Double-Sided PCBs
These boards have conductive layers on both sides. They support more advanced circuits and are used in dashboards or infotainment systems. They work better than single-sided ones.
Multilayer PCBs
Multilayer PCBs stack several conductive layers together. They suit advanced systems like navigation tools or safety sensors. These handle fast signals and stop signal interference.
Flexible PCBs
Flexible PCBs bend to fit tight spaces easily. They're great for areas like inside doors or under dashboards. Their flexibility makes them durable against vibrations.
Rigid-Flex PCBs
These mix rigid and flexible layers in one board. This makes them useful for complex systems like cameras or driver-assistance tools.

Choose a PCB based on your car's needs, circuit complexity, space available, and conditions it will face.

Common Wire-to-Board Connector Types

Wire-to-board connectors link cables to PCBs securely for smooth power or data flow. Here are common connector types found in cars:

Pin Headers
Pin headers use rows of pins to connect cables to boards simply. They're often seen in basic systems like power units because they're easy to install and affordable.
IDC Connectors
IDC (Insulation Displacement Connectors) attach flat cables without removing wire insulation first, saving time in small spaces.
Crimp Connectors
Crimp connectors secure wires with crimped ends tightly attached to terminals, ideal for high-vibration spots like engines.
HSD Connectors
High-Speed Data (HSD) connectors transfer data quickly for things like cameras or USB ports while staying locked securely during use.
PCB-Mounted Connectors
These attach directly onto the PCB itself, cutting down extra wiring needs while saving space in compact setups.
Terminal Blocks
Terminal blocks make connecting/disconnecting wires easy when frequent maintenance is needed later on.

Pick connectors based on what they’ll do, speed needed, and where they'll be placed in the car system! Always go for quality options that last longer!

Tips for Picking Car Electronics Parts
