Pages 45-50 | Published online: 01 Nov 2011
 

Abstract

The special features of contact-reactive soldering of crystals to the bodies of devices are investigated. The methods of soldering crystals to the bodies of power semiconductor devices with the formation of the Si–Au, Al–Zn, and Zn–Sn eutectics are analysed. New methods of lead-free contact-reactive soldering of crystals with the formation of Si–Au, Al–Zn, Zn–Sn, and Al–Zn–Sn eutectics were developed and tested.
