According to the Standard IPC/JEDEC J-STD-020C, the temperature profile suggested is as follow: |Phase|Profile Features|Pb-Free Assembly (SnAgCu)| |---|---|---| |PREHEAT|Temperature Min(Tsmin)
Temperature Max(Tsmax)
Time(ts) from (Tsmin to Tsmax)|150°C
200°C
60-120 seconds| |RAMP-UP|Avg. Ramp-up Rate (Tsmax to TP)|3°C/second(max)| |REFLOW|Temperature(TL)
Total Time above TL (tL)|217°C
30-100 seconds| |PEAK|Temperature(TP)
Time(tp)|260°C
2-5 seconds| |RAMP-DOWN|Rate|3°C/second(max)| |Time from 25°C to Peak Temperature||8 minutes max.| |Composition of solder paste||96.5Sn/3Ag/0.5Cu| |Solder Paste Model||SHENMAO PF606-P26| 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.
