Membrane module.
In order to solve the above-mentioned technical problem, technical solution provided by the utility model are as follows:
It is a kind of to cut isolated pad pasting component for DFN/QFN encapsulation, including workbench and it is arranged on the table
Steel ring and pad pasting disk, the steel ring are located at the periphery of pad pasting disk, and it is solid that the pad pasting disk is equipped with sucker, the first fixed area and second
Determine area, the sucker is arranged on the first fixed area and the second fixed area, and first fixed area and the second fixed area are closed on and set
It sets.
Wherein, the spacing of first fixed area and the second fixed area is 20mm.
Wherein, the surrounding of first fixed area and the second fixed area is equipped with positive stop lug boss, the width of the positive stop lug boss
It is 0.3mm for 2mm, interior depth, outer a height of 0.5mm.
Wherein, the length of the pad pasting disk and wide respectively 290mm and 214mm.
Wherein, the length of the steel ring and wide respectively 340mm and 268mm.
Wherein, the steel ring is equipped with limited step, and the workbench is equipped with for matching determining for the limited step
Position pin.
Wherein, the quantity of the sucker is eight, is divided into two groups, is separately positioned on the first fixed area and second and fixes
Qu Shang.
Wherein, the groove for cutting membrane material is additionally provided on the workbench.
The utility model has the following beneficial effects: since first fixed area of the utility model and the second fixed area are closed on and are set
It sets, by the spacing for reducing the first fixed area and the second fixed area, it is possible to reduce the area of pad pasting disk and steel ring.By DFN/QFN
The product of encapsulation, which is fixed on steel ring, to be needed, since the area of steel ring reduces, to correspondingly reduce the use of UV film using UV film
Amount, to reduce costs.By test, the utility model can reduce by 1/3 UV film dosage.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As the embodiment described in the utility model for cutting isolated pad pasting component for DFN/QFN encapsulation, such as Fig. 1 institute
Show, including workbench 1 and the steel ring being arranged on workbench 12 and pad pasting disk 3, the steel ring 2 is located at the periphery of pad pasting disk 3,
The pad pasting disk 3 is equipped with sucker 31, the first fixed area 32 and the second fixed area 33, and the sucker 31 is arranged in the first fixed area
32 and second on fixed area 33, and first fixed area 32 and the second fixed area 33 close on setting.
Since first fixed area 32 of the utility model and the second fixed area 33 close on setting, by reducing by the first fixed area
32 and second fixed area 33 spacing, it is possible to reduce the area of pad pasting disk 3 and steel ring 2.The DFN/QFN product encapsulated is fixed to
It needs, since the area of steel ring 2 reduces, the dosage of UV film to be correspondingly reduced, to reduce into using UV film on steel ring 2
This.By test, the utility model can reduce by 1/3 UV film dosage.It, can be by DFN/QFN by the adsorption capacity of sucker 31
The product of encapsulation is fixed firmly on the first fixed area 32 and the second fixed area 33, and UV film is made entirely to fit to DFN/QFN
On the product of encapsulation, to improve the yields of pad pasting.
In the present embodiment, the spacing of first fixed area 32 and the second fixed area 33 is 20mm.By test, cutting
During cutting, the safe spacing of the product of monolithic DFN/QFN encapsulation is in 20mm or more, by reducing by the first fixed area 32 and second
