Title:
CREEP-PREVENTING PTFE SHEET USED FOR DIE MOUNTING, AND METHOD FOR MOUNTING DIE
Document Type and Number:
WIPO Patent Application WO/2019/107419
Kind Code:
A1
Abstract:
A PTFE sheet (44) spun from PTFE fibers having a diameter of no more than 1 μm, the PTFE sheet (44) having a Gurley value in the range of 1 to 3 and a shrinkage factor in a direction orthogonal to a sheet winding direction of no more than 10% when heated to 300 °C. The PTFE sheet (44) makes a die (100) adsorbable via a tool (22), which is for heating the die (100) when the die (100) is mounted on a mounted body (110), by being sandwiched between the die (100) and the tool (22), and suppresses the adhesion, to an adsorption surface (24) of the tool (22) or to the die (100), of an adhesion member (114) for fixing the die (100) to the mounted body (110). Through this configuration, a PTFE sheet capable of stabilizing vacuum adsorption and improving maintainability and a method for mounting a die are provided.
