Hamwe no kuzamura ibicuruzwa byabakiriya, bigenda bitera imbere bigana ku cyerekezo cyubwenge, bityo rero ibisabwa kugirango PCB ibangikanye bigenda birushaho gukomera, ibyo bikaba binateza imbere gukura kwikoranabuhanga rya tekinoroji.
Ni ubuhe buryo bwo kubangamira?
1. Kurwanya biterwa no guhinduranya amashanyarazi mubigize bifitanye isano na capacitance na inductance.Iyo hari ibimenyetso bya elegitoronike byoherejwe mu kiyobora, kurwanya yakira byitwa impedance.
2. Kurwanya ni ukurwanya guterwa numuyoboro utaziguye kubice, bifitanye isano na voltage, résistance, na current.
Gushyira mu bikorwa inzitizi ziranga
1. Bikoreshwa muburyo bwihuse bwo kohereza no kwihuta kwinshi, imikorere yamashanyarazi itangwa ninama yacapwe igomba kuba ishobora kwirinda kugaragarira mugihe cyo kohereza ibimenyetso, kugumana ibimenyetso, kugabanya igihombo, no kugira uruhare ruhuye.Byuzuye, byizewe, byukuri, nta mpungenge, kandi nta rusaku rwerekana ibimenyetso.
2. Ingano ya impedance ntishobora kumvikana gusa nkinini nini nziza cyangwa ntoya, urufunguzo ruhuye.
Kugenzura ibipimo biranga inzitizi
Dielectric ihoraho yurupapuro, ubunini bwurwego rwa dielectric, ubugari bwumurongo, uburebure bwumuringa, nubunini bwa mask yagurishijwe.
Ingaruka no kugenzura mask yabagurisha
1. Ubunini bwa mask yagurishijwe bugira ingaruka nke kuri impedance.Umubyimba wa mask yo kugurisha wiyongeraho 10um, kandi agaciro ka impedance gahinduka 1-2 oms gusa.
2. Mu gishushanyo, hari itandukaniro rinini hagati yo guhitamo igifuniko kandi nta mask yo kugurisha igifuniko, impera imwe ya 2-3 oms, hamwe na 8-10 itandukanye.
3. Mugukora imbaho za impedance, ubunini bwa mask yagurishijwe mubisanzwe bigenzurwa ukurikije ibisabwa.
Ikizamini cya Impedance
Uburyo bwibanze nuburyo bwa TDR (Time Domain Reflectometry).Ihame shingiro ni uko igikoresho gisohora ibimenyetso bya pulse, bigasubizwa inyuma binyuze mu kizamini cyikibaho cyumuzingi kugirango bapime impinduka mubiranga inzitizi ziterwa n’ibyuka bihumeka.Nyuma ya mudasobwa isesengura ibiranga impedance, ibisohoka biranga impedance irasohoka.
Gukemura ibibazo
1. Kubireba ibipimo byo kugenzura inzitizi, ibisabwa kugenzura birashobora kugerwaho hifashishijwe guhinduranya mubikorwa.
2. Nyuma yo kumurika mubikorwa, ikibaho gikataguwe kandi kigasesengurwa.Niba ubunini bwikigereranyo bwagabanutse, ubugari bwumurongo burashobora kugabanuka kugirango byuzuze ibisabwa;niba umubyimba ari mwinshi, umuringa urashobora kubyimba kugirango ugabanye agaciro ka impedance.
3. Mu kizamini, niba hari itandukaniro ryinshi hagati yimyumvire nukuri, ikintu kinini gishoboka nuko habaho ikibazo cyubwubatsi hamwe nigishushanyo mbonera.
