[0022] The following is combined with Figure 1-4 This application is described in further detail.

[0023] The present application embodiment discloses a carrier board for PCBA patch processing. Figure 1-4 A carrier board for PCBA patch processing includes a carrier board body 1, a support board 3 and a support block 7. Conductive plates 2 are arranged on the upper and lower sides of the carrier board body 1. Welding holes 21 are opened inside the two groups of conductive plates 2. The support board 3 is arranged at the four corners of the carrier board body 1. The support board 3 is provided with a pillar 4 inside. One end of the pillar 4 passes through the support board 3 and is threadedly connected with a nut 5. The other end of the pillar 4 is connected to the outside. The support block 7 is arranged on the surrounding surface of the carrier board body 1. The support block 7 is provided in multiple groups. The outer surface of the multiple groups of support blocks 7 is provided with a protective plate 8;

[0024] Thus, during the implementation process, when the carrier body 1 needs to be processed, the worker picks up the carrier body 1, which usually uses glass fiber reinforced epoxy resin FR-4 as the material of the carrier board because it has good electrical properties, mechanical strength and high temperature resistance. The worker will contact the conductive plate 2, which is a covering member covering the surface of the carrier body 1. The worker welds the electronic components to the surface of the conductive plate 2 through the welding hole 21. The factory requires the surface of the conductive plate 2 to be covered with conductive material to increase the conductivity of the electronic components.

[0025] The four sides of the load-bearing plate body 1 are supported by the support plate 3, and the structure of the support plate 3 is consistent with that of the load-bearing plate body 1. The worker inserts the pillar 4 through the support plate 3 and fixes the pillar 4 with the nut 5 to facilitate the support of the load-bearing plate body 1. After the load-bearing plate body 1 is stable, it is convenient to weld the conductive plate 2 and the electronic components. After the conductive plate 2 is suspended and supported, the contact between the welding point of the electronic component and the workbench can be reduced, thereby reducing the impact on the safety of electric shock of the electronic components;

[0026] The surrounding surfaces of the supporting plate body 1 are covered with supporting blocks 7, and the protective plate 8 wraps the surfaces of the supporting plate body 1 and the supporting blocks 7. The protective plate 8 is made of insulating material to reduce the conductive performance. The protective plate 8 wraps the surrounding surfaces of the supporting plate body 1 to reduce the contact between the outer surface of the supporting plate body 1 and the user, reduce the risk of scratches and punctures, and increase safety.

[0027] Among them, an insulating layer 6 is provided on the surface of the support plate 3, and one side of the insulating layer 6 extends to the outer wall of one side of the conductive plate 2. The insulating layer 6 wraps the connection between the support plate 3 and the conductive plate 2. The support plate 3 is covered by the insulating layer 6, which reduces the contact between the surface of the support plate 3 and the air, reduces the conductivity during use, and increases the safety of the conductive plate 2 during use.

[0028] Preferably, the support column 4 includes a first threaded rod 41 slidably plugged with the support plate 3, one end surface of the first threaded rod 41 is threadedly connected to the nut 5, the other end of the first threaded rod 41 is fixedly connected to a connecting rod 42, one end of the connecting rod 42 away from the first threaded rod 41 is fixedly connected to a second threaded rod 43, and one end of the second threaded rod 43 is connected to the outside;

[0029] The four corners of the bearing plate body 1 are supported by the support plate 3. During use, the staff inserts one end of the first threaded rod 41 into the interior of the support plate 3, and the nut 5 is rotated and fixed on the surface of the first threaded rod 41. The nut 5 and the connecting rod 42 clamp the support plate 3, and the other end of the first threaded rod 41 is connected to the workbench through the connecting rod 42 to increase the stability of the bearing plate body 1 during the welding process.

[0030] Specifically, the four groups of support plates 3 are provided with insulating rings 31 inside, the insulating rings 31 are sleeved on the surface of the first threaded rod 41, and the insulating rings 31 protrude from one side of the support plate 3 and fit with the lower surface of the nut 5;

[0031] During use, the carrier plate body 1 is installed inside the electronic component through the support plate 3. The support plate 3 is isolated from the contact with the first threaded rod 41 by the insulating ring 31, reducing the friction of the surface thread of the first threaded rod 41 on the support plate 3, while reducing the contact between the conductive element and the support plate 3, thereby increasing the safety of the carrier plate body 1 during use. When the nut 5 is rotated and sleeved on the surface of the first threaded rod 41, it will fit with the outer surface of the insulating ring 31, thereby reducing the contact of the nut 5 on the support plate 3 and increasing the insulation performance of the support plate 3.

[0032] To be more specific, multiple groups of support blocks 7 are arranged around the conductive plate 2, and a gap is left between the support blocks 7 and the conductive plate 2. The support blocks 7 protect the surrounding surfaces of the supporting plate body 1. The support blocks 7 increase the structural strength around the supporting plate body 1, making the supporting plate body 1 less likely to deform. The conductive plate 2 is a conductive element. The gap between the support blocks 7 and the conductive plate 2 reduces the conductive performance of the element, reduces the contact between the conductive plate 2 and external electrical elements, and increases the safety of using the conductive plate 2.

[0033] Furthermore, in the implementation process, the protective plate 8 includes a shell 81 covering the surface of the support block 7, and a tightening plate 82 is provided on one side of the shell 81 close to the load-bearing plate body 1, and an inner wall of one side of the tightening plate 82 is in contact with the outer wall of the load-bearing plate body 1;

[0034] The protective plate 8 is composed of an outer shell 81 and a tightening plate 82. The outer shell 81 covers the surface of the load-bearing plate body 1 and the support block 7. The outer shell 81 and the tightening plate 82 are an integrated structure. The outer shell 81 reduces the contact between the burrs on the surface of the load-bearing plate body 1 and the support block 7 and the staff, thereby increasing safety.

[0035] The implementation principle of a carrier board for PCBA patch processing in an embodiment of the present application is as follows: when the carrier board body 1 needs to be processed during use, the worker picks up the carrier board body 1. The carrier board body 1 usually uses glass fiber reinforced epoxy resin FR-4 as the material of the carrier board because it has good electrical properties, mechanical strength and high temperature resistance. The worker will come into contact with the conductive plate 2, which is a covering member covering the surface of the carrier board body 1. The worker welds the electronic components to the surface of the conductive plate 2 through the welding holes 21. The factory requires the surface of the conductive plate 2 to be covered with conductive material to increase the conductive performance of the electronic components. The carrier board body 1 is supported by support plates 3 on all sides. The structure of the support plates 3 is consistent with the carrier board itself. The body 1 is consistent with the support plate 1, and the worker inserts the pillar 4 through the support plate 3 and fixes the pillar 4 with the nut 5 to facilitate the support of the load-bearing plate body 1. After the load-bearing plate body 1 is stable, it is convenient to weld the conductive plate 2 with the electronic components. After the conductive plate 2 is suspended and supported, the contact between the welding point of the electronic component and the workbench can be reduced, and the impact on the safety of electric shock of the electronic components can be reduced. The surrounding surfaces of the load-bearing plate body 1 are covered with support blocks 7, and the protective plate 8 wraps the surfaces of the load-bearing plate body 1 and the support blocks 7. The protective plate 8 is an insulating material to reduce the conductive performance. The protective plate 8 wraps the surrounding areas of the load-bearing plate body 1 to reduce the contact between the outer surface of the load-bearing plate body 1 and the user, reduce the risk of scratches and punctures, and increase safety.
