Flexible circuit board (FPC) is becoming more and more popular in the context of the rapid development of smart phones as the representative of electronic devices to the direction of miniaturization.

In the new energy automobile market, FPC flexible circuit boards are widely used in GPS devices, LCD displays, radio devices, and entertainment devices such as DVD players.

In terms of smart wear, smartwatches, smart bracelets, VR helmets, etc. all use FPC flexible circuit boards in the chip, sensor, and machine design.

1. The innovative function of smartphone pushes the use and development of FPC to a new height. The arrival of the era of full-screen smartphones promotes the re-layout and trend of the FPC industry chain. The wide application of flexible LED screens greatly stimulates the demand of the FPC flexible circuit board.

In addition, the fingerprint recognition scheme under the screen of the smartphone promotes the development of the FPC flexible circuit board toward the direction of double-layer ultra-thin and ultra-narrow.

Flexible PCB can be used in folding, rotating, LCD module, camera module, button, side key, antenna, battery control and other functions of mobile phones. Generally, more than three flexible PCBs are used in mobile phones. With the popularity of light, thin, short and small smartphones, the demand for flexible PCB will increase.

2:The development trend of automobile automation, electrification, and networking of new energy vehicles breed new opportunities and new development of the FPC flexible circuit board market with reliable performance. At the same time, the increasing proportion of automobile electronic cost not only promotes the development of high-quality FPC with specialized production, but also brings new growth momentum to well-reputable FPC manufacturers, and also promotes the substantial increase of their output value.

In addition to mobile phones, the automotive electronics market is also the main battlefield of FPC. Vehicle control systems, such as dashboard display, air quality, sound, display, sensors, etc. The requirements of high signal transmission and high reliability make FPC begin to show its advantages.

3:With the rapid expansion of the scale of a series of wearable devices, there is no doubt that FPC flexible circuit boards tend to be lighter and thinner. The high compatibility between high-end FPC and wearable devices increases the demand and development of FPC.

In addition, the wearable market, especially the rise of virtual reality and augmented reality technology, has enabled FPC to further develop both in structure and performance.

It can be seen that whether it is a small smartphone, a large car, or a portable wearable device, as an innovative terminal product today, FPC flexible circuit board is developing rapidly, and in the future, FPC will continue to move towards miniaturization and thinning along with mobile consumer electronics products.

At the same time, it will gradually move towards automation with the investment of flexible circuit board manufacturers in R&D and the expansion of production capacity.

Flexible PCB is widely used in mobile phones, especially smartphones. It can be divided into FPC for camera, FPC for module, FPC for battery, FPC for capacitive screen, FPC for keypad, FPC for antenna, etc.

Advantages of Flexible Circuit Board

Flexible printed circuit boards are printed circuits made of flexible insulating substrates, which have many advantages that Rigid printed circuit boards do not have.

1. Free bending, winding and folding, arbitrary arrangement according to space layout requirements, and arbitrary movement and expansion in three-dimensional space, so as to achieve the integration of component assembly and wire connection;

2. The volume and weight of electronic products can be greatly reduced by using FPC, which is suitable for the development of electronic products in the direction of high density, miniaturization, and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products.

3. FPC also has the advantages of good heat dissipation and weldability, easy assembly and low comprehensive cost. The design of soft-hard combination also makes up for the slight deficiency of flexible substrates in component bearing capacity to a certain extent.

Main raw materials of FPC

Its main raw materials are right: 1, base material, 2, covering film, 3, reinforcing, 4, other auxiliary materials.

1. Substrate

1.1 Rubber Substrate

There are three main parts of adhesive base material: copper foil, glue, and PI. There are two kinds of single-sided base material and double-sided base material. Only one side of copper foil is single-sided base material, and two sides of copper foil are double-sided base material.

1.2 Rubber-free Substrate

The non-glue base material is the base material without the glue layer. Compared with ordinary glue base material, it has less middle glue layer, only copper foil, and PI. It has thinner, better dimensional stability, higher heat resistance, higher bending resistance, better chemical resistance, and other advantages than glue base material. Now it has been widely used.

Copper foil: At present, the thickness of common copper foil has the following specifications: 1OZ, 1/2OZ, 1/3OZ. Now, the thinner copper foil with 1/4OZ thickness is introduced. But at present, this kind of material has been used in our country and is being used in the ultra-fine line (line width and line spacing are below 0.05MM). With the increasing requirements of customers, this kind of material will be widely used in the future.

2. Covering film

There are three main parts: release paper, glue, and PI, which are only glue and PI in the final product. The release paper will be torn off in the production process and will no longer be used (there is foreign body on its protective glue).

3, reinforce

For the specific use of FPC materials, use in a specific part of the product to increase the support strength, make up for the FPC more "soft" characteristics.

At present, there are several kinds of commonly used reinforcing materials as follows:

1) FR4 reinforcing: The main components are glass fiber cloth and epoxy resin, which are the same as FR4 used in PCB.

2) Reinforcement of steel sheet: Composition of steel, with strong hardness and support strength;

3) PI reinforcing: The same as the covering film, there are three parts of PI and glued paper, but the PI layer is thicker, which can be produced proportionally from 2MIL to 9MIL.

4.Other auxiliary materials

1) Pure glue: This adhesive film is a kind of heat-curable acrylate adhesive film, which consists of protective paper/release film and a layer of glue. It is mainly used for laminating board, soft-hard bonding board and FR-4/steel sheet reinforcing board.

2) Electromagnetic protective film: paste on the surface of the board to shield.

3) Pure copper foil: only copper foil, mainly used for hollow board production.

There are six types of FPC:

A. Single-sided Flexible Circuit Board: Only one side has a circuit.

B. Double-sided flexible PCB: There are circuits on both sides.

C. Hollow-out Flexible PCB board: also known as window board.

D. Layered Flexible PCB board: two-sided circuits (separate).

E. Multilayer Flexible PCB board: two or more layers.

F. Rigid-Flexible PCB: Products Combining Flexible PCB with Rigid PCB.

At present, we are the main supplier of flexible circuit boards for smart wearing equipment. In addition, we also produce flexible circuit boards for 5G base stations, high-frequency PCB, high-speed PCB, radio frequency PCB, high-precision PCBs and Flexible Circuit Board Assembly services.
