Kodi LCD TV Mainboard CKD ndi chiyani?

Mu unyolo wapadziko lonse wa ma TV a LCD, CKD ndi mawu ogwiritsidwa ntchito kwambiri pamalonda, makamaka pa ma TV mainboards—gawo lalikulu. Mtundu wa CKD wakhala njira yodziwika bwino yopangira zinthu kunja kwa dziko, kuchepetsa ndalama, kukonza magwiridwe antchito komanso kutsatira mfundo zamalonda zakomweko.

Kodi CKD ndi chiyani kwenikweni?

CKD imayimira Completely Knocked Down. Pa ma TV mainboard a LCD, zikutanthauza kutumiza ma circuit board opanda kanthu + zida zonse zamagetsi + zikalata zaukadaulo m'malo mwa ma mainboard omalizidwa. Dziko lotumiza limamaliza kuyika ma SMT, kusungunula, kukonza zolakwika ndikuyesaku mafakitale akumaloko kuti apange ma mainboards omwe angagwiritsidwe ntchito.

Mwachidule: CKD = seti yonse ya "zida zogwirira ntchito" za mainboard zopangira ndi kusonkhanitsa zinthu zakomweko.

Kodi Chida Chogwiritsira Ntchito CKD cha LCD TV Mainboard Chimaphatikizapo Chiyani?

Bolodi yaikulu ya PCB yopanda kanthu: Palibe gawo lamagetsi lomwe layikidwa kales

Zipangizo zamagetsi zonse za BOM: Main chips, DDR memory, flash memory, resistors, capacitors, HDMI/USB/Ethernet ports, key panels, receivers, cables, heat sinks ndi zina zambiri

Zikalata zaukadaulo zopangira: Zojambula za malo, zojambulajambula, firmware, mapulogalamu oyesera ndi malangizo a njira zopangira

Kupaka ndi zowonjezera: Kupaka kosagwirizana ndi malo, mndandanda wazolongedza, zilembo ndi zinthu zina zothandizira

Palibe njira zokonzera zinthu zomwe zaphatikizidwa; njira zonse zopangira zinthu zimamalizidwa kudziko lomwe mukufuna kupitako.

Kusiyana Pakati pa CKD, SKD ndi Ma Mainboard Omalizidwa

CKD (Yogwetsedwa Konse): Bolodi lopanda kanthu + zigawo zonse → SMT yakomweko, kusungunula ndi kuyesa; mitengo yotsika kwambiri, yoyenera kumanga fakitale yakomweko

SKD (Semi-Knocked Down): Zigawo zazikulu zimayikidwa kale pa bolodi lalikulu → kuyika zigawo zazing'ono zokha ndikuyesa mosavuta m'deralo; kupanga mwachangu, koyenera magulu ang'onoang'ono mpaka apakati

Bodi Yaikulu Yomalizidwa: Yosonkhanitsidwa bwino ndipo yokonzeka kuyikidwa; yabwino kwambiri koma yokwera mtengo kwambiri

Chifukwa chiyaniCKDAmagwiritsidwa Ntchito Kwambiri Pamalonda Akunja?

Kuchepetsa kwakukulu kwa mitengo: Mayiko ambiri amaika mitengo ya 15%–35% pa zinthu zomwe zamalizidwama board akuluakulu, koma 0%–5% yokha pa ziwalo za CKD

Kutsatira mfundo za "kupanga zinthu zakomweko": Kuyenerera kulandira thandizo la ndalama, mitengo yabwino yamagetsi komanso kuchotsera mwachangu katundu wa pa kasitomu ku Southeast Asia, Middle East, Africa, Europe ndi madera ena.

Ndalama zotumizira zochepa: Kulemera kochepa komanso kopepuka kuposa ma mainboards omalizidwa kumachepetsa ndalama zoyendera

Kusintha kosinthika: Kusintha kwa chilankhulo cha dongosolo, magawo a zithunzi ndi miyezo ya chizindikiro (DVB-T, ATSC, DTMB, ndi zina zotero) kuti zigwirizane ndi misika yosiyanasiyana

Kukonza zinthu mosavuta mukamaliza kugulitsa ndi m'deralo: Kupereka zida zogwirizanitsa kumathandiza kusintha zinthu mwachangu popanda kudalira mafakitale akunja.
