The invention claimed is: 1. A method of making a microelectronic assembly, comprising: a) juxtaposing a microelectronic component, comprising: 1) a dielectric layer defining at least one opening; and 2) a plurality of leads attached to the dielectric layer so as to extend across the at least one opening, each of the leads having a first end portion on a first side of the opening and a second end portion on a second side of the opening, said first end portion and second end portion defining an axis, each of the leads having an offset portion disposed in the at least one opening and offset from the axis, and a microelectronic element with one another; and b) connecting each of the leads to a contact on the microelectronic element, including forcing the offset portion of the lead downwardly into engagement with the contact. 2. The method of claim 1, wherein the microelectronic component and microelectronic element are juxtaposed with one another so that each of the contacts lie beneath the axis of one of the leads. 3. The method of claim 1, wherein the microelectronic component and microelectronic element are juxtaposed so that the leads overlie a first face of the microelectronic element, the contacts being exposed at the first face. 4. The method of claim 1, wherein the step of connecting includes forming at least one twisted portion of each lead. 5. The method of claim 4, wherein the step of connecting includes moving the offset portion, wherein the dielectric layer extends in a plane, and the offset portion is moved out of the plane of the dielectric layer. 6. The method of claim 5, wherein the first end portion and second end portion is disposed at the plane of the dielectric layer and remain at the plane of the dielectric layer during the step of connecting. 7. The method of claim 1, wherein the first end portion and the second end portion are retained by the dielectric layer during the step of connecting. 8. The method of claim 1, wherein the step of connecting includes engaging the offset portions of the leads with a bonding tool.
