Tape-like member transfer system

Abstract

A tape-like member or TAB tape transfer system formed of a thin film tape is transferred without being flexible in the width direction thereof. A tape-like member transfer system comprises a TAB tape having conductive patterns formed thereon along the longitudinal direction and mounting semiconductor chips thereon, transfer roller pairs for transferring the TAB tape while putting it therebetween and a test device provided on the midway of transfer of the TAB tape, wherein the transfer roller pairs are arranged on both end sides of the TAB tape in the width direction, and when an amount of binding of the TAB tape which protrudes upward and substantially perpendicular to the transfer surface of the TAB tape is detected by a detection sensor while the TAB tape is transferred, axes of rotation of the driving rollers of the transfer roller pairs are inclined at a given angle by a control motor so as to apply right and left tensile forces to the TAB tape in the width direction so that the TAB tape is transferred without being bent.
