (H1) constant when the bump melts, thereby stabilizing the mounting quality of the electronic element E.

[0034] Furthermore, in the mounting system 1 according to the present disclosure, the mechanical stopper 6 is controlled to be raised by the distance that exceeds the reference value "H+H1" when the detected height (h) by the distance sensor 8, i.e., the length (α) of the thermal expansion of the pressure block 3. As a result, in the mounting system 1 according to the present disclosure, the height position of the mechanical stopper 6 is adjusted by the mechanical stopper moving mechanism 7 only under specific conditions, which has the advantage of simplifying the control content compared to when the height position of the mechanical stopper is controlled at all times.

[0035] Second Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 6, the mounting system 101 includes a substrate stage 102, a pressure block 103, a mounting head 104, a mounting head moving mechanism 105, a mechanical stopper 106, a mechanical stopper moving mechanism 107, a distance sensor 108, and a control means 109.

[0036] A mounting substrate is placed on the substrate stage 102 . The pressure block 103 holds and heats the electronic element with the bumps formed on the circuit surface facing the mounting board. The mounting head 104 supports the pressure block 103 so that it can be raised and lowered toward the substrate stage 102 .

[0037] The mounting head moving mechanism 105 moves the mounting head 104 up and down. A mechanical stopper 106 is provided on the mounting head 104 to stop the pressure block 103 from descending. The mechanical stopper moving mechanism 107 adjusts the height position of the mechanical stopper 106 . The distance sensor 108 measures the height distance from the mounting head 104 to the pressure block 103 .

[0038] The control means 109 compares the height distance measured by the distance sensor 108 with a preset reference value A, and based on the comparison, causes the mechanical stopper moving mechanism 107 to adjust the height position, provided that the measured height distance (h) is greater than the reference value A.

[0039] As shown in FIG. 7, in the mounting system 101 according to the present disclosure, the mechanical stopper 106 is controlled to be raised by the distance by which the detected height (h) by the distance sensor 108 exceeds the reference value "A", that is, by the length (α1) by which the pressure block 103 thermally expands. As a result, in the mounting system 101 according to the present disclosure, the height position of the mechanical stopper 106 is adjusted by the mechanical stopper moving mechanism 107 only under specific conditions, which has the advantage of simplifying the control content compared to when the height position of the mechanical stopper is controlled at all times.

[0040] Third Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. FIG. 8 is a flowchart showing the steps of the electronic component mounting method according to the present disclosure.

[0041] [Step S1] The electronic element E is heated while being held by the pressure block of the mounting system with the bumps formed on the circuit surface facing the mounting board. The mounting system includes a substrate stage, a pressure block, a mounting head, a mounting head moving mechanism, a mechanical stopper, a mechanical stopper moving mechanism, and a distance sensor. A mounting substrate is placed on the substrate stage. The pressure block holds and heats the electronic element with the bumps formed on the circuit surface facing the mounting board. The mounting head supports the pressure block so that it can be raised and lowered relative to the substrate stage. The mounting head moving mechanism moves the mounting head up and down. A mechanical stopper is provided on the mounting head to stop the pressure block from descending. The mechanical stopper moving mechanism is capable of adjusting the mechanical stopper and the height position of the mechanical stopper. The distance sensor measures the height distance from the mounting head to the pressure block.

[0042] [Step S2] The pressure block is moved toward the mounting substrate.

[0043] [Step S3] On the condition that the height detected by the distance sensor is greater than a preset reference value, the height position of a mechanical stopper for stopping the descent of the pressure block is adjusted.

[0044] In the electronic component mounting method according to the present disclosure, it is possible to perform control to raise the mechanical stopper by the distance by which the height detected by the distance sensor exceeds the reference value, i.e., the distance by which the pressure block thermally expands. As a result, in the electronic component mounting method according to the present disclosure, the height position of the mechanical stopper is adjusted by the mechanical stopper moving mechanism only under specific conditions, which has the advantage of simplifying the control content compared to when the height position of the mechanical stopper is controlled at all times.

[0045] <Fourth embodiment> Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings.

[0046] As shown in FIG. 9, the control device 109' includes a comparison means 109A and a control means 109B.

[0047] The comparison means 109A compares the height distance (h) measured by the distance sensor of the mounting system with a preset reference value. The mounting system includes a substrate stage, a pressure block, a mounting head, a mounting head moving mechanism, a mechanical stopper, a mechanical stopper moving mechanism, and a distance sensor. A mounting substrate is placed on the substrate stage. The pressure block holds and heats the electronic element with the bumps formed on the circuit surface facing the mounting board. The mounting head supports the pressure block so that it can be raised and lowered relative to the substrate stage. The mounting head moving mechanism moves the mounting head up and down. A mechanical stopper is provided on the mounting head to stop the pressure block from descending. The mechanical stopper moving mechanism is capable of adjusting the mechanical stopper and the height position of the mechanical stopper. The distance sensor measures the height distance from the mounting head to the pressure block.

[0048] Based on the comparison by the comparison means 109A, the control means 109B causes the mechanical stopper moving mechanism to adjust the height position on the condition that the measured height distance (h) is greater than the reference value.

[0049] The control device 109' according to the present disclosure can perform control to raise the mechanical stopper by the distance by which the height (h) detected by the distance sensor exceeds the reference value, that is, the distance by which the pressure block thermally expands. As a result, the control device 109' according to the present disclosure adjusts the height position of the mechanical stopper using the mechanical stopper moving mechanism only under specific conditions, making the control content simpler compared to when the height position of the mechanical stopper is controlled at all times.

[0050] Fifth Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. The control method shown in FIG. 10 consists of the following steps.

[0051] [Step S11] The height distance measured by the mounting system is compared with a preset reference value. The mounting system includes a substrate stage, a pressure block, a mounting head, a mounting head moving mechanism, a mechanical stopper, a mechanical stopper moving mechanism, and a distance sensor. A mounting substrate is placed on the substrate stage. The pressure block holds and heats the electronic element with the bumps formed on the circuit surface facing the mounting board. The mounting head supports the pressure block so that the pressure block can be raised and lowered relative to the substrate stage. The mounting head moving mechanism moves the mounting head up and down. A mechanical stopper is provided on the mounting head to stop the pressure block from descending. The mechanical stopper moving mechanism is capable of adjusting the mechanical stopper and the height position of the mechanical stopper. The distance sensor measures the height distance from the mounting head to the pressure block.

[0052] [Step S12] Based on the comparison in step S11, the mechanical stopper moving mechanism is caused to adjust the height position on the condition that the measured height distance is greater than the reference value.

[0053] The control method according to the present disclosure can control the mechanical stopper to be raised by the distance beyond which the height detected by the distance sensor reaches the reference value, i.e., the distance by which the pressure block has thermally expanded. As a result, in the control method disclosed herein, the height position of the mechanical stopper is adjusted by the mechanical stopper moving mechanism only under specific conditions, making the control content simpler compared to when the height position of the mechanical stopper is controlled at all times.
