Techniques for controlling coupling between a motherboard and a daughter card

摘要

An improved interconnection assembly is configured to couple to only one of a first daughter card having a first arrangement of connectors and a second daughter card having a second arrangement of connectors. The interconnection assembly includes a motherboard and motherboard connectors. The motherboard connectors are adapted to couple to one of the first arrangement of connectors of the first daughter card and the second arrangement of connectors of the second daughter card. The interconnection assembly further includes a stopper attached to the motherboard. The stopper is adapted to provide interference against the other of the first arrangement of connectors of the first daughter card and the second arrangement of connectors of the second daughter card to prevent the motherboard connectors from contacting the other of the first arrangement of connectors of the first daughter card and the second arrangement of connectors of the second daughter card.
