AIM Solder, a leading global manufacturer of solder assembly materials for the electronics industry, announces that Dr. Mehran Maalekian, AIM’s Research and Development Manager, presented his paper on lead-free solders at ICSR Toronto on May 20th, 2015. The International Conference on Soldering and Reliability has quality speakers every year covering topics such as; stencils for disparate-sized components, tin whiskers, head-in-pillow, and reliability issues. This year there were two speakers covering the topic of lead-free solders including AIM’s Mehran Maalekian.
Dr. Maalekian’s paper compared the physical, mechanical and soldering properties of three commercial lead-free solders; Castin, Babbitt and SAC-I and modifications of these alloys. In total, six alloys with compositions in the range of (major elements) Sn/Cu(0.7-4)/Ag(0-4)/Sb(0.5-8)/Bi(0-3)/Ni(0-0.15) were tested. Effects of alloying elements on the thermal behavior (melting and solidification), wetting force, contact angle, spreading, tensile and hardness properties were discussed. Based on preliminary results, the most desirable alloy modification was produced and its properties were compared against the commercial creep resistant solder alloy, i.e. SAC-I.
Dr. Mehran Maalekian is experienced in materials engineering with a focus on physical metallurgy, soldering, modelling in materials engineering, and thermo-mechanical processes. Since the start of his career Dr. Maalekian has received numerous recognitions such as; the National Sciences and Engineering Research Council of Canada Award, the Henry Granjon Prize, and IWS-Sossenheimer Award. Dr. Maalekian has been involved in numerous research studies and papers in the industry.
