5. Recommended Reflow Soldering Profile
AP.10H can be assembled following Pb-free assembly. According to the Standard IPC/JEDEC
J-STD-020C, the temperature profile suggested is as follows:
The graphic shows temperature profile for component assembly process in reflow ovens
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 over 270°C±10°C or 3 seconds, it will make cause component surface peeling or damage.
