Abstract
The flexible tape carrier package of an LCD module is selectively reinforced so as to reduce damage in the conductive leads thereof when a microelectronic substrate such as a printed circuit board is suspended from an LCD panel by the tape carrier package. The flexible tape carrier package is preferably selectively reinforced by integrating at least two of the conductive leads along at least one selected portion of the tape carrier package between the first and second end portions thereof. Accordingly, by selectively reinforcing the flexible tape carrier package, fracturing and/or cracking of the conductive lines during LCD module manufacture and transport may be reduced.
