LCD TV FPC Flexible PCB for LCD TV
Product Description
LCD TV FPC Flexible PCB for LCD TV, LCD Flexible PCB Board, LCD Display Flexible PCB, LCD Backlight Flexible PCB
With the rapid development of LCD TV, smartphone, tablet computer, flat panel TV, LCD, digital camera, DV, wearable equipment and other consumer electronic products, flexible circuit board, referred to as FPC, is being more and more widely used.
LCD TV, as an increasingly popular electronic product for family entertainment and leisure, has entered every family. When people choose LCD TV, they are increasingly demanding that LCD TV can save electricity, be thinner, be more environmentally friendly, have a clearer picture and be more stable.
The popularization of intelligent terminal equipment promotes the vigorous development of FPC industry
Circuit boards are usually divided into two categories, one is rigid circuit board, the other is flexible circuit board. The rigid circuit board is mainly used in household appliances such as refrigerators. The flexible circuit board has become an indispensable component of consumer electronics products such as smartphones because of its lightweight, thin thickness and good flexibility.
At present, the market has higher and higher technical requirements for FPC, such as more and more layers, narrower line width and spacing, smaller aperture and higher flexibility. The key factor to measure the technical content of FPC products is the line width and line spacing. The current limit of Jinghongyi PCB can reach 25 microns, and the quality rate of the printed circuit board can be guaranteed. In addition, high-end FPC products such as multi-layer, blind buried holes, second-order blind holes and so on have also been prepared for production.
Most consumer electronics products use FPC flexible circuit boards or rigid-flexible PCB boards. The driving force for the market demand of flexible circuit boards mainly comes from the development of miniaturization, thinning and intellectualization of consumer electronics. However, with the development and gradual promotion of 5G technology, the electronic information industry will bring a new round of innovation cycle and new growth momentum, and promote the further upgrading of the industrial chain in various related fields.
Characteristics of Flexible Circuit Board
1. Shorten assembly time
2. Less volume than Rigid PCB
It can effectively reduce the volume of the product and make it more convenient to carry.
3. Weight lighter than Rigid PCB
It can reduce the weight of the final product.
4. Thickness is thinner than rigid PCB
It can improve the assembly ability in limited space.
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.
Type of FPC
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.
