Haugone kuona mukati memabhodhi ecircuit akadhindwa ane layer yakawanda nemaziso ako. X-ray 3D imaging inoratidza zviratidzo zvakavanzika uye ma vias anoramba asingaonekwe nemakamera nema microscopes. Traditional reverse engineering inoda kupatsanurwa kwe layer inoparadza. Unonyungudutsa layer nemakemikari, wobvisa bhodhi rekutanga zvachose. Kubvisa layer nemaoko kunotora nguva yakareba (mavhiki) uye kunokusiya usina chekusimbisa basa rako.
Kuongororwa kwe3D Imaging X-ray tomography kunopa ongororo isingaparadze yezvivakwa zvese zvemukati zvePrinted Circuit Board. Tekinoroji iyi yakafambira mberi kubva pakuongorora kuri nyore kwe2D X-ray mukutanga kwema2000 kusvika kumasisitimu e3D CT scanning anowanikwa muna 2026. Unochengetedza bhodhi rekutanga risina kukuvadzwa zvachose. Unoona zvidimbu zvese panguva imwe chete ne micron-level resolution. Kuongorora kwakatora mavhiki ikozvino kunopera mumaawa nekunyatsorongeka kuri nani.
Gwaro iri rinotsanangura mashandiro anoita X-ray imaging pakuongorora mabhodhi edunhu akadhindwa. Uchadzidza zvakakosha zvetekinoroji, kunzwisisa maitiro e3D imaging, kuziva nguva yekushandisa X-ray kana nzira dzemazuva ese, kuongorora michina kana sarudzo dzebasa, uye kuverenga mitengo yemapurojekiti ako emagetsi.
Chii chinonzi X-Ray PCB Imaging?
Kunzwisisa Tekinoroji yeX-Ray yePCBs
Kufungidzira kwe3D, maX-ray anopinda mumidziyo yebhodhi redunhu rakadhindwa nemazinga akasiyana zvichienderana nehuwandu. Substrate yeFR-4 inobvumira maX-ray kuti apfuure zviri nyore nekuti ine huwandu hushoma. Zvidimbu zvemhangura zvinovhara maX-ray akawanda nekuti mhangura isimbi yakakora. Solder isina lead inovhara maX-ray akawanda kupfuura mhangura. Kunyudzwa uku kwakasiyana kunogadzira musiyano mumifananidzo yeX-ray. Zvinhu zvakakora zvinotaridzika zvakasviba mumifananidzo yeX-ray nekuti zvinovhara mwaranzi yakawanda. Zvidimbu zvemhangura zvinoonekwa zvakasviba zvichipesana neFR-4 background yakareruka. Majoini esolder anoita seakasviba zvikuru. Zvinhu zvisina kukora zvakanyanya seFR-4 substrate uye mhepo inobuda zvinoita seyakareruka kana kuti yakajeka. Mugumisiro ndewekuti unoona zvidimbu zvemhangura zvemukati, kuburikidza nekubatanidza, uye majoini esolder ezvikamu pasina kuvhura bhodhi redunhu.

Mibvunzo Inonyanya Kubvunzwa
Kufungidzira kweX-ray kunogona kukanganisa PCB yangu kana zvikamu zvayo here?
Kwete, X-ray imaging haiparadzi zvachose. Dose yeX-ray inoshandiswa pakuongorora PCB yakaderera zvikuru uye haikanganisi bhodhi, zvikamu, kana mashandiro aro. Mushure mekuskena, PCB yako inoshanda sezvayaimboita.
Kuverengeka kwezvikamu kunoda X-ray vs Optical Review?
Kumabhodhi ane zvidimbu zviviri kusvika zvina, kuongororwa kwemaziso kunowanzo kukwana. Kumabhodhi ane zvidimbu zvitanhatu zvichikwira, X-ray imaging inokurudzirwa zvikuru kuti uone zvidimbu zvemukati. Kumabhodhi ane zvidimbu zvisere zvichikwira, X-ray inonyanya kukosha kuti pave nereverse engineering chaiyo.
Kuongororwa kweX-ray ye3D kunotora nguva yakareba sei?
Kuskena kunotora maminetsi makumi matatu kusvika kumaawa matatu zvichienderana nehukuru hwebhodhi uye resolution. Kugadziriswa kwe3D kunowedzera maminetsi gumi nemashanu kusvika kumaawa maviri. Maitiro ese kubva pabhodhi rekurodha kusvika pakuongorora kwekupedzisira anotora maawa mana kusvika masere. Mhedzisiro yakazara nekuongorora kwenyanzvi inounzwa mumazuva matatu kusvika manomwe.
Ndeapi mafaira aunopa mushure mekuongorora X-ray?
Tinopa data re3D volumetric raw muDICOM format, mifananidzo ye2D layer-by-layer seTIFF kana PNG files, mafaira e3D visualization muSTL format yekuona, ma trace maps akatorwa, uye ma final schematics muCAD format yaunoda kusanganisira Eagle, Altium, neKiCad.
Kutora mifananidzo yeX-ray kwakakodzera here pabasa rangu?
Kune mapuranga ane zvidimbu zvitanhatu kana kupfuura, hongu. Kudhirowa kwePCB yeX-ray kunodhura $1,000-$2,000 asi kunochengetedza mavhiki ekunonoka nemaoko kunodhura $3,000-$8,000 pakusununguka. Unochengetedzawo bhodhi rako rekutanga kuti riongororwe uye risimbiswe. Kune mapuranga akareruka ane zvidimbu zviviri kusvika zvina, nzira dzekutarisa dzinowanzo kukwana uye dzinoshanda zvishoma.
