Description
Technical field
The present invention relates to a kind of Degumming method more particularly to a kind of methods for carrying out degumming using UV visbreaking film.
Background technique
With the rapid development of adhesive industry, visbreaking film has been widely used for semiconductor, lithium battery and all kinds of mould groups
Surface protection.UV visbreaking film is a kind of peel strength with higher when in use, can be lost rapidly after being irradiated by UV light
The special adhesive tape of vanishing viscosity plays protection and supporting role by being adhesively fixed usually in wafer material process.
In scientific research and actual production, inevitably surface residue glue and phenomena such as degumming, how efficiently, environmental protection
Ground removes it the problem of increasingly paying close attention to as people.Currently, largely removing affixed object surface residue glue and degumming in industry
Method be to be wiped the residue glue on affixed object surface using organic solvent, using organic solvent erasing residue glue exist corrode affixed object
The risks such as surface be easy to cause affixed object damaged surfaces.
In view of this, the present invention is specifically proposed.
Summary of the invention
The purpose of the present invention is to provide a kind of Degumming methods, and the Degumming method is not only easy to operate, and can efficiently,
Conveniently, the residual de- of affixed object surface is removed to low-risk, degumming effect is good, and the residual rate of residue glue is low.
Degumming method provided by the invention, includes the following steps：
A) UV visbreaking film is fitted in on degumming face；
B the UV visbreaking film) is irradiated using UV, then removes the UV visbreaking film；
Wherein, before carrying out the UV irradiation, 180 ° of peel strengths of the UV visbreaking film are 7-15N/25mm.
Degumming method of the invention is mainly used for UV glue (hereinafter referred to as residue glue) remaining to substrate surface and removes；
It to degumming face is that there is residue glue or to the surface of degumming on substrate it is understood that described.The present invention is to substrate and remaining
The composition of UV glue does not limit strictly, and substrate for example can be quad flat non-pin package (QFN), printed circuit board

Phosphine), MBF (i.e. methyl benzoylformate), photoinitiator 1173 (i.e. 2- hydroxy-2-methyl -1- phenyl -1- acetone, referred to as
) and at least one of photoinitiator 184 (i.e. 1- hydroxycyclohexyl phenyl ketone, referred to as HCPK) HMPP.
Glue-line containing above-mentioned photoinitiator can make UV visbreaking film have 180 ° of suitable peel strengths after UV irradiation,
To be easily peeled off operation.
In concrete scheme of the present invention, the dosage of the curing agent is the 0.2-0.8% of virgin rubber solid content；That is, to contain admittedly
100% meter of amount, the dosage of curing agent are the 0.2-0.8% of virgin rubber solid content.Further, the curing agent can be isocyanic acid
Ester curing agent.
Glue-line containing above-mentioned curing agent can make UV visbreaking film have 180 ° of suitable peel strengths before UV irradiation,
So as to be removed well to the residue glue on degumming face.
In the present invention, virgin rubber can commonly use the conventional constituents of this field, and virgin rubber for example can be using acrylic glue etc..
Further, it is to be appreciated that the UV visbreaking film further includes substrate layer, the material of the substrate layer is selected from polychlorostyrene second
Alkene (PVC), polyolefin (PO), ethylene-vinyl acetate copolymer (EVA) etc..
Above-mentioned substrate layer can be sufficiently bonded with being formed to degumming face well, be conducive to the removal efficiency for improving residue glue.
The present invention does not limit the thickness of each layer of UV visbreaking film strictly, wherein：The thickness of substrate layer for example can be 100
μm or so；The thickness of UV visbreaking glue-line for example can be 20 μm or so；The thickness of release film layer for example can be 38 μm or so.
In the present invention, step A) may include：
UV visbreaking film is covered in on degumming face；
To being covered with pressing to degumming face for UV visbreaking film.
Wherein, pressure mode and condition are not limited strictly, as long as UV visbreaking film can be made sufficiently to be fitted in residue glue table
Face is to be conducive to degumming, such as can be pressed using modes such as weight pressure, air pressure pressures.
The present invention does not limit the condition that UV irradiates strictly；Wherein, the exposure of the UV irradiation is greater than 200mJ/cm2
, the peel strength of UV visbreaking film can be significantly reduced, to can be removed well when removing UV visbreaking film to de-
The removal efficiency of residue glue in glue surface, residue glue is high.
In the present invention, before carrying out the UV irradiation, 180 ° of peel strengths of the UV visbreaking film are less than 1N/25mm,
Preferably 0.2N/25mm is hereinafter, further preferably 0.1N/25mm or less.
