What is PCB?

PCB (Printed Circuit Board), also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. Because it is made using electronic printing, it is called a “printed” circuit board.

What types of PCB materials can be cut with laser cutters?

Paper PCBs

This type of printed circuit board is made of fiber paper as a reinforcing material, soaked in a resin solution (phenolic resin, epoxy resin) and dried, then coated with a glue-coated electrolytic copper foil, and pressed under high temperature and high pressure. According to the American ASTM/NEMA standards, the main varieties are FR-1, FR-2, FR-3 ， XPC, XXXPC . The most commonly used and large-scale production are FR-1 and XPC printed circuit boards.

Fiberglass PCBs

This type of printed circuit board uses epoxy or modified epoxy resin as the base material of the adhesive, and glass fiber cloth as the reinforcing material. It is currently the largest printed circuit board in the world and the most used type of printed circuit board.

Composite PCBs

This type of printed circuit board is based on the use of different reinforcement materials to form the base material and the core material. The copper clad laminate substrates used are mainly CEM series, among which CEM-1 and CEM-3 are the most representative.

Metal PCBs

Metal substrates (aluminum base, copper base, iron base or Invar steel) can be made into single, double, multi-layer metal printed circuit boards or metal core printed circuit boards according to their features and uses.

Co2 laser cutter for PCB manufacturing

A CO2 laser cutting machine is used to cut PCBs made of nonmetal materials, such as paper, fiberglass, and some composite materials.

In addition to its ability to cut substrates, lasers can also be used for custom PCB prototyping, marking, engraving, drilling, or etching of individual material layers.
