Taw qhia rau kev suav ntawm microscope magnification
Ntau lub chaw soj nstuam tau siv lub tshuab ntsuas tshuab, tab sis cov kws tshaj lij ntawm lub tshuab ntsuas ntsuas tsis nkag siab, tsuas yog paub yuav ua li cas khiav lag luam, tab sis rau qee qhov kev txiav txim siab yooj yim yuav tsis meej meej, yog li hnub no peb yuav tham txog lub tshuab ntsuas qhov ntsuas qhov ntsuas li cas?
Tej zaum ib tug yuav hais tias qhov no tsis yog ib lo lus nug yooj yim heev, tab sis qhov tseeb los yog me ntsis nyuaj.
Ua ntej tshaj plaws, cia peb ua piv txwv: thaum lub qhov muag ntawm lub tso suab tso suab yog 10 lub sij hawm qhov magnification, qhov zoom ntau yog: 0.7X-4.5X, lub hom phiaj ntxiv lens yog: 2X, qhov optical magnification yog: 10 npaug ntawm 0.7 npaug 2 kom tau qhov qis tshaj magnification ntawm lub tshuab ntsuas no yog: 14 npaug, qhov siab tshaj plaws multiplier yog: 10 zaug 4.5 npaug 2 sib npaug rau 90 npaug, tag nrho cov optical magnification ntawm stereo microscope yog 14 zaug rau 90 zaug. Tag nrho cov optical magnification ntawm lub tshuab ntsuas no yog los ntawm 14 npaug rau 90 zaug. Ntawm chav kawm, qhov no tsuas yog qhov tseeb magnification ntawm lub microscope party. Tom ntej no yog qhov kev nthuav dav digital ntawm lub tshuab microscope.
Piv txwv li, qhov loj ntawm lub monitor yog 17 ntiv tes, nrog 1/3 ntawm lub koob yees duab microscope, qhov kev nthuav dav digital ntawm lub koob yees duab microscope tawm tsam cov lus hauv qab no yog: 72 zaug. Lub tshuab microscope digital magnification ib qho kev suav cov mis yog: qhov kev teeb tsa ntawm lub cev saum toj no saib lub tshuab tsom, lub varioid yog varioid yog 0.7X-4.5X, lub hom phiaj ntxiv yog 2X. lub koob yees duab eyepiece rau 1 (xws li lub koob yees duab eyepiece tsis tas yuav koom nrog kev suav ntawm tus lej). Raws li cov qauv: lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification, digital magnification ntawm qhov tsawg kawg nkaus tus lej yog: 0.7 zaug 2 zaug 1 zaug 72 yog sib npaug rau: 100.8 npaug, digital magnification ntawm qhov siab tshaj plaws yog : 4,5 x 2 x 1 x 72=648 x . Qhov ntau ntawm digital magnification yog 100.8 npaug rau 648 zaug.
Hauv qhov no, yuav muaj ob txoj hauv kev:
1, tag nrho optical magnification=eyepiece magnification X lub hom phiaj lens magnification
2, digital tag nrho magnification=lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification
Cov mis no tsim nyog rau txhua lub tshuab tsom, txawm tias nws yog lub tshuab kuaj kab mob metallurgical, lub tshuab kuaj kab mob lom neeg thiab lwm yam.
Beijing Chip Failure Analysis Laboratory
IC Failure Analysis Laboratory
Ua tiav thiab ua haujlwm thaum kawg ntawm xyoo 2015, Northsoft Testing Intelligent Product Testing Laboratory muaj peev xwm siv cov kev sim ua haujlwm raws li cov qauv thoob ntiaj teb, hauv tsev thiab kev lag luam, ua tiav kev sim ua haujlwm los ntawm lub hauv paus nti mus rau cov khoom siv tiag tiag, thiab los ntawm lub cev mus rau qhov laj thawj, thiab muab nti preprocessing, sab-channel nres, kho qhov muag nres, intrusive nres, ib puag ncig, voltage burr nres, electromagnetic txhaj, hluav taws xob txhaj tshuaj, lub cev kev ruaj ntseg, logical kev ruaj ntseg, functionality, compatibility, thiab multi-point laser txhaj. compatibility thiab multi-point laser txhaj tshuaj, thiab lwm yam Meanwhile, peb muaj peev xwm nqa tawm simulation rau reproduce lub phenomenon ntawm tsis ua hauj lwm ntawm cov khoom ntse thiab nrhiav kom paub qhov ua rau tsis ua hauj lwm tsom xam thiab kuaj cov kev pab cuam, uas feem ntau muaj xws li point-and-shoot workstations (ProbeStation) , Reactive Ion Etching (RIE), Micro Leakage Detection System (EMMI), X-Ray test, thiab Defect Incision and Observation System (FIB system) thiab lwm yam kev sim. Kev sim. Nws ua tiav qhov kev ntsuam xyuas thiab kev soj ntsuam ntawm qhov zoo ntawm cov khoom ntse thiab muab kev ruaj ntseg zoo rau chips, embedded software thiab kev siv cov khoom siv ntse.
