MH means Mechanical type but a hole, it have no pin or pad. so Valor NPI will ignore this pin type during pin-to-pad check.
thx again,understand what the "MH" really means now, but for the mechanical pin ,what shall i classify it? ET is for electrical through, MT is for mechanical through,but the respective PCB design is PTH. What shall i classify for mechanical plastic pin whose PCB design is NPTH,such as the RJ45's fixed pin?
As per my understanding your requirement is to add " pin type category " from the valor default settings,It needs to be added " MH " in addition to the given picture .Right?
Thanks and Regards
