May 08, 2024 | S.Kanimozhi, Dr. K.Gopala Krishnan

A Printed Circuit Board is used to mechanically support and electrically connect electronic components using conductive pathways, track or signal traces etched from copper sheets laminated on to anon conductive substrate. The automatic inspection of PCBs serves a purpose which is traditional in computer technology. The purpose is to relieve human inspectors of the tedious and inefficient task of looking for those defects in PCBs which could lead to electric failure. This paper is a survey conducted on various existing approaches which performs automatic testing on PCB.
