Ukuhlolwa komgangatho/uVavanyo
Uvavanyo lwe-PCB luqhuba iimvavanyo ezahlukeneyo kwiibhodi zeesekethe eziprintiweyo zokuqinisekisa umgangatho kunye nokusebenza kwazo, ukuqinisekisa ukupheliswa okuchanekileyo kwazo naziphi na iziphene okanye imiba enokuthi yenzeke ngexesha lenkqubo yokuvelisa, ukugqiba ukuba banokuhlangabezana neenkcukacha kunye nokusebenza, ngelixa bephucula ukusebenza kakuhle kunye nokunciphisa iindleko.Iindleko zokugqibela.
Singabonelela ngeenkonzo ezahlukeneyo zovavanyo lwePCB, kubandakanya:
Uhlolo Lwezandla/olubonwayo:Siye saba nabahloli be-PCB ababandakanya uhlolo olubonakalayo lwezandla kwiimvavanyo ezininzi ukuqinisekisa uhlolo olucokisekileyo lwee-PCBs kunye namalungu azo, ukuqinisekisa umgangatho wemveliso.
Uvavanyo lwesilayi esincinci:Uviwo lwesilayi se-PCB lubandakanya ukusika ibhodi yesekethe ibe ngamacandelo amancinci ukuze iqwalaselwe kwaye ihlalutywe, ukuze kuchongwe iingxaki ezinokuthi zibe khona kunye neziphene.
Ukuhlolwa kwe-slice ngokuqhelekileyo kuqhutyelwa kwinqanaba lokuqala lokwenziwa kwebhodi yeesekethe ukuze kuqinisekiswe ukufumanisa ngexesha kunye nokulungiswa kwemiba ngexesha loyilo kunye nenkqubo yokuvelisa.Le ndlela inokukhangela i-welding, i-interlayer uxhumano, ukuchaneka kombane, kunye neminye imiba.Xa kuqhutywa uvavanyo lwe-biopsy, i-microscope okanye i-electron microscope yokuskena idla ngokusetyenziswa ukujonga kunye nokuhlalutya izilayi.
Uvavanyo lombane lwe-PCB:Uvavanyo lombane lwe-PCB lunokunceda ukuqinisekisa ukuba iiparamitha zombane kunye nokusebenza kwebhodi yesekethe ziyahlangabezana nokulindelweyo, kwaye inokuchonga iziphene kunye neengxaki.
Uvavanyo lombane lwe-PCB luhlala lubandakanya uvavanyo lokuqhagamshelwa, uvavanyo lokuxhathisa, ukuvavanywa komthamo, uvavanyo lwe-impedance, uvavanyo lwemfezeko yomqondiso, kunye novavanyo lokusetyenziswa kwamandla.
Uvavanyo lombane lwe-PCB lunokusebenzisa izixhobo zokuvavanya ezahlukeneyo kunye neendlela, ezifana nezixhobo zokuvavanya, ii-multimeters zedijithali, i-oscilloscopes, i-spectrum analyzers, njl.
Uvavanyo lwe-AOI:Uvavanyo lwe-AOI (uHlolo oluzenzekelayo lwe-Optical) yindlela yokufumanisa ngokuzenzekelayo iibhodi zeesekethe eziprintiweyo ngeendlela zokukhanya.Ingasetyenziselwa ukufumanisa ngokukhawuleza iziphene kunye neengxaki kwinkqubo yokuvelisa iibhodi zeesekethe eziprintiweyo, ukuphepha iimpazamo kwimveliso yemveliso, kunye nokuphucula umgangatho weebhodi zeesekethe eziprintiweyo.Umgangatho othembekileyo, ukunciphisa amazinga okusilela, kunye nokuphucula ukusebenza kakuhle kwemveliso kunye nemveliso yemveliso.
Kuvavanyo lwe-AOI, izixhobo ezithile zokubona ezifana neekhamera ezinesisombululo esiphezulu, imithombo yokukhanya, kunye nesoftware yokulungisa umfanekiso zisetyenziselwa ukuskena kunye nokuthatha imifanekiso yePCB eyenziweyo, kwaye ke imifanekiso ethathiweyo ithelekiswa netemplate esetwe kwangaphambili.Ewe, ukufumanisa ngokuzenzekelayo iziphene kunye nemiba enokwenzeka, kubandakanywa i-solder joints, amacandelo, iisekethe ezimfutshane kunye neesekethe ezivulekileyo, ukuchaneka, iziphene zomhlaba, njl.
I-ICT:Kuvavanyo lweSekethe kusetyenziselwa ukuvavanya amacandelo e-elektroniki kunye nokusebenza koqhagamshelo lwesekethe kwibhodi yesekethe.Uvavanyo lwe-ICT lunokuqhutywa kwizigaba ezahlukeneyo zemveliso ye-PCB, njengasemva kokuveliswa kwe-PCB, ngaphambi okanye emva kofakelo lwecandelo, ukuchonga ngokukhawuleza nokulungisa iingxaki kwibhodi yesekethe kunye nokuzisingatha ngexesha elifanelekileyo.
Uvavanyo lwe-ICT lusebenzisa izixhobo zovavanyo ezizodwa kunye nesoftware ukuvavanya ngokuzenzekelayo amacandelo e-elektroniki kunye neziqhagamshelo kwiiPCB.Isixhobo sokuvavanya sinxibelelana namanqaku ovavanyo kwibhodi yesekethe ngokusebenzisa iiprobe kunye neeclamps ukubona iimpawu zombane zamacandelo e-elektroniki kwibhodi yesekethe, njenge-resistors, capacitors, inductors, transistors, njl. qinisekisa ukuba uqhagamshelo lwayo lombane lusebenza ngendlela eyiliweyo.
Uvavanyo lweNaliti ebhabhayo:I-Flying Needle Test isebenzisa inkqubo ye-probe ezenzekelayo ukuvavanya uqhagamshelwano lwesekethe kunye nemisebenzi kwi-PCB.Le ndlela yokuvavanya ayifuni ukulungiswa kovavanyo olubiza kakhulu kunye nexesha lenkqubo, kodwa endaweni yoko isebenzisa iiprobes ezishukumayo ukuqhagamshelana nomphezulu we-PCB ukuvavanya uqhagamshelwano lwesekethe kunye nezinye iiparamitha.
Uvavanyo lwenaliti ebhabhayo lubuchule bovavanyo olungaqhagamshelwanga olunokuvavanya nayiphi na indawo yebhodi yesekethe, kubandakanywa neebhodi zesekethe ezincinci kunye ezixineneyo.Iingenelo zale ndlela yokuvavanya zixabiso eliphantsi lovavanyo, ixesha elifutshane lokuvavanya, ukukhululeka kotshintsho loyilo lwesekethe, kunye novavanyo olukhawulezayo lwesampulu.
Uvavanyo lwesekethe olusebenzayo:Uvavanyo lwesekethe olusebenzayo yindlela yokuqhuba uvavanyo olusebenzayo kwi-PCB ukuqinisekisa ukuba uyilo lwayo luyahlangabezana neenkcukacha kunye neemfuno.Yindlela yokuvavanya ebanzi enokuthi isetyenziswe ukujonga ukusebenza, umgangatho womqondiso, uqhagamshelwano lwesekethe, kunye neminye imisebenzi yeePCB.
Uvavanyo lwesekethe olusebenzayo ludla ngokuqhutywa emva kokuba i-wiring ye-PCB igqityiwe, kusetyenziswa izixhobo zokuvavanya kunye neenkqubo zokuvavanya ukulinganisa iimeko zokusebenza ezichanekileyo ze-PCB kunye nokuvavanya impendulo yayo phantsi kweendlela ezahlukeneyo zokusebenza.Inkqubo yokuvavanya inokuphunyezwa ngeprogram yesoftware, enokuvavanya imisebenzi eyahlukeneyo yePCB, kubandakanya igalelo / imveliso, ixesha, umbane wombane, okwangoku kunye nezinye iiparamitha.Kwangaxeshanye, eli phepha liyakwazi ukubona imiba emininzi enokubakho ngeePCB, ezinje ngeesekethe ezimfutshane, iisekethe ezivulekileyo, unxibelelwano olungachanekanga, njl. njl., kwaye inokubona ngokukhawuleza kwaye ilungise le miba ukuqinisekisa ukusebenza kunye nokuthembeka kweePCB.
Uvavanyo lwesekethe olusebenzayo yindlela yovavanyo elungiselelweyo efuna ukucwangciswa kunye noyilo lohlengahlengiso lwePCB nganye.Ke ngoko, ixabiso liphezulu kakhulu, kodwa linokubonelela ngeziphumo zovavanyo ezibanzi, ezichanekileyo nezithembekileyo.
