Description

Technical Field

[0001] The utility model relates to a stacked PCBA board assembly, belonging to the technical field of PCBA board assemblies. Background Art

[0002] Printed Circuit Board Assembly (PCBA), or printed circuit board assembly, is the manufacturing process of assembling electronic components onto printed circuit boards. This process typically includes surface mount technology, plug-in processing, wave soldering, cleaning, and functional testing. The quality of PCBA production directly impacts the reliability and durability of the entire electronic product, so selecting the right materials and processes is crucial.

[0003] A Chinese patent publication (publication number: CN 220368851 U) discloses a PCB board stacking structure comprising six layers, namely, from top to bottom, the first layer, the second layer, the third layer, the fourth layer, the fifth layer, and the sixth layer. The first, third, and sixth layers are signal layers used to transmit signals between chips and devices on the PCB board. The second and fourth layers are ground layers, and the fifth layer is a power supply layer. A second dielectric layer is provided between the second and third layers, a third dielectric layer is provided between the third and fourth layers, and the third dielectric layer is a PP layer. A fourth dielectric layer is provided between the fourth and fifth layers, and the thickness of the second and fourth dielectric layers is 1 mil. This structural design eliminates the need for an additional optical plate between the third and fourth layers, while achieving the desired stacking thickness for a six-layer PCB board. This not only meets the impedance requirements of a six-layer PCB board, but also reduces the production cost of a six-layer PCB board.

[0004] However, when the above technology is used, since multiple PCBA boards work simultaneously, the temperature inside the placement board will rise, causing the PCBA board to be damaged and unable to continue to be used, increasing the cost of use and making replacement more difficult.

[0005] To this end, a stacked PCBA board assembly is proposed. Utility Model Content

[0013] Further preferably, the inner side of the protection block is arc-shaped, and the material of the protection block is soft rubber.

[0014] The embodiment of the present invention has the following advantages due to the adoption of the above technical solution:

The protection mechanism 5 includes a fixed plate 501, a push rod 502, a compression spring 503 and a protection block 504. The rear side of the compression spring 503 is fixedly connected to the inner wall of the cavity 4, and the rear side of the fixed plate 501 is fixedly connected to the front side of the compression spring 503. The rear side of the push rod 502 is fixedly connected to the front side of the fixed plate 501, and the front side of the push rod 502 extends through the cavity 4 to the front side of the positioning block 3.

The top of the placement plate 1 is fixed with mounting holes 8 all around. The inner side of the mounting hole 8 is provided with an internal thread 9. The inner side of the protective block 504 is arc-shaped, and the material of the protective block 504 is soft rubber.

[0029] Through the protection mechanism 5, when the PCBA board is placed, the surface of the PCBA board is clamped by the protection block 504, so that the PCBA board is stably fixed on the surface of the placement plate 1. By providing the plug-in slot 7, the placement plates 1 are stably fixed when multiple placement plates 1 are stacked to prevent shaking.

[0030] Example 2
