He aha te microvia?
E ai ki te whakamāramatanga hou i roto i te IPC-T-50M, ko te microvia he hanganga matapo me te ōwehenga āhua mōrahi o te 1:1, e mutu ana i runga i te whenua ūnga me te hohonutanga katoa kāore e neke atu i te 0.25mm i inehia mai i te pepa whenua hopu o te hanganga ki te whenua ūnga.
E tautuhia ana hoki e te IPC-6012 te hanganga o tētahi Microvia.
He hanganga matapo te Microvia me te ōwehenga āhua mōrahi o te 1:1 i waenga i te whānui me te hōhonutanga o te kōhao, me te hōhonutanga katoa kāore e neke atu i te 0.25 mm, ina inehia mai i te mata ki te papa ūnga, ki te papa rānei.
Ko te tikanga, e whakaarohia ana e te NCAB ko te matotoru o te dielectric i waenga i te mata me te papa tohutoro he 60 – 80um.
Ko te whānuitanga o te diameter o ngā microvia he 80-100 microns. Ko te ōwehenga noa kei waenga i te 0.6: 1 ki te 1: 1, ko te mea pai ko te 0.8: 1.
