ALPHA® SLS 65 is an active, low solid, no-clean flux. It is formulated with a proprietary mixture of organic activators. Several proprietary additives are formulated into ALPHA® SLS 65, which act to reduce the surface tension between the solder resist and the solder, thereby dramatically reducing the tendency of solder ball generation. The formulation of ALPHA® SLS 65 is also designed to be more thermally stable, thereby reducing the occurrence of solder bridging.
