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 tuaj yeem txiav txim siab txog lub koob yees duab module ntawm koj cov khoom.
Peb tab tom 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 yuav pab tau.
Yuav xaiv lub koob yees duab module li cas
Qhov tseeb, lub lens dab tsi koj xav tau yog nyob ntawm qhov koj xav nruab koj lub koob yees duab / lub koob yees duab modules.Koj puas xav nruab rau hauv koj chav, koj lub chaw ua haujlwm, koj lub tsheb, koj lub Hoobkas loj, koj lub tiaj nraum qaum tsev, koj txoj kev, lossis koj lub tsev?Cov chaw sib txawv no nrog kev soj ntsuam sib txawv siv lub lens sib txawv, yog li yuav ua li cas xaiv qhov tsim nyog ntawm ntau pua lub lens sib txawv?
Muaj ntau yam xav txog thaum xaiv koj lub lens, xws li focal length, aperture, lens mount, format, FOV, lens siv thiab optical length, thiab lwm yam, tab sis nyob rau hauv tsab xov xwm no, kuv yuav hais txog ib qho tseem ceeb, qhov tseem ceeb tshaj plaws. Qhov tseem ceeb thaum xaiv lub lens: Lub Focal Length
Lub focal ntev ntawm lub lens yog qhov kev ncua deb ntawm lub lens thiab cov duab sensor thaum lub ntsiab lus tseem ceeb, feem ntau teev nyob rau hauv millimeters (xws li, 3.6 hli, 12 hli, los yog 50 hli).Nyob rau hauv cov ntaub ntawv ntawm zoom lo ntsiab muag, ob qhov tsawg kawg nkaus thiab siab tshaj plaws focal lengths tau teev, piv txwv li 2.8mm-12 mm.
Focal Length yog ntsuas hauv mm.Raws li kev qhia:
luv focal ntev (piv txwv li 2.8mm) = lub kaum sab xis ntawm qhov pom = luv kev soj ntsuam nrug
ib qhov ntev focal ntev (piv txwv li 16mm) = lub kaum sab xis ntawm qhov pom = ntev kev soj ntsuam nrug
Qhov luv ntawm qhov focal ntev, qhov ntau dua ntawm qhov xwm txheej tau ntes los ntawm lub lens.Ntawm qhov tod tes, qhov ntev ntawm qhov focal ntev, qhov me me ntawm lub lens ntes.Yog tias tib lub ntsiab lus tau yees duab los ntawm tib qhov kev ncua deb, nws qhov loj me me yuav txo qis vim qhov focal ntev tau luv dua thiab nce ntxiv thaum lub focal ntev ntev dua.
2 txoj kev sib txawv los ntim cov sensor
Ua ntej peb tau nqis mus rau kev tsim khoom ntawm ibkoob yees duab module, Nws yog ib qho tseem ceeb uas peb tau txais yuav ua li cas lub sensor tau ntim meej.Vim tias txoj kev ntim khoom cuam tshuam rau kev tsim khoom.
Sensor yog ib qho tseem ceeb ntawm lub koob yees duab module.
Hauv kev tsim cov txheej txheem ntawm lub koob yees duab module, muaj ob txoj hauv kev los ntim cov sensor: nti pob (CSP) thiab nti ntawm lub rooj tsavxwm (COB).
Chip nplai pob (CSP)
CSP txhais tau hais tias lub pob ntawm lub sensor nti muaj thaj tsam tsis muaj ntau dua 1.2 npaug ntawm cov nti nws tus kheej.Nws yog ua los ntawm cov chaw tsim khoom sensor, thiab feem ntau muaj txheej iav npog lub nti.
Chip on board (COB)
COB txhais tau hais tias cov nti sensor yuav raug txuas ncaj qha rau PCB (luam tawm Circuit board) lossis FPC (cov ntawv luam tawm yooj yim).COB txheej txheem yog ib feem ntawm lub koob yees duab module ntau lawm txheej txheem, yog li nws tau ua los ntawm lub koob yees duab module chaw tsim tshuaj paus.
Muab piv rau ob txoj kev ntim khoom, CSP txheej txheem nrawm dua, muaj tseeb dua, kim dua, thiab tuaj yeem ua rau lub teeb xa hluav taws xob tsis zoo, thaum COB ntau qhov chaw txuag, pheej yig dua, tab sis cov txheej txheem ntev dua, qhov teeb meem tawm los loj dua, thiab ua tsis tau. kho.
Kev tsim cov txheej txheem ntawm lub koob yees duab module
Rau lub koob yees duab module siv CSP:
1. SMT (nto mount technology): ua ntej npaj FPC, tom qab ntawd muab cov CSP rau FPC.Nws yog feem ntau ua nyob rau hauv ib tug loj teev.
2. Kev ntxuav thiab segmentation: ntxuav lub rooj tsav xwm loj loj ces txiav nws mus rau hauv cov qauv.
3. VCM (lub suab coil lub cev muaj zog) sib dhos: sib sau ua ke VCM rau tus tuav siv cov kua nplaum, tom qab ntawd ci lub module.Solder tus pin.
4. Lens sib dhos: sib sau lub lens mus rau tus tuav siv cov kua nplaum, ces ci lub module.
5. Tag nrho cov khoom sib dhos: muab lub lens module rau hauv Circuit Court board los ntawm ACF (anisotropic conductive film) bonding tshuab.
6. Lens tshuaj xyuas thiab tsom.
7. QC tshuaj xyuas thiab ntim khoom.
Rau lub koob yees duab module siv COB:
1. SMT: npaj FPC.
2. Ua COB txheej txheem:
Tuag bonding: khi lub sensor nti rau FPC.
Hlau bonding: khi ntxiv hlau los kho lub sensor.
3. Txuas mus rau VCM lub rooj sib txoos thiab cov txheej txheem seem yog tib yam li CSP module.
Qhov no yog qhov kawg ntawm tsab ntawv no.Yog koj xav paub ntxiv txogOEM koob yees duab module, xwbtiv tauj peb.Peb zoo siab tau hnov los ntawm koj!
