Patent ID: 7594977

Claim:
A method for bonding a tape by which a tape member is bonded to a work piece, comprising: a sucking step at which, in a state in which said work piece is mounted on the upper surface of an elastic sheet member, and said tape member is located in a stretched state in the upper portion of said work piece by a tape holding unit, vacuum suction of a first vacuum chamber located on the side of the upper surface of said elastic sheet member is performed by a first sucking unit, and, at the same time, vacuum suction of a second vacuum chamber located on the side of the lower surface of said elastic sheet member is performed by a second sucking unit; a vacuum achievement detecting step at which it is detected that said first vacuum chamber and said second vacuum chamber have reached a predetermined degree of vacuum by said sucking step; a first air introducing step at which, after reaching the degree of vacuum predetermined by said vacuum achievement detecting step is detected, vacuum suction of said second vacuum chamber is stopped by stopping operation of said second sucking unit, and, at the same time, the air is introduced into said second vacuum chamber by operating a second air introducing unit; a bonding step at which, after said first air introducing step, said elastic sheet member is expanded toward the inside of said first vacuum chamber, said work piece is raised toward said tape member by expanding said elastic sheet member, and said work piece is bonded to said tape member; and a second air introducing step at which, after executing said bonding step for a predetermined time, the air is introduced into said first vacuum chamber by operating a first air introducing unit; and at said sucking step, when said first and said second sucking units are operated, said second sucking unit is initially operated, and then said first sucking unit is operated.
