Elastomeric connectors for electronic packaging and testing
First Claim
1. An elastomeric connector for connecting at least one input/output pad of a first electrical component located on the first surface of said elastomeric connector to at least one corresponding input/output pad of a second electrical component located on the second surface of said elastomeric connector comprising:
- an elastomeric base,at least one substantially linear through-hole conductor extending from said first surface of said elastomeric base to said second surface,at least one surface conductor tab located on said first surface of said elastomeric base, said surface conductor tab being connected to said substantially linear through-hole conductor at said first surface of said elastomeric base, said surface conductor tab having an overhanging contact region extending past the periphery of said through-hole conductor,said substantially linear through-hole conductor remains stationary while said first electrical component is urged against said overhanging contact region,said overhanging contact region being substantially parallel to said first surface of said elastomeric base is aligned with input/output pad of said first electrical component mounted on said first surface of said elastomeric connector; and
said substantially linear through-hole conductor at said second surface of said elastomeric base being aligned with said input/output pad of said second electrical component located on said second surface of said elastomeric base to make direct surface engagement therewith.

Abstract
An elastomeric connector for permanently or temporarily (for testing purposes) connecting area array chips without solder balls or wire bonds comprising an elastomer base material having through-hole conductors deposited therein, and surface conductor tabs which are electrically connected to the through-hole conductors deposited thereon. The surface conductor tabs have an overhanging contact region extending past the periphery of the through-hole conductors. Upon contact between the input/output pads of a chip and the overhanging contact regions of the elastomeric connector when aligned and biased towards each other, a requisite pressure causes a reactionary force by the elastomer base which facilites contact and automatic wipe. The elastomeric connectors may replace solder balls in chip connection applications, or may replace buckling beam test probe heads in chip test applications.
