During the entire process of PCBA production, manufacturing, and processing, defective PCBA boards will frequently appear due to improper operation by a small number of workers or the quality of raw materials. In addition, defective PCBA boards must be inspected and repaired. So, in the rapidly developing metropolis of Shenzhen's electronic industry chain, how is the process of PCBA maintenance, production, and manufacturing carried out?

The process of PCBA maintenance and manufacturing can generally be divided into several stages, each of which is indispensable: visual inspection of PCBA → accurate measurement of all POWER → poor power supply detection → maintenance based on safety risks → self correction and self inspection after maintenance → testing fixture inspection → visual inspection and full inspection. The following provides a detailed explanation of these 7 processes.

1. Visually inspect PCBA. This step is mainly to facilitate the inspection of whether the PCBA produced and manufactured has obvious poor appearance. For example, motherboard short circuit, empty soldering, lack of prefabricated components, reverse polarity of electronic devices, and damage to wrong electronic devices. For production plants with high reliability, every step seems crucial.

2. Accurately measure all POWER. This is mainly for the purpose of accurately measuring whether there is a common ground short circuit fault in the switch power supply circuit. In many cases, it is due to a small problem that important latest projects fail. We have professional staff to inspect every PCBA produced and manufactured, and deliver high-quality products to you.

3. Poor power detection. After inserting the wire, use a testing fixture to check whether the wire is of high quality. Every prefabricated component is very important.

4. Repair according to safety risks. Since the inferior object has been searched for a long time, it is also in the condition of rushing to repair it.

5. Self correction and self inspection after repair. After repair, it is necessary to conduct self correction and self inspection on the repaired part Important inspection: Common faults include short circuit, empty tin wire, bead, solder slag, and welding appearance.

6. Testing fixture inspection. Use testing fixtures to check if the PCBA is repaired properly.

7. Visual inspection and full inspection. Conducting a full inspection of the repaired products and repairing inferior PCBA boards can reduce damage to the wooden boards and lower production costs for the manufacturing plant.
