Mafaira einjiniya anoshandiswa mukugadzira PCB anosanganisira maPCB mafaera, ODB++ mafaera, maGerber mafaera, uye EXCELLON mafaera. Pakati peizvi, mafaira eGerber anoshandiswa kufotoplotting kugadzira firimu rekuratidzwa uye kudhinda skrini. EXCELLON mafomati mafaera anoshanda sekuchera uye kugaya chirongwa mafaera, kufambisa gomba kuchera uye kuumbwa. Mafaira ePCB anofanirwa kushandurwa kuita Gerber uye EXCELLON mafomati kuti ashandiswe mukugadzira. Kune rimwe divi, CAM software yekugadzira PCB inogona kuverenga zvakananga ODB ++ faira data.
PCB Data Files
Chii chinonzi PCB File?
Mafaira ePCB ndiwo mafaira ekugadzira akachengetwa kubva kuEDA (Electronic Design Automation) software. Aya mafaera haakwanise kushanda zvakananga semafaira ekushandisa ekugadzira sezvo michina yekugadzira isingakwanise kuziva PCB faira mafomati. Yese PCB data mafaera akachengetwa kubva kuEDA software inoda kushandurwa kuita Gerber fomati yekugadzira. Gerber mafaera ndiyo yekutanga faira fomati inoshandiswa mukugadzira michina, kunyangwe mamwe maturusi ekuongorora anogona kutsigira ODB ++ fomati.

Munguva yekugadzira PCB, mafaira eGerber akakosha mukati mekuita, kubva pakuona online uye kudhinda PCB kusvika pakugadzira zvinhu zvekugadzira uye AOI (Automated Optical Inspection). Mafaira eGerber anoita senge rengedzo rekutungamira kune isina musono PCB kugadzirwa.
Pamusangano wePCB, ma template layers mukati meGerber mafaira anopa hwaro hwekugadzirisa zvinzvimbo zvezvakasiyana siyana zvemagetsi, zvinotungamira zvese SMT (Surface Mount Technology) uye kuburikidza-gomba magungano maitiro.
ODB++ Data Files
Chii chinonzi ODB++?
ODB++ iASCII-based bidirectional data transmission format yakakurudzirwa naMentor, nhengo yeIPC. Iyi faira fomati inobatanidza ese PCB uye gungano rinoshanda tsananguro, inosanganisira dhizaini, kugadzira, uye gungano zvinodiwa. Inosanganisira PCB kudhirowa, routing layer, wiring diagraphs, pad stacks, zvigadziriso, nezvimwe.
ODB ++ yakaunzwa kuti igadzirise zvisingakwanisi zvemafaira eGerber nekubatanidza ruzivo rwakakwana rwekugadzira uye gungano.
Zvakanakira zveODB++
Iyo ODB ++ fomati yakagadzirirwa kuvhara musiyano pakati pemafaira ekugadzira uye zvigadzirwa zvakapedzwa. Vagadziri vePCB pakutanga vakagamuchira iyi fomati, vachibvisa kukosha kwekuunganidza akawanda CAM faira mafomati seGerber, Excellon, IPC-356, uye IPC-350. Kubudirira kweODB++ kuri mukugamuchirwa kwayo kweindasitiri uye kugona kwayo kurerutsa shanduko yedata.
Gerber / Excellon Data Files
Chii chinonzi Gerber File?
Gerber, inonziwo "photoplot," inomiririra mafomati akadai seRS-274, 274D, uye 274X. Aya anoshanda sevamiriri vekushandura dhizaini graphic data muPCB kugadzira. Mafaira eGerber anonyanya kushandiswa kuPCB marongero ekuronga, pakupedzisira achigonesa vagadziri vePCB kuburitsa maPCB. Iyo inonyanya kushandiswa Gerber fomati muindasitiri yekugadzira ndeye GERBER 274X.
Kushandiswa kweGerber Files
Mafaira eGerber akakosha mumatanho ese ekugadzira PCB, achishanda senzira yakavimbika yekuendesa data redhizaini kumidziyo yekugadzira.
Chii chinonzi Excellon File?
EXCELLON imhando yekupayona yekuchera-inodzorwa nekombuta nemichina yekugaya. Yakagadzira hurongwa hwemutauro wekuraira unonzi Excellon Computer Numeric Control (CNC), iyo yakava chiyero cheindasitiri. Pakutanga, yakaunza mitauro yakasiyana yekuchera (Format One) nekugaya (Format Two).
Muna 1979, Excellon yakagadziridza iyo Format Two mutauro, kubatanidza yekuchera uye yekugaya mirairo kuita imwechete system. Michina yakagadzirwa gore ra1979 risati rasvika, yaizivikanwa seGeneration One, yaingokwanisa kushandisa Format One, asi iya yakazotevera 1979, yakanyorwa kuti Generation Two, yaitsigira zvose Format One uye Format Two.
