Yintoni i-microvia?
Ngokwenkcazo entsha ngaphakathi kwe-IPC-T-50M, i-microvia sisakhiwo esingaboniyo esinomlinganiselo ophezulu we-1:1, esiphela kumhlaba ekujoliswe kuwo onobunzulu obupheleleyo obungekho ngaphezulu kwe-0.25mm obulinganiswa ukusuka kwi-catch land foil yesakhiwo ukuya kumhlaba ekujoliswe kuwo.
I-IPC-6012 ikwachaza ulwakhiwo lweMicrovia.
IMicrovia sisakhiwo esingaboniyo esinomlinganiselo ophezulu we-aspect ratio ye-1:1 phakathi kobubanzi bomngxuma kunye nobunzulu, kunye nobunzulu obupheleleyo obungadluli kwi-0.25 mm, xa kulinganiswa ukusuka kumphezulu ukuya kwi-target pad okanye kwi-plane.
Ngokwesiqhelo i-NCAB ibona ubukhulu be-dielectric phakathi komphezulu kunye ne-reference pad njenge-60 - 80um.
Ubukhulu be-microvia bunobubanzi obuyi-80-100 microns. Umlinganiselo oqhelekileyo uphakathi kwe-0.6: 1 ukuya kwi-1: 1, ofanelekileyo yi-0.8: 1
