Imisebenzi yesendlalelo ngasinye ebhodini le-Bare PCB

Abaningiibhodi le-PCB elingenaluthoabathanda ukuklama, ikakhulukazi abaqalayo, abanakho ukuqonda okwanele kwezigaba ezihlukahlukenenqunuPCB board design, futhi abazi imisebenzi yabo kanye nokusetshenziswa.Nansi incazelo ehlelekile yakho:

1. Isendlalelo esiwumshini ukubonakala kwayo yonke ibhodi ye-PCB engenalutho ukuze kuphothulwe ngokusebenza.Eqinisweni, uma sikhuluma ngongqimba lwemishini, sisho ukuma nesakhiwo sebhodi le-PCB elingenalutho.Ingase futhi isetshenziselwe ukusetha ubukhulu bebhodi, izimpawu zedatha, amamaki okuqondanisa, imiyalelo yokuhlanganisa kanye nolunye ulwazi lwemishini.Lolu lwazi luyahlukahluka kuye ngezidingo zenkampani yokuklama nomaUmkhiqizi we-PCB.Ngaphezu kwalokho, izendlalelo zomshini zingaxhunywa kwezinye izendlalelo ukuze kukhishwe isibonisi ndawonye.

2. Gcina ngaphandle ungqimba (ungqimba lwezintambo olungavunyelwe), olusetshenziselwa ukuchaza indawo lapho izingxenye nezintambo zingabekwa khona ngempumelelo ebhodini le-PCB elingenalutho.Indawo evaliwe idwetshwa kulesi sendlalelo njengendawo esebenzayo yomzila, futhi ukubekwa okuzenzakalelayo nomzila ngeke kwenziwe ngaphandle kwale ndawo.Isendlalelo sezintambo esenqatshelwe siwumngcele lapho sichaza ithusi lezici zikagesi, okusho ukuthi, ngemva kokuchaza ungqimba lwezintambo olunqatshelwe kuqala, enqubweni yokufaka izintambo ezilandelayo, akunakwenzeka ukuthi izintambo ezinezici zikagesi zidlule okwenqatshelwe. izintambo.Umngcele wesendlalelo uvame ukusetshenziswa ukusebenzisa isendlalelo se-Keep out njengesendlalelo somshini.Le ndlela empeleni ayilungile, ngakho-ke kunconywa ukuthi uyihlukanise, ngaphandle kwalokho imboni yebhodi izokunikeza izinguquko zesibaluli ngaso sonke isikhathi lapho ukhiqiza.

3. Ungqimba lwesiginali: Ungqimba lwesiginali lusetshenziswa kakhulu ukuhlela izintambo ebhodini le-PCB elingenalutho.Kubandakanya ungqimba olungaphezulu (ungqimba olungaphezulu), ungqimba olungezansi (ungqimba olungezansi) no-30 MidLayer (ungqimba oluphakathi).Amadivayisi abekwe phezu kwezendlalelo eziPhezulu nezingaphansi, futhi izendlalelo zangaphakathi ziyahanjiswa.

4. Okunamathiselwe phezulu kanye nokunamathisela phansi yizingqimba ze-stencil zephedi eliphezulu nangaphansi, ezinosayizi ofanayo namaphedi.Lokhu kungenxa yokuthi singasebenzisa lezi zingqimba ezimbili ukwenza ama-stencil lapho senza i-SMT.Sisanda kugubha umgodi olingana nephedi enethini, sabe sesibeka isembozo sensimbi yensimbi ebhodini le-PCB elingenalutho, futhi saxubha unamathisela we-solder ngokulinganayo ngebhulashi eline-solder unama.

5. I-Top Solder ne-Bottom Solder Lena imaski ye-solder ukuvimbela ukumbozwa kwamafutha aluhlaza.Sivame ukuthi "ukuvula iwindi".Ithusi elivamile noma iminonjana imbozwe ngamafutha aluhlaza ngokuzenzakalelayo.Uma simboza ngokulinganayo isendlalelo semaski ye-solder Uma siphathwa, sizovimbela uwoyela oluhlaza ekusimbozeni futhi siveze ithusi.

6. Isendlalelo sendiza yangaphakathi (amandla angaphakathi/ungqimba lomhlabathi): Lolu hlobo lwesendlalelo lusetshenziselwa kuphela amabhodi anezingqimba eziningi, ikakhulukazi ukuhlela izintambo zikagesi nemigqa yaphansi.Siwabiza ngamabhodi anezingqimba ezimbili, amabhodi anezingqimba ezine, namabhodi anezingqimba eziyisithupha, ngokuvamile abhekisela enanini lezingqimba zesignali namandla angaphakathi/izindiza eziphansi.

7. Isendlalelo sesikrini sikasilika: Isendlalelo sesikrini sikasilika sisetshenziselwa kakhulu ukubeka ulwazi lokuphrinta, olufana nohlaka nokulebula kwezingxenye, izinhlamvu zezichasiselo ezihlukahlukene, njll. I-Altium inikeza Imbondela Ephezulu kanye Nembondela Ezansi izendlalelo ezimbili zesikrini sikasilika, ngokulandelana, ukubeka ifayela lesikrini sikasilika esiphezulu. kanye nefayela lesikrini sikasilika eliphansi.

8. Izendlalelo eziningi: Amaphedi kanye nama-vias angena ebhodini le-PCB elingenalutho kufanele lingene kulo lonke ibhodi le-PCB elingenalutho futhi asungule uxhumo lukagesi ngezendlalelo zephethini yokuqhuba.Ngakho-ke, isistimu imise ngokukhethekile isendlalelo esingabonakali—izendlalelo eziningi.​ Ngokuvamile, amaphedi nama-vias ahlelwa ezendlalelo eziningi.Uma lesi singqimba sivaliwe, amaphedi nama-vias awakwazi ukuboniswa.

9. I-Drill Drawing (ungqimba lokubhoboza): Isendlalelo sokumba sihlinzeka ngolwazi lokubhola ohlelweni lokukhiqiza lwebhodi le-PCB elingenalutho (njengamaphedi, ama-vias adinga ukubhola).I-Altium ihlinzeka ngegridi ye-Drill (imephu yeziqondiso zokubhoboza) kanye nomdwebo we-Drill (imephu yokubhola) izendlalelo ezimbili zokumba.

Ngemuva kokuthi ukwakhiwa kwebhodi le-PCB elingenalutho sekuqediwe, i-prototype yebhodi ye-PCB engenalutho idinga ukwenziwa, futhi kubalulekile ukukhetha okungenalutho okuhle.I-PCB board prototypeifektri.I-Huihe Circuits yamukela izinto ze-A-grade, ubuchwepheshe bokukhiqiza ibhodi le-PCB le-masters elingenalutho, futhi ifakwe imishini yokukhiqiza ezenzakalelayo ethembekile, imishini yokuhlola kanye namalabhorethri angokwenyama namakhemikhali asebenza ngokugcwele, kungakhathaliseki ukuthi wenza imishini yokuxhumana, ugesi wezimoto, ukulawula izimboni, noma ukwelashwa. ukwelashwa.& nokuvikeleka kanye neminye imikhiqizo yobuchwepheshe obuphezulu, noma udinga ezinye izinsiza zebhodi le-PCB elingenalutho, Izifunda ze-Huihe zikuhlinzeka ngezinkonzo zobungcweti ezibanzi nezisezingeni eliphezulu.
