What are the precautions for etching

The method and effect of cleaning the mold of etching processing, etching processing uses a special mold, the cleaning agent of etching processing to clean the oil and impurities on the surface of the mold. What are the common defects of etching processing? A surface with oil has an anti-corrosion effect on the surface of the mold, which will cause uneven chemical corrosion, and it is not easy to stick protective stickers on the

The application of etching technology in the manufacture of sign plate

In the sign making industry, etching signs is a more common type of sign plate. Etching is the technique of removing materials using chemical reactions or physical impacts. Etching techniques can be divided into two categories: wet etching and dry etching. At present, etching signs mainly refer to metal etching signs, and there are also corrosion metal signs. The metal materials used are stainless steel, aluminum plate, copper plate and other metals

In-depth analysis of PCB etching process

It should be noted that the board at the time of etching has two layers of copper on top. In the outer etching process, only one layer of copper must be completely etched away, and the rest will form the final required circuit. This type of graphic plating is characterized by a copper-coated layer that exists only under the lead tin resist layer. Another process method is to coat the entire plate with copper, and the part outside the sensitive film is only tin or lead tin resist layer
