An example circuit board structure includes: a substrate; and vias that are electrically conductive and that pass through the substrate to enable electrical connection through the circuit board structure. The substrate is thinner, and lengths of the vias are shorter, in first areas of the circuit board structure that deliver first speed signals than in second areas of the circuit board structure that deliver second speed signals and power. The first speed signals have a shorter rise time than the second speed signals.

An automated test equipment interface system, e.g., for attaching a handler to a test head, includes a device interface board assembly. The device interface board assembly includes a stiffener frame having a frame body that is configured for attachment to a test head, alignment brackets connected to the frame body, and cam followers connected to the alignment brackets. The system also includes a docking device. The docking device includes a docking plate that is configured for attachment to a handler, pull-down ramps connected to the docking plate and movable between a retracted position and an extended position, an actuator operable to initiate movement of the pull-down ramps, and a coupling that translates movement of the actuator to corresponding movements of the pull-down ramps. The pull-down ramps can include cam surfaces that are configured to engage the cam followers of the device interface board assembly during movement between the retracted and extended positions to pull the device interface board assembly towards the docking plate.
