Flexible pcb board (FPC), the flexible printed circuit board (Flexible Printed Circuit) short, relative to the rigid circuit board, soft board material characteristics are flexible and easy to turn a light weight, thin, etc., so often applications requiring thin design or movable mechanical design of products, such as mobile phones, notebook computers, monitors, consumer electronics products, touch panels, and IC packaging, etc.
Product structure on the FPC substrate by a soft copper foil (FCCL) and soft insulating layer (usually PI or PET) to adhesive (glue) attached together after the pressure from, and as per customer requirements attached to backing plate or install connectors and other accessories to expand the business scope or provide more complete customer service, therefore, from the purchase of copper, soft copper foil substrate, PI and other raw materials began to flexible pcb Assembly process so far, is the general category of soft board industry.
October 2006 FPC shipments worldwide increased 26.4% year on year, order quantity decreased by 8.7%. As of October 2006 worldwide shipments of soft-board increase of 8.3% year on year, orders fell 6.5% year on year. January to October 2006 the hard plate and soft-board global shipments up situation, the soft board in February to July fell significantly between, and 8,9,10 months remain around 25% year on year growth rate relatively stable trend of hard-board market is relatively few.
2005 World PCB market size of about 420 billion U.S. dollars, of which the output value of 11.3 billion U.S. dollars in Japan, still living in the world. China PCB industry has maintained rapid growth in recent years, the output value of $ 6,000,000,000 in 2003, the output value of $ 8,150,000,000 in 2004, 2005, the output value has reached 10.83 billion U.S. dollars, second only to Japan, China's PCB production value in 2006 is expected to more than 12 billion U.S. dollars. Currently there are around 2800 PCB enterprises, of which about 1,200 in mainland China. The world's leading PCB manufacturers in the vast majority have been set up production bases in China and is actively expanding. Expected in recent years, China remains the world's PCB manufacturers an important destination for investment and transfer. PCB production in China in 2005 exceeded 100 million 1 million square meters, which accounts for nearly half of the multilayer, PCB product structure of China is gradually to higher layers, HDI, the rapid development of high-end products. PCB import and export volume in China in 2003 60 million, 2004 $ 8,900,000,000 in 2005 reached 11.9 billion U.S. dollars, an increase of 34%.
2006-2008 Global Soft Plate in 3G, smart phone, digital camera and monitor demand-driven, you can maintain the growth rate of 8-10%. Aspects of the phone with a soft board will develop towards polarization, a part of the soft and hard toward the multi-layer flexible board or board design to achieve the maximum amount of data transmission capacity and upgrade the pcb assembly quality purposes; and those used in the low-level mobile phones, soft board discarded plywood and soft and hard board design, replaced by soft-sided or double-sided board in order to achieve low-cost replacement purposes, so if handset manufacturers can cut to the low-end mobile phone market, will contribute to a single face and soft-sided board upgrade.
FPC development of the industry are three general direction, first, a soft board with 2L FCCL; currently prevent large-scale application 2L FCCL stumbling block is the price, mainly because of 2L FCCL demand, manufacturers of high gross profit resulting from, once the price competition start shipments will be further expanded, the price will rapidly decline. Although many people believe 3L FCCL will be mainstream though, but we believe the market will go much faster than expected.
Second, the soft and hard board, thanks to slide and rotate the phone in large numbers, while the great efforts of South Korean manufacturers, manufacturers of hard and soft board a Korean blitz object. Most domestic enterprises do not have the soft board the experience of hard board, soft board is a challenge for these manufacturers.
Third, high-density flexible board, 3G era, the phone wiring density increase. Traditional density FPC has not enough. This is why most 3G phones straight sake.
