Principles of Operation
Overview
The principle of operation of the PDR IR Rework system is that whilst being heated from above and below, a single
SMD is subjected to similar temperature/time profile during rework, as it experiences during reflow in the original
production process.
Temperature Profile
In operation the component is put through a full ‘reflow’ procedure. The PDR Rework system uses a software
controlled system 5 or 6-stage process including 2 preheat stages, a soak zone, followed by reflow, final soak and
cooling stages. All parameters such as temperature levels and ramp rates are precisely controllable, as recommended
by board and component manufacturers.
