Abstract
The utility model discloses a flexible printed circuit board for an LED liquid crystal display. The flexible printed circuit board comprises a substrate plate and covering films, wherein the covering films cover on the upper surface and the lower surface of the substrate plate respectively, the length of the covering film is 2/3-3/4 of that of the substrate plate, the surface of the covering film is covered by a reinforcement plate, and the length of the reinforcement plate is 1/2-2/3 of that of the covering film. The flexible printed circuit board for the LED liquid crystal display has the advantages of simple structure, bending resistance, pressure resistance, heat resistance, convenient use, high sensitivity, long service life and the like. The substrate plate of the flexible printed circuit board adopts a polymide copper-clad plate, wherein the copper plate is high in purity and uniform in structure, and the crystal orientation of the copper plate is parallel to the route of a circuit, thereby greatly improving the toughness of the substrate plate. Meanwhile, the substrate plate is subjected to high-temperature treatment before the circuit is prepared, thereby enabling the flexural property of the substrate plate to be further enhanced, and effectively improving the flexural capacity of the flexible printed circuit board.
Description
Technical field
The utility model relates to a kind of LED liquid crystal display flex circuit application.
Background technology
Flex circuit application, claims again Flexible Printed Circuit or flexible printed circuit board, and flexible printed circuit board (FlexiblePrinted Circuit Board) is the printed circuit made from flexible insulating substrate, has advantages of that many rigid printed circuit boards do not possess.For example it can free bend, coiling, folding, can require to arrange arbitrarily according to space layout, and mobile and flexible arbitrarily at three dimensions, thereby reach integrated that components and parts assembling is connected with wire.Utilize FPC can greatly dwindle the volume of electronic product, applicable electronic product is to the needs of high density, miniaturization, highly reliable future development.Therefore, FPC is widely used on the fields such as space flight, military affairs, mobile communication, laptop computer, computer peripheral equipment, PDA, digital camera or product.FPC---FlexiblePrinted Circuit flexible electric circuit board claims again flexible circuit board; Take mylar or polyimides as base material, by being etched in form on Copper Foil that circuit makes a kind of, there is height reliability, the printed circuit of excellent flexibility.
FPC also has good thermal diffusivity and solderability and is easy to the advantages such as load, integrated cost be lower, and the design of soft or hard combination has also made up slightly not enough in element bearing capacity of flexible parent metal to a certain extent.
Flexible print circuit board have one side, two-sided and multi-layer sheet minute.The base material adopting be take polyimide copper clad lamination as main.This kind of material thermal resistance is high, good stability of the dimension, forms final products with the coverlay that has mechanical protection and good electrical insulation property concurrently by compacting.Top layer and inner conductor two-sided, multilayer printed wiring board are realized the electrical connection of ectonexine circuit by metallization.
Utility model content
Technical problem to be solved in the utility model is to provide the LED liquid crystal display flex circuit application of a kind of low cost, high-performance stability.

As preferably, the thickness of described coverlay is 5-30 μ m.
As preferably, described stiffening plate is polyimides stiffening plate or polyester stiffening plate.
As preferably, the thickness of described stiffening plate is 10-40 μ m.
Beneficial effect: than prior art, LED liquid crystal display of the present utility model has the advantages such as simple in structure, resistance to bending, withstand voltage, heat-resisting, easy to use, high sensitivity, life-span be long with flex circuit application, backing material plate of the present utility model adopts polyimide copper clad lamination, this copper coin purity is high, even structure, its crystal orientation is parallel to line alignment, thereby greatly improved the toughness of backing material plate, before circuit is made, backing material plate is carried out to high-temperature heat treatment simultaneously, the flexural property of backing material plate is strengthened again, thereby effectively improved bending ability of the present utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of flex circuit application for the utility model LED liquid crystal display.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated:
As shown in Figure 1, a kind of LED liquid crystal display flex circuit application, the coverlay 2 that comprises backing material plate 1 and cover respectively backing material plate 1 upper surface and lower surface, wherein, the length of coverlay 2 is 2/3～3/4 of backing material plate 1 length, on the surface of coverlay 2, be covered with stiffening plate 3, the length of described stiffening plate 3 is 1/2～2/3 of coverlay 2 length; Backing material plate 1 is polyimide copper clad lamination, and this copper coin purity is high, even structure, and its crystal orientation is parallel to line alignment, thereby has greatly improved the toughness of backing material plate; Coverlay 2 is polyester resin film, and coverlay 2 can carry out the welding of hand weldering or low melting point, has good adhesive property and outstanding flexible, can carry out alternating bending folding, and the thickness of coverlay 2 is 5-30 μ m; Stiffening plate 3 is polyimides stiffening plate or polyester stiffening plate, and the thickness of stiffening plate 3 is 10-40 μ m.
The outer surface that covers the coverlay 2 of backing material plate 1 lower surface is provided with stiffening plate 3.Same one end of backing material plate 1, coverlay 2 and stiffening plate 3 is mutually to it.
LED liquid crystal display of the present utility model with flex circuit application tool by advantages such as simple in structure, resistance to bending, withstand voltage, heat-resisting, easy to use, high sensitivity, life-span are long.
Obviously, above-described embodiment is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And these belong to apparent variation that spirit of the present utility model extended out or change still among protection range of the present utility model.
