Abstract
A laser solder-joint inspection system supplied by Vanzetti Systems, Inc., is being evaluated at the Electronics Manufacturing Productivity Facility of the Naval Weapons Center, China Lake, Calif. The automated inspection system determines solder joint quality by measuring the radiation emitted from a solder joint after laser stimulation. This paper describes the theory of operation of the system, discusses its strengths and limitations, and suggests possible modifications that might increase applicability of the system to a variety of inspection processes and needs.
