Special Demands of New Energy Vehicles on Automotive PCB

        As environmental protection and sustainable development are increasingly valued, new energy vehicles have become the key to the transformation and upgrading of the automotive industry. Compared with traditional fuel vehicles, new energy vehicles show obvious differences in power systems, control systems and intelligent configurations. These differentiated characteristics directly give rise to the specialized demand for automotive PCBs.

1. High Reliability and High Temperature Resistance

1) Demand Analysis

The working environment of new energy vehicles is relatively harsh, especially near batteries, motors and electronic control systems, where automotive PCBs need to withstand high temperatures and currents.

 

 

2) Special Requirements

Material Selection: PCB manufacturers need to select materials with high thermal stability and high temperature resistance, such as polyimide (PI) or FR-4 stiffener materials, to cope with high temperature working environments.

 

 

Reliability Design: Implement reliability design principles, increase circuit redundancy and anti-interference capabilities to ensure stable operation under extreme conditions.

 

 

2. High Power Handling Capability

1) Demand Analysis

New energy vehicles, particularly in electric drive systems, have high power current requirements. For example, the battery management system and motor controller circuit boards need to handle large currents and high voltages.

 

 

2) Special Requirements

Heavy Copper PCB: Heavy copper PCBs (such as 2 OZ or more) are required to support high power transmission and reduce the heat generation during current flow.

 

 

Heat Dissipation Design: Properly designed heat dissipation channels ensure that heat is quickly released during high power operation, preventing the circuit board from overheating and failing.

 

 

3. Electromagnetic Compatibility (EMC)

1) Demand Analysis

The complex electrical systems in new energy vehicles, such as motors, sensors, and wireless communication devices, generate strong electromagnetic interference that can affect the normal operation of automotive PCBs.

 

 

2) Special Requirements

Shielding Design: Appropriate electromagnetic shielding measures, such as metal enclosures and grounding designs, should be incorporated into the PCB design to reduce the impact of electromagnetic interference.

 

 

Grounding and Layering Design: Use appropriate ground distribution and multi-layer PCB design to ensure good electrical performance, reduce crosstalk, and enhance electromagnetic compatibility.

 

 

4. Intelligence and Networking

1) Demand Analysis

With the development of intelligent connected technology, new energy vehicles increasingly rely on various sensors and electronic control units (ECUs) for interaction and decision-making, which raises higher intelligent requirements for automotive PCBs.

 

 

2) Special Requirements

Multifunctional Integration: Automotive PCBs for NEVs need to support multiple communication protocols, such as CAN, LIN, Ethernet, etc., to meet the needs of driving assistance, infotainment and remote monitoring.

 

 

Programmability: Incorporate FPGA or microcontroller applications into the design to facilitate program updates and function expansion, improving system flexibility.

 

 

5. Lightweight and Compact Design

1) Demand Analysis

New energy vehicles, particularly electric vehicles, have strict requirements for vehicle weight. Lightweight design not only improves range but also enhances overall performance.

 

 

2) Special Requirements

Thin PCB and Material Selection: Use thin PCB design and select lightweight but high-strength materials to reduce overall weight.

 

 

Modular Design: Through modular design, multiple functions are integrated into a single PCB, effectively shortening the size, reducing weight and improving layout flexibility.

 

 

6. Cost Control and Production Efficiency

1) Demand Analysis

With increasing market competition in the NEV sector, manufacturing costs and production efficiency directly impact a company's competitiveness.

 

 

2) Special Requirements

Efficient Production Technology: Utilize advanced automotive PCB production technologies, such as laser drilling and high-speed etching, to improve production efficiency and yield.

 

 

Design Optimization: Optimize wiring and component layout during the design phase to reduce material waste and production costs, achieving a balance between cost and performance.

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 ...
