Kugirango ugere kumikorere myiza yumuzunguruko wa elegitoronike, imiterere yibigize hamwe no guhuza insinga ni ngombwa cyane.Kugirango dushushanye aPCBhamwe nubwiza bwiza nigiciro gito.Amahame rusange akurikira agomba gukurikizwa:
Imiterere
Ubwa mbere, tekereza ubunini bwa PCB.Niba ingano ya PCB ari nini cyane, imirongo yacapwe izaba ndende, impedance iziyongera, ubushobozi bwo kurwanya urusaku bizagabanuka, kandi ibiciro nabyo biziyongera;niba ari nto cyane, gusohora ubushyuhe ntibizaba byiza, kandi imirongo iherekejwe izahungabana byoroshye.Nyuma yo kumenya ingano ya PCB, menya aho ibice byihariye biri.Hanyuma, ukurikije imikorere yumuzunguruko, ibice byose byumuzingi byashyizwe hanze.
Mugihe cyo kumenya aho ibice byihariye biri, amahame akurikira agomba kubahirizwa:
Gabanya ihuriro hagati yumurongo mwinshi cyane bishoboka, kandi ugerageze kugabanya ibipimo byabo byo gukwirakwiza no guhuza amashanyarazi.Ibigize byoroshye kwivanga ntibishobora kuba hafi yundi, kandi ibyinjira nibisohoka bigomba kubikwa kure hashoboka.
May Hashobora kubaho itandukaniro ryinshi rishobora kuba hagati yibice bimwe na bimwe cyangwa insinga, kandi intera iri hagati yabyo igomba kwiyongera kugirango wirinde impanuka ngufi iterwa no gusohoka.Ibice bifite voltage ndende bigomba gutondekwa ahantu bitagerwaho byoroshye nintoki mugihe cyo gukemura.
Ibice bifite uburemere burenga 15 g bigomba gushyirwaho imitwe hanyuma bigasudwa.Ibyo bice binini, biremereye, kandi bitanga ubushyuhe bwinshi ntibigomba gushyirwa ku kibaho cyanditse, ahubwo bigomba gushyirwa ku cyapa cyo hasi cya chassis ya mashini yose, kandi hagomba gusuzumwa ikibazo cyo gukwirakwiza ubushyuhe.Ibikoresho byubushyuhe bigomba kubikwa kure yubushyuhe.
④ Kubijyanye nimiterere yibice bishobora guhindurwa nka potentiometero, ibishishwa bya inductance bishobora guhinduka, capacator zihinduka, hamwe na micrike ihindura, ibisabwa byimiterere yimashini yose bigomba kwitabwaho.Niba ihinduwe imbere muri mashini, igomba gushyirwa ku kibaho cyanditse aho byoroshye guhinduka;niba ihinduwe hanze yimashini, umwanya wacyo ugomba guhuzwa numwanya wo guhinduranya knob kumwanya wa chassis.
Ukurikije igice gikora cyumuzunguruko, mugihe ushyizeho ibice byose bigize uruziga, amahame akurikira agomba kubahirizwa:
Range Tegura umwanya wa buri gice cyumuzunguruko gikora ukurikije imigendekere yumuzunguruko, kugirango imiterere yoroherezwe kuzenguruka ibimenyetso, kandi icyerekezo cyikimenyetso kigumane uko bishoboka.
② Fata ibice byingenzi bigize buri muzunguruko ukora nkikigo hanyuma ukore imiterere yacyo.Ibigize bigomba gushushanywa, neza kandi byoroshye gushushanya kuri PCB, kugabanya no kugabanya kuyobora no guhuza ibice.
③ Kumuzunguruko ukorera kumurongo mwinshi, ibipimo byo gukwirakwiza ibice bigomba kwitabwaho.Mubisanzwe, umuzenguruko ugomba gutondekanya ibice muburyo bushoboka bwose.Muri ubu buryo, ntabwo ari bwiza gusa, ariko kandi biroroshye guteranya no gusudira, kandi byoroshye kubyara umusaruro.
ComponentsIbigize biherereye ku nkombe y’umuzunguruko muri rusange ntibiri munsi ya mm 2 uvuye ku nkombe y’umuzunguruko.Imiterere myiza kumwanya wumuzunguruko ni urukiramende.Ikigereranyo cya aspect ni 3: 2 cyangwa 4: 3.Iyo ubunini bwikibaho cyumuzunguruko burenze mm 200-150 mm, hagomba gutekerezwa imbaraga zumukanishi wibibaho.

Amahame ni aya akurikira:
Ints Intsinga zikoreshwa mugusohora no gusohora ibintu bigomba kwirinda kuba hafi no kubangikanya bishoboka.Nibyiza kongeramo umugozi wubutaka hagati yumurongo kugirango wirinde guhuza ibitekerezo.
Ubugari ntarengwa bwumurongo wacapwe wumurongo wumuzunguruko ugenwa cyane cyane nimbaraga zifatika hagati yinsinga hamwe na insimburangingo hamwe nigiciro kiriho kinyuramo.
Iyo ubunini bwumuringa wumuringa ari 0,05 mm nubugari bwa mm 1 kugeza kuri 15, ubushyuhe ntibuzaba hejuru ya 3 ° C binyuze mumashanyarazi ya 2 A, bityo ubugari bwinsinga ni mm 1.5 kugirango bujuje ibisabwa.Kumuzunguruko uhuriweho, cyane cyane imiyoboro ya sisitemu, ubugari bwinsinga ya 0.02-0.3 mm mubisanzwe byatoranijwe.Birumvikana, uko bishoboka kwose, koresha insinga nini, cyane cyane insinga nubutaka.
Umwanya muto wabatwara ugenwa cyane cyane nubushakashatsi bubi cyane hagati yimirongo na voltage yo kumeneka.Kumuzunguruko uhuriweho, cyane cyane imiyoboro ya sisitemu, mugihe cyose inzira ibyemerera, ikibuga gishobora kuba gito nka 5-8 um.
Inguni z'insinga zacapwe muri rusange zisa na arc, mugihe inguni iburyo cyangwa inguni zirimo bizagira ingaruka kumikorere y'amashanyarazi mumuzunguruko mwinshi.Byongeye kandi, gerageza wirinde gukoresha ahantu hanini h'umuringa, bitabaye ibyo, iyo ushyutswe igihe kirekire, biroroshye gutera ifu y'umuringa kwaguka no kugwa.Mugihe hagomba gukoreshwa ahantu hanini h'umuringa, nibyiza gukoresha imiterere ya gride, ifite akamaro ko gukuraho gaze ihindagurika iterwa no gufatira hagati yumuringa wumuringa na substrate iyo ushushe.
Pad
Umwobo wo hagati wa padi ni munini cyane kurenza umurambararo wigikoresho.Niba padi ari nini cyane, biroroshye gukora igurishwa ryukuri.Diameter yo hanze D ya padi mubusanzwe ntabwo iri munsi ya d + 1,2 mm, aho d ni diameter yayoboye.Kumurongo mwinshi wa digitale, diameter ntarengwa ya padi irashobora kuba d + 1.0 mm.
