Infrared Soldering System

---

The customers product required an operator to insert approximately six(6)
wires into plated holes of a printed circuit board.

The operator then placed the product into a fixture, which by means of 
an air cylinder moved at a constant speed, under a stylus which dispensed
solder paste over the wires on the board. 

At the same time the previous unit was being soldered by means of a non-contact infrared line heater.

A metal mask ensured radiant heat did not cause any damage to the rest of
the assembly. This process eliminated the tinning, maintainance of soldering irons and
improved the reliability of solder joints.
