Thermal Coupler Equipping Service

It is very important for the Semiconductor manufacturing process and the LCD or OLED manufacturing process to control the surface temperature of the wafer and glass panels. We offer the service to equip a thin cable of thermal coupler to the wafer or glass panel, and also provide the measurement data of the temperature map of these products.

A difference between current service and our offered service

In the past
  • Particle from fibrous insulation edge
  • Easy to break strand
  • Easy to get off by small contact area
Our service
  • Inhibiting particle from fibrous insulation edge
  • Using long life strand
  • Upgrading contact strength
  • High temperature response by extra fine-line thermal coupler
Thermal Coupler Wafer
