1. Ukulungiselela
Kubandakanya ukulungiswa kwezingxenye zemitapo yolwazi kanye nezinhlelo.Ngaphambi kwedizayini ye-PCB, qala ngokulungiselela ilabhulali yengxenye ye-SCH eyisikimu kanye nelabhulali yephakheji yengxenye ye-PCB.
Ilabhulali yephakheji yengxenye ye-PCB isungulwa kangcono ngonjiniyela ngokusekelwe kulwazi losayizi ojwayelekile wedivayisi ekhethiwe.Empeleni, qala ngokusungula umtapo wolwazi wephakheji yengxenye ye-PC, bese usungula umtapo wolwazi wengxenye ye-SCH.
Umtapo wezincwadi wephakeji wengxenye ye-PCB ufuna kakhulu, uthinta ngqo ukufakwa kwe-PCB;Izidingo zomtapo wolwazi wengxenye ye-SCH zikhululekile uma kuqhathaniswa, kodwa naka incazelo yezakhiwo ezinhle zamaphini kanye nokuxhumana nomtapo wezincwadi wengxenye ye-PCB.
2. PCB isakhiwo design
Ngokusho kosayizi webhodi kunqunyiwe kanye nokuma kwemishini okuhlukahlukene, indawo yokuklama ye-PCB ukudweba ifreyimu yebhodi le-PCB, kanye nezidingo zokubeka ukubeka izixhumi ezidingekayo, okhiye / amaswishi, izimbobo zezikulufu, izimbobo zokuhlanganisa, njll.
Cabangela ngokugcwele futhi unqume indawo yezintambo nendawo okungezona izintambo (njengokuthi ingakanani imbobo yesikulufu ingeyendawo okungezona izintambo).
3. PCB layout design
Idizayini yesakhiwo ukubekwa kwamadivayisi kuhlaka lwe-PCB ngokuhambisana nezidingo zokuklama.Khiqiza ithebula lenethiwekhi ethuluzini lesikimu (Design→CreateNetlist), bese ungenisa ithebula lenethiwekhi kusofthiwe ye-PCB (Design→ImportNetlist).Ngemuva kokungenisa ngempumelelo kwethebula lenethiwekhi kuzoba khona ngemuva kwesoftware, ngokusebenzisa umsebenzi Wokubeka kungaba wonke amadivaysi abizwe, phakathi kwezikhonkwane ezinamasu ezindizayo axhunyiwe, khona-ke ungakwazi ukuklama isakhiwo sedivayisi.
Idizayini yesakhiwo se-PCB iyinqubo yokuqala ebalulekile kuyo yonke inqubo yokuklama ye-PCB, ibhodi le-PCB eliyinkimbinkimbi, ngcono ukwakheka kungathinta ngqo ukusebenziseka kalula kwezintambo zakamuva.
Idizayini yesakhiwo incike kumakhono ayisisekelo wesekethe womklami webhodi lesifunda nolwazi lokuklama, umklami webhodi uyizinga eliphakeme lezidingo.Abaklami bebhodi lesekethe abancane basenolwazi olungajulile, balungele ukwakheka kwemojuli encane noma ibhodi lonke linzima kakhulu imisebenzi yokuklama i-PCB.
4. PCB izintambo design
Idizayini yokufaka izintambo ze-PCB ingumthwalo omkhulu womsebenzi kuyo yonke inqubo yokuklama ye-PCB, ethinta ngokuqondile ukusebenza kwebhodi le-PCB.
Enqubweni yokuklama ye-PCB, izintambo ngokuvamile zinezindawo ezintathu.
Okokuqala, indwangu ngokusebenzisa, okuyinto eyisisekelo kakhulu imfuneko yokungena for PCB design.
Okwesibili, ukusebenza kukagesi ukuhlangabezana, okuyisilinganiso sokuthi ibhodi le-PCB lifaneleka yini, ngemva komugqa ngokusebenzisa, lilungise ngokucophelela i-wiring, ukuze likwazi ukufeza ukusebenza kahle kagesi.
Nakulokhu kucocekile futhi kuhle, izintambo ezingahlelekile, ngisho noma ukusebenza kukagesi kuzoletha ukuphazamiseka okukhulu ekwenzeni kahle kamuva kwebhodi nokuhlolwa nokugcinwa, izidingo zezintambo zicocekile futhi zicocekile, azikwazi ukuphambana ngaphandle kwemithetho nemithethonqubo.
5. Ukwenza kahle izintambo nokubekwa kwesikrini sikasilika
“Umklamo we-PCB awuwona ongcono kakhulu, ungcono kuphela”, “Umklamo we-PCB uwubuciko obunesici”, ikakhulukazi ngenxa yokuthi i-PCB design ukufeza izidingo zokuklama izici ezihlukahlukene zehadiwe, futhi izidingo zomuntu ngamunye zingase zibe nokungqubuzana phakathi kwezinhlanzi nebhere. i-paw ayikwazi ukuba kokubili.
Isibonelo: iphrojekthi ye-PCB yokuklama emva komklami webhodi ukuhlola isidingo sokuklama ibhodi le-6-layer, kodwa i-hardware yomkhiqizo ukuze kucatshangelwe izindleko, izidingo kufanele zenziwe njengebhodi le-4-layer, bese kuphela ngezindleko ze- ungqimba lomhlabathi lwesivikelo sesignali, okuholela ekwandeni kwe-crosstalk yesignali phakathi kwezingqimba zezintambo eziseduze, ikhwalithi yesiginali izoncishiswa.
Umuzwa wokuklama ojwayelekile uthi: lungiselela isikhathi sezintambo siphindwe kabili kunesokuqala izintambo.Ukulungiswa kwezintambo ze-PCB kuqediwe, isidingo sokucutshungulwa kwangemuva, ukucutshungulwa okuyinhloko indawo yebhodi ye-PCB yelogo yesikrini sikasilika, ukuklanywa kongqimba olungezansi lwezinhlamvu zesikrini sikasilika kudingeka kwenziwe ukucutshungulwa kwesibuko, ukuze kungenziwa. phambanisa nongqimba olungaphezulu lwesikrini sikasilika.
6. Inethiwekhi ye-DRC isheke kanye nokuhlola isakhiwo
Ukulawulwa kwekhwalithi kuyingxenye ebalulekile yenqubo yokuklama ye-PCB, izindlela ezijwayelekile zokulawula ikhwalithi zihlanganisa: ukuzihlola ngokwakho, ukuklama ukuhlola okuhlangene, imihlangano yokubuyekezwa kochwepheshe, ukuhlolwa okukhethekile, njll.
Izakhi zohlelo nesakhiwo somdwebo ziyizidingo eziyisisekelo zokuklama, ukuhlola kwenethiwekhi ye-DRC kanye nokuhlolwa kwesakhiwo ukuqinisekisa ukuthi idizayini ye-PCB ukuze ihlangabezane nohlu lwe-network oluyisikimu kanye nezakhi zesakhiwo somdwebo wezimo ezimbili zokufakwayo.
Abaklami bebhodi elivamile bazoba nohlu lwabo lokuhlola ikhwalithi yedizayini eqoqiwe, oluyingxenye yokufakiwe okuvela enkampanini noma ezicacisweni zomnyango, enye ingxenye evela kuzifinyezo zabo zokuhlangenwe nakho.Ukuhlola okukhethekile kufaka phakathi idizayini yesheke le-Valor kanye nokuhlola kwe-DFM, lezi zingxenye ezimbili zokuqukethwe ziphathelene ne-PCB design okukhiphayo okuphuma emuva kokucubungula ifayela lomdwebo wokukhanya.
7. PCB board making
Ekucubunguleni okusemthethweni kwe-PCB ngaphambi kwebhodi, umklami webhodi lesifunda udinga ukuxhumana nefekthri yebhodi lokunikezela ye-PCB A PE, ukuze aphendule umenzi ebhodini le-PCB izinkinga zokuqinisekisa ukucubungula.
Lokhu kuhlanganisa, kodwa akukhawulelwe kulokhu: ukukhethwa kohlobo lwebhodi le-PCB, ukulungiswa kwesikhala somugqa wobubanzi bomugqa wesendlalelo somugqa, ukulungiswa kokulawulwa kwe-impedance, ukulungiswa kokuqina kwe-PCB lamination, inqubo yokucubungula ukwelashwa kwendawo, ukulawula ukubekezelelana kwembobo kanye namazinga okulethwa.
