Indlela Yokukhiqiza Amafayela e-Gerber Okukhiqiza i-PCB

Amafayela e-Gerber ayidatha yesendlalelo ngesendlalelo esetshenziswa yi-fab ukwakha ibhodi lakho, futhi ukuwakhiqiza ngendlela efanele yisinyathelo esiphakathi komklamo oqediwe kanye ne-oda elenziwayo. Inqubo iyafana kuwo wonke amathuluzi e-EDA - khiqiza i-Gerber ngesendlalelo kanye nefayela lokubhoboza le-NC, bese uwaqinisekisa - kodwa imininingwane kanye nokuzenzakalelayo kuyahluka, futhi amaphutha amancane lapha abangela ukubambezeleka kwangempela. Lo mhlahlandlela uchaza indlela yokukhiqiza isethi ephelele, efanele ye-Gerber, okufanele ukuhlole ngaphambi kokuyithumela, nokuthi i-Highleap Electronics ibuyekeza kanjani idatha yakho ngaphambi kokwakha.

1. Yimaphi amafayela akha iphakheji ephelele ye-Gerber?

Iphakheji ephelele ye-Gerber iyifayela elilodwa le-Gerber ngesendlalelo ngasinye — ithusi ngalinye, imaski yokubopha, kanye nesendlalelo sesikrini se-silkscreen, kanye nohlaka lwebhodi kanye nezendlalelo zokunamathisela — kanye nefayela lokubhoboza le-NC elichaza yonke imbobo. Ngaphandle kwesethi ephelele, ifenisha ayikwazi ukwakha ibhodi lakho, futhi isendlalelo esingekho (ngokuvamile ifayela le-solder-mask noma lokunamathisela) ingenye yezizathu ezivame kakhulu zokuthi ama-quote stalls abekwe.

Kwibhodi elizohlanganiswa futhi, ifayela le-Gerbers kanye ne-drill lihlanganiswa yidatha ye-assembly: ibhili yezinto ezinezinombolo zezingxenye zomkhiqizi, ifayela lokukhetha nokubeka (centroid), kanye nomdwebo we-assembly. Ama-fabs amaningi manje ayamukela ne -ODB++ , isethi yedatha eyodwa ehlakaniphile ehlanganisa lonke ulwazi lwesendlalelo kanye ne-drill futhi isuse okuningi kokungaqondakali kokuqamba izingqimba okungalethwa yi-Gerbers ecacile. Isithombe esiphelele salokho umkhiqizi akudingayo simbozwe kulokhu kubuka konke kwamafayela okuklama e-PCB.

2. Indlela yokukhiqiza amafayela e-Gerber ku-Altium, KiCad, kanye ne-EAGLE

Ukuze ukhiqize ama-Gerber, sebenzisa umsebenzi wokukhiqiza-wokukhipha wethuluzi lakho le-EDA — Imikhiqizo Yokukhiqiza ku-Altium, I-Plot ku-KiCad, noma i-CAM Processor ku-EAGLE — khetha izendlalelo ozozithumela, bese ukhiqiza ifayela le-NC drill ngokwehlukana. Ukugeleza kuyafana emoyeni kuwo wonke amathuluzi; amagama emenyu kanye nokuzenzakalelayo kuyahluka:

• Umklami we-Altium. Vula i-PCB, bese uFayela → Imiphumela Yokukhiqiza → Amafayela e-Gerber; khetha amayunithi nokunemba, khetha izendlalelo, bese ukhiqiza i-NC drill ngokwehlukana.
• I-KiCad. Kumhleli we-PCB, iFayela → Hlela ukuze ukhiphe ama-Gerber ezingqimbeni ezikhethiwe, bese uthi “Khiqiza Amafayela Okudonsa.” I-KiCad ifaka nesibukeli esakhelwe ngaphakathi (i-GerbView) ukuhlola umphumela.
• UKHOZI. Sebenzisa i-CAM Processor enomsebenzi ojwayelekile we-RS-274X CAM; qaphela ukuthi ngokuzenzakalelayo kuphela ukuthunyelwa kwe-silkscreen ephezulu, ngakho-ke engeza i-silkscreen engezansi uma ibhodi lakho liyidinga.

Noma yiliphi ithuluzi olisebenzisayo, isimiso siyafana: thumela yonke ingqimba edingekayo kanye nefayela lokubhoboza, ngefomethi yesimanje, enezilungiselelo ezihambisanayo. Amafayela ajwayelekile afanayo yiwo avumela noma yimuphi umuntu onekhono ukwakha ibhodi kungakhathaliseki ukuthi ithuluzi lokuklama liyini - futhi indima ebanzi yonjiniyela we-CAM odla idatha yakho ifanele ukuqondwa, ngoba umsebenzi wabo ukuguqula lawa mafayela abe yisakhiwo.

3. Izilungiselelo zokuthumela ngaphandle ze-Gerber ezivimbela amaphutha okukhiqiza

Izilungiselelo zokuthumela ezivimbela amaphutha yilezi: sebenzisa ifomethi ye-RS-274X (noma i-X2), setha amayunithi ahambisanayo kanye nokunemba okwanele kwedesimali, faka zonke izendlalelo ezidingekayo, futhi ugcine ifayela lokubhoboza liqondaniswe nomsuka ofanayo namaGerber. Izinkinga eziningi "zebhodi elingalungile" zibuyela emuva kwesinye salezi zilungiselelo kunokwakheka ngokwako. Thola lokhu kahle:

• Fometha. Sebenzisa i-RS-274X yesimanje (noma i-X2 entsha), efaka idatha ye-aperture, esikhundleni samafomethi aphelelwe yisikhathi adinga amafayela e-aperture ahlukene.
• Amayunithi nokunemba. Khetha i-intshi noma i-millimeter ngokuqhubekayo kuwo wonke amafayela, ngokunemba okwanele kwedesimali ukuze uthole izici zakho ezinhle kakhulu — ukungafani kwamayunithi kungakhulisa ibhodi lonke.
• Isethi ephelele yezendlalelo. Thumela yonke ithusi, imaski, isikrini sesilika, unamathisele, kanye nesendlalelo sohlaka; qinisekisa ukuthi akukho okuvaliwe ngokuzenzakalelayo.
• Ukulungiswa kwe-drill. Khiqiza i-NC drill evela endaweni efanayo ukuze imigodi ihambisane nethusi.

Ngithanda i-ODB++ lapho i-fab yakho iyisekela khona, ngoba ukuhlanganisa idatha kusethi yedatha eyodwa kugwema lonke uhlobo lwamaphutha okuqamba izingqimba kanye nokuqondanisa okumema amafayela e-Gerber alahlekile.

4. Indlela yokuhlola amafayela akho e-Gerber ngaphambi kokuwathumela

Vula njalo ama-Gerber akho akhiqizwe kumbukeli ozimele ngaphambi kokuwathumela, bese uqinisekisa ukuthi zonke izendlalelo zikhona, akukho lutho oluboniswayo, i-drill ihambisana nama-pads, futhi uhlaka lwebhodi lulungile. Ukubuka kuqala kwangaphakathi kwethuluzi lakho le-EDA akufani nalokho okutholwa yifektri, ngakho-ke ukuhlolwa kwangaphandle okusheshayo kungumshuwalense oshibhile kakhulu kulo lonke uhambo. Qinisekisa:

• Zonke izendlalelo zikhona — ungqimba ngalunye lwethusi, imaski, kanye nesendlalelo sesikrini sesilika zithunyelwa ngaphandle njengoba bekulindelekile.
• Azikho izendlalelo ezibukwayo — isikrini se-silkscreen esiphezulu sifundeka kahle kusukela phezulu.
• Ukulungiswa kwe-drill — imigodi ifika kuma-pad azo ngobukhulu obufanele.
• Uhlaka olufanele kanye nesilinganiso — ibhodi liyisayizi efanele kanye nama-cutout lapho kuhloswe khona.

Ukubamba ungqimba olubukisiwe noma imaski engekho lapha kuguqula inqwaba elahliwe ibe yisisombululo semizuzu emibili. Imininingwane yokuthi kungani lokhu kubalulekile, kanye nokubheka ngokujulile ifomethi ngokwayo, ikumhlahlandlela ophelele wamafayela e-Gerber.

5. Amaphutha efayela le-Gerber ajwayelekile nokuthi ungawalungisa kanjani

Amaphutha avame kakhulu e-Gerber ungqimba olungekho, ungqimba olubukisiwe, ukungalingani kwamayunithi noma isikali, ifayela lokubhoboza elingalingani kahle, kanye nezimbobo ezingekho ezivela kufomethi ephelelwe yisikhathi - futhi cishe zonke ziyiphutha lokusetha ukuthumela ngaphandle, hhayi amaphutha okuklama. Ngoba azibonakali ngaphakathi kwethuluzi lakho le-CAD futhi zivela kuphela kumbukeli noma ngendlela efanele, ukwazi ukulungisa ngakunye kusindisa impendulo:

Umkhuba owodwa ovimbela cishe konke lokhu ukuvula isethi ethunyelwe kumbukeli ozimele bese uqinisekisa izendlalelo, ukwenza isibuko, ukuqondisa ukubhoboza, kanye nohlaka ngaphambi kokuthumela. Ukushintshela ku- ODB++ kususa ngokuphelele izigaba ze-aperture ezingekho kanye ne-layer-naming, njengoba idatha ihlanganiswe kusethi yedatha eyodwa ehlakaniphile. Izinkinga ezisele - kanye neziningi amaGerber angenakuzibonisa, njengesikhala esingaphansi - zibanjwa ukuhlolwa kwe-DFM komklami ngaphambi kokuba ibhodi lakhiwe.

6. Indlela i-Highleap ebuyekeza ngayo ama-Gerber akho ngaphambi kokwakha

I-Highleap ivula futhi ihlole idatha yakho ye-Gerber kanye ne-drill ngaphambi kokwakha - iqinisekisa ukuthi zonke izendlalelo zikhona, akukho lutho oluboniswayo, ama-drill ayahambisana, futhi umklamo uyakhiqizwa - bese imaka noma yini engabangela ukuvinjelwa. Lokhu kuyinethi yesibili yokuphepha ngaphezu kokuhlola kwakho kwababukeli, futhi ngemiklamo eyimfihlo kuyisibuyekezo sangaphakathi esiyimfihlo kunokuba kube ukulayisha komphakathi.

Ukusuka lapho amafayela afanayo aqinisekisiwe aqhuba ukwenziwa kanye, lapho kudingeka khona, ukuhlanganiswa, ngakho womabili asebenza kusukela ekubuyekezweni okukodwa. Ukubuyekezwa kokwenziwa kwangaphambi kokwakhiwa kubamba izinkinga amaGerbers ewodwa angazivezi, njengesikhala esingaphansi noma indawo engeke ihlangane kahle. Thumela isethi yeGerber ehlanzekile, ehlolwe ngababukeli (noma i-ODB++) enefayela lokubhoboza, uhlaka lwebhodi, i-stackup, kanye nobuningi, bese isilinganiso nokwakhiwa kuqhubeka ngaphandle kokubuyela emuva naphambili nge- turnkey assembly.

7. Imibuzo Evame Ukubuzwa Ngokukhiqiza Amafayela e-Gerber

Ngiwavula futhi ngiwabuke kanjani amafayela e-Gerber?

Layisha isethi ephelele kusibukeli se-Gerber — amathuluzi amaningi e-EDA afaka elilodwa (i-KiCad ine-GerbView), kanye nababukeli abazimele nabaku-inthanethi abakhona. Nqampuna zonke izendlalelo kanye nefayela lokubhoboza ekubhaliseni, bese ushintsha izendlalelo bese ushintsha ukubuka okuphezulu/phansi ukuze uhlole.

Kusho ukuthini i-RS-274X, futhi ihluke kanjani ku-RS-274D?

I-RS-274X iyifomethi yesimanje "enwetshiwe" ye-Gerber efaka izincazelo ze-aperture ngaphakathi kwefayela ngalinye. I-RS-274D endala yayidinga uhlu lwe-aperture oluhlukile, olwaluwumthombo ovame ukuba namaphutha, ngakho-ke i-RS-274D ayisasebenzi futhi akufanele isetshenziswe.

Ingabe kufanele ngiziphe amafayela ami e-Gerber ngaphambi kokuwathumela?

Yebo — paka isethi ephelele yesendlalelo kanye nefayela lokubhoboza ndawonye kungobo yomlando eyodwa ecindezelwe ukuze kungabikho lutho olulahlekile noma oluhlukaniswe ngesikhathi sokuthutha. Gcina amagama amafayela ajwayelekile ethuluzi lakho, bese ufaka imephu yesendlalelo emfushane uma kukhona amagama angacacile.

Ingabe ifayela lokubhoboza liyingxenye yamaGerber noma lihlukile?
