Balver Zinn Solder Paste Cobar SP
The SP series of solder paste contains low melting temperature alloys. This series also is called Intrusol because of its benefits in intrusive soldering applications. The used alloys have melting temperatures starting from 138°C. To create a high-reliability solder joint, small additions of silver are inserted. There are three standard available alloys available: Bi58 (Bi58Sn42), BSA04 (Bi57.6Sn42Ag0.4) and BSA1 (Bi57Sn42Ag1).
