ALPHA® Vaculoy SAC300,305,350,400,405LEAD FREE WAVE SOLDER ALLOYDESCRIPTIONSn96.5Ag3Cu0.5 and Sn95.5Ag4Cu0.5 and their replenishment alloys Sn97Ag3Cu0, Sn96.5Ag3.5Cu0 and Sn96Ag4Cu0 are leadfreealloys suitable for use as a replacement for Sn63 alloy. The replenishment alloys are sometimes used to stabilize / reduce thecopper content in the wave solder bath, this requirement will depend on process conditions. As with all Alpha Metals bar solder,Alpha€™s proprietary Vaculoy® alloying process is used to remove certain impurities, particularly oxides.FEATURES & BENEFITSFeaturesô€‚‰ Yield €“ Best in class yield, out performs all Sn/Cu based materialsô€‚‰ Wetting speed €“ fast wetting, in back to back tests 0.65s compared to 1.00s, for Sn/Cu based materialsô€‚‰ Dross generation €“ Low dross generation delivered by Vaculoy alloy conditioningBenefitsô€‚‰ Excellent solderability due to fast wetting speedô€‚‰ Very good drainage, has lower levels of bridging compared to Sn/Cu alloysô€‚‰ Delivers excellent performance across a wide range of Flux technologiesThe proprietary Vaculoy process is a highly effective method for removing included oxides from solder. This is extremelyimportant because included oxides generate excessive drossing and increase the viscosity of the solder. Solder with higherviscosity can result in increased soldering defects (i.e solder bridging)APPLICATIONSn96.5Ag3.0Cu0.5 and Sn95.5Ag4Cu0.5 are suitable for wave soldering and surface mount applications for electronicassemblers interested in implementing a lead-free process. A solder pot temperature of 255 - 265°C (491-509°F) isrecommended. For suitable wave solder fluxes, please see our selector guide. Lead free Reclaim services including dedicatedlead free containers are also available, please consult your local sales office.AVAILABILITYVaculoy is available in 1 kg (2.2lb) Bars, feeder Ingots and autofeed wire. Most products are shipped strapped and palletized orpacked in corrugated cardboard box with no remarkable damages in appearance.HEALTH & SAFETYPlease refer to MSDS for advice on proper handling and safety instructions.The information contained herein is based on data considered accurate and is offered at no charge.
