February 21, 2015: Defective surface mount components can be repaired by using soldering irons or a non contact rework system, the latter being the preferred option. There are fundamentally two non contact soldering/de-soldering methods— infrared soldering and soldering with hot gas. In the case of the former, the energy for heating up the solder joint is transmitted through long or short wave infrared electromagnetic radiation.
Nowadays, with technological advances, one system integrates all the necessary process steps, offering manual and automatic soldering, de-soldering and placement. Such systems require minimal operator activity. Let’s look at some of the latest launches among rework stations.
