Indibano yePCB yinkqubo yokuvelisa iibhodi zesekethe eziprintiweyo, ubuchule bokuvelisa obuguqula izinto ezikrwada zibe ziibhodi zePCB zeemveliso zombane.Ingasetyenziswa kumashishini amaninzi, kubandakanywa umkhosi kunye ne-aerospace.Namhlanje siza kufunda malunga nolwazi olunxulumene nePCB kunye.
I-PCB yintwana ecekethekileyo, ethe tyaba yemathiriyeli yedielectric eneendlela zokuqhuba ezifakwe kuyo.Ezi ndlela zidibanisa izinto ezahlukeneyo ze-elektroniki.Zikwasetyenziselwa ukudibanisa amacandelo kwiisokethi kwiibhodi zeesekethe eziprintiweyo.Indibano yePCB yinkqubo yokwenziwa kweebhodi zeesekethe zeemveliso zombane.Inkqubo ibandakanya iipateni zokulinganisa kwi-dielectric substrate kwaye emva koko yongeza i-electronics kwi-substrate.
Inyathelo lokuqala kwinkqubo epheleleyo yendibano yePCB kukwenza uyilo lwePCB.Uyilo lwenziwe kusetyenziswa isoftware yeCAD (Computer Aided Design).Emva kokuba uyilo lugqityiwe, luthunyelwa kwinkqubo yeCAM.Inkqubo yeCAM isebenzisa uyilo ukuvelisa iindlela zomatshini kunye nemiyalelo efunekayo ukwenza iPCB.Isinyathelo esilandelayo kukubeka iphethini efunekayo kwi-substrate, edla ngokusetyenziswa inkqubo ye-photochemical.Emva kokumisa iphethini, amacandelo e-elektroniki abekwe kwi-substrate kwaye athengiswa.Emva kokuba inkqubo yokuthengisa igqityiwe, iPCB iyacocwa kwaye ihlolwe umgangatho.Nje ukuba iphumelele ukuhlolwa, ilungele ukusetyenziswa.
Xa kuthelekiswa neendlela zendibano zePCB zemveli, ukusetyenzwa kwendibano yeSMT yanamhlanje kuneenzuzo ezininzi.Enye yeenzuzo ezinkulu kukuba indibano ye-SMT ivumela uyilo olunzima ngakumbi kunezinye iindlela.Oku kungenxa yokuba indibano ye-SMT ayifuni imingxuma yokugrumba ukuze idibanise izinto ezahlukeneyo.Oku kuthetha ukuba uyilo oluntsonkothileyo lunokwenziwa ngaphandle kokukhathazeka malunga nemida yokomba ngokomzimba.Enye inzuzo yendibano ye-SMT kukuba ikhawuleza kakhulu kunezinye iindlela.Onke amanyathelo ayimfuneko enziwa kumatshini omnye.Oku kuthetha ukuba akukho mfuneko yokuhambisa iPCB ukusuka kumatshini omnye ukuya komnye, nto leyo egcina ixesha elininzi.
Indibano ye-SMT ikwayindlela engabizi kakhulu yokuvelisa ii-PCB zeemveliso zombane.Oku kungenxa yokuba ikhawuleza kakhulu kunezinye iindlela, nto leyo ethetha ukuba kufuneka ixesha kunye nemali encinane ukuvelisa inani elifanayo leendibano zePCB.Kodwa inezinye izinto ezingeloncedo.Enye yezinto ezingeloncedo kakhulu kukuba kunzima kakhulu ukulungisa iindibano zePCB ezenziwe kusetyenziswa le ndlela.Oku kungenxa yokuba isiphaluka sinzima kakhulu kunezinye iindlela.
Oku kungasentla lulwazi malunga PCB endifuna ukwabelana nawe.Indibano ye-SMT ngoku yeyona ndlela yokuqhubela phambili yendibano yePCB.Ngolwazi oluthe kratya malunga noku, nceda uqhagamshelane nathi.
