Title:
METHOD AND APPARATUS FOR TESTING PRINTED CIRCUIT BOARD (PCB)
Document Type and Number:
WIPO Patent Application WO/2021/000842
Kind Code:
A1
Abstract:
A method for processing a printed circuit board (PCB), comprising: determining the position of a region to be tested (22, 41) on a PCB (S102); removing a designated layer (31; 51, 52) at the position, so as to expose a surface of an insulation layer (34, 55) to generate said region (22, 41) (S104); using an auxiliary image identifier (231, 232, 233; 421, 422) arranged around said region (22, 41) to make an adjustment and place a strain gauge on said region (22, 41) for adhesion (S106); and connecting a testing device to the strain gauge and testing said region (S108). Also disclosed is an apparatus for processing a printed circuit board (PCB). The present invention solves the problem of high costs caused by the fact that a PCB will be scrapped after testing in a traditional testing method, and achieves the effect of reducing PCB testing costs.
