Description

Technical Field

[0001] The utility model relates to the technical field of PCB, in particular to a micro-connection point structure of a PCB board. Background Art

[0002] At present, the PCB of the existing camera module is received from the supplier in full sheets. After receiving the materials, the PCB needs to be divided into individual pieces so that each individual PCB can be taken out for subsequent module assembly. The layout and connection method of each individual PCB in the whole sheet is to use micro-connection points. When the whole sheet is divided, it is only necessary to disconnect the micro-connection points between the individual pieces. However, after disconnection, the residual parts of the micro-connection points will often remain on both sides of the PCB, resulting in the PCB size exceeding the standard. This will cause low work efficiency, increase costs, and increase defects due to increased positions. Therefore, a micro-connection point structure of a PCB board is designed, which can facilitate the disconnection of micro-connection points and easily correct their residues. Utility Model Content
