Kedu ihe bụ LCD TV Mainboard CKD?

N'ime usoro nnyefe TV LCD zuru ụwa ọnụ, CKD bụ okwu azụmaahịa a na-ejikarị eme ihe, ọkachasị maka bọọdụ TV—isi ihe dị mkpa. Ụdị CKD aghọwo ihe ngwọta a ma ama maka mmepụta mba ofesi, mbelata ọnụ ahịa, mmezi arụmọrụ na ịgbaso iwu azụmaahịa mpaghara.

Gịnị kpọmkwem bụ CKD?

CKD pụtara Completely Knocked Down. Maka LCD TV mainboards, ọ pụtara mbupụ bọọdụ sekit efu + ihe niile eletrọnịkị + akwụkwọ teknụzụ kama ịbụ ndị emechara emechara. Mba mbubata na-emecha nrụnye SMT, ịgbado ọkụ, debugging nannwalen'ụlọ ọrụ mmepụta ihe dị n'ógbè ahụ iji mepụta bọọdụ ndị a na-eji arụ ọrụ.

Na nkenke: CKD = ngwa ọrụ "ihe ndị dị mkpa" zuru oke maka mmepụta na mgbakọ mpaghara.

Kedu ihe Ngwa CKD nke LCD TV Mainboard gụnyere?

Ogwe isi PCB efu: Enweghị akụkụ eletrọniki arụnyere tupu oge eruos

Ihe eletrọniki BOM zuru oke: Isi ibe, ebe nchekwa DDR, ebe nchekwa flash, resistors, capacitors, ọdụ ụgbọ mmiri HDMI/USB/Ethernet, panel igodo, ndị nnata, eriri, sink okpomọkụ na ihe ndị ọzọ

Akwụkwọ teknụzụ mmepụta: Eserese ebe, eserese, firmware, ngwanrọ nnwale na ntuziaka usoro mmepụta

Nkwakọ ngwaahịa na ngwa: Nkwakọ ngwaahịa mgbochi-static, ndepụta nkwakọ ngwaahịa, akara na ihe enyemaka ndị ọzọ

A naghị etinye usoro nhazi ọ bụla; a na-emecha usoro mmepụta ihe niile na mba ebe a na-aga.

Ihe dị iche n'etiti CKD, SKD na Mainboards Emechara

CKD (Akụkụchaala kpamkpam): Obodo efu + ihe niile → SMT mpaghara, ịgbado ọkụ na nnwale; ọnụego kacha ala, dị mma maka owuwu ụlọ ọrụ mpaghara

SKD (Semi-Knocked Down): A na-etinye ihe ndị bụ isi na mainboard → naanị ntinye obere akụkụ na nnwale dị mfe n'ógbè; mmepụta ngwa ngwa, dabara adaba maka obere obere na ọkara batches

Emechara Mainboard: Achịkọtara ya nke ọma ma dị njikere maka nrụnye; ọnụego kachasị mma mana kachasị elu

Gịnị mereCKDA na-eji ya eme ihe n'ọtụtụ ebe n'ahịa mba ọzọ?

Mbelata nnukwu ụgwọ ọrụ: Ọtụtụ mba na-etinye ụtụ isi 15%–35% mgbe emechara yaisi bọọdụ, mana naanị 0%–5% na akụkụ CKD

Nrubeisi na atumatu "mmepụta mpaghara" nke mpaghara: Ndị ruru eru maka enyemaka ego, ọnụego ọkụ eletrik kacha mma na nhazi ngwa ngwa nke kọstọm na Ndịda Ọwụwa Anyanwụ Eshia, Middle East, Africa, Europe na mpaghara ndị ọzọ

Ọnụ ego mbupu dị ala: Olu pere mpe na ibu dị mfe karịa isi ihe eji emechara belata mmefu njem

Nhazi dị mfe: Nhazi mpaghara nke asụsụ sistemụ, paramita foto na ọkọlọtọ akara (DVB-T, ATSC, DTMB, wdg) iji dabara na ahịa dị iche iche

Ọ dị mfe mgbe a gbasịrị ahịa na mmezi mpaghara: Inye akụkụ dị n'otu na-eme ka a gbanwee ngwa ngwa na-enweghị ịdabere na ụlọ ọrụ mmepụta ihe si mba ofesi.
