Top PCB Assembly Strategies for Autonomous Car


The use of printed circuit boards has evolved over the years. It is worth noting that PCBs have come to play an integral role in the automotive industry thanks to innovations in circuit board equipment. As people rely on technology, newer innovations are constantly being introduced. Innovations in PCB design for self-driving car electronics have changed the way manufacturers build driverless car.

What is an autonomous car?

Autonomous cars are also called self-driving cars, driverless cars, computer-driven cars, etc. As an automated vehicle, self-driving cars can sense their environment and navigate without the need for human operation. Autonomous cars use technologies such as radar, optical radar, GPS and computer vision to sense their environment.

PCB assembly strategy for self-driving cars

For automotive electronics PCB assembly, it is necessary to choose the right PCB materials and specific designs to meet the requirements set forth in the use standard to ensure that no problems occur in production. Therefore, the following basic strategies need to be followed.

Component placement and orientation

Component placement and orientation play an important role in the reliability of board manufacturing. For example, when using wave soldering, components must be oriented parallel to the wave direction, placed bridge soldering or open circuit.

Power thermal management

Circuit board alignment thickness, number of layers, heat path continuity and board surface are all factors that affect the climate of the running components. When the absorption exceeds 10mW or current exceeds 10mA components must be properly thermal management and power management components.

Component Sequence

Place finer components first, followed by smaller parts. In addition, analog or hybrid components must be placed in a specific PCB area, separate from its digital components.

DRC principle

DRC (Design Rule Checking) is an important assembly part of electronic design automation

PCB assembly in vehicles

Printed circuit boards provide mechanical support and electrical connections for the different components of a vehicle and have a wealth of uses in vehicles. Our requirements for safety, comfort and connectivity are fulfilled by circuit board design for.

  1. airbag deployment
  2. Automotive audio and video equipment
  3. global positioning systems
  4. anti-lock braking systems
  5. vehicle communication devices
  6. LED brake lights
  7. remote diagnostic system
  8. transmission sensors

Why use them?

With the age of vehicle advancement, the automobile has evolved into a collection of complex systems and software. The popularity of vehicle printed circuit boards is not only attributed to their functionality but also has many other benefits.

Importantly, your PCB manufacturer has the flexibility to make PCBs that fit the vehicle’s electronic control device system. Almost everything you see digitally displayed in a vehicle is likely controlled by the PCBs. In the future development of automotive electronics, we expect cars to become increasingly intelligent and environmentally friendly. Therefore, PCB assembly suppliers are an indispensable part of the automotive industry.
