Printed circuit board including pads with vacancies

摘要

Methods and apparatuses for affecting the frequency behavior of connections within a printed circuit board or an integrated circuit are disclosed. Some embodiments include a printed circuit board comprising, a plurality of conductive layers each comprising at least one conductive pad, where each conductive pad on the conductive layers includes a vacancy, and an insulating material disposed about the conductive layers such that the vacancies are at least partially filled with the insulating material.
