Abstract:
A gold-plating etching process for 5G high-frequency signal boards is carried out according to the following steps: the outer dry film, the plug gold-plating, the film removing, and the alkaline etching The alkaline etching solution comprises 100 to 150 g/L. of cupric chloride, 90 to 120 g/L of ammonium chloride, and ammonia. The pH value is 9.6 to 9.8. The ratio of the ammonia and the alkaline etching solution is (550-800):1000. The present invention provides a gold-plating etching process of 5G high-frequency signal boards. The alkaline etching procedure is performed right after gold-plating, eliminating the outer etching process after gold-plating. Costs of the outer film pressing, the exposure, and the development can be saved. The flow rate is improved. Requirements of 5G communication circuit boards are satisfied. That is, the transmission speed of 5G communication high-frequency signal boards of the present invention is fast.

Claim (Index 3):
The gold-plating etching process for 5G communication high-frequency signal boards according to  claim 1 , wherein\n in the step of plug gold-plating, the nickel-plating solution used in the process of nickel-plating comprises 250 to 300 g/L of nickel sulfate hexahydrate, 35 to 45 g/L of nickel chloride hexahydrate, 35 to 45 g/L of boric acid, and brightener; and a ratio of the brightener to the nickel-plating solution is (30-35):1000.
