SYSTEMS AND METHODS FOR FREQUENCY SHIFTING RESONANCE OF AN UNUSED VIA IN A PRINTED CIRCUIT BOARD

摘要

In accordance with embodiments of the present disclosure, a circuit board may include a first trace formed in a first layer of the circuit board, a second trace formed in a second layer of the circuit board, a via, and a termination pad. The via may be configured to electrically couple the first trace to the second trace, the via comprising a via stub corresponding to a first portion of a length of the via not within a second portion of the via between a first location in which the first trace is electrically coupled to the via and a second location in which the second trace is electrically coupled to the via. The termination pad may be formed at an end of the via stub opposite at least one of the first location and the second location.

主权项

1. A circuit board, comprising:
a first trace formed in a first layer of the circuit board; a second trace formed in a second layer of the circuit board; a via configured to electrically couple the first trace to the second trace, the via comprising a via stub corresponding to a first portion of a length of the via not within a second portion of the via between a first location in which the first trace is electrically coupled to the via and a second location in which the second trace is electrically coupled to the via; a first termination pad formed at an end of the via stub opposite at least one of the first location and the second location; and one or more second termination pads formed at one or more layers of the circuit board other than the first layer and the second layer, wherein the one or more second termination pads are smaller in size than the first termination pad.
