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 …

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 …

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 …

China successfully manufactured 5nm etching machine As far as the world’s chip field is concerned, of course, the United States is definitely in a leading position, but after entering the 5G era, China’s semiconductor chip strength should not be underestimated, and even ranked first in the world in the number of patents for related products. …

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 …

2000 China’s PCB production value of $ 3.635 billion , accounting for 8.7 % of global PCB output value , ranking fourth in the world . In China ‘s PCB output value , accounting for 83.5 percent of Guangdong . Therefore , the Guangdong region PCB plating is a great industry . According to incomplete …

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 …

Both zinc alkaline plating and acid zinc plating (chloride) can be applied to a wide variety of base metals and alloys. Choosing one over the other is largely a factor of the specific requirements of the coating, the base metal, and what will happen to the part after the plating process is complete. Part Requirements …

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 …
