PCBs (Printed Circuit Boards) and PCBA (Printed Circuit Board Assemblies) serve distinct roles in electronics manufacturing. While PCBs are bare boards that provide electrical connections, PCBA refers to fully assembled boards with components, making them functional. The manufacturing processes differ significantly—PCB fabrication involves etching, drilling, and surface finishing, whereas PCBA includes solder paste printing, component placement, and reflow soldering.

Pourquoi les cartes de circuits imprimés (PCB) sont-elles le plus souvent vertes ? Le masque de soudure vert est largement utilisé, principalement parce qu'il protège efficacement le câblage de la carte contre les courts-circuits étrangers et qu'il recouvre également les fils de cuivre afin d'améliorer leur robustesse.
