This article describes a scheme for increasing the available signal I/O capability of pluggable MLC (multilayer ceramic) circuit modules by bringing the power distribution network to the module through a unique top-cap connection structure. Selective metallization of the outer sides of the ceramic cap structure is employed in conjunction with a system of spring contacts to provide a three-dimensional power connection and distribution system to the module. While the example illustrated in this article applies specifically to a pluggable MLC multi-chip module (MCM), the disclosed interconnection structure (which offers significant cost savings and is readily implementable) applies equally to metallized ceramic (MC) and glass-ceramic pluggable/solderable module structures.
