  • Patent number: 9978702
    Abstract: The present invention relates to a method and an apparatus for a resurfaceable contact pad that uses an epoxy to encapsulate contact pads so that the epoxy and encapsulated contact pads are coplanar on a silicon redistribution interposer. These redistribution interposers electrically connect a wafer semi-conductor to a probe card where it is necessary to convert the course pad arrangement of one with a fine pad arrangement of the other through the use of an interposer board. The present invention relates to an apparatus and a method creates resurfaceable contact pads which may be resurfaced one or multiple times with an abrasive sanding operation to recreate a coplanar surface should any contact pad surfaces become damaged, allowing for a more cost-effective repair.
