Description
Technical field
The utility model relates to composite plastic film, particularly the three-in-one composite buffering release film of one.
Background technology
Along with the development of information, printed substrate is to little conveniently the developing of short and small matter, therefore there is design and the requirement of Rigid Flex, thus in the printed substrate processing procedure of soft or hard combination, usually needed Copper Foil, substrate or multi-disc PP single layer structure to be pressed into sandwich construction.In the process of pressing, in order on hard and flexible circuit board, intermediate flow material be utilized to fill the concaveconvex structure on printed substrate by pressure uniformly.The materials such as this intermediate material is generally high temperature meltable plastic material, such as PE (POLYETHYLENE, polyethylene, PET).After these heating materials, usually can remain on circuit boards, pollute plate face.The composite plastic film etc. of a kind of three-in-one pressed method (machinery such as heat fusion and mechanical punching) mode structure can be adopted in the market to avoid plate surface pollution.Two-layer is up and down PET release film, and intermediate layer is PE film, is adhesion area to reduce the shade position when lamination, is bonded together by the mode of bonding, flows out and pollute plate face after avoiding middle PE film to heat.But actual service condition, the physical structure of the materials such as PET, PE release film can be destroyed due to compacting, cause the easy gauffer of PET release film, affect circuit board pressing quality, and pressing structure can make the materials such as PET, PE release film wear out, the padded coaming gummosis such as part PE can be worn out position by compacting and flow out, pollute wiring board and the wiring board tool of production, thus make producer need to spend extra flow and method and cost remove PE, PET padded coaming isocolloid material that is residual or that damage and increase cost.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of three-in-one composite buffering release film.
The utility model solves the technical scheme that its technical problem adopts: the three-in-one composite buffering release film of described one, comprise: two-layer release film, clip the PE plastic film between two-layer release film, described release film and described PE plastic film one side are provided with pastes district, described stickup district is provided with paste, described stickup district and described PE plastic film fit, described paste connects PE plastic film edge, described paste connects PE plastic film two opposite side places, described paste is spaced at pastes district, namely be in communication with the outside between release film and PE plastic film, described paste is double faced adhesive tape, glue any one, described paste is double faced adhesive tape, glue any one.
Above-mentioned being designed middlely makes original pressing mode into bonding method, release film is effectively prevented to be pierced, the PE of melting is in use avoided to pollute circuit board, and bonding method is applicable to small-scale manual production and prevents gauffer, paste is distributed in opposite side and is spaced the air being all convenient to discharge when producing between release film and PE plastic film, prevents gauffer and release film to be bursting at the collision.Described double faced adhesive tape is convenient to hand paste during small-scale production, and glue is convenient to automated production.
As the better improvement of the design, described glue is Instant cement.Described Instant cement curing rate is fast, drastically increases operating efficiency; Bonding force is strong, low viscosity, high strength, the bonding bubble-free of large area, is easy to cleaning, meets bonding requirements.
The beneficial effects of the utility model are: the utility model makes original pressing mode into bonding method, effectively prevent release film to be pierced, and avoid the PE of melting in use to pollute circuit board, and bonding method are applicable to small-scale manual production and prevent gauffer.

Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 is that paste of the present utility model connects PE plastic film two opposite side place schematic diagrames;
Fig. 3 is that paste of the present utility model is spaced at stickup district schematic diagram.
1. release films in the drawings, 2.PE plastic film, 3. paste, 4. paste district.
Embodiment
The utility model is described in detail, illustrative examples wherein and illustrate and be only used for explaining the utility model below in conjunction with accompanying drawing and specific embodiment, but not as to restriction of the present utility model.
Embodiment 1: as shown in the figure, the three-in-one composite buffering release film 1 of described one, comprise: two-layer release film 1, clip the PE plastic film 2 between two-layer release film 1, described release film 1 and described PE plastic film 2 are fitted simultaneously to be provided with and are pasted district 4, described stickup district 4 is provided with paste 3, described stickup district 4 fits with described PE plastic film 2, described paste 3 connects PE plastic film 2 edge, described paste 3 connects PE plastic film 2 two opposite side places, described paste 3 is spaced at pastes district 4, namely be in communication with the outside between release film 1 and PE plastic film 2, described paste 3 is double faced adhesive tape, glue any one, described paste 3 is double faced adhesive tape, glue any one.
Above-mentioned being designed middlely makes original pressing mode into bonding method, release film 1 is effectively prevented to be pierced, the PE of melting is in use avoided to pollute circuit board, and bonding method is applicable to small-scale manual production and prevents gauffer, paste 3 is distributed in opposite side and is spaced the air being all convenient to discharge when producing between release film 1 and PE plastic film 2, prevents gauffer and release film 1 to be bursting at the collision.Described double faced adhesive tape is convenient to hand paste during small-scale production, and glue is convenient to automated production.
As the better improvement of the design, described glue is Instant cement.Described Instant cement curing rate is fast, drastically increases operating efficiency; Bonding force is strong, low viscosity, high strength, the bonding bubble-free of large area, is easy to cleaning, meets bonding requirements.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
