Iyo bigeze kuri impedance, abajenjeri benshi bafite ibibazo byinshi hamwe nayo.Kuberako haribintu byinshi bihindura bigira ingaruka kumyitwarire igenzurwa mukibaho cyacapwe, icyakora, impedance niki twakagombye gusuzuma mugihe impedance yagenzuwe?
Igisobanuro cya Impedance?
Impedance nigiteranyo cyo kurwanya no kwitwara k'umuriro w'amashanyarazi upimirwa muri Ohms.Impedance nisimburanya ryibintu biranga ibimenyetso byerekana ibimenyetso nibintu byingenzi.Umwanya muremure cyangwa urwego rwinshi, niko biba ngombwa kugenzura inzitizi.Inshuro yikimenyetso nikintu cyingenzi kubimenyetso bihuza ibice bisaba MHz ebyiri cyangwa magana atatu cyangwa zirenga.
Iboneza byinshi bitandukanye byakoreshwa mubibaho byacapwe kugirango bigerweho.Turashobora kugenzura inzitizi dukoresheje intera nubunini bwikibaho cyumuzingi.
Urwego rwo kugenzura urwego rurahari
Mubisanzwe, hari ibyiciro bitatu byo kugenzura impedance iboneka kubibaho byacapwe.
1. Kugenzura Impedance
Kugenzura Impedance bikoreshwa cyane mubishushanyo byohejuru hamwe no kwihanganira gukomeye cyangwa ibidasanzwe.Hariho ubwoko butandukanye bwo kugenzura inzitizi.Muri ibyo biranga impedance ikoreshwa.Ubundi bwoko burimo impagarike, impedance, hamwe ninjiza.
2. Kureba Impedance
Kureba Impedance bisobanura guhuza muri impedance.Inzira yo kugenzura inzitizi izagenwa nubugari bwurwego nuburebure bwa dielectric, ishobora guhinduka nkuko bikenewe.
3. Nta kugenzura Impedance
Kuberako kwihanganira inzitizi mubishushanyo bidakomeye, impedance ikwiye irashobora kugerwaho muguhuza nibisanzwe bitagenzuwe.impedance nyayo irashobora gutangwa nuwakoze PCB nta ntambwe yinyongera, Rero, nurwego ruhenze cyane.
Akamaro ko Kwirinda kugenzura inzitizi
Akamaro ko kwizerwa ni ingenzi cyane kubibaho bigenzurwa kugirango bikore neza.kuberako abashushanya PCB bagomba kwerekana inzitizi no kwihanganira bisabwa.
Ibibazo byinshi bijyanye no kugenzura impedance, urashobora kugisha inama itsinda rya injeniyeri muri PHILIFAST, bazaguha igisubizo cyiza kubibaho bya PCB.
