Xa uthetha ngeebhodi zesekethe eziprintiweyo, ii-novices zihlala zibhidanisa "izicwangciso zePCB" kunye "neefayile zoyilo zePCB", kodwa enyanisweni zibhekisa kwizinto ezahlukeneyo.Ukuqonda umahluko phakathi kwabo sisitshixo sokwenza ngempumelelo ii-PCBs, ukuze uvumele abaqalayo ukuba benze oku ngcono, eli nqaku liza kwaphula umahluko ophambili phakathi kwe-PCB schematics kunye noyilo lwePCB.
Yintoni iPCB
Phambi kokungena kumahluko phakathi koyilo kunye noyilo, yintoni ekufuneka iqondwe ukuba yintoni iPCB?
Ngokusisiseko, kukho iibhodi zesekethe eziprintiweyo ngaphakathi kwezixhobo zombane, ezikwabizwa ngokuba ziibhodi zesekethe eziprintiweyo.Le bhodi yesekethe eluhlaza eyenziwe ngentsimbi exabisekileyo idibanisa onke amacandelo ombane wesixhobo kwaye yenza ukuba isebenze ngokuqhelekileyo.Ngaphandle kwePCB, izixhobo zombane aziyi kusebenza.
Isicwangciso sePCB kunye noyilo lwePCB
I-PCB schematic luyilo olulula lwesekethe enamacala amabini ebonisa ukusebenza kunye noqhagamshelwano phakathi kwamacandelo ahlukeneyo.Uyilo lwePCB luyilo olunamacala amathathu, kwaye indawo yamacandelo iphawulwe emva kokuba isekethe iqinisekisiwe ukusebenza ngokuqhelekileyo.
Ke ngoko, iskimu sePCB yinxalenye yokuqala yokuyila ibhodi yesekethe eprintiweyo.Lo ngumboniso womzobo osebenzisa iisimboli ekuvunyelwene ngazo ukuchaza uqhagamshelo lwesekethe, nokuba lubhalwe okanye lukwimo yedatha.Ikwakhuthaza amacandelo ukuba asetyenziswe kunye nendlela adityaniswa ngayo.
Njengoko igama licebisa, iskimu sePCB sisicwangciso kunye neplani.Ayibonisi apho amacandelo aya kubekwa khona ngokuthe ngqo.Endaweni yoko, iskimu sichaza indlela i-PCB eya kuthi ekugqibeleni ifezekise ngayo uqhagamshelo kwaye yenza inxenye ephambili yenkqubo yokucwangcisa.
Emva kokuba iplani igqityiwe, inyathelo elilandelayo luyilo lwePCB.Uyilo luyilo okanye umboniso obonakalayo weskim sePCB, kubandakanywa noyilo lwemikhondo yobhedu kunye nemingxuma.Uyilo lwePCB lubonisa indawo yamacandelo akhankanywe ngasentla kunye noqhagamshelwano lwawo kubhedu.
Uyilo lwePCB linqanaba elinxulumene nokusebenza.Iinjineli zakha amacandelo okwenyani ngokwesiseko soyilo lwePCB ukuze bakwazi ukuvavanya ukuba isixhobo sisebenza kakuhle na.Njengoko besesitshilo ngaphambili, nabani na kufuneka abe nako ukuqonda schematic PCB, kodwa akukho lula ukuqonda umsebenzi wayo ngokujonga prototype.
Emva kokuba ezi zigaba zimbini zigqityiwe, kwaye wanelisekile ngokusebenza kwePCB, kufuneka uyiphumeze ngomenzi.
Izinto zesicwangciso sePCB
Emva kokuqonda ngokucacileyo umahluko phakathi kwezi zimbini, makhe sijonge ngakumbi kwizinto ze-PCB schematic.Njengoko sitshilo, lonke unxibelelwano luyabonakala, kodwa kukho izilumkiso ekufuneka uzigcine engqondweni:
Ukuze ukwazi ukubona ukudibanisa ngokucacileyo, akwenziwanga ukukala;kuyilo PCB, basenokuba kakhulu omnye komnye
Olunye unxibelelwano lunokuwela omnye komnye, nto leyo eneneni ayinakwenzeka
Amanye amakhonkco anokuba kwelinye icala loyilo, anophawu olubonisa ukuba adityanisiwe
Le PCB "iplani" inokusebenzisa iphepha elinye, amaphepha amabini okanye amaphepha ambalwa ukuchaza wonke umxholo ekufuneka ubandakanywe kuyilo.
Into yokugqibela ekufuneka uyiqaphele kukuba i-schematics enzima ngakumbi inokudityaniswa ngomsebenzi ukuphucula ukufundeka.Ukucwangcisa ukudibanisa ngale ndlela akuyi kwenzeka kwinqanaba elilandelayo, kwaye i-schematics ngokuqhelekileyo ayihambelani noyilo lokugqibela lwemodeli ye-3D.
Izinto zoyilo zePCB
Lixesha lokungena nzulu kwizinto zeefayile zoyilo zePCB.Ngeli nqanaba, sitshintshe ukusuka kwiiplani ezibhaliweyo ukuya kwimiboniso ebonakalayo eyenziwe kusetyenziswa i-laminate okanye i-ceramic materials.Xa kufuneka isithuba esixineneyo ngokukodwa, ezinye izicelo ezinzima ngakumbi zifuna ukusetyenziswa kweePCB ezibhetyebhetye.
Umxholo wefayile yoyilo lwePCB ulandela iplani esekwe yinkqubo yokuqukuqela, kodwa, njengoko bekutshiwo ngaphambili, ezi zimbini zahluke kakhulu ngenkangeleko.Sixoxe ngezicwangciso zePCB, kodwa nguwuphi umahluko onokubonwa kwiifayile zoyilo?
Xa sithetha ngeefayile zoyilo zePCB, sithetha ngemodeli ye-3D, ebandakanya ibhodi yesekethe eprintiweyo kunye neefayile zoyilo.Zingaba ngumaleko omnye okanye iileya ezininzi, nangona iileya ezimbini zixhaphake kakhulu.Sinokubona umahluko phakathi kwezicwangciso zePCB kunye neefayile zoyilo zePCB:
Onke amacandelo anobungakanani kwaye abekwe ngendlela efanelekileyo
Ukuba amanqaku amabini akufuneki adityaniswe, kufuneka ajikeleze okanye atshintshele komnye umaleko wePCB ukunqanda ukuwela omnye komnye kumaleko afanayo.
Ukongeza, njengoko besithetha ngokufutshane malunga, uyilo lwePCB lunika ingqwalasela ngakumbi ekusebenzeni kokwenyani, kuba oku kwinqanaba elithile linqanaba lokuqinisekisa imveliso yokugqibela.Ngeli xesha, ukusebenza koyilo kufuneka kusebenze ngokwenene, kwaye iimfuno zomzimba zebhodi yesekethe eprintiweyo kufuneka ziqwalaselwe.Ezinye zazo ziquka:
Ingaba izithuba zamacandelo zivumela njani ukwabiwa kobushushu okwaneleyo
Izihlanganisi emphethweni
Ngokuphathelele kwimiba yangoku kunye nobushushu, kufuneka ukuba zityebe kangakanani na iitreyi ezahlukeneyo
Ngenxa yokuba izithintelo zomzimba kunye neemfuno zithetha ukuba iifayile zoyilo zePCB zihlala zibonakala zahluke kakhulu kuyilo lweskimu, iifayile zoyilo ziquka umaleko wesikrini sesilika.Umaleko wesikrini sesilika ubonisa iileta, amanani kunye neesimboli ukunceda iinjineli ukuba zihlangane kwaye zisebenzise ibhodi.
Kufunwa ukusebenza njengoko kucwangcisiwe emva kokuba onke amacandelo ehlanganiswe kwibhodi yesekethe eprintiweyo.Ukuba akunjalo, kufuneka uzobe ngokutsha.
