Product Description

Etching machine is used to spray chemical solution to copper clad laminator, aluminum substrate or stainless steel plate, the exposed copper, aluminum, stainless steel are etched away, retain the pattern or circuit covered by the corrosion-proof film, so as to achieve the purpose of making pattern or circuit.

The etching machine is divided into acid etching machine, alkaline etching machine and hydrofluoric acid glass etching machine (the three kinds of etching machines can be provided by our company).

The acid etching machine is mostly used for etching the inner layer of the circuit board, and the production of small batches of various types of sample boards. Acid copper chloride is generally used (copper chloride is added with hydrochloric acid), which is characterized by easy control, small side corrosion, large amount of dissolved copper, easy regeneration and recovery, and the etching solution can achieve high quality etching under stable conditions.

The alkaline etching machine is used for the outer layer of circuit boards, large-scale double-sided board production, and the production of aluminum substrates. Its alkaline etching process has the advantages of cost saving and easy control.

Working process:Load → Etching → Recycle water rinsing → Tap water washing → Blot up → Unload
