Abstract
The utility model discloses a mobile phone flex cable FPC (flexible printed circuit board), which comprises a forged part area, a coverlay, a base material board, a bonding layer and a reinforcement plate, wherein the forged part area is arranged in the hollow area on the coverlay that is arranged on the base material board, the reinforcement plate is arranged at one end below the base material board, and the bonding layer is arranged at the other end below the base material board. The utility model has the advantages of simple structure, bending resistance, pressure resistance, heat resistance, convenient use, high sensitivity, long service life, and the like.
Description
Technical field
The utility model relates to a kind of flex circuit application and manufactures and designs, and is specifically related to manufacturing and designing of flex cable FPC.
Background technology
Flexible printed circuit board FPC (Flexible Printed Circuit Board) is the printed circuit made from flexible insulating substrate, has the advantage 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 move arbitrarily and flexible, thereby reach integrated that the components and parts assembling is connected with lead at three dimensions.Utilize FPC can dwindle the volume of electronic product greatly, be suitable for the needs that electronic product develops to high density, miniaturization, highly reliable direction.Therefore, FPC has obtained using widely on field such as space flight, military affairs, mobile communication, laptop computer, computer peripheral equipment, PDA, digital camera or product.FPC---Flexible Printed Circuit flexible electric circuit board claims flexible circuit board again; With mylar or polyimides is base material, has height reliability, the printed circuit of excellent flexibility by being etched on the Copper Foil form that circuit makes a kind of.
FPC also has good thermal diffusivity and solderability and is easy to advantages such as load, integrated cost be lower, and the design of soft or hard combination has also remedied flexible parent metal not enough slightly on the element bearing capacity to a certain extent.
Flexible print circuit board has the branch of single face, two-sided and multi-layer sheet.The base material that is adopted is based on polyimide copper clad lamination.This kind material thermal resistance height, dimensional stability are good, form 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 being electrically connected of ectonexine circuit by metallization.
Summary of the invention
The utility model has overcome the deficiencies in the prior art, and the flex cable plate FPC of a kind of cost savings, stable performance and cost savings is provided.
The technical solution adopted in the utility model is: a kind of flex cable plate FPC, comprise piece zone, coverlay, backing material plate, tack coat and reinforcement, described piece zone is arranged on the hollow out zone above the coverlay, described coverlay be arranged on backing material plate above, described reinforcement is arranged on the end below the backing material plate, and described tack coat is arranged on the other end below the backing material plate.
As preferably, described backing material plate material is a polyimide copper clad lamination, selects high-purity, structure rolled copper foil material very uniformly for use, makes its crystal orientation be parallel to line alignment, has improved the toughness of product; Before circuit is made, pass through high-temperature heat treatment simultaneously, the Copper Foil flexural property is strengthened once more, also eliminated contraction and stress that PI produces because of the moisture absorption, thereby improved bending ability effectively.
As preferably, described bonding layer material adopts acrylic resin or modified epoxy, not only salable isolated moisture and most solvent, uvioresistant and cold cycling for a long time, can on average disperse stressed, the user is used more frivolous material and is not had material deformation, problems such as metal fatigue.
As preferably, described coverlay is polyester resin film (PET), and the polyester resin film advantage is:
I can be carried out hand weldering or low melting point welding,
II has high adhesive property,
But the flexible alternating bending that III is outstanding is folding,
IV has excellent in chemical moral character and processing characteristics,
The ratio of performance to price of V the best.
As preferably, described supporting material is a polyimides.
Beneficial effect: the utility model possesses simple structure, advantage such as anti-bending, withstand voltage, heat-resisting, easy to use, high sensitivity, long service life.
Description of drawings
Accompanying drawing is the stacked graph of the utility model flex cable plate FPC.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified:
As shown in drawings: a kind of flex cable plate FPC, comprise piece zone 1, coverlay 2, backing material plate 3, tack coat 4 and reinforcement 5, described piece zone 1 is arranged on the hollow out zone above the coverlay 2, described coverlay 2 be arranged on backing material plate 3 above, described reinforcement 5 is arranged on the end below the backing material plate 3, and described tack coat 4 is arranged on the other end below the backing material plate 3.
Described backing material plate 3 materials are polyimide copper clad lamination, and described coverlay 2 materials are polyester resin film, and described tack coat 4 materials adopt acrylic resin or modified epoxy, and described reinforcement 3 materials are polyimides.
