Composition of solder paste
Solder Paste Model
Soldering Iron condition: Soldering iron temperature 270°C±10°C.
Apply preheating at 120°C for 2-3 minutes. Finish soldering for each terminal within 3 seconds, if soldering iron
temperature over270°C±10°C or 3 seconds, it will make cause component surface peeling or damage.
