  • Patent number: 11512411
    Abstract: A PTFE sheet in which PTFE fibers having a diameter of 1 ?m or less are spun, the PTFE sheet having a Gurley value in the range of 1 s/100 cc/in2 to 3 s/100 cc/in2 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 makes a die adsorbable via a tool, which is for heating the die when the die is mounted on a mounting body, by being sandwiched between the die and the tool, and suppresses the adhesion, to an adsorption surface of the tool or to the die, of an adhesion member for fixing the die to the mounted body. Through this configuration, a PTFE sheet capable of stabilizing vacuum adsorption and improving maintainability and a method for mounting a die are provided.
