Jig for nitrogen dispergator

Abstract

The utility model discloses a jig used for a nitrogen dispergation machine, which comprises a jig body, a central dispergation opening is arranged at the center of the jig body, the central dispergation opening is matched with an iron ring, the iron ring covers the outer edge of the central dispergation opening on the jig body, and a plurality of local dispergation holes are uniformly arranged in the coverage area of the iron ring on the outer edge of the central dispergation opening on the jig body. And the UV film can be conveniently taken down from the iron ring in the later period due to the arrangement of the local peptizing holes. The arrangement of the central peptizing opening facilitates the fixation of the position of an iron ring during peptizing and ensures the peptizing of a product and a UV film, and meanwhile, the arrangement of the local peptizing hole enables partial irradiation to the joint of the UV film and the iron ring for peptizing, so that the UV film can be conveniently taken down from the iron ring in the later period, and the working efficiency is improved; the problem that when no jig exists, the glass platform makes direct contact with the UV film, so that the product is prone to plane residual glue, and the yield is low is solved, and the yield of the product is improved.

Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor component processing, in particular to a fixture used in a nitrogen disintegrator. Background Art

[0002] In the semiconductor chip production process, before the chip is diced, the wafer must be fixed on the iron ring with a dicing UV film. After the dicing process is completed, the fixing film is irradiated with UV light to reduce the viscosity of the dicing fixing film to facilitate the smooth production of the subsequent packaging process.

[0003] After the dicing process is completed, the iron ring, UV film and product that are adhered together are directly placed on the glass platform of the nitrogen dissolving machine. The nitrogen dissolving machine in the prior art mostly uses UV mercury lamp to irradiate from the bottom of the stationary workpiece to dissolve the UV film. This requires placing the UV film downward and the iron ring upward to dissolve the iron ring, UV film and product. The glass platform is in direct contact with the UV film, which is easy to leave residual glue on the glass platform, affecting the UV mercury lamp's irradiation of the UV film dissolving, making the product prone to flat residual glue, resulting in low yield. At the same time, the operator needs to frequently deal with the residual glue on the glass platform, which is inconvenient for the operator to operate. Utility Model Content

[0004] In order to solve the above technical problems, the utility model designs a fixture for use in a nitrogen dissolving machine.

[0005] The utility model adopts the following technical solutions:

[0006] A fixture for a nitrogen dissolving machine includes a fixture body, a central dissolving opening is provided at the center of the fixture body, the central dissolving opening cooperates with an iron ring, the iron ring covers the outer edge of the central dissolving opening on the fixture body, and multiple local dissolving holes are evenly provided in the iron ring-covered area at the outer edge of the central dissolving opening on the fixture body. The local dissolving holes facilitate the removal of the UV film from the iron ring in the later stage.

[0007] Preferably, the central degumming port is a directional hole.

[0008] Preferably, the local degumming hole is a circular hole.

[0009] Preferably, an iron ring removal pick is provided in the iron ring covering area outside the central glue dissolving opening on the jig body, so as to facilitate the removal of the iron ring from the jig body.

[0010] Preferably, the fixture body is made of stainless steel plate or aluminum plate.

[0011] The beneficial effects of the utility model are as follows: (1) the utility model designs a fixture for use in a nitrogen dissolving machine, which solves the problem of fixing the position of an iron ring during dissolving and improves work efficiency; (2) it solves the problem of direct contact between a glass platform and a UV film when there is no fixture, which makes it easy for the product to have residual adhesive on a flat surface, resulting in a low yield, thereby improving the yield of the product.

[0015] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0016] Example: Figure 1 and Figure 2 As shown, a fixture for a nitrogen dissolving machine includes a fixture body 1, a central dissolving opening 2 is opened in the center of the fixture body, the central dissolving opening cooperates with an iron ring 5, the iron ring covers the outer edge of the central dissolving opening on the fixture body, and multiple local dissolving holes 3 are evenly opened in the iron ring covering area on the outer edge of the central dissolving opening on the fixture body. The central dissolving opening is a directional hole. The local dissolving hole is a circular hole. An iron ring removal paddle 4 is arranged in the iron ring covering area on the outer edge of the central dissolving opening on the fixture body. The fixture body is made of stainless steel plate or aluminum plate.

[0017] The utility model designs a fixture for a nitrogen dissolving machine. The setting of a central dissolving port facilitates the fixation of the iron ring position during dissolving, ensuring the dissolving of the product 7 and the UV film 6. At the same time, a local dissolving hole is provided to partially irradiate the joint between the UV film and the iron ring for dissolving, making it convenient to remove the UV film from the iron ring later and improving work efficiency. The utility model solves the problem that the glass platform is in direct contact with the UV film when there is no fixture, causing the product to easily have planar residual glue and resulting in a low yield, thereby improving the yield of the product.

[0018] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
