Description

Technical Field

[0001] The utility model relates to the technical field of PCBA board production, and in particular to a PCBA board repair fixture structure. Background Art

[0002] PCBA (Printed Circuit Board Assembly) is a circuit board after the blank PCB (Printed Circuit Board Assembly) is mounted with SMT (Surface Mount Technology) patches and then DIP (Dual In-line Package). After the PCBA is generated, it is generally necessary to test its circuit function to determine whether the PCBA board functions properly. If the PCBA board is normal, it can be transferred to the next process; if there is a problem with the PCBA board, such as soldering leaks, wrong soldering, and self-damage of electronic components, the PCBA board will not be able to be used normally, which will cause waste of resources, product stagnation, cost loss, and other problems. The PCBA board must be repaired.

[0003] Generally speaking, PCBA board rework mostly adopts manual testing. The usual practice is to hold the board with one hand and connect the wires with the other hand, and use test tools (such as testers) to manually test and repair.
