What is the maximum span that two NeXLev connectors can be placed at, on two mating boards, and not have mating alignment issues?
This is dependent on PCB fabrication tolerances for the specific PCB being designed. The PCB location tolerances from nominal would need to meet the following: The connectors can be misaligned ± 0.2 mm in the width direction, or ± 0.1mm in the length direction, and still maintain electrical continuity.
