PCBA board is the core of electronic products, just like the position of the Chinese army in the battle of the three armies. Product reliability, ease of use and stability are closely related to the quality of PCBA. Therefore, in the process of purchasing PCBA, we need to urgently pay attention to PCBA quality control points, and use a professional eye to examine whether each PCBA board meets the application requirements of electronic products. The following are the points to be noted by Changkeshun Technology for the assembly and processing of electronic finished products:
1. The reliability of PCBA components welding
The reliability of PCBA board and component soldering directly determines the performance of electronic products during use. With the in-depth use of products, the circuit board suffers from oxidation, heat radiation, drop, and overload use, which will cause the factory to be OK The PCBA board started to show welding problems, and the product failed. In addition, in PCBA processing, whether to use brand original and genuine components is also crucial to the quality of electronic products. Many second-hand or counterfeit components will explode in failure during long-term use. The same is true for PCB circuit boards. According to the application environment of the product, to prevent the deformation of the PCB and the influence of heat, these factors need to be taken into consideration when purchasing the PCBA and undergo rigorous testing.
2. PCBA aging test performance report
When purchasing PCBAs in large quantities, strict aging tests are required. Give the PCBA board extremely strict conditions of use, and test its stability and reliability. Many companies omit this step in order to save costs. As a result, batch products are defective in the hands of customers, causing greater losses. Therefore, when purchasing PCBA, it is recommended to put forward aging test requirements for batch products, configure aging test fixtures and require suppliers to provide aging test performance reports.
3. PCBA assembly process management
The assembly process of PCBA board, housing, and packaging is also more important. Improper operation of many assembly processes will also cause damage to the soldered components on the PCBA board that has been tested and cause defects after assembly. The PCBA supplier’s assembly process needs to have strict operating instructions and supervise the workers to follow the procedures.
4. Cleanliness of PCBA board surface
The cleanliness of the PCBA board surface is very important. A lot of hand-soldering tin slag, flux, etc., if left on the PCBA surface, will cause unpredictable risks in the use of electronic products in the future. Therefore, PCBA manufacturers must be required to perform professional ultrasonic cleaning on all batches of PCBA panels and prevent fingers from contaminating the panels.
5. Purchase after-sales service capabilities of PCBA board suppliers
When purchasing PCBA, evaluation of the supplier’s after-sales service capability is also very important. A wise man must make a mistake when he thinks about it. With the deepening of mass manufacturing, undesirable phenomena will definitely occur. At this time, the ability of PCBA manufacturers to respond quickly and cooperate in a timely manner is particularly important.
