Notes on PCB Electroplating Lines

Today, I mainly introduce the precautions about PCB electroplating line. Have you paid attention to it? Precautions for electroplating line and safe production, emergency handling: (1) The copper strips of the auxiliary anode must be the same length as the production board, about 5 cm wide, and arranged close to the board. (2) The auxiliary …

The principle of dry etching

Plasma in dry etching The dry etching process uses the plasma after the dissociation of anion and anion particles in a gas to perform etching. The so-called plasma, 99% of the matter in the universe, is in the isoton state. It contains neutral particles, ions, and electrons, which mix together to appear electrically neutral. In …

Introduction to Dry Etching

With regard to etching, it refers to the process of selectively removing unwanted materials from the surface of a silicon wafer by chemical or physical methods. The basic purpose of etching is to correctly replicate the mask pattern on the glued (or masked) silicon wafer. About etching Etching refers to the process of selectively removing …

What is an etching machine used for?

The etching machine is mainly used in aviation, machinery and signage industries. It can etch patterns, patterns and geometric shapes on the surface of various metals and metal products, and can accurately hollow out. It can also etch and cut stainless steel, especially in semiconductors. In the process, etching is an indispensable technology. Etching refers …

What is Metal Finishing

Metal finishing is a type of surface finishing that can be defined as the deposition of a metallic coating onto a product either to enhance performance, function or aesthetic qualities while providing overall added value. While it’s not obvious on a daily basis, many objects have been subjected to metal finishing for use in our …

Alloys and metals used in plating

A wide variety of metals are used in plating components using the electroplating, electroless plating or selective plating processes. Often, the type of metal to be used depends on the type of application. Be it giving a finished metallic look to improve aesthetics, or be it changing the chemical, physical and mechanical properties of a component for …
