Advances in laser soldering using high power diode lasers

Abstract

Laser soldering systems have been available for many years but the recent arrival of high power direct diode systems has given a boost to the acceptance of these systems by industry. Diode lasers are now being employed in industry for a range of soldering applications, most of these are the more challenging soldering applications where the controllability of laser processing is required and the diode laser brings added benefit to these. Very little work has been published on the quality of laser soldered joints and this paper addresses this shortfall by exploring laser parameters and joint quality using a number of techniques.
