ALPHA SACX 0307, Solder Alloy

ALPHA SACX 0307, 0300 LEAD FREE WAVE SOLDER METAL DESCRIPTION ALPHA SACX 0307 is a lead-free alloy suitable for use as a replacement for Sn63 alloy in the wave solder process. The SACX 0300 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 bar solder, Alphas proprietary Vaculoy alloying process is used to remove certain impurities, particularly oxides. The product is further enhanced with the addition of 2 minor elements to reduce dross formation and improve the joint cosmetics. FEATURES & BENEFITS Features: ? YIELD Comparable to SAC305, superior performance for bridging compared to Sn99.3/Cu0.7 based alloys. ? WETTING SPEED 0.75 seconds typical wetting speed compares to SAC305 at 0.65 sec and superior to Sn99.3/Cu0.7 based alloys at 1.0 sec. ? DROSS GENERATION lowest in class due to the Vaculoy process in conjunction with the addition of a dross reducing agent. Benefits: ? Lowers Total Cost of Ownership due to the lower material cost, high yields and low dross generation. ? Gives very good solderability due to the fast wetting speed. ? Gives very good drainage and hence lower levels of bridges due to the formulation containing Silver. ? Delivers good performance across a range of flux technologies. 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 0307 is suitable for wave soldering and surface mount applications for electronic assemblers interested in implementing a lead-free process. It is suited to single side and mixed technology boards. A solder pot temperature of 255 - 265C (491 509F) is recommended with a contact time 2.3 3.5 seconds.
