Ib tug tshiabkoob yees duab moduletej zaum yuav ua hauj lwm zoo kawg nkaus thaum xub thawj. Tab sis nws puas tseem ua haujlwm ruaj khov tom qab lub hlis ntawm kev siv tas li, cua sov, lossis kev co? Qhov ntawd yog dab tsi akoob yees duab module aging testyog rau. Los ntawm kev khiav cov modules nyob rau hauv kev ntxhov siab ntxiv, manufacturers tuaj yeem ntes cov kev ua tsis tiav thaum ntxov thiab kwv yees tias lawv yuav kav ntev npaum li cas. Kab lus no piav qhia txog kev kuaj kev laus li cas, vim li cas nws tseem ceeb rau cov qauv sib txawv - los ntawm ame koob yees duab modulenyob rau hauv ib tug drone rau ib4K koob yees duab modulerau kev ruaj ntseg - thiab nws ua li cas.
Qhov Kev Ntsuas Kev Laus Yog Dab Tsi?
Ib qho kev kuaj kev laus (tseem hu ua burn-in los yog kev ntsuam xyuas kev ntseeg tau) tso ib qhokoob yees duab modulenyob rau hauv kev nyuaj siab - kub siab, voltage, los yog on / off cycling - kom ceev cov laus. Lub hom phiaj yog ua kom muaj qhov tsis xws luag (cov pob qij txha tsis muaj zog, cov khoom siv qias neeg qias neeg, cov lo ntsiab muag tsis ruaj khov) tshwm sim hauv cov xuab moos lossis hnub tsis yog hli.
Rau ibCMOS Lub Koob Yees Duab Module, cov kev nyuaj siab ntau yog:
Kub kub (60-85 degree)
Kub caij tsheb kauj vab (-40℃rau +85 degree)
Nruam video streaming (24-168 teev)
Lub zog cycling (on / off dua)
Vim Li Cas Thiaj Ua Kev Laus?
Yog tsis muaj lawv, akoob yees duab moduletej zaum yuav ua tsis tau tom qab koj cov neeg siv khoom yuav nws - ua rau rov qab los, kev tshuaj xyuas tsis zoo, lossis teeb meem kev nyab xeeb. Kev kuaj kev laus pab:
Nrhiav cov teeb meem hauv lub neej thaum ntxov uas yuav tshwm sim tom qab.
Tshawb xyuas thermal stability - lub lens puas nyob hauv tsom tom qab cov sij hawm cua sov?
Kev ntsuas kev sib txuas - cables, solder joints, bond wires.
Xyuas kom muaj kev ua tau zoo mus ntev – tseem ceeb rau kev siv kho mob, tsheb, lossis kev siv kev nyab xeeb.
Hom Kev Xeem Kev Laus
| Kuaj | Nws Ua Dab Tsi | Nrhiav tau |
|---|---|---|
| Kev ua haujlwm kub kub (HTOL) | Khiav ntawm 60-85℃thaum streaming video rau 48-168 teev | Tsis muaj zog solder pob qij txha, sensor suab, teeb meem lo ntsiab muag |
| Kub caij tsheb kauj vab | Lub voj voog ntawm −40℃thiab +85℃(30-60 cycles) | Cracking solder, delamination, tsom hloov |
| Lub zog caij tsheb kauj vab | Qhib / tawm txhua ob peb vib nas this, ntau txhiab zaus | Fais fab-on reset teeb meem, USB enumeration tsis ua hauj lwm |
| Kev ua haujlwm tsis tu ncua (chav temp) | Khiav ib txwm rau 7-30 hnub | Kev ua haujlwm qis qis, plua plav nkag |
Yuav Ua Li Cas Kev Xeem Kev Laus Ua tiav
Hom kev teeb tsa:
Lub qhov cub uas tswj tau qhov kub thiab txias los yog cycling chamber.
Ib qho system los ntes cov duab los ntawm txhua tuskoob yees duab moduledhau sijhawm.
Lub zog thiab cov ntaub ntawv sib txuas (USB, MIPI).
Software los teev qhov yuam kev thiab cov duab zoo (ntse, suab nrov, pixels tsis zoo).
Cov kauj ruam:
- Thawj daim tshev- ntes cov duab siv.
- Kev nyuaj siab theem- muab cov modules tso rau hauv lub chamber ntawm qhov kub thiab txias, streaming video lossis thaij duab tsis tu ncua.
- Kev kuaj xyuas ib ntus- Thaum lub sij hawm teem, sib piv cov duab rau kev siv.
- Kev kuaj zaum kawg- Tom qab qhov kev xeem, nrhiav kev degradation.
- Pass / poob- teeb tsa cov cai (piv txwv li, tsis muaj cov pixels tuag tshiab, tsom rau hauv spec).
- Kev Xeem Kev Laus rau ntau hom Module
Lub koob yees duab me me
A me koob yees duab modulenyob rau hauv ib lub smartwatch los yog me me drone muaj qhov chaw me me rau cua txias. Kev ntsuam xyuas kev laus ntawm 70℃rau 72 teev qhia yog tias lub sensor overheats lossis lub lens nplaum softens.
CMOS Lub Koob Yees Duab Module
Feem ntauCMOS Lub Koob Yees Duab Modulesensors raug ntsuas 0-70℃(neeg siv) lossis −40-105℃(kev lag luam). Kev ntsuam xyuas kev laus yuav tsum siv qhov kawg ntawm qhov kub thiab txias los xyuas tag nrho cov kev sib dhos - lub lens, flex cable, connectors - tsis yog lub sensor xwb.
4K Lub Koob Yees Duab Module
A 4K koob yees duab modulemuaj ntau ntau pixels thiab siab dua cov ntaub ntawv ceev. Kev ntsuam xyuas kev laus tsom rau:
Cov teeb liab zoo - cov kab ntawv puas poob cov ntaub ntawv thaum kub?
Lens daws teeb meem - lub lens puas nyob twj ywm tom qab kub ntxhov?
Kev Ua Haujlwm - Puas yog ISP overheat encoding 4K video tsis nres?
Dab tsi Yog Txais Tom Qab Kev Xeem Kev Laus?
Tom qab kev xeem, akoob yees duab moduleyuav tsum muaj:
Tsis ntau tshaj 0.001% tshiab tuag lossis kub pixels.
Kev tsom xam ua haujlwm tsawg dua 5% ntawm qhov tob ntawm qhov chaw.
Xim yuam kev ΔE <5 nyob rau hauv lub teeb txheem.
Tsis muaj kab nrib pleb, discoloration, los yog xoob qhov chaw.
Rau ib4K koob yees duab module, sharpness yuav tsum tsis txhob poob qis dua 80% ntawm tus nqi qub.
