SCA0703

Standard alloy for selective, dip and wave soldering

BALVER ZINN alloy SCA (SnCu0,7Ag0,3) is an inexpensive standard alloy when no special reliability requirements are made.

SCA0703 can be used for wave soldering, selective soldering and dip tinning as long as the significant copper dissolution does not affect the reliability and serviceability of the solder joint. Particular care must be taken with thin conductors in the pad area and especially with thin enameled copper wires. The use of the proven Balver Zinn alloy SCAN-Ge0703 is recommended to significantly reduce copper dissolution.
