Tips and Tricks for PCB Soldering
PCB soldering is an important skill. No one can solder the components perfectly every time, so we need to practice more. The following tips should help you to learn more about how to correctly solder so as to avoid some unnecessary damage.
1. Use heatsinks. Heatsinks are a must for the leads of sensitive components such as ICs and transistors. If you don't have a clip on heatsink, then a pair of pliers is a good substitute.
2. Keep the iron tip clean. A clean iron tip means better heat conduction and a better joint. You’d better to use a wet sponge to clean the tip.
3. Double-check joints. When assembling complicated circuits, it is good practice to check joints after soldering them. You can use a loupe to check the joint and a meter to check the resistance.
4. Solder small parts first. Solder resistors, jumper leads, diodes and any other small parts before you solder larger parts like capacitors and transistors. This makes assembly much easier.
5. Install sensitive components last. Install CMOS ICs, MOSFETs and other static sensitive components last to avoid damaging them during assembly of other parts.
