Title:
METHOD FOR MANUFACTURING THERMALLY CONDUCTIVE SHEET BY USING LIQUID RAW MATERIAL DISCHARGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/177045
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a thermally conductive sheet by using a liquid raw material discharge device comprising a discharge opening through which a liquid thermally conductive composition is discharged to the outside, and which extends along a first center axis, and a molding cast for containing a liquid discharged material which is discharged from the discharge opening. The method comprises: a liquid raw material discharging process of moving the relative position between the discharge opening and the molding cast multiple times along a second center axis in a reciprocating manner such that a liquid discharged material which is discharged from the discharge opening is contained in the molding cast while being extended by a predetermined length along the second center axis; a molded material stabilizing process of exposing the liquid discharged material contained in the molding cast through the liquid raw material discharging process to a predetermined temperature for a predetermined period of time; a molded material hardening process of hardening the discharged material stabilized through the molded material stabilizing process, thereby acquiring a hardened molded material; and a molded material cutting process of cutting the hardened molded material hardened through the molded material hardening process in a cutting direction intersecting with the second center axis, thereby acquiring a sheet having a predetermined thickness. The present invention is advantageous in that a large-sized thermally conductive sheet can be easily manufactured without a separate pressurizing process or an attaching process, and rapid mass production is easy.
