REFERENCE METAL LAYER FOR SETTING THE IMPEDANCE OF METAL CONTACTS OF A CONNECTOR

Abstract:

A circuit board has an electrical circuit and a connector that is attached to the circuit board. The connector has metal contacts. A housing of the connector has an embedded reference metal layer that is disposed under a single-ended metal contact or differential metal contacts. The reference metal layer sets the impedance of the single-ended metal contact or the differential metal contacts.
