Abstract
The utility model discloses a protective film for an electronic element. The protective film comprises a polyethylene base material film, the lower surface of the polyethylene base material film is coated with a pressure-sensitive viscose layer, the other surface of the pressure-sensitive viscose layer is coated with a release material layer, a plurality of thermal expansion microspheres are uniformly distributed in the pressure-sensitive viscose layer, the diameter of the thermal expansion microsphere is 9-15 micrometers, a plurality of salient points are arranged on the contact surface between the pressure-sensitive viscose layer and the release material layer, and the release material layer is a release paper layer or a release film layer. The protective film for the electronic element has better stickness at the low temperature, the stickness disappears at the high temperature, so that the small electronic element is effectively recycled, and the damage to the element is avoided.
Description
Technical field
The utility model relates to a kind of protective membrane, relates in particular to a kind of electronic devices and components protective membrane.
Background technology
In recent years, along with electronic devices and components miniaturization, it is produced and is processed and the aspect such as enhance productivity exists larger problem, particularly efficiently and the method for without damage miniature electric components and parts being peeled off to recovery be very large problem.Therefore, how to peel off protection pad pasting, effectively reclaim miniature electric components and parts, become the direction that those of ordinary skill in the art make great efforts.
Summary of the invention
The utility model provides a kind of electronic devices and components protective membrane, and these electronic devices and components have good viscosity during with protective membrane low temperature, thereby adhesiveproperties disappears and effectively reclaims miniature electric components and parts when high temperature, avoids the damage to device.
For achieving the above object, the technical solution adopted in the utility model is: a kind of electronic devices and components protective membrane, comprise polyethylene base material film, this polyethylene base material film lower surface is coated with a pressure sensitive adhesive layer, and another surface label of this pressure-sensitive adhesive layer is covered with separated type material layer; In described pressure-sensitive adhesive layer, be evenly distributed with some microspheres, the diameter of this microspheres is 9～15 microns.
In technique scheme, further improved technical scheme is as follows:
1,, in such scheme, the contact surface of described pressure-sensitive adhesive layer and separated type material layer has several salient points.
2,, in such scheme, described separated type material layer is off-style paper layer or release film layer.
3,, in such scheme, described pressure sensitive adhesive layer is esters of acrylic acid adhesive layer or organosilicon tack coat.
Because technique scheme is used, the utility model compared with prior art has following advantages:
1, the utility model electronic devices and components protective membrane; in pressure-sensitive adhesive layer, be evenly distributed with some microspheres; the diameter of this microspheres is 9～15 microns; make prepared pressure-sensitive adhesive tape when lower than 60 DEG C; there is good viscosity; toast after 5 minutes higher than 110 DEG C when temperature, this pressure sensitive adhesive loses adhesiveproperties.This pressure sensitive adhesive changes the viscosity size variation of sealing tape by temperature variation interval, possess splendid binding property and thermally strippable, has good application prospect at electronic unit manufacturing process, the aspect such as temporary fixed.
2, the utility model electronic devices and components protective membrane, can solve the bubble producing in laminating process.
