Abstract:
A method for fabricating a connector for interconnecting the substrates of Etched Tri-Metal circuit structures comprising the steps of:a. securing a first tri-metal layer material having a first metal with parallel broadside surfaces overlaid on each broadside with a second metal layer, said second metal layer bonded to said first metal; b. disposing etch-resist masks on the exposed surface of each second metal layer defining first and second circuit patterns including at least one pedestal pattern; c. etching said second metal layer forming said first and second circuit patterns and exposing said first metal free of circuit patterns; d. bonding one of the second metal layers to a substrate; e. etching the first metal in areas free of circuit patterns to form one or more pedestal patterns on the first circuit; f. securing a second tri-metal layer material and performing the aforementioned steps a-e on the second tri-metal material; g. spreading a bonding material on one of the first circuit pattern for joining the pedestal patterns on each substrate in an interlocking manner; h. meshing the first and second substrates in such a manner that the bonding material flows about and around the pedestal patterns on each of the first and second substrates; and then i. activating the bonding material forming a bond between the pedestal patterns of the first and second substrates.
