ABSTRACT:
The invention is embodied in a demountable TAB assembly. By using two springs in series, the present invention is able to maintain reliable contact between the TAB frame and the printed circuit board even if the elastomeric spring relaxes. The present invention also incorporates a novel TAB frame using contacts formed into an area-array. This area-array concept eliminated the need for fine line printed circuit board technology to support the TAB assembly.
