Advantages of wet PCB etching The most important advantage of wet PCB etching is that it can be conducted in a normal atmospheric environment. High etching rate Low operational cost High selectivity: wet etching can be used to etch off a wide range of materials. Ease of equipment maintenance Disadvantages of wet PCB etching   …

Types of metal plating for high temperatures include: Nickel plating Nickel is a metal that is renowned for its hardness as well as excellent corrosion resistance, wear resistance, resistance to the elements. Nickel coatings are sometimes alloyed with tungsten, tin, boron and manganese to improve resistance to corrosion, hardness and conductivity further. Nickel plating is often used in …

How the exposure machine transfers the solder mask image to the panel. Method 1: Contact-film Technology Plot films containing the Soldermask image. Then send UV light through the film onto the panel thus exposing those area’s that are not black on the film. We call this the contact-film technology. On a high power conventional exposing machine we …

PCB ETCHING SPECIFICATION: PCB etching is a process of removal of unwanted copper (Cu) from the circuit board. When I say unwanted, it is nothing but the non-circuit copper that is removed from the board as per the PCB design. As a result, the desired circuit pattern is achieved. In other words, etching is like chiseling …

The use and precautions of the rolling shearing machine: ①The installation and disassembly of the cutter and the maintenance of the equipment, the equipment adopts 5 pairs of cutting discs, which is convenient for assembly and disassembly. The tool has been debugged and assembled on the cutter body when leaving the factory. Because the cutting …

Etching technology has become an indispensable special processing technology for metal product manufacturing because of its characteristics such as no molds, high-precision and high-density group hole processing, ultra-large format processing, and processing of various material hardness. At present, domestic and foreign etching technology and equipment mainly adopt wet technology including traditional chemical etching and electrolytic …

The linear gantry electroplating production line uses a gantry crane to lift the electroplated parts, PLC automatic control, and accurate operation; it can be equipped with a high-precision filter to ensure the high quality of the coating. The feature of the linear gantry electroplating production line uses a gantry crane to lift the electroplated parts …

The automatic gantry electroplating equipment production line adopts imported brake motors, so it has balanced walking, reliable brakes, and less shaking. In addition, it adopts computer control, so that it can change the process and procedures at will, and can change the electroplating type and electroplating time at any time. To meet the requirements of …

In the etching machine process, in addition to the overall etching method without any anti-corrosion treatment, it is necessary to pay attention to the “spread” problem of etching under the anti-corrosion layer, which is what we often call side corrosion. The size of the side corrosion is directly related to the accuracy of the graphics …
