Technical Field

[0001] The present application relates to the technical field of PCBA processing equipment, and in particular to a PCBA patch processing jig. Background Art

[0002] PCBA stands for Printed Circuit Board Assembly, which is the process of soldering various electronic components (such as chips, resistors, capacitors, connectors, etc.) to a printed circuit board (PCB) and connecting them to achieve electrical connections. PCBA is a crucial step in the manufacture of electronic products. During PCBA patch processing, in order to ensure the accuracy of the position of the printed circuit board, it is necessary to use the PCBA patch processing jig to fix the position of the printed circuit board. These jigs are usually made of metal or plastic, with slots for fixing the printed circuit board, as well as positioning guides and clamping devices. During the patch processing process, the operator places the printed circuit board on the jig, then places the components in precise positions on the PCB board, and finally fixes the components on the PCB board by heating or other methods.

The utility model has a simple structure and is easy to operate. The piston shaft of the electric push rod extends through the L-shaped clamping plate to clamp the PCBA patch.
