The materials used in the production of automotive circuit boards include FR-4, aluminum, and polyimide.
FR-4: The choice of FR-4 is due to its excellent electrical performance, mechanical stability, and low cost, making it the best choice for the automotive industry with low-cost and high-quality requirements.
Aluminum: Automotive headlights use aluminum substrates to meet high heat dissipation requirements.
Polyimide: When higher flexibility and heat resistance are necessary, it is best to use polyimide to ensure the reliability and functionality of PCBs under different automotive conditions.
