Yintoni i-microvia?
Ngokwengcaciso entsha ngaphakathi kwe-IPC-T-50M i-microvia sisakhiwo esingaboniyo esinomlinganiselo ophezulu we-1: 1, ukuphelisa kumhlaba ekujoliswe kuwo ngobunzulu bubonke obungekho ngaphezu kwe-0.25mm elinganiswa ukusuka kwifoyile yomhlaba yokubamba isakhiwo ukuya umhlaba ekujoliswe kuwo.
IPC-6012 ikwachaza ubume beMicrovia.
I-Microvia yisakhiwo esiyimfama esinomlinganiselo ophezulu we-1: 1 phakathi komngxuma ububanzi kunye nobunzulu, kunye nobunzulu obupheleleyo obungekho ngaphezu kwe-0.25 mm, xa ilinganiswa ukusuka kumphezulu ukuya kwi-pad ekujoliswe kuyo okanye indiza.
Ngokuqhelekileyo i-NCAB ithatha ubukhulu be-dielectric phakathi komphezulu kunye ne-reference pad ibe yi-60 - 80um.
Imilinganiselo yobubanzi be-microvia inoluhlu lwe-80-100 microns. I-RATIO eqhelekileyo iphakathi kwe-0.6: 1 ukuya ku-1: 1, efanelekileyo 0.8: 1
