Abstract

Polytherms of the angles of wetting by Sn-Sr melts for aluminum films on silicon are investigated by the sessile drop method in helium. Such melts are promising for use as lead-free solders in electronics. It is found that the photon annealing of films enhances their wetting. Wetting thresholds are found at temperatures of >850 K for tin-strontium melts spreading over the surfaces of aluminum films on silicon that are preliminarily processed by photon annealing for 4 s.
