What materials are printed circuit boards made of?

PCB boards are made of: organic material phenolic resin, fiberglass, epoxy resin, inorganic material aluminum.

PCB board main advantages are.

1, because the graphics have repeatability and consistency, reducing the wiring and assembly errors, saving equipment maintenance, debugging and inspection time.

2, the design can be standardized, conducive to interchangeability.

3, high wiring density, small size, light weight, conducive to the miniaturization of electronic equipment.

4, conducive to mechanization, automated production, improve labor productivity and reduce the cost of electronic equipment.
