FPC flexible circuit boards are widely used in smart phones due to their high wiring density, light weight, thin thickness, and good flexibility. The FPC flexible circuit boards in smart phones are mainly used for the connection of parts and the motherboard, like Display modules, fingerprint modules, camera modules, antennas, vibrators, etc., with the continuous [...]
If the circuit board needs to be printed on both sides (side1, side2 or side A, side B) SMT, which side should be printed first? How is the first side to be played? What is the decision point? Editor: This problem is a bit more complicated. Generally speaking, at the beginning of the product design, [...]
Silicone oil type release film is very common in the production process of circuit boards and electronic and precision electronic components. The surface of the film is coated with a layer of silicone oil type release agent to reduce adhesion and achieve the release effect . It can be divided into single-sided release film and [...]
What should I do if I encounter a short circuit on the PCB circuit board? Today, the smt processing plant will explain to you some common problems in detail. 1. If it is manual soldering, develop a good habit. First, check the PCB board visually before soldering, and use a multimeter to check whether the [...]

Stainless steel precision casting or investment casting, silica sol process. It is a casting process with little or no cutting, and an excellent process technology in the [...]
Industrial aluminum coil oxidation technology and sealing technology are relatively common in the surface treatment of aluminum processing. The sealing and oxidation process design of industrial aluminum companies can continuously enhance their appearance corrosion resistance. Industrial aluminum in many countries At the time of sampling, most of our work comes out through inspection results because [...]
1. Features of casting inspection Castings are now widely used in aviation and aerospace, including aluminum alloys, magnesium alloy titanium alloys and high-temperature alloys. Compared with casting and blank processing to form workpieces, castings have low cost and can form very complex shapes, which is difficult for processing technology. Most of the castings have defects, [...]
