Pre - heating shall be done at +150˚C to 180˚C and for 120 seconds.
The temperature at capacitor Top shall not exceed +250˚C.
The duration for over +230˚C temperature at capacitor surface shall not exceed 30 seconds
The standard temperature profile differs by every reflow method.
Reflow shall be done within 2 cycles. please make sure the parts have enough
cooling down time between the first and second soldering process.
