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) ().
7.2. PROCEDURE

diagonally opposite pins in the correct positions on the PCB.
