28. HOW TO REPLACE FLAT PACKAGE IC

28.1. 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 0.82.
Type RMA (lower residue, non-cleaning type)

Note: See

ABOUT LEAD FREE SOLDER (PbF: Pb free)

().

28.2. 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.
