Txij li thaumlub koob yees duab moduleua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, cia peb kawm ntxiv txog nws kom koj thiaj li txiav txim siab tau zoo txog lub koob yees duab module ntawm koj cov khoom.
Peb yuav muab qee cov lus qhia thiab cov txheej txheem tsim khoom ntawm lub koob yees duab module hauv cov ntsiab lus hauv qab no. Vam tias nws yuav pab tau.
Yuav ua li cas xaiv lub koob yees duab module kom raug
Qhov tseeb, lub lens twg koj xav tau feem ntau nyob ntawm seb koj xav teeb tsa koj lub koob yees duab / lub koob yees duab modules qhov twg. Koj puas xav teeb tsa nws hauv koj chav, koj chaw ua haujlwm, koj lub tsheb, koj lub Hoobkas loj, koj lub vaj tom qab, koj txoj kev, lossis koj lub tsev? Cov chaw sib txawv no nrog qhov deb saib sib txawv siv lub lens sib txawv heev, yog li yuav ua li cas xaiv qhov tsim nyog ntawm ntau pua lub lens sib txawv?
Muaj ntau yam yuav tsum xav txog thaum xaiv koj lub lens, xws li qhov ntev ntawm lub lens, qhov aperture, qhov mount ntawm lub lens, hom ntawv, FOV, kev tsim kho lub lens thiab qhov ntev ntawm lub lens, thiab lwm yam, tab sis hauv tsab xov xwm no, kuv yuav hais txog IB qho tseem ceeb, qhov tseem ceeb tshaj plaws thaum xaiv lub lens: Qhov Ntev Ntawm Lub Lens
Qhov ntev ntawm lub lens yog qhov deb ntawm lub lens thiab lub sensor duab thaum tus neeg raug tsom mus rau, feem ntau hais hauv millimeters (piv txwv li, 3.6 mm, 12 mm, lossis 50 mm). Hauv cov lens zoom, ob qho tib si qhov ntev tsawg kawg nkaus thiab siab tshaj plaws tau hais, piv txwv li 2.8mm–12 mm.
Qhov Focal Length ntsuas hauv mm. Ua ib qho kev qhia:
qhov ntev ntawm lub lens luv (piv txwv li 2.8 hli) = lub kaum sab xis dav = qhov deb ntawm kev soj ntsuam luv
qhov ntev ntawm lub focal (piv txwv li 16mm) = lub kaum sab xis nqaim = qhov deb ntawm kev soj ntsuam ntev
Qhov luv dua qhov focal length, qhov dav ntawm qhov scene uas lub lens ntes tau yuav loj dua. Ntawm qhov tod tes, qhov ntev dua qhov focal length, qhov dav dua qhov lens ntes tau yuav me dua. Yog tias tib yam khoom raug thaij duab los ntawm tib qhov deb, nws qhov loj me yuav txo qis thaum qhov focal length luv dua thiab nce ntxiv thaum qhov focal length ntev dua.
2 txoj kev sib txawv los ntim lub sensor
Ua ntej peb mus rau qhov txheej txheem tsim khoom ntawm ib qholub koob yees duab module, nws yog ib qho tseem ceeb uas peb tau txais qhov tseeb tias lub sensor tau ntim li cas. Vim tias txoj kev ntim khoom cuam tshuam rau cov txheej txheem tsim khoom.
Lub sensor yog ib qho tseem ceeb hauv lub koob yees duab module.
Hauv cov txheej txheem tsim khoom ntawm lub koob yees duab module, muaj ob txoj hauv kev los ntim lub sensor: pob khoom ntsuas chip (CSP) thiab chip on board (COB).
Pob khoom ntsuas nti (CSP)
CSP txhais tau hais tias lub pob ntawm lub sensor chip muaj thaj tsam tsis pub tshaj 1.2 npaug ntawm lub chip nws tus kheej. Nws yog ua los ntawm lub chaw tsim khoom sensor, thiab feem ntau muaj ib txheej iav npog lub chip.
Chip on board (COB)
COB txhais tau tias lub sensor chip yuav raug txuas ncaj qha rau PCB (printed circuit board) lossis FPC (flexible printed circuit). Cov txheej txheem COB yog ib feem ntawm cov txheej txheem tsim cov koob yees duab module, yog li nws tau ua los ntawm lub chaw tsim khoom module koob yees duab.
Piv rau ob txoj kev xaiv ntim khoom, CSP txheej txheem yog sai dua, raug dua, kim dua, thiab tej zaum yuav ua rau lub teeb tsis zoo, thaum COB txuag chaw ntau dua, pheej yig dua, tab sis cov txheej txheem ntev dua, qhov teeb meem loj dua, thiab tsis tuaj yeem kho tau.
Cov txheej txheem tsim khoom ntawm lub koob yees duab module
Rau lub koob yees duab module siv CSP:
1. SMT (surface mount technology): Ua ntej npaj FPC, tom qab ntawd txuas CSP rau FPC. Feem ntau ua tiav hauv qhov loj.
2. Kev ntxuav thiab kev faib ua feem: ntxuav lub rooj tsavxwm loj ces txiav nws ua tej daim me me.
3. VCM (lub cev muaj zog lub suab): sib dhos VCM rau ntawm lub tuav siv kua nplaum, tom qab ntawd ci lub module. Siv lub hlau nplaum los txuas lub pin.
4. Kev sib dhos lub lens: sib dhos lub lens rau ntawm lub tuav siv kua nplaum, tom qab ntawd ci lub module.
5. Tag nrho cov module sib dhos: txuas lub lens module rau lub rooj tsavxwm los ntawm ACF (anisotropic conductive film) bonding tshuab.
6. Kev tshuaj xyuas lub lens thiab kev tsom mus rau qhov muag.
7. Kev tshuaj xyuas QC thiab ntim khoom.
Rau lub koob yees duab module siv COB:
1. SMT: npaj FPC.
2. Ua cov txheej txheem COB:
Kev sib txuas ntawm cov tuag: txuas cov sensor chip rau ntawm FPC.
Kev sib txuas ntawm cov hlau: txuas cov hlau ntxiv kom kho qhov sensor.
3. Txuas ntxiv mus rau VCM sib dhos thiab cov txheej txheem seem yog tib yam li CSP module.
Nov yog qhov kawg ntawm tsab ntawv no. Yog tias koj xav paub ntxiv txogOEM lub koob yees duab module, tsuas yogtiv tauj pebPeb zoo siab hnov los ntawm koj!
