Flex circuits may make car wires disappear

We live in an electrified world, and we use various electronic products, such as automobiles, mobile phones, home appliances, medical equipment, robots, etc. Perhaps shortly, the human spirit will also exist in the electronic world. And among these electronic products, what is the most important? It’s a circuit board, and any electronic product must have a circuit board (PCB). With the development of technology, we hope that more electronic products need to be more flexible, more convenient, smaller in size, etc., so the connection technology of our circuit boards and circuit boards(flex circuits) are also changing with each passing day.

the market of Flexible Printed Circuit

PCB is a printed circuit board, or a hardboard, also known as a printed circuit board. Generally, FR4 is used as the base material and cannot be bent. Therefore, it is usually used in places that do not require bending and have relatively complex strength, such as computer motherboards and mobile phone motherboards. Wait, the available chips are on the motherboard, and the opposite is the Adagio, which is the FPC we are talking about today.

What is FPC? The full name is Flexible Printed Circuit.

The entire FPC market is expected to reach $23.4 billion by 2025, according to Lucintel. With a compound annual growth rate of 5% to 7% from 2020 to 2025. The primary growth comes from the telecommunications industry, connected devices. Innovative car electronics, etc., and the automotive industry has the highest growth rate. In other words, the era of smart cars will create ups and downs in many sectors. For automobiles, whether it is a fuel vehicle or an innovative vehicle, there are many FPC applications, mainly in the automotive electronics sector. Automotive electronics is the general term for automotive electronic control devices and electronic control devices. It includes explicitly engine control system, chassis control system, and automotive electronic control system; from the perspective of structure and space. new energy vehicles will use many FPC instead of wiring harnesses in the future, which will be implemented in multiple parts of the car, so FPC technology is used in automotive electronics. , especially in intelligent vehicles is a significant trend, especially in battery BMS, vehicle lighting systems, door control systems, camera modules, etc.; generally, there will be more than 100 FPC applications on an electric car (this is captured from the Internet). It has not been verified, and it is for reference only) The FPC in the battery BMS and the vehicle camera module has the highest application value and vital development areas.

Advantages of FPC:

FPC flexible circuits can be twisted, bent, and folded, improving the space utilization and flexibility of products and meeting the development needs of miniaturization and high density of electronic products. FPC can move and expand arbitrarily in three-dimensional space to achieve the integration of component assembly and the wire connection, which is conducive to reducing the volume and weight of electronic products, reducing assembly processes to a certain extent, and enhancing reliability. FPC can withstand millions of times of dynamic bending, can be well used in the internal connection system of the product, and become an indispensable part of the product function.
FPC can realize the integration of small, light, and thin, provide excellent electrical performance, quickly transmit electrical signals, and make product components work well. FPC is divided into four types: single-sided and double-sided, multi-layer flexible board, and rigid-flexible board. It is mainly made of polyimide or polyester film as the primary material, and other constituent materials include insulating film, conductor, and adhesive. FPC needs to be pre-processed before production. It is necessary to complete the final inspection before packaging and shipping during the production process.

Application of FPC flexible circuit board in the automobile industry

Four major applications of automotive FPC flexible circuit boards in the automotive industry

  1. A new generation of automotive automatic safety systems
    More and more FPC flexible circuit board[1] technology is used in automobiles. The super multi-view head-up display of the new generation of automatic safety system automobiles and the automatic adaptive cruise control system that is not interfered with by the outside world will be introduced. This FPC flexible circuit board technology allows the driver to have a multi-view independent display and let go of driving after entering the destination.
  2. V2V communication
    Another new technology of V2V communication its function is to allow two cars to communicate with each other, recording the road and surrounding objects. This type of FPC flexible circuit board technology is similar to driverless vehicles and can help reduce accidents. Even if someone runs a red light, this technology can remind you of the road ahead, allowing you to avoid the risk.
  3. Network car
    This is a new technology in the automotive industry. It is suitable for taxis and does not require drivers. The FPC flexible circuit board can directly communicate with all other electronic taxis in the city through the Internet, sharing geographic location and car model information. Just an intelligent price call can summon a networked car when you want to travel, and this car technology is expected to be used in major cities around the world.
  4. Electric vehicles
    Electric cars are a new way to save gasoline, but they are not yet widespread, and they are more expensive than other regular cars. With the emergence of electric vehicles, many car manufacturers are also researching methods to improve point efficiency. A professional FPC flexible circuit board material limited engineering company has made a breakthrough in this technology. They make lithium-ion batteries at least produce more electrical energy within the time.
