Rigid Board Electroless Nickel and Immersion Gold
Zhengtianwei has gained a complete and well-performed series of electroless nickel and immersion gold technology after years of improvement and breakthrough. The technology is suitable for all kinds of PCB laminate, including electroless nickel and immersion gold treatment. It not only deposits uniform nickel crystalloid, but also the phosphorus structure maintains excellent weldability.
- Product Features
- Product Advantage
