PCB factory china tells you Basic standards for electrical testing process
Any pad found on the PCB by the solder mask must belong to the test pad of a certain component or circuit. In both cases, it is necessary to check their electrical conductivity and electrical isolation from other pads and the traces connecting them. Usually, the information is extracted by the PCB factory china that provides this service from the following files sent by the customer to the production:
Gerber file, corresponding to the solder mask. Need to determine where the test leads should be placed.
Drill files. Its processing can accurately calculate the available copper area around the perforation, thereby preventing the test lead from entering and destroying it or generating errors.
Copper layer file. Outside, top and bottom, and inside (if any).
The electrical test system uses this information to extract a list of electrical networks corresponding to our card, so that it can verify its integrity based on conductivity and insulation.
