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.
