What is a PCB?
PCB (Printed Circuit Board), Chinese name is a printed circuit board, referred to as printed board, is one of the important components of the electronics industry. Almost every electronic device, small to electronic watches, calculator, large to computer, communication electronic equipment, military weapon system, as long as there is an electronic component such as integrated circuit, for the electrical interconnection between them, use printing boards . During a larger electronic product research, the most basic success factor is the design, documentation and manufacturing of the printed board of the product. 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.
PCB role
After the PCB operates, after the printed board, due to the consistency of the same type of printed board, the error of the artificial wiring is avoided, and the electronic components can be automatically inserted or mount, automatic soldering, automatic detection, and ensure electronic The quality of the equipment improves labor productivity, reduces cost, and facilitates maintenance.
Development of PCB
The printed board develops from a single layer to double-sided, multi-layer and flexibility, and still maintains their respective trends. Since the continuous development of high-precision, high density, and high reliability is constantly narrowing volume, reducing cost, improvement, making printed boards in the development of future electronic equipment, still maintained strong vitality.
Surveying the development of the development trend of future printed board production and manufacturing technology is basically consistent, namely, high-density, high precision, pore diameter, thin wire, fine spacing, high reliability, multi-layer, high-speed transmission, lightweight, Thin direction development, in production, while increasing productivity, reducing cost, reducing pollution, adapting to multi-variety, small batch production direction. The technical development level of the printed circuit is generally represented by the line width, aperture, and the thickness / aperture ratio on the printed board.
What is FPC
FPC (flexible circuit board) is one of the PCB, and is also called "soft board." FPC is made of flexible substrate such as polyimide or polyester film, has the advantages of high wiring density, light weight, thin, bendable, flexible, and can withstand millions of dynamic bending without damaging wires. The advantages of other types of circuit boards cannot match.
Multi-layer FPC circuit board
1, application: mobile phone
Heavy weight and thin thickness of the flexible circuit board. It can effectively save product volume, easy to connect the battery, microphone, and button.
2, computer and liquid crystal screen
Using the integrated line configuration of the flexible circuit board, and thin thickness. Turn the digital signal into a picture, and the liquid crystal screen is presented;
3, New Uses: Human Suspension Circuits (SU "ENSI.N CIREUIT and XE Packaging Plates, etc.
4, future development: large enterprises in Japan, the United States, Taiwan countries and regions based on China FPC have been set up in China. By 2012, the flexible circuit board is the same as the rigid circuit board, which has achieved great development. However, if a new product is based on "Start – Calligrase – Decline – Elimination", FPC is now in the area between climax and decline. Without a product can replace the flexible board, the flexible panel should continue to occupy a market share. It is necessary to innovate, only innovation can let it jump out of this strange circle.
What is the future future to innovate in the future?
1, thickness. The thickness of the FPC must be more flexible and must be thinner;
2, and the ability to resist. It can be bent and the future features, future FPC resistance must be stronger, 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 fpc price is now, the market must have a lot.
4, process level. In order to meet many requirements, the FPC process must be upgraded, minimum aperture, and the minimum line width / line distance must reach higher requirements.
Therefore, from these four aspects, the FPC is related to the new innovation, development, upgrade, can make it a second spring!
