The purpose of this study is to find out if a contactor in a mechanical input/output connector interface, using elongated plates subjected to bending, can be made sufficiently small to be utilized in an advanced VLSI package to interconnect it to the “outside world”. A design with metallic plate contactors having both ends clamped and a design with cantilever contactors are examined and analyzed. It is shown that the size of the structure is restricted by the strength of the plate material and that cantilever plates result in almost three times smaller effective length of the contactor than both-ends-clamped plates. The obtained results can be used as a guidance in physical design of mechanical input/output connectors of the type in question.
