Abstract
The utility model discloses an anti-solder tape which comprises a base material film layer, a reinforced belt and a pressure-sensitive layer. The anti-solder tape is characterized in that the reinforced belt is coated on the surface of one side of the base material film layer; and the pressure-sensitive layer is coated on the surface of the other side of the base material film layer. After the structure of the reinforced belt is combined with the base material film layer, the original single-layer base material structure is changed into a double-layer compound type structure, so that the anti-solder tape has ideal high temperature resistance, and does not contract and deform when being used at the high temperature; and the anti-solder tape is soft and good in tearability.
Description
Technical field
The utility model relates to electronic product and components and parts are made applied technical field, particularly relates to a kind of anti-welding adhesive tape.
Background technology
At present; Make in the object work flow of high temperature engineering in field at electronic product; Need to use of the protection of various adhesive tapes as covering; For example: in printed substrate being sent into tin stove wave soldering process, need to use anti-welding adhesive tape that the aperture on the printed substrate is carried out shutoff and cover protection.Existing anti-welding adhesive tape forms by applying varistor layer on the base material film layer; The adhesive band base of this structure is a single layer structure; Use this type adhesive tape to adhere on the aperture of printed substrate as covering protection, and when printed substrate sent into tin stove wave soldering, occur easily shrinking and obscission; Can cause the aperture on the printed substrate exposed, thereby cause scrapping of printed substrate.
The utility model content
The technical problem that the utility model mainly solves is: to the deficiency of prior art; A kind of anti-welding adhesive tape is provided,, makes original single layer of substrate material structure become the composite structured of bilayer through on the base material film layer, combining the reinforcing band structure; Has the ideal resistance to elevated temperatures; Do not shrink when it is at high temperature used, indeformable, and soft docile, tearable property is good.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of anti-welding adhesive tape is provided; Comprise base material film layer, reinforcing band and varistor layer; Said reinforcing band is coated in a side surface of said base material film layer, and said varistor layer is coated in the opposite side surface of said base material film layer.
In preferred embodiment of the utility model, said base material film layer is a polyimide film layer.
In preferred embodiment of the utility model, said reinforcing band is high temperature resistant wrinkle beautifying paper tape.
In preferred embodiment of the utility model, said varistor layer is the silicone glue-line.
In preferred embodiment of the utility model, the thickness of said varistor layer is 0.03-0.05mm.
The beneficial effect of the utility model is: the utility model has disclosed a kind of anti-welding adhesive tape; Through on the base material film layer, combining the reinforcing band structure; It is double-deck composite structured that original single layer of substrate material structure is become, and has the ideal resistance to elevated temperatures, do not shrink when it is at high temperature used, indeformable; And soft docile, tearable property is good.
Description of drawings
Fig. 1 is the structural representation of anti-welding adhesive tape one preferred embodiment of the utility model;
The mark of each parts is following in the accompanying drawing: 1, varistor layer, 2, the base material film layer, 3, reinforcing band.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiment of the utility model is set forth in detail, thereby the protection domain of the utility model is made more explicit defining so that advantage of the utility model and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also shown in Figure 1ly, the utility model embodiment comprises:
A kind of anti-welding adhesive tape comprises base material film layer 2, reinforcing band 3 and varistor layer 1, it is characterized in that, said reinforcing band 3 is coated in a side surface of said base material film layer 2, and said varistor layer 1 is coated in the opposite side surface of said base material film layer 2.
Said base material film layer 2 is a polyimide film layer, has outstanding high temperature resistant, radiation hardness, resistance to chemical attack and electrical insulation capability, can use in that 250-280 ℃ of air is medium-term and long-term.
Said reinforcing band 3 is high temperature resistant wrinkle beautifying paper tape, has wet tenacity or solvent resistance preferably, good temperature tolerance, barrier properties, absorptivity, elongation and tensile strength.
Said varistor layer 1 is the silicone glue-line, and its bonding force is strong, and tensile strength is big, has weathering resistance, vibration resistance simultaneously again, the moistureproof and big characteristics of the cold and hot variation of adaptation.
The thickness of said varistor layer 1 is 0.03-0.05mm.
The utility model has disclosed a kind of anti-welding adhesive tape; Through on the polyimide base material thin film layer, combining high temperature resistant U.S. line paper as the reinforcing band structure; It is double-deck composite structured that original single layer of substrate material structure is become, and has the ideal resistance to elevated temperatures, and do not shrink when it is at high temperature used, indeformable; And soft docile, tearable property is good.
The above is merely the embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model specification sheets and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
