Yuav ua li cas xam lub microscope tag nrho magnification?
Tej zaum qee tus neeg yuav hais tias qhov no tsis yog qhov teeb meem yooj yim heev, tab sis qhov tseeb nws tseem nyuaj me ntsis.
Ua ntej tshaj plaws, cia peb muab piv txwv: thaum qhov kev nthuav dav ntawm lub qhov muag ntawm lub stereomicroscope yog 10 npaug, qhov zoom ntau ntawm lub cev qhov sib txawv ntawm qhov sib txawv yog 0.7X-4.5X, thiab lub hom phiaj ntxiv yog 2X, ces nws qhov kev nthuav dav optical yog 10 npaug ntawm 0.7 npaug 2. Qhov tsawg kawg nkaus magnification ntawm 4 lub sij hawm yog 4.5x, thiab qhov tsawg kawg nkaus magnification ntawm 4 lub sij hawm yog 1 zaug. 2, uas yog 90x. Yog li ntawd, tag nrho cov optical magnification ntawm no stereomicroscope yog 14 zaug rau 90 zaug. Ntawm chav kawm, qhov no tsuas yog qhov tseeb magnification ntawm lub microscope mainframe. Tom ntej no yog qhov kev nthuav dav digital ntawm lub tshuab microscope.
Piv txwv li, yog tias qhov loj ntawm tus saib yog 17 ntiv tes thiab 1/3 lub koob yees duab microscope siv, qhov kev nthuav dav digital ntawm lub koob yees duab microscope raws li qhia hauv cov lus hauv qab no yog 72 zaug. Cov mis rau kev suav cov digital magnification ntawm lub tshuab tsom iav yog: raws li kev teeb tsa ntawm lub tso suab tso suab lub tshuab ntsuas saum toj no, qhov sib txawv ntawm qhov sib txawv yog 0.7X-4.5X, lub hom phiaj ntxiv yog 2X, thiab lub koob yees duab eyepiece yog 1 (yog tias lub koob yees duab eyepiece tsis muaj qhov loj, nws tsis tas yuav suav nrog hauv kev suav). Raws li cov qauv: lub hom phiaj lens X lub koob yees duab eyepiece magnification X digital magnification, qhov tsawg kawg nkaus digital magnification yog 0.7 zaug 2 zaug 1 zaug 72, uas sib npaug 100.8 npaug, thiab qhov siab tshaj plaws digital magnification yog 4.5 npaug 2 zaug 72 zaug, uas sib npaug 648 npaug ntawm qhov kev nthuav dav digital yog los ntawm 100.8 zaug.
Hauv qhov no, ob lub qauv yuav tshwm sim:
1. Optical tag nrho magnification= eyepiece magnification X lub hom phiaj magnification
2. Digital tag nrho magnification=objective lens X lub koob yees duab eyepiece magnification X digital magnification
Cov mis no haum rau txhua lub tshuab ntsuas, txawm tias nws yog lub tshuab ntsuas metallographic, lub tshuab kuaj kab mob lom neeg, thiab lwm yam.

IC Failure Analysis Laboratory
Lub Beiruan Test Intelligent Product Testing Laboratory tau muab tso rau hauv kev ua haujlwm thaum kawg ntawm 2015 thiab muaj peev xwm ua haujlwm kuaj raws li cov qauv thoob ntiaj teb, hauv tsev, thiab kev lag luam. Nws ua tiav kev sim ua haujlwm los ntawm cov chips hauv qab mus rau cov khoom tiag, los ntawm physics mus rau logic. Nws muab cov kev pabcuam kuaj kev ruaj ntseg xws li nti ua ntej, kev tawm tsam sab nraud, kev tawm tsam kho qhov muag, kev tawm tsam, ib puag ncig, kev tiv thaiv hluav taws xob, kev txhaj tshuaj electromagnetic, kev txhaj tshuaj hluav taws xob, kev ruaj ntseg ntawm lub cev, kev ruaj ntseg logic, kev ua haujlwm, kev sib raug zoo, thiab ntau yam -point laser txhaj. Nyob rau tib lub sijhawm, nws tuaj yeem simulate thiab rov tsim dua qhov tshwm sim ntawm cov khoom lag luam ntse tsis ua haujlwm, txheeb xyuas qhov ua tsis tiav, thiab muab cov kev pabcuam tsis ua haujlwm thiab kuaj kev pabcuam, feem ntau suav nrog Chaw Nres Nkoj, Reactive Ion Etching (RIE), Micro Leakage Detection System (EMMI), X-Ray testing, thiab Defect Cutting Observation System (FIB). Kev ntsuam xyuas qhov system thiab lwm yam kev kuaj xyuas. Paub txog qhov kev ntsuam xyuas thiab kev txheeb xyuas qhov zoo ntawm cov khoom ntse, muab kev ruaj ntseg zoo rau cov chips, embedded software, thiab kev siv cov khoom siv ntse.
