摘要:
A method of manufacturing a substrate for a probe card assembly comprises preparing an interconnection layer, preparing a resin layer and preparing a base layer. The method comprises attaching the resin layer to the interconnection layer by a first thermal process at a first temperature. The method comprises attaching the resin layer attached to the interconnection layer to the base layer by a second thermal process at a second temperature higher than the first temperature.
摘要:
A substrate is provided for a probe card assembly. The substrate includes an interconnection layer including a first surface having a first electrode set and a second surface having a second electrode set electrically connected to the first electrode set. The substrate further includes a base layer including a first surface having a third electrode set electrically connected to the second electrode set and a second surface having a plurality of contact terminals electrically connected to the third electrode set. And the substrate further includes a resin layer including a plurality of sublayers made of different materials. The resin layer is attached to the first surface of the base layer and the second surface of the interconnection layer.
