After designing, fabricating, and assembling circuit boards, what should follow is inspection. Manufacturing processes often have errors, so you do not want to label, package an assembled board that is not fully functional. For this reason, you will need large scale PCB inspection services. There are many firms that can help you inspect your PCBs, so you only need to take your time to do some research before you decide to hire a particular firm.
When inspecting an assembled PCB, you must look at the output signals as well as the continuity of conducting paths and the general condition of the PCB. It requires a lot of manpower and special equipment to test an assembled PCB. After inspection, defective boards can either be discarded or returned to the assembly line for proper assembly. Only well-equipped service providers with a lot of experience in the industry should be shortlisted.
