PCB power supply

The outstanding requirement of PCB power supply is high reliability and high symmetry of coating.  PCB power supply adopts brand-new power supply operation and monitoring circuit, with large redundancy, which can ensure the reliable operation of power supply.  The symmetry degree mainly depends on the output waveform of the power supply, and the power supply has the effect of reducing the working time, saving raw materials, reducing costs and so on.  

1, reduce the porosity, the formation rate of crystal nucleus is greater than the growth rate, to promote the refinement of crystal nucleus.  

2, improve the binding force, make the passivation film breakdown, is conducive to the solid combination between the matrix and the coating.  

3,  To improve coverage and dispersion ability, high negative potential cathode make the position of ordinary plating passivation can also deposit, salient parts due to the deposition of slow form complex components ion "burned" resulted from the excessive consumption of "dendritic" deposit defects, for a given feature coating (such as color, no pore) thickness can be reduced to the original 1/3 ~ 1/2, save raw material  Material.  

4, reduce the internal stress of the coating, improve lattice defects, impurities, cavities, rumen, etc., easy to get crack-free coating, reduce additives.  

5. It is beneficial to obtain stable alloy coating.  

6, improve the dissolution of the anode, no anode activator.  

7, improve the mechanical and physical properties of the coating, such as improving the density and reducing the surface resistance and body resistance, improve toughness, wear resistance, corrosion resistance and can control the hardness of the coating.  

Traditional electroplating has no effect on inhibiting side effects, improving current distribution, regulating liquid mass transfer process and controlling crystal orientation, so the research on complexing agents and additives has become the main direction of electroplating process research.  Nano - switching power supply solves the defect of traditional rectifier.  

8, improve product yield, product quality.  

PCB power supply is based on imported IGBT as the main power device, and the transformer core is based on ultra-crystal (also known as nanocrystalline) soft magnetic alloy material. The main control system adopts multi-loop control technology and adopts anti-salt spray acidification measures in structure.  The power supply has reasonable structure and high reliability.  The power supply with its small volume, light weight, high efficiency, high reliability and superior performance become the replacement of silicon controlled power supply products.
