The production and manufacturing process of Small home pcba maintenance can generally be divided into several stages.

　　1. Visual inspection of Small home pcba. This step is mainly to check whether the manufactured PCBA has obvious poor appearance. For a small home pcba factory with high credibility, every step seems to be critical.

　　2. Accurately measure all POWER. This is mainly to facilitate accurate measurement of whether a switching power supply circuit has a common fault such as a short-circuit fault to ground.

　　3. The power supply detection is poor. After plugging in, use a test fixture to check whether the plug-in is of high quality. Every prefabricated component is very important.

　　4. Small home pcba factories are recommended to carry out maintenance according to safety risks. Since the poor objects have been searched for a long time, they are also under the condition of repairing.

　　5. Self-correction and self-inspection after maintenance of Small home pcba. After maintenance, be sure to conduct self-correction and self-examination on the maintenance part. Important inspection: short-circuit faults, common faults, empty tin beads, tin slag and welding appearance.

　　6. Test fixture inspection. Use the test fixture to check whether the maintenance of the Small home pcba is OK.

　　7. Visual inspection of Small home pcba. A full inspection of the repaired products, based on the repair of the poor PCBA board, can reduce the damage of the wood board and reduce the production cost of the manufacturer.
