Application of Automotive PCB in Autonomous Driving

        Autonomous driving has become a rapidly developing and crucial trend in the automotive industry. The widespread application of autonomous driving technology has not only significantly improved the safety and convenience of driving operations, but more importantly, it has fundamentally reshaped people’s daily travel patterns. In the process of autonomous driving technology, automotive PCB plays an indispensable and key role.

 

Autonomous driving technology involves multiple core systems that rely on high-performance, high-reliability automotive PCBs to achieve their functions. Main applications include:

 

 

1) Sensor Systems

Sensors are the "eyes" of autonomous driving and are responsible for collecting data on the surrounding environment. Technologies such as LiDAR, millimeter-wave radar, cameras, and ultrasonic sensors all rely on high-density, multi-layer PCBs. These PCBs support high-speed signal processing and enable the rapid transmission of data collected by sensors to the on-board computing platform. In addition, since autonomous driving requires real-time response, automotive PCB design must ensure signal integrity and anti-interference capabilities.

 

 

2) Control Units

The onboard computing platform for autonomous driving is the core of all data processing, responsible for analyzing and making decisions based on the collected information. Control units typically consist of complex multilayer PCBs, integrating processors, memory, communication modules. Through these PCBs, complex algorithmic calculations such as path planning, object recognition, and real-time decision-making are performed.

 

 

3) Advanced Driver Assistance Systems (ADAS)

ADAS is a key component of autonomous driving, providing functions such as adaptive cruise control, lane -keeping assistance, and collision warning. Automotive PCBs in these systems handle high-frequency signals and data transmission, communicating in real time with sensor systems to ensure the system’s accuracy and reliability.

 

 

4) Communication Systems

Autonomous vehicles need to communicate with other vehicles (V2V) and infrastructure (V2I) to acquire real-time road conditions, navigation information, etc. PCB design is crucial in high-frequency wireless communication modules and in-vehicle networks (such as CAN, LIN, Ethernet). High-quality PCBs can ensure stable transmission of wireless signals and enhance network reliability.

 

 

5) Power System Management

In electric and hybrid vehicles, autonomous driving is particularly important for the management of the powertrain. The role of multilayer PCB in battery management system (BMS) is mainly to monitor battery status, temperature and charging efficiency. This improves the vehicle's range and safety.

What are the Advantages and Disadvantages of the OSP Technology

图片
     With the continuous development of the electronics industry, there are more and more PCB surface treatment technologies, and each technology has its own merits. OSP is a commonly used surface treatment technology process, what are its advantages and disadvantages?       Compared with other surface treatment technologies, OSP is somewhat different.  It uses a chemical method to produce an organic film on the clean bare copper surface, which acts as a barrier between the copper and the air.   OSP is organic, not  metallic,   and its cost is lower than most surface treatment technologies.     Advantages: With this organic film, it can resist the attack of moisture in the air without being oxidized before welding,  can withstand the test of high temperature, maintain good activity, and has a good tinning ability.  This layer of organic film will not cause damage to the sheet material. It can be easily removed by the ...

The Difference between PCB Dry Film and Wet Film

Both the dry film and the wet film of the PCB refer to the raw materials used for the Circuit. The dry film is a kind of high-molecular compound. It generates a polymerization reaction after being irradiated with ultraviolet rays to form a stable substance attached to the surface of the plate, thereby achieving the functions of impedance plating and etching. The wet film is a blue viscous liquid synthesized from a photosensitive resin and is added with a sensitizer, a pigment, a filler, and a solvent. The functions of the dry film and the wet film are basically similar. However, if the surface of the PCB is not flat and a very thin film thickness is required, the PCB manufacturers can consider using a wet film. Moreover, the cost of the wet film is much lower than that of the dry film, so that a large amount of cost can be saved. The wet film has a good filling ability, but does not protective film,  so high exposure energy is required. If it is a perforated PCB, the dry fil...

What PCBA Problems Can AOI Inspect

图片
        With the development of science and technology, the volume of PCBA is getting smaller and more precise, and some defects in processing cannot be distinguished with the naked eye, so AOI has appeared.  So what PCBA problems can AOI inspect?   The working principle of AOI is to first collect and input parameters such as images, component positions, solder joints and other parameters of the good-quality board.   During the inspection, the instrument automatically scans the circuit board and automatically captures the image, and then compares the collected data with the pre-entered parameters to determine whether the characteristics of solder joints, components and other aspects are consistent. If the data is inconsistent, the d efect  will be flagged through the display for maintenance personnel to repair.     AOI is mainly used to inspect solder paste printing, component placement and soldering. For example: too much or too little ...
