1, råvaruberedning
Det första steget i PCB -kortproduktion är att förbereda råvaror . Detta inkluderar kopparfolie, glasfiberduk, epoxiharts, fenolharts osv.
2, tryckning
Printing is an important step in the production of PCB boards. Firstly, we need to etch the copper foil into the circuit pattern of the circuit board. Then, transfer this pattern onto the protective layer. This process requires precise control to ensure the clarity and integrity of the pattern. Finally, we use an exposure machine to expose the protective layer, curing the Uncured Harts för att bilda ett stabilt skyddsskikt .
3, skärning
After completing the printing, we need to cut the PCB board into the required size. This step is usually performed using a laser cutting machine. During the cutting process, attention should be paid to controlling the cutting speed and depth to prevent deformation or damage to the board. In addition, we also need to perform edge processing to ensure that the edges of the circuit board are flat and free of Burrs .
4, montering
After cutting, we need to install various components (such as chips, resistors, capacitors, etc.) onto the PCB board. During this process, we need to pay attention to keeping the circuit board clean and avoiding dust and impurities from affecting circuit performance. At the same time, we also need to use solder paste and solder wire for soldering to ensure the connectivity of the krets .
5, kvalitetsinspektion
Det sista steget är kvalitetsinspektion . Vi kommer att använda testutrustning för att utföra omfattande prestandatester på PCB -kort, inklusive elektrisk prestanda, värmeprestanda, etc . först efter att alla tester kan kan PCB -kortet komma in på marknaden .}
