Ubuhanga busanzwe bwo gukemura PCB

Kuva kuri PCB Isi.

 

Yaba ikibaho cyakozwe nundi muntu cyangwa ikibaho cya PCB cyateguwe kandi cyakozwe nawe wenyine, ikintu cya mbere cyo kukibona ni ukugenzura ubusugire bwinama, nko gutobora, gucamo, imiyoboro migufi, imiyoboro ifunguye, no gucukura.Niba ikibaho kirushijeho kuba cyiza Komera, noneho urashobora kugenzura agaciro ko guhangana hagati yumuriro ninsinga zubutaka munzira.

Mubihe bisanzwe, ikibaho cyakozwe ubwacyo kizashyiraho ibice nyuma yuko amabati arangiye, kandi niba abantu babikora, ni ikibaho cyubusa cyuzuye PCB gifite umwobo.Ugomba kwishyiriraho ibice ubwawe iyo ubibonye..

Abantu bamwe bafite amakuru menshi kubyerekeye imbaho ​​za PCB bashushanya, kuburyo bakunda kugerageza ibice byose icyarimwe.Mubyukuri, nibyiza kubikora buhoro buhoro.

 

Ikibaho cyumuzunguruko wa PCB munsi yikibazo
Ubuyobozi bushya bwa PCB burashobora gutangira kubice bitanga amashanyarazi.Inzira yizewe ni ugushira fuse hanyuma ugahuza amashanyarazi (mugihe gusa, nibyiza gukoresha amashanyarazi ahamye).

Koresha amashanyarazi ahamye kugirango ushireho amashanyarazi arenze urugero, hanyuma wongere buhoro buhoro imbaraga z'amashanyarazi ahamye.Iyi nzira ikeneye gukurikirana ibyinjira byinjira, voltage yinjira hamwe nibisohoka voltage yubuyobozi.

Iyo voltage ihinduwe hejuru, nta kurinda birenze urugero kandi ibisohoka n’umuvuduko ni ibisanzwe, noneho bivuze ko igice cyo gutanga amashanyarazi cyubuyobozi nta kibazo.Niba ibisanzwe bisohoka voltage cyangwa kurenza-kurinda birenze, noneho hagomba gukorwa iperereza kubitera amakosa.

 

Kwinjiza ibice byumuzunguruko
Buhoro buhoro shyiramo module mugihe cyo gukemura.Mugihe buri module cyangwa module nyinshi zashizweho, kurikiza intambwe yavuzwe haruguru kugirango ugerageze, ifasha kwirinda andi makosa yihishe mugitangira igishushanyo, cyangwa amakosa yo kwishyiriraho ibice, bishobora gutuma umuntu yaka cyane.Ibice bibi.

Niba kunanirwa bibaye mugihe cyo kwishyiriraho, uburyo bukurikira bukoreshwa mugukemura ibibazo:

Uburyo bwo gukemura ikibazo kimwe: uburyo bwo gupima voltage.

 

Mugihe uburinzi burenze urugero bubaye, ntukihutire gusenya ibice, banza wemeze amashanyarazi pin pin ya buri chip kugirango urebe niba ari murwego rusanzwe.Noneho reba voltage yerekana, voltage ikora, nibindi hanyuma.

Kurugero, mugihe tristoriste ya silicon ifunguye, voltage yumurongo wa BE izaba hafi 0.7V, naho ihuriro rya CE rizaba 0.3V cyangwa munsi yayo.

Iyo ugerageza, usanga voltage ya BE ihuza hejuru ya 0.7V (tristoriste idasanzwe nka Darlington itarimo), noneho birashoboka ko ihuriro rya BE rifunguye.Mukurikirane, reba voltage kuri buri ngingo kugirango ukureho amakosa.

 

Uburyo bwo gukemura ibibazo bibiri: uburyo bwo gutera ibimenyetso

 

Uburyo bwo gutera ibimenyetso biragoye kuruta gupima voltage.Iyo ibimenyetso byinkomoko byoherejwe kumurongo winjiza, dukeneye gupima imiterere ya buri ngingo kugirango tumenye amakosa yibyerekezo.

Birumvikana, urashobora kandi gukoresha twezeri kugirango umenye ibyinjira.Uburyo nugukoraho ibyinjira byinjira hamwe na twezeri, hanyuma ukareba igisubizo cyinjira.Mubisanzwe, ubu buryo bukoreshwa mugihe cyamajwi na videwo byongera amajwi (icyitonderwa: umuzenguruko ushyushye hamwe n’umuzunguruko mwinshi) Ntukoreshe ubu buryo, bukunze guhura nimpanuka zamashanyarazi).

Ubu buryo bugaragaza ko icyiciro kibanza gisanzwe kandi icyiciro gikurikira kirasubiza, amakosa rero ntabwo ari murwego rukurikira, ahubwo ni kurwego rwabanje.

Uburyo bwo gukemura ibibazo bitatu: ubundi

 

Ibintu bibiri byavuzwe haruguru biroroshye kandi byoroshye.Mubyongeyeho, kurugero, kubona, kunuka, kumva, gukorakora, nibindi bikunze kuvugwa, ni injeniyeri bakeneye uburambe kugirango babashe kumenya ibibazo.

Mubisanzwe, "reba" ntabwo ari ukureba uko ibikoresho bipima byifashe, ahubwo ni ukureba niba isura yibigize byuzuye;"Impumuro" bivuga cyane cyane niba impumuro yibigize idasanzwe, nkumunuko wo gutwika, electrolyte, nibindi. Ibigize rusange birimo Iyo byangiritse, bizatanga impumuro yaka idashimishije.

 

Kandi "gutega amatwi" ahanini ni ukumva niba ijwi ryinama risanzwe mubihe byakazi;kubyerekeye "gukoraho", ntabwo ari ugukoraho niba ibice birekuye, ahubwo ni ukumva niba ubushyuhe bwibigize ari ibisanzwe mukuboko, kurugero, bigomba kuba bikonje mugihe cyakazi.Ibigize birashyushye, ariko ibice bishyushye birakonje bidasanzwe.Ntugakubite amaboko yawe mugihe cyo gukoraho kugirango wirinde ko ukuboko gutwikwa n'ubushyuhe bwinshi.
