Standard 2 Layer PCB production process The manufacturing process for a two-layer printed circuit board (PCB) involves several precise steps to ensure quality and functionality. It begins with cutting the board material according to customer specifications, followed by drilling holes as per engineering data. Next, electroplating is used to deposit a thin copper layer on the hole walls, and the circuit pattern is transferred onto the board. Graphics electroplating adds layers of copper, gold, nickel, or tin where needed, and etching removes unwanted copper. A soldermask is applied to protect the circuit, and a silkscreen is added for identification purposes. The board then undergoes 100% fly probe testing to detect any defects. Finally, a thorough inspection ensures all boards meet quality standards, with minor defects being repaired as necessary.
