It was 10 years ago this fall when Alpha launched its innovative new lead-free, low-silver (Ag) solder alloy – Alpha SACX. This new alloy enabled the conversion from SnPb alloys to lead-free alloys in response to the RoHS regulations introduced in the European market. In addition to facilitating this transition, SACX offered the soldering performance of SAC305 at 30% lower cost, thus helping to shield electronic assemblers from Ag cost volatility. In addition, it produced tougher solder interconnects versus alloys without Ag, and significantly improved resistance to drop shock compared to higher Ag alloys.
“The original Alpha SACX alloy has evolved with the changing needs of our customers”, states Mike Murphy, Global Product Manager for Wave and Selective Solder alloys. “Over time we released various enhancements including our SACX Plus alloy suite – 0107, 0307 and 0807. These alloys were engineered to deliver a high level of soldering performance with just the right amount of silver depending on the type of assembly the customer was building. We also developed other products: solder pastes, cored wires, spheres, preforms and solid wires containing our SACX and SACX Plus alloys that have become industry standards. Leading global electronics manufacturers in many markets, including contract manufacturers, mobile devices, automotive, computer, telecom/telecom infrastructure, audio visual/gaming systems, white goods, equipment controllers, general lighting and LED lighting have relied on SACX and SACX Plus to assemble their electronic devices which touch the lives of millions upon millions of people around the world.”
The alloy suite is available worldwide as bar, solid wire, solder paste, cored wire, spheres and preforms, and are perfect together when used in combination. As with all Alpha wave solder alloys, our proprietary Vaculoy manufacturing process is used to maximize alloy purity.
