Anti Interference Multilayer Automotive PCBA RF PCB Manufacturing
High Performance Automotive PCBA For Advanced Driver Assistance Systems
♦ What's Automotive PCBA?
Automotive PCBA, is the core of automotive electronic systems.It fixes the electronic components on the PCB to form a complete circuit, which is used in various systems of the car.
♦ Features of Automotive PCBA:
- High reliability: Adapt to the harsh environment of automobiles, such as -40℃~125℃ temperature, vibration, humidity, etc., to ensure long-term stable operation.Like the engine control unit (ECU) PCBA, need to accurately control the engine fuel injection, ignition timing and other key parameters under complex working conditions.
- Strong anti-interference: it can resist the complex electromagnetic interference inside the car and ensure stable signal transmission.For example, in the intelligent driving system, PCBA should ensure that the signals between sensors, controllers, etc. are accurate.
- Miniaturisation and high performance: to meet the demand for miniaturisation and intelligence in automotive electronic systems, and at the same time, to have high computing power, high data processing speed and other performance, in order to support autonomous driving and other functions.
♦ Types of Automotive PCB Assemblies:
| Application | PCB Requirements | Examples |
|---|---|---|
| Engine Control Unit (ECU) | High-temperature resistance, EMI shielding | Fuel injection, ignition timing |
| Infotainment System | High-speed signal integrity, multilayer | Touchscreens, GPS, Bluetooth |
| ADAS (Radar/LiDAR) | RF/microwave PCBs, low-loss materials | Collision avoidance, adaptive cruise control |
| EV Battery Management (BMS) | High-current PCBs, thermal management | Cell balancing, charge monitoring |
| LED Lighting | Aluminum PCBs for heat dissipation | Headlights, interior lightin |
