1. A method of making a microelectronic assembly comprising:
- (a) juxtaposing a first element having conductive leads thereon with a second element having contacts thereon;
(b) wire bonding the conductive leads on the first element to the contacts on the second element so that elongated bonding wires extend between said conductive leads and said contacts;
(c) after said wire bonding step, moving the first and second elements through a preselected displacement relative to one another so as to deform the bonding wires.

Abstract
A method of making a microelectronic assembly includes juxtaposing a first element having conductive leads thereon with a second element having contacts thereon, and wire bonding the conductive leads on the first element to the contacts on the second element so that elongated bonding wires extend between the conductive leads and the contacts. After the wire bonding step, the first and second elements are moved through a preselected displacement relative to one another so as to deform the bonding wires.

28. A method of making a microelectronic assembly comprising:
-
(a) juxtaposing a first element with a second element so that said first element is disposed above said second element;
(b) providing leads extending between said elements, said leads being curved in a vertical direction, said leads including loop portions projecting upwardly from said dielectric sheet;
(c) after providing said leads, moving the first and second elements through a preselected displacement relative to one another so as to deform the leads, wherein said loop portions are pulled toward said dielectric sheet during said moving step. - View Dependent Claims (29, 30, 31, 32)

46. A method of making a microelectronic assembly comprising:
-
providing a first microelectronic element including a top surface having leads with fixed ends and releasable ends, the top surface of the first microelectronic element having contacts;
juxtaposing a second microelectronic element having contacts on a contact bearing face and a rear surface with the first microelectronic element so that the contact bearing face confronts the top surface of said first microelectronic element;
attaching the contacts of said second microelectronic element with the releasable ends of the leads of the first microelectronic element;
juxtaposing a third microelectronic element having a contact bearing face and a rear surface with the rear surface of said second microelectronic element so that the rear surfaces of said first and second microelectronic elements confront one another and the contacts of the third element face away from the first microelectronic element;
wire bonding the contacts of the third microelectronic element with the contacts of the connection component;
moving said second and third microelectronic elements away from said first microelectronic element so as to deform the bonding wires. - View Dependent Claims (47)
