30. HOW TO REPLACE FLAT PACKAGE IC
30.1. Preparation
- PbF (: Pb free) Solder
- Soldering Iron
Tip Temperature of 700°F ± 20°F (370°C ± 10°C)
Note: We recommend a 30 to 40 Watt soldering iron. An expert
may be able to use a 60 to 80 Watt iron where someone with less
experience could overheat and damage the PCB foil.
- Flux
Recommended Flux: Specific Gravity
Type
RMA (lower residue, non-cleaning type)
Note: See
ABOUT LEAD FREE SOLDER (PbF: Pb free)
30.2. Procedure
1. Tack the flat pack IC to the PCB by temporarily soldering two
diagonally opposite pins in the correct positions on the PCB.
Be certain each pin is located over the correct pad on the PCB.
2. Apply flux to all of the pins on the IC.
