What are the types of PCB circuit board processing
At present, the country has higher and higher requirements for environmental protection and greater efforts in link governance. This is a challenge but also an opportunity for PCB factories. If PCB factories are determined to solve the problem of environmental pollution, then FPC flexible circuit board products can be at the forefront of the market, and PCB factories can get opportunities for further development.
The Internet era has broken the traditional marketing model, and a large number of resources have been gathered together to the greatest extent through the Internet, which has also accelerated the development speed of FPC flexible circuit boards, and then as the development speed accelerates, environmental problems will continue to appear in PCB factories. In front of him. However, with the development of the Internet, environmental protection and environmental informatization have also been developed by leaps and bounds. Environmental information data centers and green electronic procurement are gradually being applied to the actual production and operation fields.
The manufacturing process of PCB circuit boards will be different for different types of products, and can be roughly divided into six stages: board making, assembly, drilling, cutting, printing and testing. Due to the continuous miniaturization and refinement of electronic products, most of the current circuit boards are attached with etching resists (laminated or coated). After exposure and development, the circuit boards are made by etching.

PCB circuit board processing can be divided into two categories, the following is an introduction to the two categories of knowledge about circuit board processing:

The subtraction method is to use chemicals or machinery to remove the unnecessary parts of the blank circuit board, and the remaining space is the required circuit. For example, the inner layer of the multilayer board and part of the single-sided board, the simple process is as follows:

Material--grinding board--screen printing ink/film---exposure/development---etching a---fading film---semi-finished product

is generally used for negative film production, and acid etching is mostly used, because the ink/dry film is not alkali resistant, and now more use of hydrochloric acid copper chloride etching solution

The additive method is now commonly used to cover a substrate with a thin copper plated with a photoresist, and then develop after exposure to ultraviolet light to expose the necessary places, and then use electroplating to increase the thickness of the official circuit on the circuit board to The required specifications are plated with a layer of anti-etching resist-metal thin tin, and finally the photoresist is removed, and then the copper foil layer under the photoresist is etched away. iPCB is happy to be your business partner.
