Soldering heat reliability ( DIP ) Reflow Temp / Time

Soldering Iron

Basic spec is ≦5 sec when 260℃.If temperature is higher, time should be shorter (+10℃→

-1sec). Power dissipation of Iron should be smaller than 15 W , and temperature should be
controllable. Surface temperature of the device should be under 230 ℃.

Rework

1. Customer must finish rework within 5 sec under 245℃.

2. The head of iron can not touch copper foil.

3. Twin-head type is preferred.
