Description
Technical field
The present invention relates to the hot soarfing for electronic component from pressure sensitive adhesion sheet, more particularly to provide a kind of heat for producing coating
The process of stripping tape, more particularly to provides the early pre-treatment process of microspheres.
Background technology
Hot soarfing from pressure sensitive adhesion sheet electronic component process, in the cutting of such as semi-conducting material, grinding technique
Temporarily fixed effect is played, by the way that machined object is fixed on processing equipment, is smoothed out processing, can after the completion of technique
Pressure-sensitive adhesive sheet is set to depart from machined object without causing damage to pollute by way of heating.
However, because microspheres quality differs, generally speaking, the smaller quality of microspherulite diameter preferably, some particle diameters compared with
There is microballoon rupture or poor sealing phenomenon in big microballoon.It can be swelled or solvent after second-rate micro-sphere contacts solvent
Into the phenomenon of microballoon inwall so that microspherulite diameter substantially becomes big, and pressure causes the rupture of foam microspheres to produce bubble during overlay film.
Cause to be coated on the glued membrane on base material and there is surface and occur uneven and have a bubble phenomenon, reduce bonding force, although surface
It is coarse not influence the heat release performance of glued membrane, but the presence of bubble makes its stripping fluctuation larger.
The content of the invention
In view of the defect that above-mentioned prior art is present, locates in advance it is an object of the invention to provide a kind of early stage of microspheres
Science and engineering skill, by adjusting the parameters such as the solid content of adhesive, the quality of microspheres and coating thickness, prepares surface bubble-free
And the good glued membrane of planarization, to solve to reduce bonding force due to microspheres rupture generation bubble and influence asking for peeling force
Topic.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of hot soarfing is from pressure sensitive adhesion sheet, successively including substrate layer, thermally expandable layer, release film layer, the heat-swellable

Further, the weight ratio of the microspheres and the bonding agent is (1 ︰ 100)-(1 ︰ 1), is preferably (1 ︰
100)-(1 ︰ 2).
It is a kind of to prepare method of the hot soarfing from pressure sensitive adhesion sheet, i.e., the microspheres are pre-processed, pre- place
The step of reason is：The microspheres are uniformly mixed with polar solvent 0.1-0.4 in mass ratio, used after standing 5-10min
Filter screen filtration, then the microspheres are separated, slough surface solvent with filter paper with the polar solvent, obtain pre- place
The microspheres after reason.
Further, the polar solvent is one or both of toluene, ethyl acetate.
Further, the mesh number of the screen pack is the mesh of 200 mesh -400.
Compared with prior art, the beneficial effects of the invention are as follows：After being pre-processed to microspheres with polar solvent,
The generation that can prevent from being swelled after contacting with solvent type adhesive etc., it is to avoid occur rupture because of pressure during overlay film and produce bubble, from
And surface bubble-free and the good glued membrane of planarization are prepared, bonding force of the hot soarfing from pressure sensitive adhesion sheet is improved, reduces the ripple of peeling force
It is dynamic.
