Abstract:
1. A method for manufacturing an assembly including a printed circuit board and a plurality of tape carrier packages attached to the printed circuit board, each of the tape carrier packages having conductive leads parallel with each other, the method comprising: arranging the tape carrier packages along a common axis such that center lines of the tape carrier packages, which are substantially perpendicular to the common axis, wherein the central lines of the tape carrier package adjacent to each other are spaced apart from each other at respective first intervals; forming a plurality of land groups on the printed circuit board, the land groups comprising conductive leads respectively and being arranged along the common axis, center lines of the land groups, which are substantially perpendicular to the common axis, being spaced apart from each adjacent other at respective second intervals determined in accordance with thermal expansion properties of the printed circuit board such that, in a pre-compression bonded state, the respective second intervals are smaller than the respective first intervals; thermocompression bonding the tape carrier packages to the printed circuit board; and, during the thermocompression bonding, allowing the printed circuit board to expand such that the respective lands are substantially aligned with corresponding ones of the leads of the tape carrier packages.
