PCBA is the core of electronic products,just like the position of the chinese army when the three armies face each oter. The quality of PCBA is closely connect to the product reliability,usability and stability. So we need to pay close attention to the pcba quality control points when purchase that,need to use a professional eye to check whether each pcba board meets the application requirements of electronic products.
1. The reliability of PCBA components solder
The reliability of PCB bare board with electronic components welding directly determines electronic products performance during use.With the deep use of products, the boards may suffer from harsh conditions,such as oxidation,heat radiation,drop and overload,these will cause the the board begin have welding problems which cause the prodcts useless.On the other side. It’s very important to the electronic produts quality see if the pcba board use original electronic components during the process. The long-term use of second hand and counterfeit components will break out of failure.The pcb bare board aslo the same.According to the application environment of the product,to prevent the pcb board from deformation and the influence of heat,these factors need to take into consideration when pruchase pcba and take rigorous test.
2. The performance report of PCBA aging test
Massive procurement of PCBA requires strict aging tests.Give PCBA board extremely strict conditions of use and test it’s staliblity and reliability.Many companies omit this step in order to save costs.It turns out many products are bad in customer’s hands and cause greater losses. Therefore,when purchase PCBA,it’s recommended that ask the supplier provide againg test for massive procurement with againg test fixtures,also ask they provide the aing test performance reports.
3. The management of PCBA assembly process
It’s very important for the assembly process of pcba board with the product case and packaging. It also can damange the electronic components on the OK pcba board if many processes are not properly handled,this resulting in poor assembly.The pcba supplier assembly process requires rigorous operation instructions and supervised the workers to complete the process.
4. PCBA board cleanliness
The cleanliness of the pcba board surface is very important. Many hand soldered tin dross and solder fluxes left on the surface of the PCBA,will cause unpredictable bad risk when use of the electronic products.Therefore,PCBA manufacturers must be required to perform professional ultrasonic cleaning of all batch pcba boards and prevent fingers from contaminationg the board surface.
5. Procurement of PCBA suppliers’ after-sales service capabilities
When purchasing PCBA, it is also important to evaluate the after-sales service capabilities of suppliers. The wise are in for a moment. With the in-depth development of mass production, it is bound to produce undesirable phenomena. At this time, the ability of PCBA manufacturers to respond quickly and solve in a timely manner is particularly important.
6. when the purchase of PCBA manufacturers give a little more profit
With the development of the circuit board and SMT processing industry, the price of PCBA is extremely transparent. As long as there is a slight comparison or accounting, the possibility of being slaughtered can be avoided. Profit is the biggest driving force for an enterprise’s customer service. With profit, it has the service and the highest standards of quality control. In view of this, in the process of purchasing PCBA, it is necessary to abandon the thinking that the price has been suspended, and give PCBA manufacturers appropriate profits, which will help the perfect manufacture of their products and maximize their self-interest. In this regard, companies in developed countries such as Japan have performed extremely well.
Procurement of PCBA is a matter that involves multiple aspects of technology, management, service, etc. It requires procurement personnel to examine from multiple angles, and lays a good foundation for PCBA manufacturing process of electronic products.
