What are the main points of making high-quality switching power supplies

　　The switching power supply market is mixed, and the price of the power supply with the same parameter can vary several times from low to high. In this mixed power supply market, it is necessary to be a high-quality switching power supply manufacturer. As a well-known manufacturer of high-quality switching power supplies in the industry, Shun’an Power Supply will explain to you how a high-quality switching power supply is produced.

　　We are divided into 4 main points: 1 circuit design 2 material selection 3 production process 4 inspection and delivery, each step is particularly important.

　　The first step is switching power supply circuit design and component layout. Circuit design Layout is the step of switching power supply production. The source of high-quality switching power supply requires a good circuit, and the layout of components is designed to arrange product grades and material requirements. Each switching power supply of Shun'an Power adopts sophisticated circuit design, and all products can pass CE, EMC, ROHS and other tests. The physical design of the pcb board is a link. If the design method is improper, the PCB may radiate too much electromagnetic interference and cause the power supply to work unstable.

　　The second is the selection of materials. The switching power supply produced with good components has the following characteristics: long life, low interference, stable quality, not easy to malfunction, and low repair rate. Most of the components used by Shun'an Power are imported materials. Cooperative suppliers include first-line component manufacturers such as ON, Fairchild, NXP, Ruby, Black King Kong and ST. From the source, the hidden dangers have been eliminated, thus achieving the title of high-quality switching power supply manufacturer in the true sense.

　　The third is the production process. The switching power supplies produced by Shun'an Power Supply are all produced by AI plug-in machine plug-ins, through wave soldering and reflow soldering. In the true sense, it is a manufacturer that has achieved high efficiency, high quality and exquisite craftsmanship. What’s incomparable with ordinary small factories is that most of the small factories will not use such superb craftsmanship to produce, and most of them are still in the manual production stage, so the failure rate of manual plug-ins will be higher than the failure rate of machine plug-ins. Much, this is one of the high-quality characteristics of Shun'an Power.

　　The fourth point is the important and latter point, which is the next step before leaving the factory: inspection and packaging. Each switching power supply of Shun'an Power has passed three test systems, and the test is bare board test. After the plug-in is completed, it is tested with semi-finished products. After being assembled into a finished product, it undergoes 4 hours of full load aging, and then a test before leaving the factory after the aging is completed. Then pack and ship.
