In the modern automotive industry, printed circuit boards (PCBs) play a crucial role. As the core component of electronic systems, automotive PCBs not only need to carry and connect various electronic components, but also need to maintain stable operation under extreme temperature, vibration, and humidity conditions. Therefore, ensuring the quality and reliability of automotive PCBs is crucial. This article will delve into the industry standards and key inspection elements that need to be met in the quality inspection of automotive PCB circuit boards.
Overview of Industry Standards
International Organization for Standardization (ISO) standards:
ISO 9001: Quality Management System Standard, ensuring that enterprises systematically manage their quality control processes.
ISO/TS 16949 (now replaced by IATF 16949): Specific quality management system requirements for the automotive industry, particularly for continuous improvement and defect prevention in the supply chain.
International Electrotechnical Commission (IEC) standards:
IEC 60068 series: Environmental testing standards, including temperature cycling, vibration, impact and other tests, to ensure the performance of PCBs in harsh environments.
IEC 61508: Functional safety standards, which require the development and operation of safety related electronic systems.
Society of Automotive Engineers (SAE) standard:
SAE J-STD-001: Welding standards for electronic product assembly to ensure welding quality and reliability.
SAE AS5553: Standard for preventing the use of counterfeit and substandard electronic parts.
Other professional standards:
IPC standards: such as IPC-A-600 (rigid printed board acceptance standard) IPC-A-610 (Acceptance Criteria for Electronic Components) provides detailed quality acceptance criteria for PCB manufacturing and assembly
