Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to a stacked PCBA (Printed Circuit Board Assembly) chip carrier. Background Art

[0002] PCBA refers to the entire process of a PCB blank board being assembled with components through SMT (a surface mounting technology) or through DIP (Dual In-line Package) plug-in components. After the PCBA is manufactured, the surface is uneven due to the protrusions of the mounted or plugged components, resulting in unstable placement of the PCBA on the carriers in the prior art.

[0003] In addition, since the PCBA needs to go through a baking process after being manufactured, the unstable placement of the PCBA on the carrier greatly affects the baking quality of the PCBA, and at the same time, the carriers for stacking the PCBA cannot be stably arranged. Therefore, there is a need to provide a stacked PCBA carrier that can solve the problems of unstable placement of the PCBA on the carrier and inability to stack the carriers in the prior art. Summary of the Invention

[0006] A stacked PCBA carrier includes a carrier main body and connecting columns; a number of first placement grooves are formed at intervals on the carrier main body, and the shape and size of the first placement grooves are the same as those of the PCBA, so that the PCBA can be embedded in the first placement grooves; a second placement groove is formed in the first placement groove, and the shape and size of the second placement groove match the shape and size of the components on the PCBA in the first placement groove, so that the components on the PCBA are fitted and embedded in the second placement groove; a number of connecting columns are respectively vertically connected to the bottom of the carrier main body, so that the upper carrier main body can be erected on the lower carrier main body through the number of connecting columns.

[0007] A number of corner grooves are formed on the carrier main body, and the corner grooves are located at the corners of the first placement grooves.

[0008] A number of clamping grooves are formed on the carrier main body, and the clamping grooves are located in the middle of the first placement grooves.

[0009] A plurality of the first placement grooves are arranged in a matrix, the clamping groove penetrates through the middle of the first placement grooves in the same row, and both ends of the clamping groove extend to the outside of the first placement grooves at both ends of the row.

[0010] The bottom cross-section of the connecting column is in a T-shaped structure, and a T-shaped groove is formed at the corner of the carrier body, so that the bottom of the connecting column can be inserted into the T-shaped groove in a matching manner, and a plurality of carrier bodies are vertically stacked through the connecting column.

[0020] Please refer to the attached Figure 1 and the attached Figure 2 , a stacked PCBA carrier, comprising a carrier main body 1 and connecting columns 2; a plurality of first placement grooves 4 are formed at intervals on the carrier main body 1, and the shape and size of the first placement grooves 4 are the same as those of the PCBA 3, so that the PCBA 3 can be embedded in the first placement grooves 4; a second placement groove 5 is formed in the first placement groove 4, and the shape and size of the second placement groove 5 match the shape and size of the components on the PCBA 3 in the first placement groove 4, so that the components on the PCBA 3 are fitted and embedded in the second placement groove 5; a plurality of connecting columns 2 are respectively vertically connected to the bottom of the carrier main body 1, so that the upper carrier main body 1 can be erected on the lower carrier main body 1 through the plurality of connecting columns 2.

[0021] Preferably, the carrier main body 1 and the connecting columns 2 can be integrally formed of steel materials. The size of the carrier main body 1 is adaptively made according to the volume of the baking equipment. The height of the connecting columns 2 can be determined according to the stacking height requirements. The connecting columns 2 at the bottom of the upper carrier main body 1 are erected on the lower carrier main body 1, ensuring the stacked arrangement of the carrier main bodies 1. Usually, the carrier main body 1 is of a rectangular structure, and a connecting column 2 can be provided at each of the four corners of the carrier main body 1.

[0022] Preferably, the number of the first placement grooves 4 on the carrier main body 1 is determined according to the area of the carrier main body 1 and the size of the PCBA 3, and the shape of the first placement grooves 4 is determined according to the shape of the PCBA 3, so that the PCBA 3 can be embedded in the first placement grooves 4, improving the placement stability of the PCBA 3 on the carrier main body 1 and preventing it from shaking during the movement process. The first placement grooves 4 on the carrier main body 1 can be the same or different to meet the placement requirements of different models of PCBA 3.

[0023] Preferably, the shape, size, and position of the second placement grooves 5 in the first placement grooves 4 can be determined according to the shape, size, and position of the components / inserted components on the PCBA 3, so that when the PCBA 3 is embedded in the first placement grooves 4, its components are exactly embedded in the second placement grooves 5, avoiding the problem of unstable placement of the PCBA 3 on the carrier main body 1 due to the protruding components, and further improving the placement stability and matching of the PCBA 3.

[0024] Please refer to the attached Figure 1 and the attached Figure 2 , a plurality of corner grooves 6 are formed on the carrier main body 1, and the corner grooves 6 are located at the corners of the first placement grooves 4.
