What Is Acid Etching

What Is Acid Etching

Acid etching is also called copper chloride acid etching system. It is usually used for single-sided etching, inner layer etching of multi-layer board or outer layer etching of Tenting process, because these processes use dry film or liquid photosensitive ink as etching resist. These photosensitive materials are relatively acid-resistant and not alkali-resistant, so acid etching is used.Types of acid etching:

  • H2O2/HCI series.
  • NaCIO3/HCl series.

In single-sided etching, acid etching is usually used, also known as copper chloride acid etching. When etching a multi-layer sheet, the sheet is treated with dry film or photosensitive ink, so the sheet is acid-resistant but not alkali-resistant, so it is called acid etching.

The process of acid etching is: pre-processing → coating → exposure → development → etching → ink removal.
