Description

Technical Field

[0001] The utility model relates to the technical field of IC packaging, in particular to a glue supply mechanism which is convenient for cleaning residual glue. Background Art

[0002] During the IC packaging process, an electronic protective film is usually required to position and protect IC components, wherein the UV anti-adhesion film comprises a substrate layer, a glue layer and a release film layer stacked in sequence, and the glue layer is prepared by spraying glue on the substrate layer.

As the condensation layer becomes thicker and thicker, it is difficult to remove, which eventually causes the nozzle to be blocked, reducing the service life of the nozzle. Therefore, a glue supply mechanism that is easy to clean the residual glue is proposed to solve the above-mentioned problem. Utility Model Content
