Photochemical etching is known by various names, such as chemical grinding, metal engraving, chemical processing, chemical engraving, and optical machines. This process can be wet or dry. Wet stamping is the procedure in which the metal is dissolved in a chemical solution. In the case of dry stamping, the substance dissolves with the help of steam or ions.
The entire optical etching process is a combination of basic etching and photolithography. In the photolithography process, patterns are created by the interaction of enzymes in the molecules or by the use of anti-layer substrates. In this way, the photo resistance develops while the substrate is exposed to ultraviolet radiation. Then the substrate is drilled. photo resistance helps protect parts from substrates that do not need to be dug. This is a very useful way today to create common fingers or circuit board protectors.
Gray colors can be obtained by chemical photo-milling by drilling the panels multiple times to create different depths of the plate. This process allows the creation of complex details with difficulty in reproduction.
This method has been able to define a broad market for itself primarily based on its function, and the drilling procedure is now approved in various manufacturing units, electronics and metallurgical industries, and in some cases also in aircraft and space. This method is also known as chemical photo grinding or chemical photo etching. The electronics manufacturing industry has made extensive use of this process with its quality and high level of precision.
The complete method of engraving photo is not very difficult. It is very useful for metal components, especially when a large production work is required. The procedure helps to create templates, circuit boards, mechanical models, etc. The complete optical engraving method requires a lot of attention and careful control. The process is fast and requires a very low cost configuration. Various minerals such as stainless steel and corrosion resistant alloys can be used for drilling. Even very fine metals or chips, solid or brittle materials can undergo this process.
With the production of positive plates and the production of traditional printing plates, a positive film is used as the original, that is, the black and opaque parts of the film are joined by surface elements that accept ink on the plate.
In the case of making negative plates with “negative plates”, a negative film is used as the original, that is, the image fields that accept the ink from the printing plate correspond to the transparent and transparent areas of the film.
To ensure quality and control during panel manufacturing, controls are copied to
dishes
These days there are also waterless offset printing plates coated with a thin layer of silicone that resists ink. A series of lasers remove the silicone layer from the image regions.
The photo pattern meets the immense requirements of RF shielding, EMI shielding, circuit board etc. Finger stockings are widely used in electronic products mainly due to high conductivity. It is predominantly made of beryllium copper and does a good job of chemical drilling. Use this process for great benefits if you work in the field of electronic manufacturing.
