A Copper Clad PCB Board is a type of printed circuit board (PCB) that has a thin layer of copper deposited on one or both sides of the board. The "double-sided" designation means that there is copper on both sides of the board, and the "100x150mm" measurement refers to the dimensions of the board. These boards are commonly used in electronic devices and circuit projects due to their ability to efficiently conduct electricity.

Copper clad boards are used to create your own professional PCBs.

Copper-clad steel (CCS), also known as copper-covered steel or the trademarked name Copperweld is a bi-metallic product, mainly used in the wire industry that combines the high mechanical resistance of steel with the conductivity and corrosion resistance of copper.

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 CCL 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.
