Vacuum Reflow Solder Oven for up to 300 x 300 mm substrate size and temperature up to 450 °C

Application: 

Perfect for solder processes with substrate size up to 300 mm x 300 mm.

Due to the gas sealed separation of the working capacity (chamber) from the lamp fields this is a perfect tool for contaminating processes. The chamber parts can be easily cleaned.

Through the chamber walls there can be led different feed throughs, like window for optical measurement tools, thermocouple feed through, gas inlets, etc.
The process cycles are very short due to the fast pump-down time to 10e-3 hPa.

Here are the most common applications:

  • Solder Reflow with and without flux
  • Wafer bump and solder ball reflow
  • Flip Chip
  • Encapsulation and sealing of housings
  • High Power LED module
  • resistor paste firing
  • IGBT/DBC
  • Die attachment

Chamber:

  • Chamber size: 350 x 350 x 50 mm (optional up to 120 mm)
