With the continuous progress of society's requirements for information and intelligence, and almost permeate all walks of life, as mentioned in the article, it is difficult to find slightly complex electronic products without FPC and FPC components. The country will further increase the investment in the construction of electronic informatization in various fields. The acceleration of the construction of electronic informatization in the lower categories will certainly promote the development of FPC and FPC components. At the same time, 4G affairs have been spread across the country, which will also bring new opportunities for the flexible printed circuit board profession.

Advantages and disadvantages of flexible circuit board

Strengths:

(1) It can bend, wind and fold freely, organize arbitrarily according to the space layout requirements, move and flex freely in three-dimensional space, and then reach the integration of component installation and wire connection;

(2) Using FPC can greatly reduce the volume and weight of electronic products;

(3) FPC also has outstanding heat dissipation and weldability, easy to assemble and connect, and low cost advantages. The planning of soft and hard combination also makes up for the slight deficiency of flexible base material in component bearing capacity to a certain extent.

Disadvantages:

(1) High one-time initial cost

Because flexible PCBs are planned and made for special applications, the initial circuit planning, wiring and photographic plates require high costs. Unless soft PCB is used for special needs, it is best not to use it in a small amount.

(2) It is difficult to change and repair soft PCB

Once the soft PCB is made, it must be changed from the base drawing or the prepared photo program, so it is not easy to change. Its surface is covered with a protective film, which should be removed before repair and restored after repair, which is a relatively difficult work.

(3) Size constrained

Soft PCB is usually made by batch process when it is not popular, so it cannot be made very long and wide due to the size of production equipment.

(4) Easy to damage due to improper operation

Improper operation of the assembly and connection personnel is easy to cause damage to the soft circuit, and its soldering and rework need to be operated by trained personnel.

Application of flexible circuit board

The demand trend of light, thin, short and small electronic products has made FPC rapidly shift its military supplies to civilian and consumer electronic products. Almost all high-tech electronic products emerging in recent years have selected flexible circuit boards.

In the book "High Density Flexible Printed Circuit Boards", the Japanese scholar Zhao Cang Yanshi said that almost all electrical products use flexible circuit boards. Today, it is difficult to find slightly complex electronic products without flexible circuit boards.

Market prospect of flexible circuit board

(1) Mobile shopping mall. As far as mobile phones are concerned, FPC is mainly used as a part for signal connection of folding, rotating and other parts in mobile phones. Currently, more than three FPCs are used in mobile phones. With the popularity of high-performance mobile phones that are light, thin, short and small, FPC demand is driven.

FPC can be used in mobile phone bending, LCD module, camera module, key, side key, antenna, battery control and other functions.

At present, FPC is most used in the Hinge Part of mobile phones. The common types are folding, sliding, lifting and three-dimensional rotating bodies. Most of them are double-sided or multi-layer FPC planning, which is the largest output value of FPC in mobile phone application.

As for button FPC, camera module, antenna or battery FPC, it is optional planning for mobile phone planners. Under the situation that the above selective functions will gradually be included in the mobile phone standardization planning, it will help to improve the amount of FPC.

According to the 2014 communication and transportation business calculation bulletin issued by the Ministry of Industry and Information Technology, in 2014, the number of telephone users nationwide increased by 39.426 million, reaching 1.536 billion, an increase of 2.6%, down 5 percentage points from the previous year.

During this period, the number of mobile phone users increased by 56.98 million, with a total of 1.286 billion, and the penetration rate of mobile phone users reached 94.5/100, an increase of 3.7/100 over the previous year.

The FPC content of smart phones is higher than that of general electronic products. 5 to 12 FPCs are selected for smart phones, and 1 to 5 FPCs are higher than that of functional phones. The FPC output value of each smart phone is about 2 to 3 times that of functional phones.

Such a huge shopping mall must drive the rapid development of related fields. The camera module, antenna, display, USB cable and so on of smart phones can not be separated from FPC.

(2) Car electronic shopping mall.

Under the trend of car electronization, the requirements of high signal transmission and high reliability of vehicle control systems, such as instrument panel display, air quality, audio, display, sensor, etc., make FPC begin to show its advantages. Under the trend of precision of FPC components, coupled with the three-dimensional structure of the car body, narrow and bent wiring area, the selection of FPC components can better meet the requirements of planning.

According to the data of China Car Industry Association, China's car production and sales increased by 7.26% and 6.86% year on year in 2014. During this period, the production and sales of passenger cars increased by 10.15% and 9.89% year on year.

(3) Medical monitoring equipment.

In the past ten years, the sales plan of China's medical device stores has increased from 17.9 billion yuan in 2001 to 212 billion yuan in 2013. Excluding the impact of price factors, the sales plan has increased by 11.84 times in 13 years. According to the sampling survey of the Medical Device Branch of the China Medical Materials Association, the national medical device sales plan for 2014 was about 25.56 billion yuan, an increase of 43.6 billion yuan from the previous year's 212 billion yuan, with an increase rate of 20.06%.

With the rapid development of China's economy, the country attaches great importance to the construction of the underlying medical and health system at the county level, township level, community level, and other levels. With the promotion of internal and external needs such as aging, the two-child policy, consumption promotion, medical reform investment, policy support, and so on, as well as the current situation that the overall domestic level is maintained at a low level, medical monitoring equipment still has considerable room for development, and the prospect of domestic medical equipment career development is worth waiting.
