What is an automotive PCB?

As the name suggests, automotive PCBs are printed circuit boards designed for automotive applications. They are PCBs with higher standards than normal PCBs used in consumer electronics, such as better grade material, thicker copper plating thickness and solder mask thickness, tighter tolerances, etc.

These PCBs can withstand extreme temperatures and vibration while providing reliable electrical connections in automotive systems. In Viasion, we are adept at manufacturing different kinds of automotive circuit boards with highest quality.

    Types of Automotive PCB

    Specifically, automotive PCB has the following classifications.

    The Characteristics of Automotive PCB

    • Automotive PCBs must be able to withstand extreme temperatures and vibrations.
    • Automotive circuit boards must provide reliable electrical connections over long periods without any degradation in performance or reliability.
    • Automotive PCBs require high insulation levels, even when exposed to the elements such as moisture, dust, salt spray and other contaminants that may cause corrosion or damage to components and circuitry on the board itself.
    • Automotive circuit boards are required to have a shallow failure rate due to their critical function within vehicles, so they need different testing processes and quality control measures compared with regular consumer electronics products.
    • Automotive PCBs often feature surface-mount technology (SMT) components, allowing for smaller footprints than traditional through-hole mounting techniques used in other types of embedded systems design projects.
    • Automotive circuits typically use higher voltage ratings than traditional consumer electronics applications since they need more power delivered directly from the battery sources under the hood.
    • Automotive printed circuit boards also require specific safety certifications based on where they will be installed inside each vehicle model, which adds an extra layer of complexity to the material selection process during the design phase.

    Frequently Asked Questions

    Automotive PCBs are printed circuit boards specifically designed for automotive applications.

    An automotive circuit board is designed to meet the industry’s standards for high reliability, temperature tolerance and vibration resistance. At the same time, standard PCBs cannot withstand these automotive-specific conditions.

    Using an automotive PCB can bring the following benefits.
    1. Improved performance
    2. Enhanced reliability

    Since automotive PCBs are very reliable, we should be careful when choosing suppliers for your projects:
    1. Experience in the production of automotive standards;
    2. High quality and tight tolerance in board thickness, copper width, etc;
    3. Cost-competitive;
    4. Great customer service team.

    In general, the basic process of automotive circuit board design is as follows: diagram → PCB outline → PCB stackup → copper trace routing → optimization and checking → network and DRC check → generate PCB files.

    The following are the main steps of automotive circuit board manufacturing in a simplified way.
    Inner layer copper → Lamination → Sheet cutting → Drilling → Dry film and exposure → Copper etching → Copper Plating → Solder mask → Silkcreen printing → Surface Finishes → Profiling → E-testing → Quality Checking → Packaging

    Automotive PCB designers must follow the guidelines below to better design automotive circuit boards.
    1. Consider the design requirements of automotive systems, including temperature, vibration, automotive protocols, and automotive-grade components.
    2. Pay attention to the use of automotive-grade components, robust electrical schematics, advanced noise mitigation techniques, reliable soldering technology, and circuit simulation verification.
    3. Automotive PCB designers must ensure that their design meets EMI/EMC requirements, automotive safety regulations, and automotive component qualifications.

    Apart from the above benefits, we should consider the risks of using an automotive circuit board.
    1. Automotive PCBs are vulnerable to electrostatic discharge (ESD), which can cause permanent damage to the automotive PCB and its components, resulting in system failure or malfunction.
    2. Thermal runaway can cause the degradation of the automotive PCB’s components and result in system failure.
    3. Additionally, automotive circuit boards can be prone to corrosion if exposed to corrosive substances or moist environments.
