Sn95,5Ag3,8Cu0,7 (SAC387)

Lead-free solder bar, mainly intended for wave soldering, selective soldering, and dip soldering in soldering machines.

Product name: Sn95,5Ag3,8Cu0,7 (SAC387)
Alloy designation in accordance with ISO 9453: Sn95,5Ag3,8Cu0,7 (713)
Product type: solder bar

1. General characteristics

The lead-free solder alloy Sn95,5Ag3,8Cu0,7 is manufactured by Cynel-Unipress in the first smelting of tin, silver and copper. Its chemical composition complies with ISO 9453. The use of a continuous casting process ensures that the metal oxide formation in the solder alloy is minimized. As a result, the negative effect of the formation of dross in the soldering process has been significantly reduced. The product is designed for a wide range of industrial applications in electronics and electrical engineering where RoHS compliance is required. It can be sold on the consumer market and also used by private individuals outside professional applications.
