Iyini i-microvia?
Ngokusho kwencazelo entsha ngaphakathi kwe-IPC-T-50M, i-microvia iyisakhiwo esiyimpumputhe esinesilinganiso esiphezulu se-aspect ratio esingu-1:1, esiphela endaweni eqondiwe enobubanzi obuphelele obungadluli ku-0.25mm obulinganiswa kusukela ku-catch land foil yesakhiwo kuya endaweni eqondiwe.
I-IPC-6012 ichaza futhi isakhiwo se-Microvia.
I-Microvia iyisakhiwo esiyimpumputhe esinesilinganiso esiphezulu se-aspect ratio esingu-1:1 phakathi kobubanzi bembobo nokujula, kanye nokujula okuphelele okungengaphezu kuka-0.25 mm, uma kulinganiswa kusukela ebusweni kuya endaweni eqondiwe noma endaweni ebekwe kuyo.
Ngokuvamile i-NCAB ibheka ubukhulu be-dielectric phakathi kobuso kanye nephedi yokubhekisela njengo-60 - 80um.
Ubukhulu bobubanzi be-microvia bunobubanzi obungama-micron angu-80-100. I-RATIO evamile iphakathi kuka-0.6: 1 kuya ku-1: 1, i-0.8: 1 ekahle
