'''2.''' When soldering, always avoid overheating. Electronic components doesn't like overheat! This is specially important when soldering the big connectors in the HifiBerry soundcard and the PiTFT touchscreen. If you overheat the circuit, probably you will break some electronic component and you will end with a dead board. I recommend  to use a fan while soldering. If not, you can use your mouth ;-) Also, don't solder the contacts in order. It's better to jump from one to another in the oposite corner. If you are not sure of your soldering skills, please, take your time and do some practice with inexpensive components and prototyping board.

'''2.''' Before soldering, please, check that you are soldering in the right side of PCB, also that components orientation is correct (ICs, diode)

'''3.''' After finishig the soldering, brush smoothly all the contacts. You may use a small iron brush. After that, blow over the circuit to remove any remaining tin.

'''4.''' Inspect visually all the soldered contacts. You could use a magnifying glass for verifying that every soldered pin looks good. If you are not sure, perhaps you could add more tin or re-solder the pin. Also, you could use a multimeter for testing the dubious contacts.

'''5.''' And of course, double-check everything! Assembling and wiring process are prone to errors. Don't be too confident ;-)
