Indium Corporation’s new SACM is a high-reliability solder alloy that offers drop shock performance far superior to other SAC alloys, without compromising on thermal cycling – all at a cost below that of typical SAC solder alloys. The solution meets the electronics assembly market’s demand for a solder alloy that offers the combination of good drop shock performance, good thermal cycling, lead-free composition, and reduced cost. The invention of SACM offers superior drop shock performance versus SAC305 and SAC105, with the added benefit of thermal cycling reliability equivalent to SAC305. This provides manufacturers with an affordable high-reliability SAC alloy. This development is especially meaningful for the manufacture of consumer electronics that normally see frequent handling, such as mobile devices. The solution is doped with manganese and contains less silver than other Pb-free alloys. Manganese provides increased strength and the reduced silver content provides a more stable cost structure, especially beneficial for cost-sensitive applications. According to Tim Jensen, global product manager for Indium Corporation’s PCB assembly products, “SACM provides manufacturers with a Pb-free alloy that offers greatly-improved reliability, while helping to control the cost volatility associated with traditional SAC alloys.”
