Changes in the Channel Pattern of printed circuit board assembly Products
The explosion-proof ultrasonic power generator product has high explosion-proof performance, and the channel pattern of printed circuit board assembly has changed. Our company can provide explosion-proof solutions for products according to the actual needs of customers. It is a multifunctional ultrasonic power generator.
The shell must be grounded with a grounding resistance of ≤ 4 Ω. All products must pass explosion-proof certification and must pass explosion-proof certification.

This product has been released by a national authoritative organization and complies with the EN1 Ministry of Science and Technology Explosion Safety Technical Specification (GB30449). Suitable for various explosion-proof locations.
★ Explosion proof structure design, with a smooth and flat surface, and a horizontal grating design that is not obstructed by obstacles during installation.
★ electrostatic induction, together with anti-static wrist strap, electrostatic induction and shock absorption device, safety wrist strap shall be used when installing indoor anti-static wrist strap.
★ Electrostatic bracelets should be securely welded, transportation belts or batteries should use 3m anti-static leather, and static bracelets should be hated.
★ Use black rubber tape that comes into contact with the screw connection, suitable for new products with foot lengths of 50mm, 08mm, or greater.
★ Metal components should be optional and the weld seam should not exceed 300mm. Otherwise, they should be converted into insulators during use to protect the components from potential short circuit risks.
The connection of screws, washers, and other accessories should be kept between 05mm and 2mm to avoid loosening. If it is necessary to connect, a dedicated person should be responsible for the construction and should not exceed the specifications.
After the screw position, the screw should be tightened, and the panel of the nut should have detachable bolts. The bolts should be arranged without loosening.
In the D-type installation screw hole, both ends of the screw cannot be punched. The two screws around the K-type installation screw holes should be polished with paint. This time, at the four corners of the long plate shell, tighten the two bridging screws on one side respectively, so that the nut holes should be tightened.
The semi-circular washer between D-type installation screws has a foot spacing of less than 1mm. The triangular welding point spacing of D-type installation screws shall not exceed 10mm. In the edge area of the circuit board, in order to avoid touching the edge of the circuit board. The frame of the D-type mounting screw extends outward. The circular arc part of the D-type installation screw should not be offset.
The circuit boards used in the SMT processing process on the market are generally surface assembly technology. Nowadays, the technology is very developed. The circuit boards used in the SMT chip mounting process are generally surface assembly technology, and the circuit boards processed using SMT chips are usually of stable quality. The PCB welding process is also relatively complex, and the more layers of the circuit board, the higher the processing cost, and the circuit board.
There are also many materials to be inspected, and there are various types of copper foil etching processes and complex processing processes, all of which require the production of a testing needle bed. The specific production and testing processes mainly include the following and testing product inspection workers.
