1. Ukulungiselela
Kubandakanywa ulungiselelo lwamathala eencwadi amacandelo kunye neschematics.Phambi koyilo lwePCB, lungiselela kuqala ithala leencwadi lecandelo leSCH elicwangcisiweyo kunye nethala leencwadi lecandelo lePCB.
Ithala leencwadi lepakethe yecandelo lePCB limiselwa ngcono ziinjineli ngokusekelwe kulwazi lobungakanani obuqhelekileyo besixhobo esikhethiweyo.Ngokomgaqo, qala ngokuseka ithala leencwadi lecandelo lePC, emva koko umisele ithala leencwadi lecandelo leSCH.
Ithala leencwadi lepakethe yecandelo lePCB lifuna kakhulu, lichaphazela ngqo ukufakelo lwePCB;Iimfuno zethala leencwadi le-SCH ezicwangcisiweyo zecandelo lethala leencwadi zikhululekile noko, kodwa nikela ingqalelo kwinkcazo yeepropathi ezilungileyo zephini kunye nembalelwano kunye nethala leencwadi lecandelo lePCB.
2. Uyilo lwesakhiwo sePCB
Ngokwesayizi yebhodi iye yamiselwa kunye neendawo ezahlukeneyo zokubeka oomatshini, indawo yoyilo lwePCB ukuzoba isakhelo sebhodi yePCB, kunye neemfuno zokubeka ukubeka iziqhagamshelo ezifunekayo, izitshixo / iiswitshi, imingxuma yezikrufu, imingxuma yendibano, njl.
Qwalasela ngokupheleleyo kwaye umisele indawo yokubiyela kunye nendawo engeyiyo yocingo (efana nokuba yimalini ejikeleze umngxuma wesikrufu kwindawo engeyiyo yocingo).
3. uyilo loyilo lwePCB
Uyilo loyilo kukubekwa kwezixhobo kwisakhelo sePCB ngokuhambelana neemfuno zoyilo.Yenza itafile yenethiwekhi kwisixhobo sokucwangcisa (uYilo→CreateNetlist), kwaye emva koko ungenise itafile yenethiwekhi kwisoftware yePCB (Design→ImportNetlist).Emva kokungeniswa ngempumelelo kwetheyibhile yenethiwekhi iya kubakho kwimvelaphi yesoftware, ngokusebenza kokuBekwa kungabizwa zonke izixhobo, phakathi kwezikhonkwane ezineengcebiso eziphaphazelayo eziqhagamshelweyo, ngoko ke unokuyila uyilo lwesixhobo.
Uyilo loyilo lwePCB yinkqubo yokuqala ebalulekileyo kuyo yonke inkqubo yoyilo lwePCB, ibhodi yePCB entsonkothileyo, ngcono ukwakheka kunokuchaphazela ngokuthe ngqo ukukhululeka kokuphunyezwa kocingo lwamva.
Uyilo loyilo luxhomekeke kwizakhono ezisisiseko zomyili webhodi yesekethe kunye namava oyilo, umyili webhodi ukwinqanaba eliphezulu leemfuno.Abayili bebhodi yesekethe abancinci basengamava angekho nzulu, alungele uyilo loyilo lwemodyuli encinci okanye ibhodi iyonke ayinzima kangako yimisebenzi yoyilo lwePCB.
4. Uyilo lweingcingo zePCB
Uyilo locingo lwePCB ngowona msebenzi mkhulu kuyo yonke inkqubo yoyilo lwePCB, echaphazela ngokuthe ngqo ukusebenza kwebhodi yePCB.
Kwinkqubo yoyilo lwePCB, iingcingo zineendawo ezintathu.
Okokuqala, ilaphu nge, eyona isisiseko imfuneko yokungena kuyilo PCB.
Okwesibini, ukusebenza kombane ukuhlangabezana, nto leyo umlinganiselo ukuba ibhodi PCB imigangatho abafanelekileyo, emva kokuba umgca ngokusebenzisa, uhlengahlengiso ngocoselelo iingcingo, ukuze ikwazi ukufezekisa ukusebenza kakuhle kombane.
Kwakhona icocekile kwaye intle, iingcingo ezingalungelelanisiweyo, nokuba ukusebenza kombane kuya kuzisa inkxwaleko enkulu ekuphuculeni kamva kwebhodi kunye novavanyo kunye nokugcinwa, iimfuno zocingo zicocekile kwaye zicocekile, azinakugqithwa ngaphandle kwemithetho nemimiselo.
5. Ukulungiswa kweengcingo kunye nokubekwa kwesikrini sesilika
“Uyilo lwePCB alulona lungcono, lungcono kuphela”, “Uyilo lwePCB lubugcisa obuneziphene”, ikakhulu ngenxa yokuba uyilo lwePCB ukufezekisa iimfuno zoyilo lwemiba eyahlukeneyo yehardware, kwaye iimfuno zomntu ngamnye zinokuba zingquzulwano phakathi kwentlanzi kunye nebhere. i-paw ayikwazi ukuba zombini.
Umzekelo: iprojekthi yoyilo lwe-PCB emva kokuba umyili webhodi avavanye imfuneko yokuyila ibhodi ye-6-layer, kodwa i-hardware yemveliso yoqwalaselo lweendleko, iimfuno kufuneka ziyilwe njengebhodi ye-4-layer, emva koko kuphela ngeendleko zexabiso. Umaleko womhlaba wekhuselo lophawu, okukhokelela ekunyukeni kophawu lwe-crosstalk phakathi kwee-wire layers ezikufutshane, umgangatho womqondiso uya kuncitshiswa.
Amava oyilo oluqhelekileyo kukuba: ukulungelelanisa ixesha lokudibanisa liphindwe kabini ixesha locingo lokuqala.PCB wiring optimization igqityiwe, imfuno post-processing, processing ephambili ibhodi PCB umphezulu logo yesilika-screen, uyilo umaleko ezantsi abalinganiswa silk-screen kufuneka ukwenza isipili processing, ukuze kungabikho. ukubhida umaleko ophezulu wesilika-screen.
6. Itshekhi ye-DRC yothungelwano kunye nokujonga isakhiwo
Ukulawulwa komgangatho yinxalenye ebalulekileyo yenkqubo yokuyila i-PCB, iindlela eziqhelekileyo zokulawula umgangatho zibandakanya: ukuzihlola ukuzihlola, ukuyila ukuhlola ngokubambisana, iintlanganiso zokuphononongwa kweengcali, ukuhlolwa okukhethekileyo, njl.
Izinto ezicwangcisiweyo kunye nolwakhiwo lomzobo zezona mfuno zoyilo ezisisiseko, uthungelwano lwe-DRC jonga kunye nolwakhiwo lokukhangela kukuqinisekisa ukuba uyilo lwePCB ukuhlangabezana noluhlu olucwangcisiweyo kunye nezakhiwo zomzobo wemiqathango emibini yokufaka.
Abaqulunqi bebhodi ngokubanzi baya kuba noluhlu lwabo oluqokelelweyo lokujonga umgangatho woyilo, oluyinxalenye yamangenelo avela kwinkampani okanye kwiinkcukacha zesebe, enye inxalenye evela kushwankathelo lwamava abo.Iitshekhi ezikhethekileyo ziquka uyilo lwetshekhi yeValor kunye ne-DFM yokukhangela, ezi nxalenye zimbini zomxholo zixhalabile malunga noyilo lwePCB oluphumayo emva kokuphela kokucubungula ukukhanya kwefayile yokudweba.
7. ukwenza ibhodi PCB
Kwinkqubo esesikweni ye-PCB phambi kwebhodi, umyili webhodi yesekethe kufuneka anxibelelane ne-PCB A ibhodi yobonelelo lwefektri PE, ukuphendula umenzi kwibhodi ye-PCB yokuqinisekisa imicimbi.
Oku kubandakanya, kodwa kungaphelelanga apho: ukhetho lwebhodi yebhodi ye-PCB, ukulungiswa kwesithuba somgca wobubanzi bomgca womgca womgca, ukulungiswa kokulawulwa kwe-impedance, ukulungiswa kwe-PCB lamination ubukhulu, inkqubo yokucubungula unyango, ulawulo lokunyamezela umngxuma kunye nemigangatho yokuhanjiswa.
