A process for making nanocrystalline double-wrapped edges by using a roller knife

Abstract

The invention provides a process for making double-wrapped nanocrystals by using a roller knife, which can produce double-wrapped nanocrystals at the same time through one production line, and the production is fast and efficient, and the production cost is low. It uses the first roller knife to roll the nanocrystalline coil into shape, and then forms the first thermal conductive film frame above the glue-free area on the upper surface during the process of transporting the nanocrystalline semi-finished product along the roller table to complete the composite. Afterwards, the nanocrystalline semi-finished product is transported forward again, and the second thermal conductive film corresponding to the area is formed under the adhesive layer area of ​​​​the lower surface, and the composite is completed. Afterwards, the composite bottom is finally coated with a release film and washed. Cut the nanocrystalline finished release film cover film that forms the upper layer, and then roll it up.

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...
