Hard Gold PCB, immersion gold pcb, is to immerse the board in the plating tank and apply current to form a nickel-gold coating on the copper foil surface of the board. The electro-nickel gold is characterized by high hardness, wear resistance and oxidation resistance. Widely used in applications.
Introduction to gold plated circuit board Technology:
1. Purpose and role: gold as a precious metal, has good weldability, oxidation resistance, corrosion resistance, small contact resistance, good wear resistance of the alloy and so on;
