ALPHA SACX Plus 0807, Solder Alloy

ALPHA SACX Plus 0807/SACX Plus 0800 LEAD FREE SOLDER ALLOY DESCRIPTION ALPHA SACX Plus 0807 is a low silver lead-free alloy specially designed with proprietary additives to deliver soldering and reliability performance similar to higher silver SAC alloys (ie. SAC305, 405, etc). The SACX Plus 0800 variant is used to stabilize / reduce the copper content in the wave solder bath; this requirement will depend on process conditions. As with all Alpha Metals wave solder alloys, Alphas proprietary Vaculoy? process is used to remove certain impurities, particularly oxides. SACX Plus 0807 can be used for the widest range of assemblies and under the widest range of operating conditions of any low silver or silver free alloy available today. SACX Plus 0807 is available in a variety of forms including solid wire for replenishment and rework requirements. FEATURES & BENEFITS Feature Benefit Low Silver Content Lower material costs vs SAC305 Low Operating Temperature Requirement Wide processing window and energy cost savings. Drop in to most current lead free wave soldering machine temperature profiles Low Dross Rate Less dross means higher alloy utilization and less time spent on pot maintenance Low Copper Erosion Rate Less risk during high temperature, high exposure time processes (i.e. rework, selective soldering, etc...) Low Surface Tension Alloy Fast wetting with high wetting force delivering excellent hole fill and low SMD related defects Strong, Ductile Joints Lower warranty claims related to mechanical joint failures The proprietary Vaculoy process is a highly effective method for removing included oxides from solder. This is extremely important because included oxides generate excessive drossing and increase the viscosity of the solder. Solder with higher viscosity can result in increased soldering defects (i.e. solder bridging). APPLICATION ALPHA SACX Plus 0807is suitable for wave soldering and selective soldering for electronic assemblers interested in implementing a lead-free process. It is suitable for nearly all types of boards (single & double-sided) and works particularly well on assemblies with OSP pad finishes that have been exposed to prior reflow excursions and where lower silver or silver free alloys have not worked.
