Iibhodi zeesekethe eziprintiweyo zisetyenziswa ngokubanzi kwii-electronics ezahlukeneyo kunye nobuchwepheshe, okwenza zibe zixhobo ezibaluleke kakhulu. Nokuba yifowuni ephathwayo, ikhompyuter okanye umatshini onzima, uya kufumanisa ukuba i-pcb inoxanduva lomsebenzi wesixhobo. Ukuba ibhodi yesekethe eprintiweyo ineziphene okanye iingxaki zokuvelisa, inokubangela ukuba imveliso yokugqibela ingasebenzi kakuhle kwaye ibangele ukuphazamiseka. Phantsi kwezi meko, abavelisi kuya kufuneka bakhumbule ezi zixhobo kwaye bachithe ixesha elininzi kunye nezixhobo zokulungisa isiphene.
Esi sesinye sezizathu eziphambili zokuba kutheni uninzi lwabaphuhlisi baphendukela kubayili be-pcb kunye nabavelisi bokwenza kunye novavanyo lobungcali.
Kutheni kufuneka ibhodi pcb ivavanywe?
Inqanaba lovavanyo lokwenziwa kwePCB sesinye sezona zigaba zibalulekileyo. Ukuba ngaba awuvavanyi ibhodi pcb yakho, kusenokubakho ezinye iimpazamo kunye neengxaki ukuba zingahoywa ngexesha lemveliso. Ezi ngxaki zinokuthi ekugqibeleni zikhokelele ekungaphumeleni kwebala kunye neziphene. Ukunciphisa ithuba lokungaphumeleli kunye nokugcina ukwaneliseka kwabathengi, kubalulekile ukwenza iinkqubo zokuvavanya ukuqinisekisa ukuba iibhodi zeesekethe eziprintiweyo kunye namacandelo asebenza ngokupheleleyo. Kukho inkqubo yokuvavanya kwisigaba sokuvelisa, esikuvumela ukuba uchonge iimpazamo kunye neengxaki kwangaphambili kunokuba kwinqanaba lokugqibela lokuvavanya.
Uyilo lwebhodi yesekethe eprintiweyo kunye neenkampani zokuvelisa zihlala zinenkqubo yovavanyo ecokisekileyo yokuqinisekisa ukuba ibhodi yesekethe eprintiweyo yokugqibela ikumgangatho ophezulu.
Uvavanyo lwecandelo lePCB
Isigaba sovavanyo sikholisa ukuba sisigaba esicokisekileyo kwaye sidinga ingqalelo enkulu kwiinkcukacha. Ibhodi pcb yenziwe ngamacandelo ahlukeneyo anzima. Oku kunokubandakanya ii-capacitors, resistors, transistors, diodes kunye ne-fuses. Lawa ngamacandelo aphambili ekufuneka avavanyelwe naziphi na iimpawu zokungahambi kakuhle kunye nokungasebenzi kakuhle.
I-Capacitors-Capacitors zixhobo ezincinci zombane ezigcina amandla ngendlela ye-electrostatic fields. I-Capacitors inoxanduva lokuthintela ukuhamba kwangoku ngokuthe ngqo kunye nokwenza ukuba kube lula ukugcina ngoku ngokungathanga ngqo ngelixa ugcina amandla. Ukuvavanya ezi capacitors, i-voltage isetyenziswa ukuvavanya ukuba ingaba isebenza njengoko kufuneka. Ngaphandle koko, iziphumo ezahlukeneyo zingavela, ezibonisa iisekethe ezimfutshane, ukuvuza, okanye ukungaphumeleli kwe-capacitor.
I-Diode-A diode sisixhobo esincinci sombane esinokuhambisa okwangoku kwicala elinye. Xa ihambisa okwangoku kwicala elinye, ivimba umva wangoku. I-diode sisixhobo esibuthathaka kakhulu, kwaye ukuyivavanya kufuna inkathalo. Kucetyiswa ukuba udibane neengcali ngaphambi kokuvavanya iindawo ezinobuzaza ukukhusela umonakalo
Resistor-Resistor yenye amacandelo eziphambili pcb ibhodi. Ezi zixhobo zombane zincinci zineetheminali ezimbini ezenza i-voltage ukusuka kweli langoku. Ukuvavanya oku kuxhathisa, ungasebenzisa i-ohmmeter. Emva kokuba ukuchasana kuhlukanisiwe, ungasebenzisa i-multimeter yedijithali kwaye udibanise izikhokelo zokuchasana nokuvavanya. Ukuba ufundo luphezulu kakhulu, lunokuba kungenxa ye-resistor evulekileyo.
Ekubeni ibhodi ye-pcb iqulunqwe ngamacandelo ombane anzima, kubaluleke kakhulu ukuvavanya ukuba ibhodi ye-pcb inazo naziphi na iimpazamo okanye iimpazamo ezinokubangela ukuba ibhodi yesekethe ingasebenzi kakuhle. Icandelo ngalinye kufuneka libekwe esweni kwaye livavanywe ukugcina ibhodi yesekethe esebenzayo eprintiweyo ikwindawo yayo epheleleyo
Fastline Circuits Co.,Limited.ithatha le miba mithathu ingentla njengamanqaku okuphumelela, kwaye abathengi banokukhetha ngokulula umenzi ofanelekileyo. Kwangaxeshanye, kufuneka sinikele ingqalelo kunxibelelwano kunye notshintshiselwano kunye nabavelisi, ukuze la macala mabini enze "inzuzo ngokufanayo kwaye win-win", kwaye ngcono ukukhuthaza intsebenziswano iprojekthi imveliso.
