6 Layeri FR4 ENIG Igenzura Impedance PCB
Ibintu byerekana Impedance yagenzuwe
Inzitizi iranga PCB isanzwe igenwa nubushake bwayo nubushobozi bwayo, kurwanya no kwitwara.Izi ngingo ni imikorere yubunini bwumubiri bwumuzunguruko, dielectric ihoraho hamwe nuburinganire bwa dielectric bwibikoresho bya PCB substrate.Muri rusange, umurongo utambamirwa PCB uri hagati ya 25 na 125Ω.Imiterere ya PCB igena agaciro ka impedance igizwe nibintu bikurikira:
Ubugari nubunini bwumurongo wumuringa wo hejuru no hepfo
Ubugari bw'insinga z'umuringa hejuru no hepfo.Inzira yimbere yimbere yinteko nizunguruka ni 0.5oz 3 / 3mil kugeza 6oz 15 / 12mil umurongo wumurongo wumuringa, kandi intera yumurongo winyuma iratandukanye kuva 1 / 3oz 3 / 3mil kugeza 6oz 15 / 12mil.
Isahani yibanze cyangwa igice cyakize cyimbitse kumpande zombi z'umuringa
Urupapuro rwakize rukoreshwa nkurwego rwo guhuza gufata imbaho zose hamwe muri PCB.Mugushushanya impedance igenzura PCB, ubunini bwurupapuro rwakize igice cyuruhande rwibanze rugomba kuba rumwe.
Dielectric ihoraho ya PCB yibanze hamwe nimpapuro zikize
Niba dielectric ihoraho ya plaque yibanze hamwe nimpapuro yakize igice gitandukanye, impedance nayo izahinduka.Kubwibyo, dielectric ihoraho ya byombi igomba kuba imwe.
Kwerekana ibikoresho
Umurongo wo gushiraho byikora
Umurongo wa PTH
