Assemblée PCB

Pourquoi un concepteur de PCB utiliserait-il du cuivre plus épais que la normale pour la conception d'une carte de circuit imprimé?

Thicker copper is used on circuit boards that must carry a relatively large amount of current, in a small board area. PCB manufacturers can “plate up” or add more copper to the board, allowing greater current carrying capacity in the finished board.

En d'autres termes, the circuit board is “resisting” the tendency to burn up under high load.

Another trick that is often used, for example in PC power supplies, is to leave parts of the high-current traces exposed, so they can accumulate solder during the wave soldering process.

All that additional solder is a cheap & easy way to add metal to the board, increasing its ability to conduct greater current flows.
