Application of High Reliability Metallized Hole Technology

The metal-plated hole. Used for connection between inner and outer conductive graphics. In addition, the metallization technology of printed circuit board hole is one of the key technologies of printed circuit board manufacturing. Metallized hole refers to the hole wall between the top and bottom with a chemical reaction will be a thin layer of copper plated on the inner wall of the hole, making the printed circuit board top layer and the bottom layer connected to each other.
