Description

Technical Field

[0001] This utility model relates to the field of electronic components, and in particular to a component connection structure and a component connection structure manufacturing equipment. Background Technology

[0002] Component connection structures are a crucial part of electronic assembly, especially when connecting components on different circuit boards. Traditional component connection structures, such as the connection between memory modules and memory slots, or between graphics cards and graphics card slots, often rely on a structure called "gold fingers." Gold fingers consist of numerous golden-yellow conductive contacts, named for their unique gold-plated surface and finger-like arrangement, and are used to transmit all signals between two circuit boards.

[0003] In the assembly of modern electronic components, it is often necessary to reliably connect components located on different circuit boards, such as gold fingers or similar conductive contacts. A common connection method is to use ACF (Anisotropic Conductive Film). ACF is characterized by a significant difference in resistance between the Z-axis electrical conduction direction and the XY plane insulation. When the difference between the Z-axis conduction resistance and the XY plane insulation resistance exceeds a certain ratio, it can be considered to have good anisotropic conductivity.

[0004] like Figure 1 As shown, a plurality of first conductive contacts 3 arranged along the X-axis are connected to the first circuit board 6, meaning the components on the first circuit board 6 are arranged along the X-axis. A plurality of second conductive contacts 4 arranged along the X-axis are connected to the second circuit board 7, which is parallel to the first circuit board 6, meaning the components on the second circuit board 7 are also arranged along the X-axis. The number of each first conductive contact 3 and each second conductive contact 4 is the same, and each first conductive contact 3 and each second conductive contact 4 is arranged in a one-to-one correspondence. Each first conductive contact 3 and each second conductive contact 4 is connected through an ACF layer 8.

[0005] In existing technologies, such as Figure 1 As shown, the method of connecting each first conductive contact 3 and each second conductive contact 4 using the ACF layer 8 is as follows:

[0006] S1, the first circuit board 6 and the second circuit board 7 are separated from each other, and the ACF layer 8 is coated on each of the first conductive contact 3.

[0007] S2, connect each of the second conductive contacts 4;

[0008] Each first conductive contact 3 is provided such that the ACF layer 8 is located between each first conductive contact 3 and each second conductive contact 4;

[0009] S3, drive the second circuit board 7 to perform a false pressure towards the first circuit board 6;

[0010] S4, using a cutting head, drive the second circuit board 7 to perform a hot pressing operation on the first circuit board 6. Under the action of high temperature and cutting head pressure, each first conductive contact 3 and each second conductive contact 4 crushes the conductive particles located in the ACF layer 8. Since the ACF layer 8 is adhesive, each first conductive contact 3 and each second conductive contact 4 are bonded together through the ACF layer 8. Since the ACF layer 8 is conductive in the Z-axis direction and insulating in the X-axis direction, the first conductive contact 3 and the second conductive contact 4 arranged opposite to each other are electrically connected. The first conductive contact 3 is insulated from other first conductive contact 3 arranged side by side, and the first conductive contact 3 is insulated from the second conductive contact 4 arranged in a staggered manner.

[0011] However, Figure 1 The structure shown requires high precision in cutting head pressure during actual production. Insufficient pressure will prevent the first conductive contact 3 and the second conductive contact 4 from breaking down the conductive particles in the ACF layer 8, thus affecting the conductivity between them. Excessive pressure, on the other hand, can damage the first circuit board 6 and the second circuit board 7. Furthermore, the cutting head pressure and hot-pressing temperature differ depending on the type of first conductive contact 3 and second conductive contact 4 being processed. Therefore, the manufacturing process of connecting electronic components on different circuit boards using the ACF layer 8 requires precise control of both cutting head pressure and hot-pressing temperature. Moreover, adjustments to both pressure and temperature are necessary when hot-pressing different types of electronic components, such as gold fingers or similar conductive contacts. Utility Model Content

[0012] To address the problems existing in the prior art, the purpose of this utility model is to provide a component connection structure and a component connection structure manufacturing equipment, thereby reducing the requirements for hot pressing pressure and hot pressing temperature.

[0013] The objective of this utility model is achieved through the following technical solution:

[0014] A component connection structure includes a conductive layer, an adhesive layer, a first conductive contact, and a second conductive contact disposed opposite to the first conductive contact. The conductive layer is electrically connected to the first conductive contact and the second conductive contact, and the adhesive layer is bonded to the first conductive contact and the second conductive contact, respectively. The conductive layer and the adhesive layer are spaced apart.

[0015] Furthermore, at least two of each of the first conductive contact, the second conductive contact, the conductive layer, and the adhesive layer are provided, and each of the first conductive contact and each of the second conductive contact are arranged in a row in the same direction; each of the conductive layer and each of the adhesive layer are arranged in a row at intervals along the arrangement direction of each of the first conductive contact.

[0016] Furthermore, each of the conductive layers is electrically connected to a single first conductive contact and a single second conductive contact.

[0017] A component connection structure fabrication device includes a coating wheel. The coating wheel has a conductive paste outlet and an adhesive outlet on its sidewall, both arranged circumferentially on the coating wheel. The coating wheel rolls sequentially over rows of first conductive contacts. The conductive paste outlet coats each first conductive contact with a conductive layer, and the adhesive outlet coats each first conductive contact with an adhesive layer. The conductive layers and adhesive layers are arranged at intervals along the arrangement direction of the first conductive contacts.

[0018] Furthermore, the coating wheel has a receiving cavity, and a circular tube is provided in the receiving cavity. The circular tube divides the receiving cavity into a cylindrical cavity and a circular tube cavity. The cylindrical cavity is connected to the adhesive outlet, and the circular tube cavity is connected to the conductive slurry outlet.

[0019] Furthermore, it also includes a pressure sensor, a control unit, a conductive slurry supply unit, and an adhesive supply unit. The pressure sensor is installed in both the cylindrical cavity and the circular tube cavity. Each pressure sensor is electrically connected to the control unit. The conductive slurry supply unit and the adhesive supply unit are respectively electrically connected to the control unit. The adhesive supply unit is connected to the cylindrical cavity, and the conductive slurry supply unit is connected to the circular tube cavity.

[0020] Furthermore, there are at least two conductive slurry outlets and two adhesive outlets, and each of the conductive slurry outlets and each of the adhesive outlets is arranged sequentially at intervals along the circumference of the coating wheel.

[0021] Furthermore, the conductive slurry outlets and the adhesive outlets are spaced at equal intervals.

[0022] Furthermore, the first conductive contacts are spaced at equal intervals, and in the circumferential direction of the coating wheel, the distance between adjacent conductive slurry outlets and adhesive outlets is greater than or equal to the distance between two adjacent first conductive contacts.

[0023] Furthermore, there are at least two conductive slurry outlets and two adhesive outlets, and each conductive slurry outlet and each adhesive outlet is arranged in a row along the axis of the coating wheel.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: by splitting the ACF layer into a conductive layer and an adhesive layer that are spaced apart, when performing hot pressing operations between two oppositely arranged components, the accuracy requirements of hot pressing pressure and hot pressing temperature can be greatly reduced by selecting the adhesive layer that is easier to bond and the conductive layer that is easier to hot press. This makes it suitable for hot pressing connections between various components. Attached Figure Description

Detailed Implementation

[0035] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 2 and Figure 8 As shown, Figure 2This is a schematic diagram of two different electronic components bonded together, forming the component connection structure of this utility model. For ease of explanation, this utility model uses gold fingers in electronic components as an example. The component connection structure of this utility model is not limited to the connection between gold fingers, but can also be applied to the connection between various metal contacts. Specifically, this utility model discloses a component connection structure, including a conductive layer 1, an adhesive layer 2, a first conductive contact 3, and a second conductive contact 4 disposed opposite to the first conductive contact 3. One end of the first conductive contact 3 is electrically connected to a first circuit board 6, and the first conductive contact 3 and the first circuit board 6 cooperate to form a first gold finger. One end of the second conductive contact 4 is electrically connected to a second circuit board 7, and the second conductive contact 4 and the second circuit board 7 cooperate to form a second gold finger. In the first gold finger and the second gold finger, the first circuit board 6 and the second circuit board 7 are arranged in parallel. To achieve conductivity between the first conductive contact 3 and the second conductive contact 4, the conductive layer 1 is electrically connected to the first conductive contact 3 and the second conductive contact 4 respectively. To achieve the interconnection between the first conductive contact 3 and the second conductive contact 4, the adhesive layer 2 is bonded to both the first conductive contact 3 and the second conductive contact 4, and the adhesive layer 2 is insulating. To reduce the mutual influence between the conductive layer 1 and the adhesive layer 2 during the hot-pressing process of the component connection structure of this invention, specifically during the hot-pressing process of the first and second gold finger rows, the conductive layer 1 and the adhesive layer 2 are spaced apart. Meanwhile, as... Figure 8 As shown, the spacing between the conductive layer 1 and the adhesive layer 2 facilitates the use of a probe 11 to insert into the gap between the conductive layer 1 and the adhesive layer 2 to test the insulation of the adhesive layer 2.

[0039] For the preparation of conductive layer 1, a conductive paste can be selected. The conductive paste is a material formed by uniformly adding conductive powder to an adhesive and curing it to form a conductor. For the preparation of adhesive layer 2, A608Z2 adhesive can be selected. A608Z2 adhesive is a general-purpose industrial adhesive with strong adhesion, high cohesion, wide applicability, and is halogen-free, meeting new environmental protection requirements. It also has good usability, rapid surface drying in two to three minutes, minimal stringing, and can be applied vertically.

[0040] This invention splits the ACF layer 8 into a conductive layer 1 and an adhesive layer 2 spaced apart, allowing the first gold finger and the second gold finger to be hot-pressed together to form the component connection structure of this invention. By selecting the adhesive layer 2, which is easier to bond, and the conductive layer 1, which is easier to hot-press, the accuracy requirements for hot-pressing pressure and hot-pressing temperature are greatly reduced, making it suitable for hot-pressing connections between various electronic components.

[0041] Typically, various components have several conductive contacts, such as the conductive contacts arranged in rows on gold fingers. Figure 2As shown, at least two of each of the first conductive contact 3, the second conductive contact 4, the conductive layer 1, and the adhesive layer 2 are provided. Each of the first conductive contact 3 and each of the second conductive contact 4 are arranged in a row facing the same direction. Figure 2 In the middle, each first conductive contact 3 and each second conductive contact 4 are arranged in a row facing the X-axis. Each conductive layer 1 and each adhesive layer 2 are arranged in a row at intervals along the arrangement direction of each first conductive contact 3. Figure 2 In this arrangement, each conductive layer 1 and each adhesive layer 2 are also arranged in a row facing the X-axis. Between each opposing first conductive contact 3 and second conductive contact 4, there is at least one conductive layer 1 and one adhesive layer 2. Due to the presence of the adhesive layer 2, which has an insulating function, the sequentially arranged conductive layers 1 and adhesive layers 2 are equivalent to... Figure 1 In the ACF layer 8, the conductive layer 1 is only conductive in the Z-axis direction, while it is in an insulating state in the X-axis direction.

[0042] In some special cases, only one first conductive contact 3 and one second conductive contact 4 may be provided. In this case, one conductive layer 1 and one adhesive layer 2 may be provided, or multiple conductive layers 1 and adhesive layers 2 may be provided. When there is only one conductive layer 1 and one adhesive layer 2, it is sufficient to ensure that there is a gap between the conductive layer 1 and the adhesive layer 2. When there are multiple conductive layers 1 and multiple adhesive layers 2, it is necessary to ensure that each conductive layer 1 and each adhesive layer 2 is arranged in a row with intervals, and that each conductive layer 1 and each adhesive layer 2 is arranged sequentially on the plane of the first conductive contact 3. Each conductive layer 1 and each adhesive layer 2 may be arranged in a straight line or in a curved shape.

[0043] At the same time, under normal circumstances, such as Figure 2 As shown, each conductive layer 1 is electrically connected to a single first conductive contact 3 and a single second conductive contact 4. This is to prevent the conductive layer 1 from spanning two different first conductive contacts 3 and two different second conductive contacts 4, thus ensuring that the two different first conductive contacts 3 and two different second conductive contacts 4 are electrically connected to each other. However, in some special cases where it is necessary to ensure that two adjacent first conductive contacts 3 and two adjacent second conductive contacts 4 are electrically connected, the conductive layer 1 can also span between adjacent first conductive contacts 3 and adjacent second conductive contacts 4.

[0044] This utility model also discloses a component connection structure fabrication device for preparing the component connection structure of this utility model. For example... Figures 3 to 6As shown, the component connection structure manufacturing equipment of this utility model includes a coating wheel 5 and a driving mechanism for driving the coating wheel 5 to roll. The side wall of the coating wheel 5 is provided with a conductive paste outlet 5a and an adhesive outlet 5b, which are arranged circumferentially along the coating wheel 5. The coating wheel 5 rolls sequentially over each row of first conductive contacts 3. The conductive paste outlet 5a coats a conductive layer 1 on each first conductive contact 3, and the adhesive outlet 5b coats an adhesive layer 2 on each first conductive contact 3. The conductive layers 1 and adhesive layers 2 are arranged alternately along the arrangement direction of the first conductive contacts 3. This utility model, through the arrangement of the coating wheel 5 and the provision of conductive paste outlets 5a and adhesive outlets 5b on the side wall of the coating wheel 5, facilitates the coating of conductive layers 1 and adhesive layers 2 on each first conductive contact 3.

[0045] Since ACF is no longer used in the component connection structure of this utility model, the manufacturing process of the component connection structure of this utility model is different. This utility model also discloses a method for manufacturing the component connection structure, which is carried out in an automated production system. Taking the connection between gold fingers as an example, the component connection structure is as follows: Figures 2 to 8 As shown, the detailed preparation method is as follows:

[0046] Step 1: Identify the markers.

[0047] A single first gold finger is placed on a flat surface. The first circuit board 6 within the first gold finger has several first conductive contacts 3 arranged in a row. A machine identifies the first circuit board 6 and the first conductive contacts 3. When both the first circuit board 6 and the first conductive contacts 3 are in their designated positions, the process proceeds to step two.

[0048] Step 2: Apply conductive adhesive.

[0049] like Figure 6 As shown, the coating wheel 5 rolls sequentially over each of the first conductive contacts 3. During the rolling process, conductive slurry is discharged from the conductive slurry outlet 5a, thus forming a conductive layer 1 on each of the first conductive contacts 3; adhesive is discharged from the adhesive outlet 5b, thus forming an adhesive layer 2 on each of the first conductive contacts 3. The conductive layers 1 and adhesive layers 2 are arranged alternately to form a zebra stripe pattern. After the coating wheel 5 has rolled over each of the first conductive contacts 3, the process proceeds to step three.

[0050] Step 3: Automated optical inspection.

[0051] like Figure 7As shown, a track 9 is provided above the first circuit board 6, and the direction of the track is the same as the arrangement direction of each first conductive contact 3. A laser thickness gauge 10 is provided on the track 9. The laser thickness gauge 10 slides on the track 9 to measure the thickness of each conductive layer 1 and each adhesive layer 2, thereby determining whether the adhesive layer 2 has sufficient adhesion. If the laser thickness gauge 10 detects no abnormality, the process proceeds to step four; if the laser thickness gauge 10 detects an abnormality, an NG fault is reported, and the system shuts down.

[0052] Step 4: Insulation test.

[0053] like Figure 2 and 8 As shown, several probes 11 in the probe array are inserted into the gaps between each conductive layer 1 and each adhesive layer 2, and the conductivity between any two adjacent probes 11 is tested sequentially. Figure 8 As shown, a plurality of probes 11 include a first probe 11a, a second probe 11b, and a third probe 11c arranged adjacent to each other. During testing, a conductive layer 1 is provided between the first probe 11a and the second probe 11b, and an adhesive layer 2 is provided between the second probe 11b and the third probe 11c. When each probe 11 is energized, under normal circumstances, the first probe 11a and the second probe 11b are mutually conductive, while the second probe 11b and the third probe 11c are mutually isolated. If mutual conductivity is detected between the second probe 11b and the third probe 11c, an NG (Not Connected) error occurs. That is, when the conductivity of three adjacent probes 11 is tested pairwise, if both pairs are conductive, a fault occurs, and the system shuts down. Similarly, if neither pair is conductive, a fault is also determined, and the system shuts down. If one probe is conductive and the other is not, the process proceeds to step five.

[0054] Step 5: Apply dummy pressure

[0055] like Figure 2 As shown, each second conductive contact 4 is aligned with each first conductive contact 3, so that each second conductive contact 4 is in contact with the conductive layer 1 and adhesive layer 2 located on the first conductive contact 3, and each second conductive contact 4 is attached to the first conductive contact 3. The second circuit board 7 is then driven to press against the first circuit board 6. Then, proceed to step six.

[0056] Step Six: Heat and dry quickly.

[0057] The temperature of the conductive layer 1 and the adhesive layer 2 is increased to ensure a firm bond between the first conductive contact 3 and the second conductive contact 4, while maintaining conductivity between them. After heating is complete, the component connection structure of this invention is left to stand and allow the adhesive layer 2 to solidify.

[0058] In the component connection structure fabrication equipment of this utility model, many technical features, such as the internal structure of the coating wheel 5 and the number of conductive slurry outlets 5a, have multiple implementations. Below, for each of these technical features, including the internal structure of the coating wheel 5, one implementation will be described in detail. This implementation is referred to as this embodiment. Other implementations of the internal structure of the coating wheel 5 and other features are referred to as other embodiments, which will be briefly described below.

[0059] In this embodiment, as Figure 3 As shown, the coating wheel 5 has a receiving cavity, and a circular tube is provided inside the receiving cavity. The circular tube divides the receiving cavity into a cylindrical cavity 5c and a circular tube cavity 5d. The cylindrical cavity 5c is connected to the adhesive outlet 5b, and the circular tube cavity 5d is connected to the conductive slurry outlet 5a. This invention, through the arrangement of the cylindrical cavity 5c and the circular tube cavity 5d, makes the internal arrangement of the coating wheel 5 compact, maximizing the volume of the cylindrical cavity 5c and the circular tube cavity 5d. In other embodiments, a first cylindrical cavity and a second cylindrical cavity can also be provided. Both the first cylindrical cavity and the second cylindrical cavity are located within the coating wheel 5. When both the conductive slurry outlet 5a and the adhesive outlet 5b are provided, and the conductive slurry outlet 5a and the adhesive outlet 5b are symmetrically arranged along the axis of the coating wheel 5, the first cylindrical cavity and the second cylindrical cavity are also symmetrically arranged along the axis of the coating wheel 5. The first cylindrical cavity is connected to the conductive slurry outlet 5a, and the second cylindrical cavity is connected to the adhesive outlet 5b.

[0060] In this embodiment, as Figure 3As shown, the component connection structure fabrication equipment of this utility model also includes a pressure sensor, a control unit, a conductive slurry supply unit, and an adhesive supply unit. Pressure sensors are installed in both the cylindrical cavity 5c and the circular tube cavity 5d, and each pressure sensor is electrically connected to the control unit. The conductive slurry supply unit and the adhesive supply unit are respectively electrically connected to the control unit. The adhesive supply unit is connected to the cylindrical cavity 5c via a supply pipe 5e, and the conductive slurry supply unit is connected to the circular tube cavity 5d via a supply pipe 5f. Furthermore, the cylindrical cavity 5c and the circular tube cavity 5d employ the principle of communicating vessels, ensuring that the pressure is equal everywhere in both the cylindrical cavity 5c and the circular tube cavity 5d. The control unit sets the pressure setpoints for both the cylindrical cavity 5c and the circular tube cavity 5d. When the pressure sensor detects that the actual pressure value in the cylindrical cavity 5c is greater than the pressure setpoint, the control unit controls the adhesive supply unit to release pressure. When the pressure sensor detects that the actual pressure value inside the circular cavity 5d is less than the set pressure value, the control unit controls the conductive slurry supply unit to increase the pressure. Furthermore, when the coating wheel 5 is not performing coating operations, the control unit ensures that the pressure values ​​inside the cylindrical cavity 5c and the circular cavity 5d are the same as the external atmospheric pressure, preventing the conductive slurry in the cylindrical cavity 5c and the adhesive in the circular cavity 5d from overflowing from the coating wheel 5. In addition, controlling the set pressure values ​​inside the cylindrical cavity 5c, the circular cavity 5d, the rolling speed of the coating wheel 5, and the distance between the coating wheel 5 and the first conductive contact 3 allows for adjustment of the thickness of the conductive layer 1 and the adhesive layer 2. This invention, through the installation of a pressure sensor, facilitates the control of the spray pressure of the conductive slurry and adhesive, thereby controlling the thickness of the conductive layer 1 and the adhesive layer 2. In other embodiments, to reduce costs, a pressure sensor may be omitted.

[0061] In this embodiment, as Figure 3 and Figure 4 As shown, at least two conductive paste outlets 5a and adhesive outlets 5b are provided, and each conductive paste outlet 5a and each adhesive outlet 5b is arranged sequentially and at intervals along the circumference of the coating wheel 5. Therefore, the size of the coating wheel 5 does not need to be too small. In other embodiments, each conductive paste outlet 5a and each adhesive outlet 5b is arranged along the circumference of the coating wheel 5, but in order to increase the bonding effect, at least two adhesive outlets 5b are provided between every two adjacent conductive paste outlets 5a.

[0062] In this embodiment, as Figure 3 and Figure 4 As shown, the conductive paste outlets 5a and adhesive outlets 5b are equally spaced. Therefore, the spacing between adjacent conductive layers 1 and adhesive layers 2 is equal, facilitating conductivity testing by the probe 11. In other embodiments, the spacing between the conductive paste outlets 5a and adhesive outlets 5b may also be unequal.

[0063] In this embodiment, as Figures 3 to 6 As shown, the first conductive contacts 3 are evenly spaced, and in the circumferential direction of the coating wheel 5, the distance between adjacent conductive paste outlets 5a and adhesive outlets 5b is greater than or equal to the distance between two adjacent first conductive contacts 3. Therefore, when the coating wheel 5 rolls, the conductive paste and adhesive sprayed from the coating wheel 5 are not easily coated into the gaps between the first conductive contacts 3. In other embodiments, when the distances between adjacent conductive paste outlets 5a and adhesive outlets 5b in the circumferential direction of the coating wheel 5 are different, the spacing range between the first conductive contacts 3 can be limited to minimize the difficulty of coating the conductive paste and adhesive sprayed from the coating wheel 5 into the gaps between the first conductive contacts 3.

[0064] In this embodiment, as Figure 3 and Figure 4 As shown, at least two conductive paste outlets 5a and adhesive outlets 5b are provided, and each conductive paste outlet 5a and each adhesive outlet 5b is arranged in a row along the axis of the coating wheel 5. Therefore, when the coating wheel 5 rolls over each first conductive contact 3, conductive paste is sprayed from each conductive paste outlet 5a along the same axis of the coating wheel 5, and the sprayed conductive paste is interconnected to form a conductive layer 1. Similarly, adhesive is sprayed from each adhesive outlet 5b along the same axis of the coating wheel 5, and the sprayed adhesive is interconnected to form an adhesive layer 2. This invention, by sequentially providing multiple conductive paste outlets 5a or adhesive outlets 5b along the axis of the coating wheel 5, makes the coated conductive layer 1 or adhesive layer 2 strip-shaped, facilitating the connection between the first conductive contact 3 and the second conductive contact 4. At the same time, the spacing between each conductive paste outlet 5a arranged along the axis of the coating wheel 5 is the same, and the spacing between each adhesive outlet 5b arranged along the axis of the coating wheel 5 is the same. In other embodiments, the conductive paste outlet 5a and the adhesive outlet 5b may both be strip-shaped, and the length direction of the conductive paste outlet 5a and the adhesive outlet 5b is arranged along the axial direction of the coating wheel 5.

[0065] In summary, by dividing the ACF layer 8 into a conductive layer 1 and an adhesive layer 2 spaced apart, this invention significantly reduces the precision requirements for hot-pressing pressure and temperature during the fabrication of the component connection structure. The coating wheel 5 facilitates the coating of the conductive layer 1 and adhesive layer 2 onto each of the first conductive contacts 3. The cylindrical cavity 5c and the cylindrical tube cavity 5d maximize their volume. The pressure sensor facilitates control of the thickness of the conductive layer 1 and adhesive layer 2. The presence of several conductive slurry outlets 5a and adhesive outlets 5b spaced circumferentially on the coating wheel 5 eliminates the need for an excessively small size. The equal spacing between the conductive slurry outlets 5a and adhesive outlets 5b facilitates conductivity testing by the probe 11. By limiting the distance between adjacent conductive paste outlets 5a and adhesive outlets 5b to be greater than or equal to the distance between two adjacent first conductive contacts 3, the conductive paste and adhesive sprayed from the coating wheel 5 are less likely to be coated in the gaps between the first conductive contacts 3. Furthermore, by sequentially arranging multiple conductive paste outlets 5a or adhesive outlets 5b along the axial direction of the coating wheel 5, the connection between the first conductive contacts 3 and the second conductive contacts 4 is facilitated.

[0066] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
