A printed circuit board includes a plurality of layer structures disposed in a stacked manner, and the printed circuit board has a disposing face. A differential pair unit and a shielding structure for shielding the differential pair unit are disposed on the disposing face. The differential pair unit includes two signal via holes, each signal via hole passes through the plurality of layer structures, and an anti-pad corresponding to each signal via hole is disposed on a ground layer through which the signal via hole passes. A part of metal of a ground layer is spaced between two anti-pads. Each signal corresponds to one anti-pad, and a ground layer is spaced between anti-pads.

Printed circuit board, backplane architecture system, and communication device

A system for testing multiple devices includes a connector holder having a plurality of holes, wherein each hole included in the plurality of holes is configured to hold a respective cable connector that connects to a cable; a device holder that is configured to hold a first device in a testing position; and an engagement mechanism that supports the connector holder and is operable to move the connector holder to an engaged position, wherein when the first device is being held by the device holder in the testing position, and a first hole included in the plurality of holes holds a first cable connector, a contact point associated with the first cable connector contacts a signal pad associated with the first device.
