Abstract
The utility model discloses an LED display switching FPC which comprises a base material plate, covering films, reinforcing areas and stamping areas. The covering films are disposed on the upper side and the lower side of the base material plate. The reinforcing areas are arranged on the upper end and the lower end of the covering films. The stamping areas are arranged on the upper end and the lower end of the base material plate. The LED display switching FPC has the advantages of simple structure, bending resistance, pressure resistance, heat resistance, convenient use, high sensitivity, long service life, etc.
Description
Technical field
The utility model relates to a kind of flex circuit application and manufactures and designs, and is specifically related to LED and shows manufacturing and designing of switching FPC.
Background technology
Flexible printed circuit board (Flexible Printed Circuit Board) is the printed circuit of processing with 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 is claimed flexible circuit board again; With mylar or polyimides is base material, has height reliability, the printed circuit of excellent flexibility through being etched on the Copper Foil form that circuit processes 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 that soft or hard combines 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 main with 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 through compacting.Top layer and inner conductor two-sided, multilayer printed wiring board are realized being electrically connected of ectonexine circuit through metallization.
Summary of the invention
The utility model has overcome the deficiency of prior art, provides the LED of a kind of stable performance and cost savings to show switching FPC.
The technical scheme that the utility model adopts is: a kind of LED shows switching FPC; Comprise backing material plate, coverlay, reinforcement and piece zone; Said coverlay is arranged on the upper and lower surface of backing material plate; Said reinforcement is arranged on the two ends up and down of said coverlay, and said piece zone is arranged on the two ends up and down of backing material plate.
As preferably, said 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, said coverlay is polyimides (PI), and the polyimide 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 that V is best.
Beneficial effect: the utility model LED shows that switching FPC possesses simple structure, anti-bending, advantage such as withstand voltage, heat-resisting, easy to use, high sensitivity, life-span are long.
Description of drawings
Fig. 1 is the stacked graph that the utility model LED shows switching FPC.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
As shown in Figure 1: a kind of LED shows switching FPC; Comprise backing material plate 1, coverlay 2, reinforcement 3 and piece zone 4; Said coverlay 2 is arranged on the upper and lower surface of backing material plate 1, and said reinforcement 3 is arranged on the two ends up and down of said coverlay 2, and said piece zone 4 is arranged on the two ends up and down of backing material plate 1.
Said backing material plate 1 material is a polyimide copper clad lamination, and said coverlay 2 is a polyimide film.
Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.The all available prior art of each part not clear and definite in the present embodiment realizes.
Claims (3)
1. a LED shows switching FPC; It is characterized in that: comprise backing material plate, coverlay, reinforcement and piece zone; Said coverlay is arranged on the upper and lower surface of backing material plate, and said reinforcement is arranged on the two ends up and down of said coverlay, and said piece zone is arranged on the two ends up and down of backing material plate.
