FC PCBA specializes in high-reliability automotive PCB assembly and is committed to supporting innovation in the automotive industry by incorporating advanced technologies into production to meet the extreme demands of the automotive environment: vibration, thermal stress, and stringent safety standards. Our goal is to meet the industry’s industry’s changing requirements and significantly contribute to the development of the future of automotive technology and sustainability.
Reliability is vital for printed circuit boards used in automobiles. They must withstand harsh environmental circumstances and vibrations without experiencing any performance setbacks. Before being considered, automotive PCBs must pass complex thermal cycle tests, thermal shock tests, and temperature and humidity tests.
Automotive printed circuit boards differ significantly from other printed circuit boards regarding heat resistance and service life. PCB makers must follow the ISO/TS 16949 standard, based on the ISO 9001 automotive standard.
FC PCBA considers all the required PCB standards to make your automotive PCB. Car charger circuit boards, car navigation circuit boards, car instrument circuit boards, and new energy car circuit boards are among the automotive PCB items.

PCBs interconnect and manage sensors and actuators for fuel injection, timing of ignition, emissions, and power delivery to improve engine performance and fuel efficiency while maintaining emission standards under strict regulations.
Airbags, anti-lock braking systems (ABS), electronic stability control (ESC), and other advanced driver assistance systems (ADAS) such as collision avoidance, lane departure warning, and adaptive cruise control are all based on highly reliable PCBs for stable function.
LED headlights, taillights, and interior lighting systems generally use PCBs with good heat-dissipation properties (e.g., aluminum substrates) to ensure long operating life and stability in hot environments.
In-car touchscreens, navigation, audio and video modules, Bluetooth, and Wi-Fi communication all rely on high-speed signal-handling specialized PCBs that provide a smooth user experience.
PCBs in electric cars (EVs) and hybrid vehicles find widespread application in battery management systems (BMS), power converters, inverters, and charging control modules. These types of applications require PCBs with high voltage/current carrying capacity and good heat management.
PCBs in automatic transmissions control shifting devices and optimize power output efficiency. They also form the hub of motor control units in electric vehicles.
From tire pressure monitoring systems (TPMS) to radar and ultrasonic sensors, PCBs enable real-time capture of various sensor data and communication between subsystems, providing rudimentary support for intelligent vehicle control.
Along with the development of circuit board manufacturing process and test technology, the reliability, stability, and safety of vehicles will also be improved. To meet the quality requirements of automotive electronic PCBs, automotive PCBs generally have to meet the following industry standards:
This standard defines the safety life cycle of automotive systems, covering the design, development, and validation of safety-critical electrical/electronic (E/E) systems. Functional safety testing is utilized to ensure that system designs eradicate failures that can lead to damage, including fault tolerance and system failure mode testing in automotive setups.
AEC-Q100 defines test requirements for automotive application integrated circuits (ICs). The tests are designed to enable the components to meet the rigorous durability requirements of automotive systems, particularly in severe environmental conditions such as temperature extremes, humidity, and mechanical stress.
A generic PCB design standard that influences testing by making the PCB layout electrically performant, thermally managed, and mechanically structurally sound.
This standard focuses on testing the electromagnetic compatibility of automotive PCBs so that they won't interfere with the normal operation of other electronic systems in the vehicle. Some of the key tests consist of electromagnetic interference (EMI) immunity and radiation performance.
Although this standard is a military standard, it is often used for testing automotive PCBs due to its harsh environmental conditions. It covers the various environmental factors that automotive systems must withstand.
This standard specifically addresses automotive semiconductors, specifying performance and reliability requirements for components used in automotive circuits (such as diodes, transistors, and sensors) to ensure they function properly in the automotive environment.
This directive restricts the use of hazardous substances in electronic components. PCBs for automotive applications must comply with RoHS to reduce hazards to the environment and human health. This includes prohibitions on materials such as lead (Pb), mercury (Hg), and cadmium (Cd).
This international standard specifies the quality management system (QMS) for quality development of automotive systems throughout the entire supply chain. It covers documentation, management responsibility, process control, evaluation, and continual improvement.
Different automakers may develop their own test standards for PCBs. They are typically based on specific vehicle applications, such as infotainment, powertrain control, and advanced driver assistance systems (ADAS), and cover wide ranges of performance requirements.
For enhancing overall vehicle reliability, stability, and safety, FC strictly follows quality control in designing, producing, and testing automotive PCBs.
The differences between automotive PCB boards and standard PCB boards are as given below:
It is a standard rigid PCB made of FR-4 glass epoxy. For thermal reliability, it includes more significant Tg variations, such as FR-4 High Temp. It contains no flame-retardant or halogen ingredients. It offers thermal management metal core boards.
It is lighter compared to ordinary printed circuit boards and wire harnesses. Flexible printed circuit boards significantly reduce the labor required to manufacture traditional automotive wiring harnesses. In addition, flex-printed circuit boards are ideally suited to the challenging conditions inside automobiles due to their inherent vibration resistance.
A hybrid of rigid and flexible PCBs, rigid-flex boards combine durability with design flexibility. They are ideal for compact automotive systems where space is limited but reliability is critical.
It is metal core PCBs or insulated metal substrate (IMS). It comes with a metal baseplate, often aluminum– or copper-based, is designed for applications requiring excellent heat dissipation and EMI shielding.
High-Density Interconnect Printed Circuit Boards (HDI PCBs) are high-tech printed circuit boards with ultra-high data transfer speeds and very low latency for handling high-speed data and complex control tasks. High-density interconnect printed circuit boards are typically used for advanced assisted driving systems, automatic braking systems, and in-car entertainment systems.
High-frequency PCBs are commonly used in automotive collision avoidance or predictive emergency braking systems that rely on P
