Abstract

The utility model relates to a two -sided FPC reinforcement protection film, including the PET substrate layer, PET substrate layer top is equipped with the fluorine membrane, is covered with gently from type silica gel layer between this fluorine membrane and the PET substrate layer, PET substrate layer below is equipped with fluorine silicon and is equipped with between type membrane and PET substrate layer heavily from type silica gel layer from type membrane, fluorine silicon. The upper strata and the lower floor of above -mentioned this membrane of two -sided FPC reinforcement protection film have different adhesion bonds, and at the in -process of flexible circuit board rendition, the in -process that is especially tearing the top layer membrane is unlikely to to play PET substrate layer area, lead to the location to be forbidden and cause the product to scrap.

Description

A kind of two-sided FPC reinforcement diaphragm

Technical field

The utility model is related to the technology field of membrane materials of electronic product, specially a kind of two-sided FPC reinforcement diaphragm.

Background technology

Flexible PCB is also known as " soft board ", i.e. FPC plates.It is the printed circuit being made of flexible insulating substrate.Flexible electrical Road provides excellent electrical property, can meet smaller and more high-density installation design needs, it helps reduce assembling procedure With enhancing reliability.Flexible PCB is the only solution for meeting miniaturization of electronic products and movement requirement.Can be free Bending, winding, folding, can bear the dynamic bendings of millions of times without damaging wire, can be any according to space layout requirement Arrange, and arbitrarily moved and flexible in three dimensions, so as to reach the integration of components and parts assembling and wire connection;Flexible circuit Plate can be substantially reduced the volume and weight of electronic product, be applicable electronic product and develop to high density, miniaturization, highly reliable direction Need.

Antistatic PET protection film applies the market prospects on " FPC " very wide, performance：Transparent anti static PET protection film is soft, with FPC plates hardness almost, and transparent to it is observed that FPC surface treatments requirement, and And electrostatic and dust will not be produced certainly yet with contacting external air.Because antistatic protection film both sides have antistatic to apply Layer, therefore electrostatic will not be produced again when being separated with FPC plates, the chip of circuit on FPC plates will not be also punctured certainly.This was both solved Electrostatic is produced FPC plates in transit, while not only can be bonded and transparent but also by the shadow of the environmental factors such as air, humidity Ring.

Utility model content

The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, there is provided a kind of two-sided FPC reinforcement Diaphragm, the upper and lower of the film have different bonding forces, during flexible PCB is transferred, are particularly tearing It is unlikely to take up PET base material layer during the film of top layer, causes positioning inaccurate and cause product rejection.

To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of two-sided FPC reinforcement diaphragm, including PET base material layer, the PET base material layer top is provided with fluorine element film, and light release silica gel is covered between fluorine element film and PET base material layer Layer；The PET base material layer lower section is provided with fluorine silicon mould release membrance, and the release silicon of weight is provided between the fluorine silicon mould release membrance and PET base material layer Glue-line.

Further improved as the utility model, the thickness of the light release layer of silica gel is 0.03mm~0.035mm, its Mass density in unit area is 0.01g/mm2.

Further improved as the utility model, the thickness of the heavy release layer of silica gel is 0.05mm~0.06mm, its Mass density in unit area is 0.005g/mm2.

Further improved as the utility model, the thickness of the fluorine silicon mould release membrance is 0.1mm~0.15mm.

Further improved as the utility model, the thickness of the fluorine element film is 0.05mm~0.055mm.

Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：

A kind of two-sided FPC reinforcement diaphragm of the utility model scheme, the upper and lower of the film have different bondings Power, during flexible PCB is transferred, is particularly unlikely to take up PET base material layer during top layer film is torn, Cause positioning inaccurate and cause product rejection.

Brief description of the drawings

Technical solutions of the utility model are described further below in conjunction with the accompanying drawings：

Accompanying drawing 1 is the structural representation of the two-sided FPC reinforcement diaphragm of the utility model.

In figure：1st, fluorine element film；2nd, light release layer of silica gel；3rd, PET base material layer；4th, the release layer of silica gel of weight；5th, fluorine silicon mould release membrance.

Specific embodiment

Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.

A kind of two-sided FPC reinforcement diaphragm as shown in Figure 1, including PET base material layer, the top of the PET base material layer 3 are provided with Fluorine element film 1, is covered with light release layer of silica gel 2 between fluorine element film 1 and PET base material layer 3；It is release that the lower section of PET base material layer 3 is provided with fluorine silicon Film 4, is provided with the release layer of silica gel 4 of weight between fluorine silicon mould release membrance 4 and PET base material layer 3.

PET base material layer 3 uses high grade of transparency PET film, is coated with acrylic acid adhesive and is made；It is various to metal, plastics etc. Clung body has suitable adhesive strength, and confining force is functional；Low viscosity, tape surface is smooth；It is water resistance, heat-resisting Property, weatherability, acid-proof alkaline are good.

The thickness of light release layer of silica gel 2 is 0.03mm~0.035mm, and the mass density in its unit area is, it is easier to be taken off from PET base material layer 3.

The thickness of the release layer of silica gel 4 of weight is 0.05mm~0.06mm, and the mass density in its unit area is

, cohesive is stronger, compared with light release layer of silica gel 2, it is not easy to taken off from PET base material layer 3.This Planting characteristic can ensure that positioning precision of the flexible PCB in transfer is unaffected, it is ensured that the quality of product.

The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model System.All use equivalents or equivalence replacement and the technical scheme that is formed, all fall within the utility model rights protection scope it It is interior.
