Nubuhe buhanga mugihe ushushanya pcb ikibaho?

1. Amategeko agenga ibice
1).Mubihe bisanzwe, ibice byose bigomba gutondekwa hejuru yubuso bwacapwe.Gusa iyo ibice byo hejuru biri hejuru cyane, birashobora kuba ibikoresho bimwe bifite uburebure buke nubushyuhe buke buke, nka chip résistoriste, chip Capacitor, IC yometse kuri IC, nibindi bishyirwa kumurongo wo hasi.
2).Hashingiwe ku kwemeza imikorere y'amashanyarazi, ibice bigomba gushyirwa kuri gride hanyuma bigashyirwa hamwe bisa cyangwa bihagaritse kugirango bibe byiza kandi byiza.Mubisanzwe, ibice ntibyemewe guhuzagurika;ibice bigomba gutondekwa neza, kandi ibyinjira nibisohoka bigomba kubikwa kure hashoboka.
3).Hashobora kubaho itandukaniro ryinshi rishobora kuba hagati yibice bimwe na bimwe cyangwa insinga, kandi intera iri hagati yabyo igomba kwiyongera kugirango wirinde imiyoboro migufi itunguranye kubera gusohoka no gusenyuka.
4).Ibice bifite voltage ndende bigomba gutondekwa ahantu bitagerwaho byoroshye nintoki mugihe cyo gukemura.
5).Ibigize biherereye kumpera yikibaho, byibura uburebure bwikibaho 2 kure yuruhande rwibibaho
6).Ibigize bigomba gukwirakwizwa neza kandi bigakwirakwizwa cyane ku kibaho cyose.
2. Ukurikije icyerekezo cyerekana ibimenyetso
1).Mubisanzwe utegure umwanya wa buri gice cyumuzunguruko gikora kimwekimwe ukurikije imigendekere yikimenyetso, ushingiye kumurongo wibanze wa buri muzunguruko ukora, hamwe nimiterere yacyo.
2).Imiterere yibigize igomba kuba yorohereza kuzenguruka ibimenyetso, kugirango ibimenyetso bishobore kubikwa mu cyerekezo kimwe gishoboka.Mubihe byinshi, icyerekezo cyerekezo cyikimenyetso gitunganijwe uhereye ibumoso ugana iburyo cyangwa kuva hejuru kugeza hasi, kandi ibice bihujwe neza ninjiza nibisohoka bigomba gushyirwa hafi yinjiza nibisohoka bihuza cyangwa bihuza.

3. Irinde kwivanga kwa electronique 1).Kubigize ibice bifite imirasire ikomeye ya electromagnetique hamwe nibice byunvikana kwinjiza amashanyarazi, intera iri hagati yabyo igomba kwiyongera cyangwa gukingirwa, kandi icyerekezo cyo gushyira ibice bigomba kuba bihuye ninsinga zacapwe zegeranye.
2).Gerageza kwirinda kuvanga ibikoresho birebire kandi bito bya voltage, hamwe nibikoresho bifite ibimenyetso bikomeye kandi bidakomeye bihujwe hamwe.
3).Kubigize ibice bitanga imbaraga za magneti, nka transformateur, disikuru, inductors, nibindi, hakwiye kwitabwaho kugabanya guca insinga zacapwe numurongo wingufu za magneti mugihe cyagenwe.Icyerekezo cya magnetiki icyerekezo cyibice byegeranye bigomba kuba perpendicular kuri mugenzi wawe kugirango bigabanye guhuza hagati yabyo.
4).Shira inkomoko yivanga, kandi igipfukisho gikingira kigomba kuba gihagaze neza.
5).Kumuzunguruko ukorera kumurongo mwinshi, hagomba gusuzumwa ingaruka zo gukwirakwiza ibice.
4. Kurwanya ubushyuhe bwumuriro
1).Kubice byo gushyushya, bigomba gutondekwa mumwanya ufasha gusohora ubushyuhe.Nibiba ngombwa, radiator cyangwa umufana muto urashobora gushyirwaho ukundi kugirango ugabanye ubushyuhe no kugabanya ingaruka kubice byegeranye.
2).Ibice bimwe byahujwe hamwe nimbaraga nini zikoreshwa, imiyoboro minini cyangwa iringaniye, résistoriste nibindi bikoresho bigomba gutondekwa ahantu hagabanijwe ubushyuhe bworoshye, kandi bigomba gutandukanywa nibindi bice intera runaka.
3).Ikintu cyumva ubushyuhe kigomba kuba hafi yikintu kigeragezwa kandi kikaguma kure yubushyuhe bwo hejuru, kugirango bitagira ingaruka kubindi bintu bitanga ubushyuhe bingana kandi bigatera imikorere mibi.
4).Iyo ushyize ibice kumpande zombi, mubisanzwe ntakintu gishyushya gishyirwa kumurongo wo hasi.

5. Imiterere y'ibice bishobora guhinduka
Kugirango imiterere yibice bishobora guhinduka nka potentiometero, ubushobozi bwa capacator zihinduka, ibishishwa bya inductance bishobora guhinduka cyangwa micro ya switch, ibisabwa byimiterere yimashini yose bigomba kwitabwaho.Niba ihinduwe hanze yimashini, umwanya wacyo ugomba guhuzwa nu mwanya wo guhinduranya knob kumwanya wa chassis;Niba ihinduwe imbere muri mashini, igomba gushyirwa kumurongo wacapwe wacapwe aho ihinduwe.Igishushanyo mbonera cyumuzingo cyacapwe SMT ikibaho cyumuzunguruko nikimwe mubice byingirakamaro mugushushanya hejuru.Ikibaho cyumuzunguruko wa SMT ninkunga yibice byumuzunguruko nibikoresho mubikoresho bya elegitoronike, bimenya guhuza amashanyarazi hagati yibice byumuzunguruko nibikoresho.Hamwe niterambere ryikoranabuhanga rya elegitoronike, ingano yimbaho ​​za pcb iragenda iba nto, kandi ubucucike buragenda bwiyongera, kandi ibice byimbaho ​​za pcb bihora byiyongera.Hejuru kandi hejuru.
