What are the differences between flexible circuit board and PCB circuit board  

Flexible circuit board (flexible circuit board) is a kind of PCB, also known as "soft board".  The flexible circuit board With flexible polyimide or polyester film base material is made, with the high density of wiring, light weight, thickness thin, flexible, high flexibility, can withstand the dynamic bending of millions of times and no damage to wire, in accordance with the spatial layout for any move and scale, realize 3 d assembly, components assembly and wire connection integration effect,  It has incomparable advantages over other types of circuit boards.  

Multi-layer flexible circuit board:  

application  

Mobile phone: emphasis on flexible circuit board light weight and thin thickness.  Can effectively save the product volume, easy to connect the battery, microphone, and buttons into one.  

Computers and LCD screens: integrated circuit configuration using flexible circuit boards, and thin thickness.  The conversion of digital signals into a picture that is displayed on a LCD screen  

CD Walkman: emphasis on three dimensional assembly characteristics and thin thickness of flexible circuit board.  Turn the huge CD into a good companion to carry around  

Disk drive: no matter hard disk or soft disk, all rely on FPC's high flexibility and 0.1mm ultra-thin thickness, complete fast data reading.  Whether it's a PC or a NOTEBOOK.  

Latest use: Hard disk drive (HDD,hard disk drive) mount circuit (Su printed ENSI).  N CIreuit) and XE package board, etc  

So, the future of flexible circuit board from what aspects to continue to innovate?  Mainly in four aspects:  

1. Thickness: the thickness of the flexible circuit board must be more flexible and thinner;  

2, folding resistance: can be bent is the inherent characteristics of flexible circuit board, the future of flexible circuit board folding resistance must be stronger, must be more than 10,000 times, of course, this requires a better substrate;  

3, price: at this stage, the price of flexible circuit board is much higher than PCB circuit board. If the price of flexible circuit board comes down, the market will surely be much broader.  

4, process level: in order to meet the requirements of many aspects, the process of flexible circuit board must be upgraded, the minimum aperture, minimum line width/line distance must meet higher requirements.  

Therefore, from these four aspects of the flexible circuit board related innovation, development, upgrading, in order to usher in the second spring!  

What is the PCB  

Printed Circuit Board (PCB) is one of the most important components in the electronic industry.  Almost every electronic device, from electronic watches and calculators to computers, communication electronics, military weapons systems, as long as there are integrated circuits and other electronic components, for the electrical interconnection between them, printed boards are used.  In larger electronic product research, the most fundamental success factor is the design, documentation, and manufacture of the printed board for the product.  The design and manufacturing quality of PCB directly affect the quality and cost of the whole product, and even lead to the success or failure of commercial competition.

The role of PCB board  

After electronic equipment adopts printed board, due to the consistency of similar printed board, the error of manual wiring is avoided, and electronic components can be automatically inserted or mounted, automatic soldering, automatic detection, to ensure the quality of electronic equipment, improve labor productivity, reduce cost, and easy maintenance.  

The development of the PCB  

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 of high precision, high density and high reliability, and constantly reduce the volume, reduce the cost, improve the performance, making the printed board in the future electronic equipment development project, still maintain a strong vitality.  

Were reviewed at home and abroad in the future technology development trend of PCB manufacturing is basically consistent, namely to high density, high precision, small aperture, thin wire, small spacing, high reliability, multiple stratification, high-speed transmission, light weight, thin, on the production at the same time to improve productivity, reduce costs, reduce pollution, to adapt to many varieties, small batch production.  The technical development level of printed circuit is generally represented by the line width, aperture, and thickness/aperture ratio on the printed board.  

conclusion  

In recent years, the market of consumer electronic products led by smart phones, tablet computers and other mobile electronic devices has been growing rapidly, and the trend of miniaturization and lightness of devices has become more and more obvious.  As a result, the traditional PCB has been unable to meet the requirements of the product, so the major manufacturers began to study new technologies to replace PCB, and the flexible PCB, as the most favored technology, is becoming the main connecting parts of electronic equipment.  

In addition, the rapid rise of wearable smart devices, drones and other emerging consumer electronics market has also brought new growth space for flexible circuit board products.  At the same time, the trend of display and touch control of all kinds of electronic products also makes PCB enter a broader application space with the help of small and medium-sized LCD screen and touch screen, and the market demand is growing day by day.  

The latest report shows that in the future, flexible electronic technology will drive a trillion market, is an opportunity for China to strive for the leapfrog development of the electronics industry, can become a pillar industry of the country.
