Features:
– Smooth, bright, well-formed fillets, free of micro-cracks, irrespective of the cooling rate
– Good through-hole penetration and topside fillet formation
– Low rate of copper leaching makes it easy to control the copper contents of the solder bath
– Lower aggressiveness to stainless steel and other solder pot materials as compared to tin-silver-copper alloys
– Slow, even growth of the inter-metallic layer at the solder/substrate interface
