Hard Gold PCB

Cantidad : Proofing b   Precio : 200-1500CNY

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;

2. At present, the electroplating gold of the circuit board is mainly a citrate gold bath, which is widely used for its simple maintenance and simple and convenient operation;

3. Water gold content is controlled at about 1 gram / liter, PH value of about 4.5, temperature of 35 degrees, specific gravity of about 14 waves, current density of about 1ASD;

4. The main added drugs are acid-adjusted salt and basic-adjusted salt for adjusting pH value, conductive salt and gold-plated supplement additive for adjusting specific gravity, and gold salt;

5. In order to protect the gold cylinder, a citric acid dip tank should be added in front of the gold cylinder to effectively reduce the pollution of the gold cylinder and maintain the stability of the gold cylinder;

6. After the gold plate is electroplated, a pure water wash is used as the recovery water wash. At the same time, it can also be used to supplement the liquid level of the gold cylinder evaporation change. After the water is washed, it is connected with the second-stage counter current pure water wash. After the gold plate is washed, the alkali liquid is put into 10 g/shdter. To prevent oxidation of the gold plate;
