I-Gerber vs ODB++ vs IPC-2581: Ukukhetha Iphakheji Yedatha Yokukhiqiza ye-PCB

Ukukhetha phakathi kwe-Gerber, i-ODB++, kanye ne-IPC-2581 kuyisinqumo mayelana nokuthi ufuna ukunikeza ubuhlakani obungakanani bokukhiqiza umsebenzi. I-Gerber cishe iyinto yonke kodwa isekelwe ezingqimbeni, kuyilapho i-ODB++ kanye ne-IPC-2581 zifaka umongo wokuklama okwengeziwe kusethi yedatha ehlanzekile yokukhiqiza nokuhlanganisa. Lo mhlahlandlela uqhathanisa amafomethi amathathu okukhiqiza angathathi hlangothi, uchaza ukuthi ngayinye ikhetha nini kangcono, futhi ukhombisa ukuthi i-Highleap Electronics isebenzisa kanjani lonke iphakheji yedatha ukwakha nokuhlanganisa ibhodi.

1. Yimaphi amafomethi amafayela adingwa umenzi we-PCB?

Umenzi we-PCB udinga isethi yedatha yokwenziwa — kungaba amafayela e-Gerber kanye nefayela lokubhoboza le-NC, noma ifomethi ye-all-in-one efana ne-ODB++ noma i-IPC-2581 — kanye, ukuze ahlanganiswe, ibhili yezinto zokwakha, ifayela lokukhetha nokubeka (centroid), kanye nomdwebo wokuhlanganiswa. Idatha yokwenziwa ichaza ibhodi elingenalutho; idatha yokuhlanganiswa ichaza ukuthi kwenzekani kulo nokuthi kuphi.

Lawa mafomethi akhona ngoba ifayela lakho lephrojekthi ye-CAD liqondene namathuluzi futhi alikwazi ukwakheka ngqo, kanti lawa ayimiphumela engathathi hlangothi, ejwayelekile noma yimuphi umuntu angayifunda. Isethi ephelele umenzi ayilindele ifingqiwe kulokhu kubuka konke kwamafayela okuklama e-PCB , kanye nezinyathelo ezisebenzayo "zendlela yokuwakhiqiza" zitholakala kumhlahlandlela ohambisanayo kumafayela e-Gerber . Okunye kwalesi sihloko kuchaza ukuthi ifomethi ngayinye iqukethe ini ngempela ukuze ukwazi ukuthumela iphakheji efanele okokuqala.

2. Iyini ifayela le-Gerber futhi liquketheni?

Ifayela le-Gerber liyifayela le-vector le-2D elichaza ungqimba olulodwa lwe-PCB — imaski yalo yethusi, i-solder, noma isikrini sesilika — njengeqoqo lezimo ezidwetshwe ngemibhobho echaziwe. I-Gerber eyodwa imele ungqimba olulodwa, ngakho-ke iphakheji ephelele yebhodi elingenalutho iyifolda yama-Gerber (ithusi eliphezulu nelingezansi, izendlalelo zangaphakathi, zombili izimaski ze-solder, zombili izikrini zesilika, izendlalelo zokunamathisela, kanye nohlaka lwebhodi) oluhambisana nefayela elihlukile le-NC lokubhoboza lemigodi.

Izinga lesimanje yi-RS-274X (kanye ne-X2 entsha), efaka izincazelo ze-aperture ngaphakathi kwefayela — ama-Gerber amadala e-“RS-274D” ayedinga uhlu lwe-aperture oluhlukile futhi awasebenzi futhi avame ukuba namaphutha. Ngenxa yokuthi ungqimba ngalunye luyifayela elihlukile elinegama olinikezayo, ubuthakathaka obukhulu bama-Gerber alula ukungacaci: ungqimba olunelebula elingalungile noma olungekho luyimbangela evamile yokubamba ukukhiqiza, yingakho isethi ngayinye ye-Gerber kufanele ihlolwe kumbukeli ngaphambi kokuthumela nokuthi kungani amafomethi aphelele-ku-one angezansi adalwe. Idatha ye-Gerber iphinde ifake ngqo esinyathelweni se -CAM lapho i-fab iguqula amafayela akho abe yisakhiwo.

3. I-Gerber vs ODB++ vs IPC-2581: iyiphi ifomethi engcono kakhulu?

I-Gerber iyisisekelo esijwayelekile, kuyilapho i-ODB++ kanye ne-IPC-2581 kuyifomethi yefayela elilodwa ehlakaniphile ehlanganisa yonke idatha yesendlalelo, i-drill, i-netlist, kanye nedatha ye-BOM ndawonye - okwenza kube lula ukwenza amaphutha futhi kube nokukhetha okungcono lapho i-fab yakho izisekela khona. Ukushintshana kungokuhlukahlukana uma kuqhathaniswa nokuceba:

Kumaphrojekthi amaningi, i-Gerber isebenza yonke indawo futhi ihlala iyinto ephephile ezenzakalelayo. Lapho umenzi wakho ekwamukela khona, i-ODB++ ingcono ngoba ukupakisha zonke izingqimba, idatha yokubhoboza, kanye ne-netlist kusethi eyodwa yedatha ehlakaniphile kususa ukungaqondakali kokuqanjwa kwezingqimba kanye nokuqondanisa okumenywa amafolda e-Gerber akhululekile. I-IPC-2581 iphishekela umgomo ofanayo nendinganiso eyodwa evulekile, engakhethi hlangothi yomthengisi. Ifomethi engcono kakhulu imane iyona ecebile kakhulu oyisekelayo - futhi ukuqinisekisa ukuthi kusengaphambili kugwema ukuphinda usebenze.

4. Ukubhoboza, i-BOM, bese ukhetha amafayela ukuze ahlanganiswe

Kwibhodi elihlanganisiwe kufanele futhi unikeze amafayela amathathu: ifayela lokubhoboza le-NC (indawo yembobo ngayinye, usayizi, nesimo seplati), uhlu lwezinto zokwakha (ingxenye ngayinye enenombolo yengxenye yomkhiqizi wayo), kanye nefayela lokukhetha nokubeka (indawo yengxenye ngayinye, ukujikeleza, kanye nohlangothi). Imininingwane yokwenziwa yodwa yenza ibhodi elingenalutho; lokhu kuyiguqula ibe yi-PCBA egcwele abantu. Lokho okunikezwa yiyo ngayinye:

• Ifayela le-NC drill. Ichaza ukubhoboza — ubukhulu bemigodi, izixhumanisi, kanye nesimo sokubhoboza uma kuqhathaniswa nesimo sokungabhoboza — futhi iyingxenye yesethi yokwenziwa yize ihlukile kumaGerber.
• Uhlu lwezinto zokwakha. Ibala yonke ingxenye ngenombolo yangempela yengxenye yomkhiqizi, hhayi nje inani, ukuze izingxenye zitholakale ngempela; okuphelele Idatha ye-PCB BOM kubalulekile ekuthengeni nasekuthengeni okunembile.
• Ifayela lokukhetha nokubeka (eliphakathi nendawo). Inikeza indawo ye-X/Y yengxenye ngayinye, ukujikeleza, kanye nohlangothi lwebhodi ukuze umshini wokubeka uyibeke kahle; nansi indlela ukuhlanganiswa kwamadrayivu efayela le-centroid.
• Umdwebo wokuhlanganisa. Ibonisa i-polarity, i-pin eyodwa, ama-fiducial, kanye namanothi okungamelwe agcwaliswe amafayela edatha wodwa angawavezi.

Iphakheji yokuhlanganisa engaphelele — ama-Gerber angenazo izinombolo zezingxenye ze-BOM, noma ifayela le-centroid elingekho — ingenye yezizathu ezivame kakhulu zokuthi isilinganiso somhlangano singakwazi ukuqedwa, ngakho ukuthumela konke lokhu ndawonye kugcina iphrojekthi iqhubeka.

5. Iyini ifayela ngalinye lesendlalelo se-Gerber nokuthi ungaliqamba kanjani

Kuphakheji ye-Gerber, ifayela ngalinye limelela ungqimba olulodwa olubonakalayo lwebhodi, futhi ukuqanjwa okucacile yikho okuvimba umenzi wezinto ukuthi aqagele ukuthi yiliphi ifayela eliyiphi. Ngenxa yokuthi ama-Gerber alula awaphethe ilebula eliyi-"thina yithusi ephezulu" elingaphezu kwegama lefayela, uhlelo lokuqamba olungacacile noma olungejwayelekile luyimbangela evamile yokubamba kokukhiqiza. Iphakheji ephelele enezingqimba ezimbili, kanye nezendlalelo ibhodi enezingqimba eziningi ezingezayo, zibukeka kanje:

Izandiso ziyahlukahluka phakathi kwamathuluzi e-EDA, ngakho-ke umkhuba ophephile ukugcina ukuqanjwa okujwayelekile kwethuluzi lakho, faka imephu yokufunda emfushane noma yeleya lapho amagama engabonakali, bese usho ukuhleleka kweleya kwamabhodi amaningi ukuze izendlalelo zangaphakathi zibekwe kahle. Lokhu kungaqondakali kwamagama yinkinga esuswa yi -ODB++ ngokuhlanganisa zonke izendlalelo, indima yazo, kanye nedatha yokubhoboza kusethi yedatha eyodwa ehlelekile - yingakho kuyisiphatho esithandwayo lapho i-fab iyisekela khona. Noma yini oyithumelayo, ukuvula iphakheji kusibukeli kuqinisekisa ukuthi izendlalelo ziphelele futhi zihlonzwe kahle ngaphambi kokuba zifike esinyathelweni se-CAM.

6. Indlela i-Highleap esebenzisa ngayo amafayela akho ukwakha ibhodi

I-Highleap yamukela idatha yokwenziwa kwe-Gerber, i-ODB++, noma i-IPC-2581 kanye nomdwebo wakho we-BOM, ukukhetha nokubeka, kanye nokuhlanganisa, bese iqinisekisa iphakheji ngaphambi kokwakha ngakho umsebenzi wokwenziwa nokuhlanganisa uvela ekubuyekezweni okukodwa okuqinisekisiwe. Noma ngabe iyiphi ifomethi oyithumelayo, amafayela ayavulwa futhi ahlolwe — izendlalelo zikhona, akukho okubonisiwe, ukuqondisana kokubhoboza, i-BOM kanye ne-centroid kuyahambisana — futhi noma yini engabangela ukubamba imakwe kusenesikhathi.

Lokhu kubuyekezwa kuyisinyathelo sangasese, sangaphakathi (hhayi ukulayishwa komphakathi), futhi kuhambisana nokubuyekezwa kokwenziwa okubamba izinkinga amafayela wodwa angazivezi. Ukusuka lapho idatha eqinisekisiwe iqhuba ukwenziwa kanye nokuhlanganiswa kwe-turnkey ngokuthola, ukubeka, ukuhlola, kanye nokuhlola. Ukuze uthole isilinganiso esinembile okokuqala, thumela idatha yakho yokwenziwa (i-Gerber noma i-ODB++, ifayela le-NC drill, i-BOM enezinombolo zezingxenye, ifayela lokukhetha nokubeka, uhlaka lwebhodi, i-stackup, kanye nobuningi.

7. Imibuzo Evame Ukubuzwa Ngefomethi Yefayela Le-PCB

Yisiphi isofthiwe esivula amafayela e-Gerber?

Izibukeli ze-Gerber ezizinikele, isibukeli esakhelwe ngaphakathi sethuluzi lakho le-EDA (i-KiCad ifaka i-GerbView), kanye nezibukeli ezahlukene zamahhala zedeskithophu kanye ne-inthanethi zonke zivula i-Gerbers. Layisha isethi ephelele yesendlalelo kanye nefayela lokubhoboza ndawonye ukuze ubone ibhodi njengoba umenzi ezokwenza.

Uyini umehluko phakathi kwefayela le-Gerber nefayela le-Excellon drill?
