What is copper clad in PCB?
Copper Clad Laminate, abbreviated to CCL, is a type of base material of PCBs. With glass fiber or wood pulp paper as reinforcing material, a copper clad board is a type of product through lamination with copper clad on either one side or both sides of reinforcing material after being soaked in resin
It is easily bonded to the insulating layer and able to be printed with a protective layer and form circuit pattern after etching. Copper foil has low rate of surface oxygen and can be attached with a variety of different substrates, such as metal, insulating materials.
