I-6 Layer FR4 ENIG Impedance Control PCB
Kungani i-PCB Izokwenza Impedance?
I-PCB impedance ibhekisela ekuphikiseni kanye nemingcele yokusabela, okusebenza njengesithiyo kumanje oshintshanayo.Ukucubungula kwe-impedance kubalulekile ku-PCB.Nasi isizathu:
I-1, i-PCB yokucabangela ukufakwa kwepulaki yezingxenye ze-elekthronikhi, ipulaki yesichibi se-SMT nayo idinga ukucabangela ukusebenza nokusebenza kokudluliselwa kwesignali, ngakho-ke kuzodinga ukwehla kwe-impedance, okungcono.
I-2, i-PCB enqubweni yokukhiqiza ngokusebenzisa i-copper deposition, i-electroplating tin (noma i-electroless plating, i-hot spray tin), i-soldering yesixhumi nezinye izinqubo, izinto ezisetshenziswayo kufanele zibe ukumelana okuphansi, ukuze kuqinisekiswe ukuthi inani eliphelele le-impedance yebhodi lesifunda ukuhlangabezana izidingo zekhwalithi yomkhiqizo, ukuze usebenze okuvamile.
3, PCB tin Plating iyona ethambekele kakhulu ezinkingeni lonke ukukhiqizwa PCB, isixhumanisi ukhiye ezithinta impedance;Isici sawo esikhulu i-oxidation elula noma i-deliquesce, ukubhula okungekuhle, ukuze i-PCB kube nzima ukuyishisela, i-impedance iphezulu kakhulu, okuholela ekusebenzeni kabi kwe-conductive noma konke ukusebenza kwe-PCB akuzinzile.
I-4, umqhubi we-PCB uzoba nokudluliswa kwesignali okuhlukahlukene, umugqa ngokwawo ngenxa yokugubha, ukushuba kwe-lamination, ububanzi bezintambo nezinye izici, kuzodala izinguquko zenani le-impedance, zenze isignali ukuhlanekezela, okuholela ekusebenzeni kwesekethe. ukwehla kwebhodi, ngakho-ke kuyadingeka ukulawula inani le-impedance ngaphakathi kwebanga elithile.
