Vacuum soldering unit

This unit melts solder under vacuum to remove voids from the solder.
Since solder is pre-heated in a reduction atmosphere, flux-free soldering is enabled.
Mostly, this unit has been used to manufacture power devices and form bumps for flip chip bonding .

Received the Award for Excellence at the 2nd Japan Manufacturing Awards.

Now accepting sample demonstration requests.
