I believe many customers of Shenzhen PCB factories will face the problem of "how to maintain PCB boards" and do not know what to do to prolong the lifespan of circuit boards. Now, the Shenzhen PCB factory will teach you how to maintain PCB circuit boards.
1. Observe whether there are electronic components that have passed through high temperature marks on the circuit boards produced by the Shenzhen PCB factory, and whether there are bulges and leaks in the electrolytic capacitors. If there are any of the above phenomena, they should be replaced.
2. Regularly perform dust removal and cleaning on PCB circuit boards every season, using a dedicated cleaning solution and drying with a hair dryer.
3. If the capacity of the electrolytic capacitor on the PCB circuit board is found to be less than 20% of the rated capacity, it should be replaced; The service life of a general electrolytic capacitor is about 10 years and should be replaced to ensure the working performance of the PCB circuit board.
4. For high-power devices coated with thermal conductive silicone grease, it is necessary to check whether there are dry solids in the thermal conductive silicone grease; For dry solids, the dried solid cooling silicone grease should be removed and coated with new thermal conductive silicone grease to prevent the cooling and burning of PCB circuit boards from causing high-power equipment to malfunction.
5. PCB circuit boards should be properly placed, and the surfaces between boards should not come into direct contact. Once scratches or discoloration are found, they should be replaced immediately.
