PCBA is the core of electronic products, and the reliability, availability and stability of products are closely related to the quality of PCBA. Therefore, in the process of purchasing PCBA, PCBA customizers need to pay close attention to the quality control points of PCBA, and examine whether each PCBA board meets the application requirements of electronic products from a professional point of view.
The reliability of PCB component soldering directly determines the performance of electronic products in use. With the use of the product, the circuit board will have problems such as oxidation, heat radiation, drop, overload use, etc., which will cause the PCBA board to have welding problems, resulting in product failure. In addition, in PCBA processing, whether to use regular products and brand components is also very important to the quality of electronic products. Many used or counterfeit parts will crack and fail after prolonged use, the PCB is still look like the same. According to the application environment of the product, in order to prevent the deformation of the PCB and the influence of heat, all these factors need to be considered when purchasing the PCBA, and rigorous testing should be carried out.
When purchasing PCBA in large quantities, a strict aging test is required. Give the PCBA board more stringent conditions of use, and test its stability and reliability. In order to save costs, many companies skip this step, resulting in defects in the batch of products in the hands of customers, resulting in greater losses. Therefore, it is recommended that when purchasing PCBA, put forward aging test requirements for batch products, configure aging test fixtures, and require suppliers to provide aging test performance reports.
The assembly process of the PCBA board, housing and package is also important. Many improper operations in the assembly process can also cause damage to the soldered parts of the PCBA board that have passed the test, resulting in defects after assembly. The assembly process of PCBA suppliers needs to have strict operating instructions, and workers must complete the process under supervision.
It is important to clean the PCBA board. Many hand-soldered dross and fluxes, if left on the surface of the PCBA, pose unpredictable adverse risks to the future use of electronic products. Therefore, PCBA manufacturers need to be required to perform professional ultrasonic cleaning on all batches of PCBA boards to prevent finger contamination of the boards.
It is also important to evaluate the supplier's after-sales service capabilities when purchasing PCBAs. Smart people make mistakes. With the deepening of mass manufacturing, there will be some undesirable phenomena. At this time, the ability of PCBA manufacturers to respond quickly and cooperate in a timely manner is particularly important.
With the development of PCB and SMT processing industry, the price of PCBA is relatively transparent, so as long as a little comparison or calculation, you can avoid the possibility of being slaughtered. Profit is the driving force for a company to serve customers. With profits, it can provide services and higher standards of quality control. In view of this, in the process of acquiring PCBA, it is necessary for PCBA customizers to abandon the idea of always bargaining and give PCBA manufacturers appropriate profits, which will help them make good products and maximize their own interests.
PCBA procurement is a multi-link evaluation including technology, management, and service. PCBA customizers need procurement personnel to inspect from all angles to lay a solid foundation for the PCBA manufacturing process of electronic products.
