Abstract

A METHOD AND APPARATUS IS DISCLOSED WHICH ENABLES A PRINTED CIRCUIT BOARD (2) TO BE AUTOMATICALLY EXAMINED DURING ASSEMBLY AND BEFORE SOLDERING TO DETERMINE IF THERE ARE ANY MISSING PARTS (1,6) OR IF THE LEADS (3A,3B) OF THE RESPECTIVE PARTS (1,6) HAVE BEEN INCORRECTLY PLACED IN THE THROUGH HOLES (4) OF THE PRINTED CIRCUIT BOARD (2) OR UPON PADS (5B). AN ILLUMINATOR (11) ENABLES INCIDENT LIGHT RAYS TO BE REFLECTED FROM AN UNDERSIDE OF THE PRINTED CIRCUIT BOARD (2) FOR DETECTION BY ONE OR MORE CAMERAS (10). THE CAMERAS OUTPUT RESPECTIVE IMAGE SIGNALS WHICH ARE PROCESSED BY A PROCESSOR (12) TO DETERMINE IF PARTS ARE MISSING, LEADS ARE NOT PROPERLY POSITIONED OR THE LEADS ARE BENT. PRINTED CIRCUIT BOARDS FOUND TO HAVE DEFECTS ARE AUTOMATICALLY EXTRACTED FROM THE PRODUCTION LINE FOR RE-WORK.
