'''1.''' Be careful with your fingers. Your body can hold a good amount of static electric charge. Under some circumstances that charge can be drained through some of the components that you are handling and this could break the component. Try to hold the PCBs by the borders and discharge your body frequently touching some "ground" with your fingers.
2. 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. And of course, double-check everything! Assembling and wiring process are prone to errors. Don't be too confident ;-)
