Njenge PCB esetyenziswa zizixhobo ezahluka-hlukeneyo ze-elektroniki ziya ziba ngakumbi nangakumbi, ukufumana isiphoso se-PCB sasemuva ngesandla akunzima nje kuphela kodwa kukwanokuthenjwa okuphantsi. Uvavanyo lwe-AUTOMATIC lwe-PCB engasemva esekwe kwi-PLD efakwe kweli phepha inokuphucula ukusebenza ngokukuko kunye nokuqinisekisa ukuthembeka kokufunyanwa.

Ngophuhliso olukhawulezayo lwetekhnoloji ye-elektroniki, isetyenziswa ngokubanzi kwiindidi ezahlukeneyo zokuveliswa kwezixhobo ze-elektroniki zebhodi yesekethe eprintiweyo (i-PCB) inyuke kakhulu, abasebenzi bezobuchwephesha kufuneka bakhawuleze babone umva kwisekethe emfutshane, isiphoso esivulekileyo sesekethe okanye ukulungisa izixa ezigqithileyo ukumelana, ukuba ukuthembela ekufumanekeni kuyinkimbinkimbi kakhulu, kwaye ukuthembeka kusezantsi, ke ibhodi yesekethe ibuyile kakhulu kwimfuno yovavanyo oluzenzekelayo. Kweli phepha, indlela yenkqubo yovavanyo oluzenzekelayo yePCP backplane esekwe kwi-EPM7128 yolawulo lokukhetha izinto ezininzi kwi-ADG732 kucetywayo, kwaye ukuphunyezwa kwayo kunikiwe. Kuyangqinwa ukuba indlela yovavanyo iyakhawuleza kwaye iyasebenza emva kokufakwa kuvavanyo lwenqanawa ye-PCB.

Ukwenziwa kwenkqubo yezixhobo

Inkqubo yolwakhiwo lomvavanyi oluzenzekelayo ibonisiwe kwi Umzobo 1, oqukethe imicrocomputer, ikhadi lebhasi le-USB ibhasi ye-DIO, ibhloko yolawulo lwe-PLD, iswitshi yokukhetha iindlela ezininzi, indawo yovavanyo njalo njalo.Inkqubo inokuvavanya ngokukhawuleza ukuvulwa kunye nokufutshane kweempazamo zesekethe zebhodi yangasemva enye, ephindwe kabini kunye neyohlukeneyo ye-PCB.

IiMicrocomputer azinazo iimfuno ezizodwa, kwaye ngokubanzi zinokusebenzisa iikhompyuter eziqhelekileyo. Inkqubo yothungelwano yamkela itemplate yolawulo lwe-USB-7802ADIO yexabiso eliphantsi eveliswe nguMlinganiso weHongtop kunye noLawulo lweTekhnoloji yeComputer, LTD. Igalelo kunye nemveliso yombane ngu-0 ~ 5V, ngokuhambelana nebhasi ye-USB + 5V esemgangathweni. I-Usb-7802a yindawo engama-32 yedijithali ye-TTL yenqanaba lokufaka / ukuphuma kwebhodi, enezibuko ezi-4 ezi-8 zedigital yokufaka kunye ne-4 8-bit yedijithali yokuphuma kwamazibuko e-latch, igalelo elipheleleyo lama-32 kunye neziphumo ezingama-32; Inika i-win95 / 98/2000 / NT phantsi kwenkqubo yovavanyo kunye nenkqubo yekhonkco enamandla (i-DLL).Kuba ibhasi ye-USB, iprotocol ye-USB yabela ngokuzenzekelayo idilesi yesiseko sebhodi.
