Test system having alignment member for aligning semiconductor components

摘要

A test system for testing semiconductor components includes an interconnect having contacts for making temporary electrical connections with terminal contacts on the components. The interconnect contacts can be configured to electrically engage planar terminal contacts (e.g., bond pads, test pads) or bumped terminal contacts (e.g., solder bumps, solder balls) on the components. The test system also includes an alignment member for aligning the components to the interconnect. Different embodiments of the alignment member include: a curable polymer material molded in place on the interconnect; an alignment opening formed as an etched pocket in a substrate of the interconnect; and a separate fence attached to the interconnect using an alignment fixture.
