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