# PCB Soldering and Prototyping

1. Flux is your friend
|
|
|
|
1. Use leaded solder - it has a lower melting temperature and makes rework much easier for prototype boards, especially with small pitch sizes on pads.

1. Temperature matters!
|
|
|
|
1. When reworking a part with a heat gun, bath it in heat with the tip held a couple inches away for 30 seconds or so first, then bring the tip closer. This will help prevent thermal shock. Same for cooling down. Most chips can only take 1 or 2 reworks before they're toast.
