I-High Frequency PCB wuhlobo lwe-PCB olusetshenziselwa ukuhanjiswa kwesiginali ezinhlobonhlobo zezicelo ezibandakanya iselula, i-microwave, imvamisa yomsakazo kanye nezicelo zokuklama ngejubane.
Ama-High Frequency board eza nama-laminate aphezulu kakhulu kunzima ukuwakha ngoba adinga ukugcina ukudluliswa kokushisa kwesicelo, ngenxa yokuzwela kwesiginali.
Izinto ezikhethekile zisetshenziselwa ukuthola imvamisa ephezulu enikezwa yi-High Frequency PCB.
Izici zebhodi lemvamisa ephezulu zingenza ukusebenza kukonke kwesiginali, ngokufanayo noma yiluphi ushintsho kunani le-Er lezinto ezisetshenzisiwe lingathinta kakhulu impedance yebhodi.
Iningi lochwepheshe lithanda okokusebenza kwe-rogers dielectric ngoba kuvela ukuthi akubizi kakhulu, kunenani eliphansi le-DK ne-DF, kunciphise ukulahleka kwesiginali futhi kubonakala kufanelekile ekusetshenzisweni kwamanga nokwenziwa kwe-prototyping.
I-Teflon kungenye into ejwayelekile esetshenziswa enqubeni yokukhiqiza ye-PCB yemvamisa ephezulu, eza nobuningi be-5GHz.Ngokwe-DK, DF nento yokumunca amanzi, iTefon iyona ehamba phambili, kepha ebiza kakhulu kune-FR4.
Uma amaphrojekthi akho adinga imvamisa engaphezu kwe-10GHz ngekhwalithi ephezulu nesiginali ezinzile, khona-ke iTefon iyona engcono kakhulu.
Izimpawu zamaza aphezulu zisengozini yomsindo futhi ziza nokubekezelelana okukhulu kwe-impedance uma kuqhathaniswa namabhodi wesifunda ajwayelekile.
