- AEC-Q104: Defines failure testing and qualification standards for discrete optoelectronic semiconductors.
- AEC-Q200: Defines failure testing and qualification standards for passive components.
- IPC-6011: Describes PCB performance standards and specifications.
Industry Standards
ISO 9001 (Quality Management) and IATF 16949 (for the automotive industry) are some of the standards followed in the automotive industry. Automotive circuit boards always need to be inspected according to IPC-A-600 Level 3 standards. These standards ensure a quality management system and superior operation, thereby enhancing the reliability of automotive PCBs under all operating conditions. During the manufacturing process, quality control is as important as testing to ensure that all automotive circuit boards meet the highest reliability and performance standards.
Our Automotive PCB Testing Process
Geyuan Electronics supports major OEMs, We applies a rigorous testing and quality management system to detect defects, verify mechanical integrity, and confirm electrical functionality under the demanding conditions used in automotive applications. This includes:
Cross-Section
Cross-section analysis involves cutting a sample PCB and polishing the cut area to examine internal layer alignment, via walls, plating quality,and solder joints under a microscope. This allows us to measure plating thickness, detect voids, and evaluate copper distribution. Analyses are performed according to IPC-TM-650 acceptance criteria.
X-ray Analysis
X-ray inspection uses high-resolution imaging to visualize hidden solder joints, internal vias, and component placements. This method identifies cold solder joints, insufficient plating, and internal fractures without damaging the board, following IPC-A-610 Class 2 & 3 workmanship standards.
Vibration
Vibration testing mounts PCBs onto fixtures connected to multi-axis shakers, simulating real-world automotive vibration profiles.Testing follows IPC-6012DA criteria and SAE J1211 vibration standards.
Mechanical Stress Testing
Mechanical stress testing includes tensile and compressive force application to validate the strength of vias, solder joints, and component placements. Testing validates conformance to AEC-Q200 mechanical durability benchmarks for high-vibration and shock environments.
Temperature and Humidity Testing
Through simulated environmental conditions, tests demonstrate that the PCB can withstand the harsh effects of humidity and corrosive agents found in the automotive interior environment.
Extensive Electrical Testing
Continuous testing is conducted at every step of the manufacturing process, including AOI testing, BGA X-ray testing, flying probe testing, and other electrical tests.
Geyuan Electronics Ensures Long-Term Supply of Automotive PCB
For automotive PCB manufacturing, Geyuan Electronics doesn’t recommend materials solely based on their names. We comprehensively consider factors such as layer stack-up, copper foil usage, heat load, dielectric requirements, soldering processes, and the end-use environment before recommending the most suitable materials. Furthermore, our cooperation with suppliers relies on open and transparent communication to ensure material supply. This helps anticipate potential supply issues, allowing for proactive measures such as finding alternatives or stockpiling critical components. When designing automotive PCBs, we consider in advance whether the board can accommodate alternative or compatible components. This ensures supply chain continuity even as technology evolves.
Case Study: LiDAR PCBs for Automotive Collision Avoidance Systems
We manufacture PCBs for LiDAR sensors that measure distances between vehicles and various objects, generating 3D images of the detected objects. These boards must possess extremely high reliability. Therefore, we provide design reviews and high-level manufacturing testing methodologies to ensure you receive high-performance boards. Geyuan Electronics is currently collaborating with a leading global 3D sensing company to help them develop an AI-driven LiDAR platform. We provided them with high-speed, multilayer PCBs that had to meet stringent requirements, such as vibration resistance and thermal cycling without performance degradation. Furthermore, we solved the wire bond alloying problem that other PCB manufacturers could not address.
FAQ
Automotive PCB manufacturing refers to the process of producing printed circuit boards (PCBs) for vehicle electronic systems. These boards are used in lighting, power control, sensors, battery systems, control modules, radar auxiliary circuits, and other automotive electronic products.
Automotive PCBs are typically rated for temperatures from -40°C to 125°C. Boards mounted near the engine sometimes need to withstand peak temperatures up to 150°C.
IATF 16949 is a quality management system standard that covers how manufacturers operate their production processes; while AEC-Q100 is a component-level stress testing certification that confirms the ability of individual components to withstand automotive-grade environmental conditions.
ISO 26262 applies to safety-critical systems, requiring documented risk analysis, design verification, and testing throughout the development process. This means that circuit boards used in systems like ABS or airbags require a more rigorous design and verification process than non-safety-critical boards.
Geyuan Electronics specializes in manufacturing HDI boards for ADAS (Advanced Driver Assistance Systems) and radar modules to achieve controlled impedance. Our engineering team rigorously verifies impedance during the design and engineering phases to ensure stable and reliable performance in high-speed applications.
Manufacturers supplying PCBs to automotive OEMs typically need IATF 16949 certification. This quality management system certification is almost mandatory. Without it, most automakers will not accept your company as a supplier. Furthermore, your PCB manufacturing process should comply with IPC-6012 Level 3 or IPC-6012DA (Automotive Add-on) specifications.
Most automotive ECUs and body control modules use 4-8 layer circuit boards. Complex ADAS controllers and electric vehicle power electronics may require 10-16 layers or more. As systems integrate more functions, increasing the number of layers is a growing trend. HDI technology using microvias allows for higher density without adding excessive layers, which is particularly important for compact sensor modules and camera systems.
This is precisely Geyuan Electronics' expertise. We focus on pre-certification prototyping, helping engineers validate their design intent before applying for full automotive certification. Our goal is to provide you with clean, accurate test boards quickly.
For high-current applications such as power distribution units and motor controllers, Geyuan Electronics offers thick copper PCBs with copper weights up to 20 ounces. We carefully design trace widths and thermal vias to meet expected current loads and effectively dissipate heat. All designs comply with IPC-2152 current carrying capacity standards and AEC-Q200 thermal management requirements.
