Direct metal plating
Able to metal plate (LCP, COP, PI, PPE, ABS, etc) by maintaining smoothness.

【Feature】
1. Etching free of chromic acid and permanganate.Surface reforming by UV irradiation without etching of chromic acid and permanganate. Keeps material smooth surface.

2.Plating process for smooth surface helps easy to form fine circuit.
Plating process for smooth surface helps to reduce conductor loss and easy to form fine circuit.

3. Enabled plating to un-easy plating materials
Polyimide(PI)Liquid crystal polymer(LCP),Cycloolefin polymers(COP),Polyphenylene sulfide(PPS),Polyphenylene ether(PPE),Polyamide(PA),Polypropylene foam(PP),ABS(Acrylonitrile/Butadiene/Styrene),Polyester

  • 【Use Case】
    High frequency antenna
    Material: Cycloolefin polymers


  • For optical communication FPC board
    Material: Liquid crystal polymer


  • 3D board
    Material: Liquid crystal polymer

Cleaning and Reforming

Since the energy of UV (254 nm, 185 nm) is larger than the chemical bonding energy of organic materials such as resin, UV irradiation cleaves the bonds of organic substances, at the same time 185 nm produces ozone (O 3) from atmospheric oxygen. When this ozone is irradiated with 254 nm, active oxygen is generated. The active oxygen volatilizes and removes organic matter into a gas such as CO2 by a continuous chemical reaction. Further, radicals such as OH, COO, CO, COOH are formed on the resin surface due to the influence of active oxygen, thereby improving the adhesion, so the (reforming) effect appears.
