When purchasing PCBA circuit boards, various possible factors should be included in the evaluation, and the supplier's technology, management, and service level should be comprehensively considered to ensure that the quality of the purchased product PCBA circuit boards is guaranteed, the benefits are maximized, and a good foundation is laid for the subsequent production of electronic products.
In the process of purchasing PCBA circuit boards, we need to pay close attention to the quality control points of PCBA circuit boards, and use a professional eye to examine whether each PCBA circuit board meets the application requirements of electronic products. The reliability, ease of use and stability of the product are closely related to the quality of the PCBA circuit board. Purchasing friends need to be cautious when choosing a PCBA circuit board processing manufacturer and processing. So, it is very important to choose a PCBA circuit board processing manufacturer with excellent quality?
Purchasing PCBA circuit boards is a multi-link evaluation that includes technology, management, and services. It requires purchasing personnel to examine from multiple perspectives to lay a good foundation for the PCBA circuit board manufacturing process of electronic products.
The SMT chip processing environment must be clean and tidy, and the welding surface must not have any contaminants. How do purchasing friends choose high-quality PCBA manufacturers? In addition to paying attention to whether you have professional equipment, you must also have standardized management and a strong sense of service. So, what do you need to see if the operating rules are standardized?
1. Whether the anti-static and dust-free control is strict in the production workshop. For example: no food, drinks and no smoking. Do not leave clutter and keep the workshop clean and tidy.
2. Whether the process control pays attention to details. For example: do not directly touch with hands, whether the operator wears gloves to take it/whether wears an anti-static wristband/whether the production line is connected to the ground wire, etc. Otherwise, welding defects caused by static electricity are likely to occur.
3. Simplify the operation steps of PCBA and components, in order to prevent occurrence. Gloves need to be changed frequently where they must be used because dirty gloves can cause contamination.
4. Do not use detergents containing silicone resin, you need to use detergents specially formulated for surface welding stains.
5. For sensitive components such as thermal/humidity/pressure sensitive, in order to avoid confusion with other components, they must be marked with appropriate signs. In addition, all operations, assembly and testing must be completed on a workbench that can control static electricity.
6. Regularly inspect workshops to ensure their working performance. Components such as EOS/ESD can pose various hazards due to improper grounding methods or oxides in the ground connection. Therefore, it is necessary to strengthen the protection of the third wire grounding terminal connector.
Many purchasing friends have no clue when choosing a PCBA circuit board processing manufacturer, and can only judge the quality of a manufacturer from the price. This is very one-sided, and it is difficult to choose a suitable PCBA circuit board processing manufacturer.
What should we pay attention to when choosing a PCBA circuit board processing manufacturer? Next, the technicians of Lianzhi Circuit will introduce to you what are the problems that need to be paid attention to when choosing a PCBA circuit board processing manufacturer?
1. The production of circuit boards requires very professional equipment and professional management processes. Such as automatic solder paste printing machine, SMT placement machine, multi-temperature zone reflow soldering, wave soldering, AOI detector, ICT online tester and other equipment. These are the basic equipment for production. Professional equipment is only one of the conditions for buyers to choose SMT processing manufacturers.
2. Need to have a strong sense of service. PCBA assembly provides processing services, which should be considered for customers, consider problems from the perspective of customers, and take the initiative to assume corresponding responsibilities when encountering problems. Solve problems for customers. Therefore, the strength of service awareness is very important for customers.
3. Years of industry experience. You can refer to the products they have produced before to comprehensively judge which field they belong to, and consider whether they are suitable in combination with your company's needs, because only the right ones are the best.
4. The price of conscience. Now the prices of products on the market are very transparent. Do not choose suppliers that do not match your needs in order to save money, resulting in unstable quality. We should choose manufacturers with higher cost performance according to the range we can afford.
