What is FPC
FPC (flexible circuit board) is a type of PCB, also known as “soft board”. FPC is made of flexible substrates such as polyimide or polyester film, which has the advantages of high wiring density, light weight, thin thickness, bendability, and high flexibility, and can withstand millions of dynamic bending without damaging the wires According to the requirements of the space layout, it can move and expand at will, realize three-dimensional assembly, and achieve the effect of integrating component assembly and wire connection, which has advantages that other types of circuit boards cannot match.
Multi-layer FPC circuit board
Application: Mobile Phone
Focus on the light weight and thin thickness of the flexible circuit board. It can effectively save the product volume, and easily connect the battery, microphone, and buttons into one.
Computer and LCD screen
Utilize the integrated circuit configuration of the flexible circuit board and the thin thickness. Convert the digital signal into a picture and present it through the LCD screen;
CD player
Focusing on the three-dimensional assembly characteristics and thin thickness of the flexible circuit board, it turns the huge CD into a good companion;
disk drive
Regardless of hard disk or floppy disk, they all rely on the high flexibility of FPC and the ultra-thin thickness of 0.1mm to complete fast reading data, whether it is a PC or NOTEBOOK;
latest use
The components of the suspension circuit (Su printed ensi. n cireuit) of the hard disk drive (HDD, hard disk drive) and the xe package board.
future development
Based on the vast market of China’s FPC, large enterprises in Japan, the United States, and Taiwan have already set up factories in China. By 2012, flexible circuit boards had grown as much as rigid circuit boards. However, if a new product follows the law of “beginning-development-climax-decline-elimination”, FPC is now in the area between climax and decline, and flexible boards will continue to occupy market share until there is no product that can replace flexible boards , it must innovate, and only innovation can make it jump out of this vicious circle.
So, what aspects will FPC continue to innovate in the future? Mainly in four aspects:
1. Thickness. The thickness of FPC must be more flexible and must be made thinner;
2. Folding resistance. Bending is an inherent characteristic of FPC. The future FPC must have stronger folding resistance and must exceed 10,000 times. Of course, this requires a better substrate;
3. Price. At this stage, the price of FPC is much higher than that of PCB. If the price of FPC falls, the market will definitely be much wider.
4. Technological level. In order to meet various requirements, the FPC process must be upgraded, and the minimum aperture and minimum line width/line spacing must meet higher requirements.
Therefore, the relevant innovation, development and upgrading of FPC from these four aspects can make it usher in the second spring!
What is a PCB
PCB (Printed Circuit Board), the Chinese name is printed circuit board, referred to as printed board, is one of the important components of the electronics industry. Almost every kind of electronic equipment, ranging from electronic watches and calculators to computers, communication electronic equipment, and military weapon systems, as long as there are electronic components such as integrated circuits, printed boards are used for the electrical interconnection between them. . In the larger electronic product research process, the most basic success factors are the design, documentation and fabrication of the product’s printed board. The design and manufacturing quality of printed boards directly affect the quality and cost of the entire product, and even lead to the success or failure of commercial competition.
The role of the PCB
The role of PCB After electronic equipment adopts printed boards, due to the consistency of similar printed boards, errors in manual wiring can be avoided, and automatic insertion or placement, automatic soldering, and automatic detection of electronic components can be realized, ensuring electronic reliability. The quality of the equipment improves labor productivity, reduces costs, and facilitates maintenance.
Development of PCBs
Printed boards have developed from single-layer to double-sided, multi-layer and flexible, and still maintain their own development trends. Due to the continuous development in the direction of high precision, high density and high reliability, continuous reduction in size, cost reduction and performance improvement, printed boards still maintain strong vitality in the development of future electronic equipment.
A summary of domestic and foreign discussions on the future development trend of printed board manufacturing technology is basically the same, that is, to high density, high precision, fine aperture, thin wire, fine pitch, high reliability, multi-layer, high-speed transmission, light weight, Developing in the direction of thinness, it is also developing in the direction of improving productivity, reducing costs, reducing pollution, and adapting to multi-variety and small-batch production. The technical development level of printed circuits is generally represented by the line width, aperture, and plate thickness/aperture ratio of the printed circuit board.
Summarize
In recent years, the market of consumer electronic products led by mobile electronic devices such as smart phones and tablet computers has grown rapidly, and the trend of miniaturization and thinning of devices has become more and more obvious. What follows is that the traditional PCB can no longer meet the requirements of the product. For this reason, major manufacturers have begun to research new technologies to replace PCBs. Among them, FPC, as the most popular technology, is becoming the main connection of electronic equipment. Accessories.
In addition, the rapid rise of emerging consumer electronics markets such as wearable smart devices and drones has also brought new growth space for FPC products. At the same time, the trend of display and touch control of various electronic products has also enabled FPC to enter a wider application space with the help of small and medium-sized LCD screens and touch screens, and the market demand is growing day by day.
The latest report shows that in the future, flexible electronic technology will drive a trillion-scale market, which is an opportunity for my country to strive for leapfrog development of the electronics industry and become a national pillar industry.
