The 60W desktop power adapter manufacturer tells you that the power adapter is always visible around us, and it is also a must-have item in our lives, so don’t you know the production process of the power adapter? Let's follow the power adapter manufacturers to briefly understand the power adapter production process.

Analysis of the production process of the power adapter:
1. Prenatal preparation
The 60W desktop power adapter manufacturer tells you that in order to ensure the smooth progress of product manufacturing and to complete the manufacturing operations efficiently and with high quality, it is necessary to make pre-production preparations in strict accordance with the relevant technical documents in advance. The 60W desktop power adapter manufacturer tells you that it mainly includes: the preparation of components, raw materials, and related equipment required; design documents, process documents, test methods, manufacturing operation regulations and materials of related power adapters, etc.; some components need to be assembled in advance And performance inspection of related components.
2. Coil making
The 60W desktop power adapter manufacturer tells you that, rigorously speaking, coil preparation is also part of the pre-natal preparation, but magnetic components are very critical to the power adapter and directly affect the product performance. Therefore, this item is listed separately and the operator needs to have Qualification certificate for magnetic devices. Determine the winding and performance parameters before the coil is wound, determine the material list according to the standard of the magnetic device, select the enameled wire and the skeleton according to the performance parameters of the magnetic device winding, and cut the size of each winding wire. The 60W desktop power adapter manufacturer tells you to fix the skeleton on the winding machine and make the winding. Special attention should be paid to: the wound coil should be fastened and flat; the incoming wire is short and the outgoing wire is long; first primary, then secondary; The stage has two windings. When the number of coil turns is the same, they are wound at the same time, and when the number of coil turns is different, they are wound separately. Finally, twist the incoming and outgoing wires of each winding 3-5 turns to avoid loosening, and then remove the skeleton from the winding machine, arrange the enameled wire, scrape the wire, and tin it.
3. Welding and assembly of components
The 60W desktop power adapter manufacturer tells you that standard component welding is the basic guarantee of product quality. It stipulates that there is no missing soldering of the components, each solder joint is firm, the contact is good, and there is no welding error. In the welding process, we must determine the accuracy of the raw materials; the electric soldering iron should be fully preheated, holding the soldering iron in one hand, and the tweezers or wire in the other hand; the welding should be in order, such as from large to small, from left to right, etc.; All components need to be inspected to see if they are firm, the contact is good, there should be no offset, desoldering, and false soldering. The solder joints should be smooth, round, and there should be no burrs and other undesirable phenomena; also need to check whether there are any leaks. Soldering and short circuit of components due to solder flow; chips, capacitors, and resistors should be close to the surface of the substrate.
4. Cleaning
The 60W desktop power adapter manufacturer tells you that cleaning refers to cleaning the substrate with an ultrasonic cleaning machine to ensure that there is no excess solder paste or impurities in the product. It is advisable to clean it twice. During operation, ensure that the cleaning equipment is installed stably, pour water and plate-washing water respectively according to the standard process, and clean for 1 minute. After cleaning, dry it at room temperature or in a high-temperature drying oven to inspect the cleaned substrate to see if there is any false solder, false solder, empty solder, short circuit, etc.
5. test
The 60W desktop power adapter manufacturer tells you that any production process inspection is an indispensable process, and it is also the last quality guarantee before the product is shipped. The power adapter inspection mainly includes routine appearance inspection, performance test and high and low temperature test.
The routine test is to check the packaging and appearance of the power adapter. There should be no damage, scratches, dirt, pin skew, etc.; put the power adapter under a 1.5-10x microscope to ensure that the coating is free of skinning, blistering, and no leads. Fracture, rust; use vernier calipers to detect physical dimensions. According to the provisions of the customer agreement, check the input and output parameters, load transients, and input voltage transients to check whether the output meets the requirements.
The high temperature test is to place the power adapter in a high temperature drying oven for more than 2 hours, and then quickly take out the product for performance testing; the low temperature test is to place the power adapter in a low temperature storage box and freeze for more than 2 hours, and then quickly take out the product for performance testing.
6. Pouring glue
The 60W desktop power adapter manufacturer tells you that filling glue means slowly injecting the refrigerated glue into the body. The glue should not pass the components, and the surface should be smooth and flat. The glued products are placed in the tray in parallel and solidified for more than 48H at room temperature. After the colloid has completely solidified, the next step can be carried out. After the product is potted into a whole, the anti-vibration performance is improved and the product quality is guaranteed.
7. Encapsulation
The 60W desktop power adapter manufacturer tells you to use a parallel seam welder for the enclosure. First place the product base in the fixture of the parallel seam welder, and then take the cover plate and place it on the product base to confirm the direction of the cover plate. According to the size of the shell to be welded, enter the corresponding length and width of the shell and the height of the left and right electrodes on the welding parameter interface, and perform spot welding after setting all the parameters. After the spot welding is completed, check whether the cover and the base are Spot welding together, followed by seam welding. After the welding work is completed, the welding surface must be inspected under a microscope at 20-40 times. The welding should meet the following requirements: the welding surface is well welded, and there should be no bad phenomena such as pores, cracks, unsealing, deviation of the cover plate, etc.; the welding surface should be smooth, without unevenness, and wheel marks; the welding surface should not be overburned. Scratched.
8. Marking
The 60W desktop power adapter manufacturer tells you that marking is the last step before the product is shipped. The product is marked to make the product model and pin function easy to identify, and to avoid wrong connection and misuse.
The 60W desktop power adapter manufacturer tells you that on the basis of the above-mentioned process, it is necessary to set up different testing links after the key links to ensure the product quality of each process. Strict technological processes and production standards are what every employee needs to strictly abide by. It is also an important guarantee for product quality and a guarantee for corporate reputation.
