Inqaku lovavanyo kwi-PCB yipali yobhedu evelisiweyo enokusetyenziselwa ukukhangela ukuba i-COMICE isebenza na. Ngexesha lemveliso, abasebenzisi banokufaka imiqondiso yovavanyo ngokusebenzisa amanqaku ovavanyo ukuze babone imiba enokubakho. Iziphumo zovavanyo ezichaza ukuba isibonakaliso esinikiweyo siphantsi / siphezulu xa sithelekiswa nesiphumo esinqwenelekayo kunye notshintsho olufanelekileyo lunokwenziwa ukufezekisa okufanayo.

IInqaku lovavanyo lwePCBkufuneka ibekwe kumaleko angaphandle weBhodi. Oku kuvumela izixhobo zovavanyo zikufuphi ukuze zinxibelelane nayo kwaye zenze uvavanyo. Iingcebiso zovavanyo zovavanyo ziyafumaneka kwiintlobo ezahlukeneyo zokuvavanywa Oku kuvumela abaqulunqi ukuba banyule izikhonkwane ze-thru-hole ekhoyo kunye ne-vias ezibhodini njengendawo yokuvavanya.

Iindidi zamanqaku ovavanyo

Inqaku lovavanyo lweProbe

Uhlobo lokuqala lwendawo yovavanyo yeyona ndawo ifikeleleka ngokulula yingcali usebenzisa isixhobo esiphethwe ngesandla okanye i-probe. La manqaku ovavanyo anokuchongwa ngokulula njenge "Gnd", "PWR" njl.njl.

Amanqaku ovavanyo ezenzekelayo

Uhlobo lwesibini lwendawo yovavanyo lisetyenziselwa izixhobo zovavanyo ezizenzekelayo. Amanqaku ovavanyo ozenzekelayo kwi-PCB anguVia, umngxunya wemingxunya we-thru, kunye neepads ezincinci zokufika kwentsimbi eyilelwe ukulungiselela iinkqubo zeenkqubo zovavanyo ezizenzekelayo. Amanqaku ovavanyo ozenzekelayo avumela iinkqubo zovavanyo ezizenzekelayo ezisebenzisa iindlela zovavanyo ezizenzekelayo. Zintathu iindidi:

1. Uvavanyo lwebhodi yeBhodiUkuvavanywa kwebhodi yeBhodi kwenziwa ngaphambi kwendibano yamacandelo ukuqinisekisa ukuba kukho ukunxibelelana kombane okufanelekileyo kuyo yonke iBhodi.

2. Ukuvavanywa kwesekethe (ICT):Uvavanyo lwe-ICT lwenziwa ukuqinisekisa ukuba onke amacandelo akhoyo kwiBhodi ayasebenza njengoko kufanele. I-fition kwi-fixting yovavanyo iya kudibana namanqaku ovavanyo kwiibhodi zesekethe ukwenza uvavanyo.

I-3. Ukubhalwa kweProbeng Probe (FTT):Uvavanyo lweProbeng Probe (FTT) luvavanyo oluzenzekelayo olusetyenziselwa ukuvavanya ukusebenza ngokuchanekileyo kwezinto kwiBhodi yePCB. Kolu vavanyo, iindlela ezimbini okanye ezingaphezulu zilungiselelwe ukuhambisa iBhodi emoyeni kwaye zifikelele icandelo elithile lezikhonkwane umntu ngamnye ukuba afumane iimpazamo, iinqobo zokuziphatha, kunye nokuqhelaniswa nenqanaba, kunye nokuqhelaniswa nenqanaba.

Izinto ekufuneka ziqwalaselwe ngelixa uphumeza inqaku lovavanyo kwi-PCB:

● Ukuhanjiswa kwenqaku lovavanyo: Iindawo zovavanyo kufuneka zisasazwe ngokuhlwa nje kwi-PCB ukuze iimvavanyo ezininzi zinokwenziwa ngaxeshanye.
● Icala lebhodi: Amanqaku ovavanyo kufuneka abekwe kwicala elinye le-PCB enceda ukugcina ixesha kunye nemali.
● Umgama omncinci wokuvavanya: Amanqaku ovavanyo kufuneka abe nomgama omncinci we-0.100 phakathi kwabo ukuphucula ukusebenza kakuhle kovavanyo,

IINGXAKI ZOKUXABISA IINGXAKI ZOKUVAVANYA KWI-PCB:

● Ukuchongwa kwempazamo ngokulula
● Ixesha kunye nokugcina iindleko
● Kulula ukuyisebenzisa

Amanqaku ovavanyo kubalulekile ekuqinisekiseni ukuthembeka kwe-PCB. Inani lamanqaku ovavanyo kwiBhodi ye-PCB kufuneka inqunyelwe njengoko iyindawo yobhedu evelisiweyo ngengozi kwenye inqaku lovavanyo kunye nomonakalo wesekethe.
