APPARATUS FOR BONDING ACF

摘要

PROBLEM TO BE SOLVED: To provide an apparatus for controlling a tension to be applied to an ACF (anisotropic conductive film) without using a mechanical tension control system when the ACF is bonded to a display substrate or a printed board. SOLUTION: The apparatus 1 for bonding an ACF includes a supply reel 2 on which an ACF tape 110 is wound, and a recovery reel 4 for winding up a base tape 108, and further includes a tension motor 27 and a control unit 37. The tension motor 27 is attached to the supply reel 2, and applies a torque to the supply reel 2 in a direction N opposite to the winding direction M of the recovery roll 4. The control unit 37 controls the torque of the tension motor 27 based on the diameter D of the ACF tape 110 wound on the supply reel 2. COPYRIGHT: (C)2011,JPO&INPIT
