四、Inspect supplier’s quality control process
1. Quality inspection methods: Suppliers should have complete testing facilities and methods, such as X-ray inspection, automatic optical inspection (AOI), etc.
2. Traceability system: High-quality PCB suppliers will have a complete product traceability system that can track the production and inspection history of each PCB.
3. Customer feedback: Understanding the supplier’s existing customer feedback, especially automotive-related customer feedback, can provide important reference information.
When choosing an automotive electronics PCB board supplier, you need to comprehensively consider many factors. Through the above analysis, you can initially screen out suppliers with industry experience, strong technical capabilities, reliable quality and considerate service, taking into account the sustainability of long-term cooperation. , it is recommended to establish long-term and stable cooperative relationships with suppliers to jointly cope with possible future challenges in the automotive industry.
Automotive electronic PCB board customization requirements
With the rapid development of automotive electronics technology, PCB is increasingly used
in automotive electronics. From engine control systems to airbag systems to advanced driving assistance systems, the quality and performance of PCB boards directly affect the safety of the car. Strict standards and requirements must be followed when customizing automotive electronic PCB boards. So, let’s take a look. Understand the customization requirements for automotive electronic PCB boards.
1. Material selection
The material selection of automotive PCB boards is very critical. It can work stably under extreme environmental conditions. High temperature, low temperature, humidity, vibration and pollution are all factors that must be considered. Commonly used PCB board materials include FR-4, PTFE (polymer) Tetrafluoroethylene) and metal-based materials, etc., can provide sufficient mechanical strength and thermal stability.
2. Design specifications
When customizing automotive electronic PCB boards, design specifications are very important. They usually cover the thickness of the board, the number of layers, the thickness of the copper foil, the size and spacing of the pads, line width/line spacing, etc. For automotive PCBs, special attention is also required. The design of its power layer ensures the stability and uniform distribution of current.
3. Thermal management
Due to the high temperature characteristics of the automotive environment, thermal management has become an important consideration when designing automotive electronic PCB boards. Reasonable thermal design can not only ensure the stable operation of electronic components, but also extend the service life of the product. Commonly used thermal management techniques include using substrate materials with good thermal conductivity, designing efficient heat conduction paths, and adding radiators or heat pipes.
4. Electrical performance
Automobile PCB boards must have excellent electrical properties, including sufficient dielectric strength, good insulation resistance and anti-electromagnetic interference (EMI) capabilities, especially in the safety and control systems of automobiles. Any form of electrical failure may cause serious s consequence.
5. Testing and certification
All customized automotive electronic PCB boards need to go through a rigorous testing and certification process to ensure their performance and safety in actual applications. These tests may include electrical testing, environmental suitability testing, functional verification, etc., and must also comply with IATF 16949, ISO 9001 and other international quality management system standards.
6. Reliability and durability
The reliability and durability of automobile PCB boards are key indicators to measure their performance. High-quality materials and advanced processes must be used in the design and manufacturing process to ensure that the PCB board can continue to work throughout the entire life cycle of the car, especially during When faced with harsh road and weather conditions.
7. Environmental friendliness
As the world pays more attention to environmental protection, the automotive industry is also promoting green manufacturing and sustainable development. The production of automotive electronic PCB boards should also take environmental factors into consideration, such as using lead-free solder and materials that comply with environmental standards such as RoHS and REACH.
Customization of automotive electronic PCB boards is a complex and rigorous process involving many aspects of technology and standards, from material selection to design, from thermal management to electrical performance, to testing certification and environmental friendliness, every link must be precise controls to ensure final product performance and safety. With the advancement of technology and market demand, the standards and requirements for automotive PCB customization will continue to evolve to adapt to future changes in the automotive industry.
