CCD (them nyiaj {{{- Daim ntawv qhia txuas ntxiv) Cov koob yees duab nyob twj ywm los ntawm ob tus kws tshaj lij thiab cov vintage zoo nkauj. Txawm li cas los xij, cov khoom siv precision yog nkag siab rau ib puag ncig thiab kev siv kev siv. Kev saib xyuas kev tshawb fawb tuaj yeem txuas ntxiv lawv lifespan thiab khaws cia cov duab zoo.
Kev tu txhua hnub cia
CCD cov koob yees duab yuav tsum tau muab cia rau hauv ib puag ncig qhuav, zoo kawg nkaus nrog cov av noo ntawm 40% thiab 50%, thiab qhov kub ntawm 10℃thiab 25 degree. Thaum ntev - sij hawm cia, ib txwm tshem cov roj teeb kom tiv thaiv tsis taus dej xau thiab corrosion ntawm lub voj voog. Siv noo noo {- cov ntawv pov thawj los yog ntim hnab nrog lub hnab ntim khoom nrog desiccant (xws li Silica Gel). Yog tias cov neeg mob tso cai, lub hwj chim ib ntus ntawm lub koob yees duab los ua kom muaj noo noo.
Kho kom zoo thiab kho
Lub lens thiab sensor yog cov tseem ceeb ntawm CCD koob yees duab. Thaum tu lub lens, thawj zaug siv cov cua daj cua dub kom tshem tawm txhua daim ntaub ntub dej, ces maj mam so nrog cov tshuaj microfiber Sensor Tu yuav tsum tau saib xyuas ntxiv thiab tsis pom zoo rau qhov tsis- kws tshaj lij. Yog tias tsim nyog, siv ib qho anti - zoo li txhuam thiab lub sensor -} ib puag ncig} ib puag ncig. Lub cev yees duab tau muab ntxuav nrog cov ntaub mos mos me ntsis, tab sis zam dhau ntawm qhov khoob ntawm cov chaw nres nkoj thiab khawm.
Kev siv tus cwj pwm cuam tshuam rau lub koob yees duab lub neej.
Txheeb xyuas cov neeg ntawm daim npav nco thiab roj teeb rau oxidation ua ntej siv. Kev tiv tauj tsis zoo yuav ua rau cov ntaub ntawv poob lossis ntaus ntawv tsis ua haujlwm. Zam kev tua neeg nyob rau hauv plua plav, siab - noo noo ib puag ncig, lossis hauv huab cua sov hloov pauv. Piv txwv li, thaum dheev txav los ntawm ib puag ncig sab nraum zoov mus rau ib puag ncig sab hauv tsev, cia lub koob yees duab kom muaj qhov ntsuas kub kom tiv thaiv kom tiv thaiv hws. Thaum tsis siv sijhawm ntev, nws raug nquahu kom lub hwj chim ntawm lub koob yees duab thiab xeem nws txhua 3-6 lub hlis, thiab hloov kho cov firmware (yog tias txhawb).
Kev txij nkawm yog qhov tseem ceeb.
Yog tias kev sim ua rau txawv txawv (xws li dawb me ntsis lossis ntau dua cov suab nrov) lossis cov tshuab ua tsis tiav tshwm sim, lub koob yees duab yuav tsum tau kho kom sai. Disassembly tuaj yeem puas cov kev puas tsuaj cov cheebtsam, tshwj xeeb tshaj yog cov ntsaws ruaj khov ib ncig ntawm CCD sensor. Tsis tu ncua xa lub koob yees duab mus rau kev tshaj lij rau kev tu thiab ntsuas hluavtaws yuav tswj hwm nws txoj kev ua haujlwm kho qhov muag.
Los ntawm kev siv cov txheej txheem saum toj no, CCD cov koob yees duab tsis tuaj yeem tswj hwm cov haujlwm ruaj khov, tab sis kuj khaws lawv txoj kev xav tau zoo rau lub sijhawm ntev. Kev saib xyuas kev tshawb fawb tsis yog tsuas yog tiv thaiv cov khoom siv, tab sis kuj tseem yuav hwm cov kos duab kos duab.
