Abstract
A tape attaching method of attaching an adhesive tape to a workpiece includes a tape attaching step of attaching the adhesive tape to the workpiece in gas having a smaller molecular weight than an average molecular weight of the atmosphere, and a gas permeating step of causing the gas remaining between the workpiece and the adhesive tape to permeate the adhesive tape to thereby be removed, after the tape attaching step is carried out.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A tape attaching method of attaching an adhesive tape to a workpiece, comprising:
a tape attaching step of attaching the adhesive tape to the workpiece in gas having a smaller molecular weight than an average molecular weight of the atmosphere; and a gas permeating step of causing the gas remaining between the workpiece and the adhesive tape to permeate the adhesive tape to thereby be removed, after the tape attaching step is carried out.
2 . The tape attaching method according to claim 1 ,
wherein, in the gas permeating step, the adhesive tape is heated.
3 . The tape attaching method according to claim 1 ,
wherein, in the gas permeating step, a pressure is applied to one of or both the workpiece and the adhesive tape in a direction in which the workpiece and the adhesive tape come in close contact with each other.
4 . The tape attaching method according to claim 1 ,
wherein the gas is helium.Join the waitlist — get patent alerts
