Talking about the prospects of development and application of flexible circuit board

- Jul 18, 2016-

First, A flexible circuit board Overview


FPC (Flexible Printed Circuit, FPC), also known as flexible circuit boards, flexible circuit boards, referred to as the soft board or FPC, with a high wiring density, light weight, thin, less wiring space constraints, high flexibility, etc. the advantages of electronic products in full compliance with the development trend of short, light is an effective solution to meet the miniaturization of electronic products and mobile requirements. FPC free to bend, winding, folding, and can withstand millions of times without damaging the dynamic bending wire, can be in accordance with the requirements of any space layout arrangements, and any movement in three-dimensional space and flexibility to achieve the assembly of components and wires integration effect. FPC can greatly reduce the size and weight of electronic products, electronic products need to apply to high density, small size, high reliability direction of development. Therefore, widely used in PC and peripheral products, automotive electronics, medical devices, communications and consumer electronics products and other fields.

FPCA (Flexible Printed Circuit Assembly) products, the FPC assembly, extending the FPC business chain, the industry mainstream technology for SMT. SMT (Surface Mount Technology) electronic circuit that is surface mount technology, also known as surface mount or surface mount technology. It is a short lead or the leadless surface mount components (referred to as SMC / SMD, said the Chinese SMT Components) mounted on a printed circuit board or other substrate surfaces, by reflow soldering or dip methods welding assembly mounted to a circuit connected to technology. SMT technology application has the following advantages:

First, high packing density, electronic products, small size, light weight, about chip component size and weight of only traditional instrumentation components 1/10, generally after using SMT, electronic products smaller in size by 40% to 60% weight reduction 60% to 80%. Second, high reliability, seismic capability, solder joint defect rate, good high-frequency characteristics. Third, reduce the electromagnetic and radio frequency interference. Fourth, easy to automate, improve production efficiency. Fifth, save materials, energy, equipment, manpower and time.


Second, the flexible circuit board applications


Electronic products light, thin, short, small demand trends, so that the army quickly FPC supplies to civilian steering consumer electronics products in recent years emerged in almost all of the high-tech electronic products uses a lot of the flexible circuit board. Japanese scholars call history research positions in "high-density flexible printed circuit board," a book, said: Almost all of the internal electrical products are used in flexible circuit boards, and now it would be difficult to find without using flexible circuit board slightly more complex electronic products a.


Third, the flexible circuit board market prospects


"The current focus on high-tech industrialization Field Guide (2011) priority development" is mentioned: the National Development and Reform Commission, Ministry of Science, Industry and Information Technology, Ministry of Commerce and Information Property Office decided that the high-end chip components, high density multilayer printed circuit board and flexible circuit board as one of the high-tech industry in the field of information currently focused on priority development. With the development of information technology, intelligent building, the market demand for flexible circuit boards will also be growing.

(1) mobile phone market. Mobile handsets, FPC in the phone primarily as folding and rotating parts of the signal connected parts, general mobile phone application within three or more FPC, with the emphasis on light, thin, short, small, high feature phones popular, driving FPC demand. FPC can be used in mobile phones bends, LCD module, camera module, button, side buttons, antenna, battery control and other functions. FPC currently turning point in the mobile phone (Hinge Part) most applications, a common folder-type, slide-type, clamshell perspective to the rotary body, multi-sided or multilayer FPC design, FPC is the maximum value in mobile applications By. As for the key FPC, camera modules, antenna or battery FPC, compared to handset designers selective design. In the above-described optional feature will be gradually incorporated into the design of the phone standardization situation and help improve the amount of FPC. 2014 communication operation industry statistical bulletin issued by the Ministry of Industry and Information Technology show that in 2014, a net increase of 39.426 million telephone subscribers nationwide, a total of 1.536 billion, an increase of 2.6 percent, down 5 percentage points from last year. Among them, a net increase of 56.98 million mobile phone users, a total of 1.286 billion mobile phone user penetration rate of 94.5 / 100 people, over the previous year 3.7 / per person. While Apple and Android phones as the leading smart phone has become a mobile phone user's choice, according to "2013--2014 China's Mobile Phone / Smartphone Market Annual General Report" predicts that in 2015 the global smart phone users the proportion of first time more than the world's population one-tenth, 2018, one-third of the world's consumers will be smart phone users, the total number of more than 2.56 billion people. Smartphone User Index 2018 represents half the world's mobile phone users, which means feature phones will become a minority in the field of electronic communications. FPC smartphone content higher than the general electronic products, smart phones using the FPC 5 to 12, 1 to 5 higher than feature phones, two to three times each FPC value of about smartphones feature phones. Such a huge market will inevitably bring with it the rapid development in the field of smart phone camera modules, antennas, monitors, USB cable, etc. are inseparable FPC figure.

(2) automotive electronics market. Under the trend of automotive electronics, vehicle control systems, such as the dashboard display, and high signal transmission capacity and high reliability requirements of the air quality, stereos, monitors, sensors, etc. began to show its advantages with the FPC, the FPC assembly precision under the trend, coupled with the body, three-dimensional structure of the distribution area of narrow and bending characteristics, the FPC assembly better meet the design requirements. According to the China Association of Automobile Manufacturers, in 2014, China's car sales rose 7.26% and 6.86%. Wherein the passenger car sales rose 10.15% and 9.89%, is still the main growth.

(3) medical monitoring equipment. Over the past ten years, China's medical device market size in 2001 from 179 billion yuan to 212 billion yuan in 2013, excluding the price factor, 13 years, an increase of 11.84 times. According to the China Association for Medical Devices Branch of medical supplies sample survey, 2014 annual national medical equipment sales volume of about 255.6 billion yuan, 212 billion yuan more than last year increased by 43.6 billion yuan, an increase of 20.06%. Medical monitoring equipment as hospitals and other medical institutions, conventional medical equipment, has gradually become a large and medium-sized hospitals are commonly used. With the rapid development of China's economy, the national attention on primary health care and health system at the county level, towns, communities, and in promoting common aging, two-child policy, consumption upgrade, medical reform investment, policy support and other internal and external demand, as well as at present, the overall level remained at lower levels, medical monitoring equipment is still considerable room for development, the domestic medical equipment industry development prospects worth the wait.


In summary, with community information, intelligence requirements continue to increase, and almost penetrated into all walks of life, as mentioned in the text, it has been difficult to find without using FPC and FPC assembly slightly more complex electronic products the . With the state will further increase investment in electronic information technology in various fields, the field of electronic information downstream accelerated pace, will inevitably bring about the development of FPC and FPC assembly industry. Meanwhile, 4G business has been in full swing across the country, it will also be a flexible printed circuit board industry to bring new development opportunities.
