Process for manufacturing nanocrystal double wrapping edges by using roller knifes

Abstract

The invention provides a process for manufacturing nanocrystal double wrapping edges by using roller knifes, and the process can produce nanocrystals simultaneously with producing of nanocrystal double wrapping edges, and has the advantages of fast and efficient production and low manufacturing cost. The process comprises the following steps: rolling and cutting a nanocrystal roll for molding by afirst roller knife; forming a first thermal conductive film frame above a glue-free area on the upper surface of a nanocrystal semi-finished product in the process of conveying the nanocrystal semi-finished product along a roller way, and completing compounding; forming a second thermal conductive film, corresponding to a region, below a glue layer area on the lower surface of the nanocrystal semi-finished product by conveying the nanocrystal semi-finished product forwards again, and completing compounding; and compounding a bottom final coating release film by conveying the nanocrystal semi-finished product forwards, punching to form an upper layer nanocrystal finished product release film cover film, and then winding.

Description

technical field [0001] The invention relates to the technical field of module product assembly, in particular to a process for making nanocrystalline double-wrapped edges by using a roller knife. Background technique [0002] In the existing nanocrystal production process, since one side of the nanocrystal is used to contact the fpc as a non-adhesive surface, and the other side needs to be coated with a heat-conducting film layer as the adhesive-backed surface, in the actual process, since only one side is covered with heat conduction The film layer, which makes the outer edge of the nanometer surface used to connect with the FPC, is uneven, and some rough metal particles are exposed, and the appearance quality of the product is poor, so it needs to be coated on the periphery of the non-adhesive surface area of ​​the nanocrystalline product The profiling heat conduction layer ensures the appearance quality of nanocrystals; the existing double-encapsulation process needs to m...
