Popezagawo la kameraImagwira ntchito yofunika kwambiri pazinthu zamagetsi, tiyeni tiphunzire zambiri za izo kuti muthe kupanga zisankho zoyenera pankhani ya kamera ya zinthu zanu.
Tipereka malangizo ndi njira yopangira kamera mu izi. Tikukhulupirira kuti zithandiza.
Momwe mungasankhire kamera yoyenera
Ndipotu, lenzi yomwe mukufuna imadalira kwambiri komwe mukufuna kuyika makamera/ma module a kamera yanu. Kodi mukufuna kuiyika m'chipinda chanu, muofesi yanu, m'magalimoto anu, m'fakitale yanu yayikulu, kumbuyo kwanu kotseguka, mumsewu wanu, kapena m'nyumba mwanu? Malo osiyanasiyana awa okhala ndi mtunda wosiyana wowonera amagwiritsa ntchito lenzi yosiyana kwambiri, ndiye mungasankhe bwanji yoyenera pakati pa mazana a lenzi zosiyanasiyana?
Pali zinthu zambiri zomwe muyenera kuganizira posankha lenzi yanu, monga kutalika kwa lenzi, kutsegula, kuyika lenzi, mawonekedwe, FOV, kapangidwe ka lenzi ndi kutalika kwa kuwala, ndi zina zotero, koma m'nkhaniyi, ndigogomezera chinthu CHIMODZI, chinthu chofunikira kwambiri posankha lenzi: Kutalika kwa Lenzi
Kutalika kwa lenzi ndi mtunda womwe umakhala pakati pa lenzi ndi sensa ya chithunzi pamene chinthucho chili mu focus, nthawi zambiri chimafotokozedwa mu mamilimita (monga 3.6 mm, 12 mm, kapena 50 mm). Pankhani ya ma zoom lens, kutalika kwa focus kocheperako komanso kwakukulu kumafotokozedwa, mwachitsanzo 2.8mm–12 mm.
Kutalika kwa Focal kumayesedwa mu mm. Monga chitsogozo:
kutalika kochepa kwa focal (monga 2.8mm) = ngodya yayikulu ya mawonekedwe = mtunda waufupi wowonera
kutalika kwa focal (monga 16mm) = ngodya yopapatiza ya mawonekedwe = mtunda wautali wowonera
Kutalika kwa focal kukafupika, kukula kwa malo omwe ajambulidwa ndi lenzi kumakulirakulira. Kumbali ina, kutalika kwa focal kukakulirakulira, kukula kwa focal kukafupikiranso. Ngati munthu yemweyo ajambulidwa kuchokera patali lomwelo, kukula kwake koonekera kudzachepa pamene kutalika kwa focal kukufupikira ndikuwonjezeka pamene kutalika kwa focal kukukulirakulira.
Njira ziwiri zosiyanasiyana zopakira sensa
Tisanayambe njira yopangiragawo la kamera, ndikofunikira kuti timvetse bwino momwe sensa imapakira. Chifukwa momwe amapakira zimakhudza momwe zinthu zimachitikira.
Sensor ndi gawo lofunikira mu gawo la kamera.
Mu njira yopangira kamera, pali njira ziwiri zopakira sensor: phukusi la chip scale (CSP) ndi chip on board (COB).
Phukusi la sikelo ya chip (CSP)
CSP imatanthauza kuti phukusi la chip ya sensor lili ndi malo osapitirira nthawi 1.2 kuposa chip yokha. Limapangidwa ndi wopanga masensa, ndipo nthawi zambiri pamakhala galasi lophimba chip.
Chip pa bolodi (COB)
COB imatanthauza kuti chip ya sensor idzalumikizidwa mwachindunji ku PCB (bolodi yosindikizidwa) kapena FPC (circuit yosindikizidwa yosinthika). Njira ya COB ndi gawo la njira yopangira kamera, motero imachitika ndi wopanga kamera.
Poyerekeza njira ziwiri zopakira, njira ya CSP ndi yachangu, yolondola, yokwera mtengo, ndipo ingayambitse kufalikira kwa kuwala koyipa, pomwe COB imasunga malo ambiri, yotsika mtengo, koma njira yake ndi yayitali, vuto la zokolola ndi lalikulu, ndipo silingakonzedwe.
Njira yopangira kamera
Pa kamera module pogwiritsa ntchito CSP:
1. SMT (ukadaulo woyika pamwamba): choyamba konzani FPC, kenako ikani CSP ku FPC. Nthawi zambiri imachitidwa pamlingo waukulu.
2. Kuyeretsa ndi kugawa magawo: yeretsani bolodi lalikulu lamagetsi kenako liduleni m'zidutswa wamba.
3. Kusonkhanitsa VCM (voice coil motor): kusonkhanitsa VCM ku chogwirira pogwiritsa ntchito guluu, kenako kuphika gawolo. Kulunzani pini.
4. Kusonkhanitsa ma lenzi: kusonkhanitsa ma lenzi ku chogwirira pogwiritsa ntchito guluu, kenako kuphika gawolo.
5. Kusonkhanitsa ma module onse: lumikizani ma module a lenzi ku bolodi la circuit kudzera mu makina olumikizira a ACF (anisotropic conductive film).
6. Kuyang'ana ndi kuyang'ana kwambiri magalasi.
7. Kuyang'anira ndi kulongedza QC.
Pa kamera module pogwiritsa ntchito COB:
1. SMT: konzani FPC.
2. Chitani njira ya COB:
Kulumikiza kwa Die: kumangirirani chip cha sensor pa FPC.
Kulumikiza waya: kumangirira waya wowonjezera kuti akonze sensa.
3. Pitirizani ku VCM assembly ndipo njira zina zonse ndi zofanana ndi CSP module.
Apa ndiye kumapeto kwa positi iyi. Ngati mukufuna kudziwa zambiri zaGawo la kamera la OEM, basiLumikizanani nafeTasangalala kumva kuchokera kwa inu!
