Solder is designed for higher application temperatures. The wetting speed, the area of spread, the contact angle and the shear strength of joints meets the strictest industrial crieteria. It is applicable in the electronics, energy industry and many specific purposes and applications including research and development. It allows direct soldering of metallic materials with non-metallic or special materials (like tungsten). Primary designed for ultrasound, laser and combined soldering it is usable in sequent and selective soldering process. It is also suitable for soldering without flux.
