Automotive PCB stands for printed circuit board, also known as printed wiring board. Here is an introduction about the types of automotive PCBs: Flexible PCB: These boards are made with flexible plastic substrates, composed of PEEK, polyamide or transparent polyester film. These boards can be twisted and bent. Used in automotive curves and corners. Rigid PCB: Rigid boards are made of FR4. These boards are inflexible. Typically used in displays and rearview camera screens. Rigid-flex PCB: These boards combine features of both rigid and flexible circuit boards. Implemented in lighting systems. HDI-PCB: These boards feature higher wiring density per unit area, finer lines and spaces, and higher pad connection density. HDI boards can accommodate more components and play an important role in miniaturization. These boards are widely used in infotainment systems. LED-PCB: LED substrates are made with aluminum base due to heat dissipation requirements. Can be found in automotive indicators, headlights and brake lights.

What should be noted when changing lanes on the road?

Only change to an adjacent lane at a time. If you need to change to a lane beyond the adjacent one, first change to the adjacent lane, drive for a while, and then change to another lane; 4. In sections where the lane dividing line is solid or dashed, vehicles on the side of the solid line are strictly prohibited from changing lanes; 5.
