Cast-In Thermal Platens for Wave Solder & Reflow Surface Mount Equipment
Tempco’s highly engineered platens are capable of maintaining a temperature gradient of 5°F (2.77°C) across the entire working surface of the heater platen at the process operating temperature. The innovative design of this cast-in thermal platen incorporates the dual functions of being both a radiant and a convection heat source.
Cast-In Heaters for Wafer Processing
Tempo offers a complete selection of highly customized semi-conductor process heaters which include:
