Abstract

The invention discloses a positioning reference point and method for improving cutting precision of a circuit board. The positioning reference points are arranged on a printed circuit board (PCB), the positioning reference points are hollow points and are made by use of the same process as cutting positions of the PCB, each hollow point is completed through primary punching and is arranged at a technical edge of the PCB as a cutting reference point, and thus the laser cutting precision is improved.

Description

Technical field [0001] The present invention relates to the electronics industry that has higher requirements for PCB segmentation and manufacturing, in particular to positioning reference points and methods for improving the cutting accuracy of circuit boards in the mobile phone camera PCB segmentation manufacturing industry, and solves the problem of PCB segmentation by designing positioning coordinates with higher accuracy. Inaccurate positioning coordinates caused by PCB deformation, expansion and contraction, etc. affect the cutting accuracy. Background technique [0002] With the gradual development of electronic products in the direction of fineness, smallness, lightness, and miniaturization, “dimensions” have become one of the important selling points of terminal products. The proposal of high quality and the application of high technology have also brought a lot to the manufacturing process. Series of new challenges. [0003] At present, the SMT process technology used as...
