3-38 Component Description
3.12.2.1 Contact Heaters
A contact heater (Figure 3-24) consists of an interchangeable top plate mounted on a heating unit. Each
top plate is equipped with vacuum ports that hold the workpiece against the heater during the heating
process. The heater is secured by fasteners on the top of a lift table and connected to power and air
supplies using quick-disconnect fittings.
Contact heaters use conduction as the heat transfer method. This type of heating is best used when there
are no, or few, components on the bottom side of the board. When there are bottom board components,
the top plate must be compatible with workpiece configuration if uniform heat transfer is to occur.
