Vacuum soldering system VADU 200XL-W

Soldering of substrates and wafers in series production

The soldering system of type VADU 200XL-W is equipped with two separate process chambers and can be operated with paste as well as preforms.

The VADU 200XL-W enables the soldering of wafers up to 12 inch. Customized carriers are also offered by PINK.

This system allows the precise control of all relevant process parameters e.g. the temperature gradients during heating and cooling. Due to its intelligent temperature management the system provides short cycle times and an excellent temperature stability.
