Defective surface mount components can be repaired by using soldering irons or using a non-contact rework system. A rework system is a better choice because SMD work with a soldering iron requires considerable skill, and in many cases is not feasible at all. There are essentially two non-contact soldering/desoldering methods—infrared soldering and soldering with hot gas. With infrared soldering, the energy for heating up the solder joint is transmitted by long or short wave infrared electromagnetic radiation.
Monday, February 11, 2013: Today, with technological advancements, one system unifies all essential process steps, offering manual to automatic soldering, desoldering and placement, requiring only little action from the operator. Let’s have a close look at some of the latest launches in rework systems.
Model: BR790-HD, Brand: Manncorp, Manufacturer: Manncorp, USA
Launched in December 2012, this high definition SMT rework station has split vision optics with a 1.3 million pixel, high definition video camera and five separate thermocouple inputs. These make BR790-HD a suitable solution for safe, repeatable, removal, alignment, placement, and soldering of BGAs, CSPs, ultra fine pitch QFPs and other delicate, heat sensitive, and expensive SMDs. Ultra sensitive Z-axis height sensing, controlled by optoelectronic switching, and a 6 zone rapid-IR underheater also contribute to performance that makes BR790-HD an advanced rework system.
