Background technology

Flex circuit application, also known as FPC or flexible printed circuit board, flexible printed circuit board (Flexible Printed Circuit Board) printed circuit made with flexible insulating substrate, there is many rigid printed circuit boards The advantage not possessed.Such as it can with free bend, wind, fold, can require arbitrarily to arrange according to space layout, and in three-dimensional Space is arbitrarily moved and stretches, thus reaches components and parts assembling and the integration of wire connection.Utilize FPC can be substantially reduced electronics The volume of product, is suitable for the needs that electronic product develops to high density, miniaturization, highly reliable direction.Therefore, FPC is in space flight, army It is widely used on the fields such as thing, mobile communication, laptop computer, computer peripheral equipment, PDA, digital camera or product. FPC Flexible Printed Circuit flexible electric circuit board is also known as flexible circuit board；With mylar or polyimides For base material, by being etched on Copper Foil the one forming circuit and make, there is height reliability, the printing electricity of excellent flexibility Road.

FPC also has good thermal diffusivity and solderability and is prone to the advantages such as load, integrated cost be relatively low, and soft or hard combines Design compensate for slightly not enough in element bearing capacity of flexible parent metal the most to a certain extent.

Flexible print circuit board have one side, two-sided and multi-layer sheet point.The base material used with polyimide copper clad lamination is Main.This kind of material thermal resistance height, good stability of the dimension, pass through with the coverlay having mechanical protection and good electrical insulating properties concurrently Compacting forms final products.Two-sided, the top layer of multilayer printed wiring board and inner conductor realize ectonexine circuit by metallization Electrical connection.

Utility model content

Technical problem to be solved in the utility model is to provide the panel computer wind of a kind of low cost, high-performance stability Fan flex circuit application.

For solving above-mentioned technical problem, the technical scheme that this utility model is used is:

A kind of panel computer fan flex circuit application, longitudinal direction includes stiffening plate, covering that left end aligns successively Film I, backing material plate and coverlay II, described stiffening plate, coverlay I, backing material plate and coverlay II are fixing successively to be pasted, described reinforcement Plate is positioned over the left end of film I upper surface, described coverlay I and coverlay II be respectively overlay in backing material plate upper surface and Lower surface, the right-hand end of described coverlay I upper surface is stained with tack coat I, and described coverlay II lower surface is stained with tack coat II, Described tack coat II is positioned over the middle part of film II.

Further preferably, described stiffening plate is polyimides stiffening plate or polyester stiffening plate, described stiffening plate a length of The 1/3 of coverlay I length.

Further preferably, described backing material plate is polyimide copper clad lamination, and the thickness of described backing material plate is 125 μm.

Further preferably, described coverlay I and coverlay II is polyester resin film, described coverlay I and coverlay II Thickness be 9～18 μm.

Further preferably, described coverlay I and coverlay II is 1: 1 with the length ratio of backing material plate.

Further preferably, the thickness of described stiffening plate is 20～35 μm.

Compared to prior art, this utility model panel computer fan flex circuit application has the beneficial effect that

This utility model panel computer fan flex circuit application has simple in construction, resistance to bending, pressure, heat-resisting, use The advantages such as convenience, high sensitivity, life-span length, backing material plate of the present utility model uses polyimide copper clad lamination, this copper coin purity height, Even structure, its crystal orientation is parallel to line alignment, thus substantially increases the toughness of backing material plate, simultaneously to base before circuit makes Material plate carries out high-temperature heat treatment, makes the flexural property of backing material plate again strengthen, thus is effectively improved of the present utility model scratching Qu Nengli.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model panel computer fan flex circuit application.

Detailed description of the invention

With specific embodiment, technical solutions of the utility model are described further below in conjunction with the accompanying drawings.

As it is shown in figure 1, panel computer fan flex circuit application of the present utility model, longitudinal direction includes left end successively Stiffening plate 5, coverlay I2, backing material plate 1 and the coverlay II3 of alignment, stiffening plate 5, coverlay I2, backing material plate 1 and coverlay II3 Fixing successively and paste, stiffening plate 4 is positioned over the left end of film I2 upper surface, coverlay I2 and coverlay II3 and is covered each by In the upper and lower surface of backing material plate 1, it is waterproof that the right-hand end of coverlay I2 upper surface is stained with tack coat I4, tack coat I4 Tack coat, its thickness is 15～20 μm, and the 1/3 of a length of coverlay I2 length of tack coat I4, in the middle part of coverlay II3 lower surface Being stained with tack coat II6, tack coat II6 is water-proof tack coat, and its thickness is 15～20 μm, a length of coverlay of tack coat II6 The 1/3 of II3 length, tack coat I4, coverlay I2, backing material plate 1 and the alignment of coverlay II3 right-hand end.

This utility model panel computer fan flex circuit application stiffening plate 4 is polyimides stiffening plate or polyester reinforcement Plate, the 1/3 of a length of coverlay I2 length of stiffening plate 4, the thickness of stiffening plate 4 is 20～35 μm, and the effect of stiffening plate 4 is to add The intensity of strong backing material plate 1, position difference i.e. shows that the position that product needed is strengthened is different.

This utility model panel computer fan flex circuit application backing material plate 1 is polyimide copper clad lamination, the thickness of backing material plate 1 Degree is 125 μm, and backing material plate 1 selects the rolled copper foil material of high-purity, even structure so that it is crystal orientation is parallel to line alignment, carries The high toughness of backing material plate 1, carries out high-temperature heat treatment to backing material plate 1 before circuit makes simultaneously, makes Copper Foil flexural property again Strengthen, also eliminate contraction and stress that polyimide film (PI) produces because of the moisture absorption, further increase the flexure of backing material plate 1 Ability；Coverlay I2 and coverlay II3 is polyester resin film, and the thickness of coverlay I2 and coverlay II3 is 9～18 μm, covers Epiphragma I2 and coverlay II3 can carry out hands weldering or low melting point welding, has excellent adhesive property and prominent flexibility, can enter Row alternating bending folds, and coverlay I2 and coverlay II3 is 1: 1 with the length ratio of backing material plate 1.Coverlay I2 and coverlay II3 Play the effect of protection backing material plate 1 copper face, it is possible to effectively prevent copper face from aoxidizing, dirty etc..

Panel computer fan flex circuit application simple in construction of the present utility model, resistance to bending, pressure, heat-resisting, user Just, high sensitivity, life-span are long；Stiffening plate 5 in structure, coverlay I2, backing material plate 1, coverlay II3, tack coat I4, tack coat II6 all uses halogen-free material；Pliability height, compact, use flexibly, are conducive to transport warehousing and reduce manufacturing cost.
