Tongling Preferred Circuit Board Copper Foil Price
The commonly used reinforcement materials of copper clad laminate are alkali free (alkali metal oxide content shall not exceed 0.5%) glass fiber products (such as glass cloth, glass felt) or paper (such as wood pulp paper, bleached wood pulp paper, cotton wool paper). Therefore, laminates can be divided into glass cloth base and paper base.
