High-speed interposer connectors that may be space-efficient, reliable, and may be readily manufactured. One example may provide an interposer connector that may be particularly space-efficient in a vertical direction by using an interposer to form an electrical connection between conductors and a main-logic board or other appropriate substrate. Another example may provide a reliable connection between conductors and a main-logic board by using fasteners to fix an interposer to the main-logic board. Another example may provide connectors that are well-suited to handling high-speed signals by providing a shield to at least partially cover a top of an interposer connector.
