He aha ka microvia?
Wahi a ka wehewehe hou i loko o ka IPC-T-50M he microvia kahi hale makapō me ka lākiō hiʻohiʻona kiʻekiʻe o 1: 1, e hoʻopau ana ma kahi ʻāina i hoʻopaʻa ʻia me ka hohonu hohonu ʻaʻole i oi aku ma mua o 0.25mm i ana ʻia mai ka pahu hopu ʻāina o ka hale a hiki i ka. ka ʻāina i kuhikuhi ʻia.
Ho'ākāka pū ka IPC-6012 i ke ʻano o kahi Microvia.
ʻO ka Microvia kahi hale makapō me ka nui o ke ʻano o ka 1: 1 ma waena o ke anawaena o ka lua a me ka hohonu, me ka hohonu o ka hohonu ʻaʻole i ʻoi aku ma mua o 0.25 mm, ke ana ʻia mai ka ʻili a i ka papa kuhikuhi a i ʻole ka mokulele.
Manaʻo maʻamau ka NCAB i ka mānoanoa dielectric ma waena o ka ʻili a me ka papa kuhikuhi he 60 - 80um.
ʻO nā anawaena o ka microvia he 80-100 microns. ʻO ka RATIO maʻamau ma waena o 0.6: 1 a i 1: 1, kūpono 0.8: 1.
