My friend had to repair his old gaming console the other day and he said that in most cases, the problems were actually caused by problems in the printed circuit board assembly. Actually, I never really know the mechanics behind this entire process and the reason why it matters. What is the process of a printed circuit board assembly and can you provide some basic tips so that I can make sense of it?

A printed circuit board (pcb) is simply a board with tracks on it that connect various electronic components together to make a circuit.
Your question seems very AI.
Basic tips so that you can make sense of it?, very strange question.
Tip 1,
An open circuit won’t work. Think of a light switch in the off position.
Tip 2,
Electronic components fail causing all sorts of devices to malfunction or not function at all.
Tip 3, Google is your friend.

It could well be caused by high current-carrying traces, This is common with large household appliances. Where a PCT relay contact carries high current.
To effect a repair, I replace the foil with a piece of copper solder dry-wick
