Abstract:
A method of making a microelectronic unit comprising:(a) providing a grid formed from a flexible, electrically conductive material, said grid having a bottom surface and a top surface, said grid including a plurality of elongated leads each having a first end and a second end, and frangible elements connecting the first ends of at least some of said leads to the second ends of others of said leads;(b) placing said grid between a top element and a bottom element so that said top surface of the grid faces toward the top element and the bottom surface of the grid faces toward the bottom element;(c) bonding said first ends of said leads to said top element but not said bottom element and the second ends of said leads to the bottom element but not the top element; and then(d) moving said top and bottom elements with a vertical component of motion away from one another so that the first ends of said leads move upwardly with respect to the second ends of said leads, whereby said frangible elements are broken and said leads are deformed to a vertically-extensive disposition.
