Taariikhda horumarinta warshadaha kiiboodhka farsamada ee Shiinaha
Warshadaha kiiboodhka farsamada ee ajnabiga ah waxay leeyihiin taariikh dheer.Summada kiiboodhka farsamada ee ugu horreysay adduunka, CHEERY, ayaa laga aasaasay Jarmalka 1953kii.
Intaa ka dib, CHERRY waxay ka dhistay 12 laamood iyo warshado gudaha Maraykanka iyo waddamo iyo gobollo kale.Inta badan kiiboodhka farsamada ee caadiga ah waxaa lagu soo saaraa warshadaha Jarmalka iyo Czech.Warshadaha kiiboodhka farsamada ee Shiinaha waxa ay bilaabeen wakhti dambe, iyaga oo soo baxay dabayaaqadii 1970-meeyadii, horumarkeeda waxa loo qaybin karaa marxalada gaysashada iyo heerka horumarka (1978-2010)
Laga soo bilaabo 1978 ilaa 2010, warshadaha kiiboodhka makaanikada ee Shiinaha waxay ahayd bilawgeedii.Marxaladdan, furayaasha farsamada ee ugu muhiimsan ee suuqa Shiinaha waxay ahaayeen
Si ay u soo saaraan warshado shisheeye oo ay u galaan suuqa Shiinaha qaab alaabada la dhammeeyey, noocyada kumbuyuutarka ee farsamada shisheeye ee caanka ah waxaa ka mid ah jarmalka CheERY,
Japan REALFORCE, US IBM, iwm. Noocyada kiiboodhka farsamaysan ee la soo saaray marxaladdan waxaa ka mid ah shixayaasha madow, furayaasha cagaaran, furayaasha brown,
dhidibka cas, dhidibka cad ee kiiboodhka farsamada, iwm. Waxaa ka mid ah, kiiboodhka dhidibka madaw ayaa marka hore soo muuqday, tignoolajiyada wax soo saarkuna waa qaan.Xawaaraha rasaasta furaha awgeed
Astaamaha xawaaraha degdega ah iyo dareenka sare ee kiiboodhka waxaa doorbida kuwa jecel ciyaarta waxayna si dhakhso ah u noqdaan kuwa caadiga ah "keyboard makaanik ciyaaraha".
Marxaladda horumarinta Tan iyo 2011, warshadaha kiiboodhka farsamada ee Shiinaha waxa ay ku jireen marxalad horumarineed.Marxaladdan, shirkadaha soo saara kiiboodhka farsamaysan ee gudaha iyo dibadda waxay bilaabeen inay warshado ka sameeyaan Shiinaha oo ay siiyaan noocyada kala duwan ee kiiboodhka farsamada ee kanaalada khadka iyo khadka tooska ah.Iyada oo ku saleysan baahida sii kordheysa ee kooxaha macaamiishu ee loogu talagalay raaxada furayaasha farsamada, kiiboodhka farsamada ee casaanka, cagaarka iyo buniga ah ayaa horumaray iyadoo lagu salaynayo kiiboodhka dhidibka madow si tartiib tartiib ah u bedelay kiiboodhka farsamada ee dhidibka madow oo noqday mid caan ah.Kiiboodhka dhidibka cad si tartiib tartiib ah ayuu uga baxayaa suuqa, kaliya Waxa uu u muuqdaa alaab la habeeyey.Intaa waxaa dheer, noocyada kumbuyuutarrada farsamada ayaa si joogto ah loo kobciyaa, shirkadaha la xidhiidha waxay sii wadaan inay abuuraan marka la eego muraayadaha kiiboodhka, saamaynta iftiinka RGB, qaababka, qalabka furaha iyo teknoolojiyadda dheeraadka ah, taasoo keentay noocyo cusub oo kiiboodhka farsamada ah sida kiiboodhka farsamada RGB iyo magnetka. beddel kiiboodhka farsamada..
Ka qaybqaatayaasha sare ee silsiladda warshadaha ee warshadaha kiiboodhka farsamada ee Shiinaha waa alaab-qeybiyeyaal alaabta ceeriin ah, taas oo ah, si ay u bixiyaan adeegyada wax soo saarka iyo soosaarka kiiboodhka farsamada.
Ganacsade alaabta ceeriin ee daruuriga ah.Alaabta ceeriin ee ku lug leh soo saarista kiiboodhka farsamada waxaa ka mid ah shafts, MCU (kumbuyuutarka heerka-chip), PCB (daabacan).
looxyada wareegyada), koofiyadaha, iwm. Waxaa ka mid ah, usheeda dhexe waa alaabta ceeriin ee ugu weyn ee kiiboodhka farsamada, qiimahiisuna waa saamiga wadarta qiimaha kiiboodhka farsamada
Qiyaastii 30%, qiimaha alaabta ceeriin sida MCU, PCB, keycaps ayaa xisaabiya 10%, 10%, 5 ~ 8% wadarta qiimaha.
(1) dhidibka:
Shirkadaha waaweyn ee Shiinaha ee soo saara furaha gaarka ah ee kiiboodhka farsamada waxaa ka mid ah Kaihua, Gaote, iyo Guantai, kuwaas oo si wada jir ah u qaada furaha kiiboodhka farsamada.
Saamiga suuqu waa ilaa 70%, saamaynta warshaduhu waa mid xoogan, iyo awooda gorgortanka ee ka qaybgalayaasha meelaha dhexe ee silsilada warshadaha kiiboodhka farsamada
sareTirada soo saarayaasha usheeda dhexe ee kiiboodhka makaanik ee dalka Shiinaha ayaa ah mid aad u yar, iyada oo wadarta guud ay ka badan tahay 100, xooga saarida warshaduhuna waa mid aad u sarreeya.
(2) MCU:
MCU waa kombuyuutar heer-sare ah oo isku-dhafan is-dhex-galayaasha sida xusuusta, miiska, iyo USB-ga hal chip.dhexe
Kiiboodhka farsamaysan ee Shiinaha ee MCU-yada waxay u badan yihiin 8-bit MCUs, marka la barbar dhigo 32-bit MCUs (inta badan loo isticmaalo hawlaha shabakada, farsamaynta warbaahinta badan, iwm.
Xaaladaha habaynta adag) waa kuwo aad u hooseeya oo tignoolajiyada hooseeya.Marxaladdan, soosaarayaasha 8-bit MCU ee leh saamiga suuqa sare ee Shiinaha waxaa ka mid ah Atmel, NXP, STC, Winbond, iwm. Sababo la xiriira tignoolajiyada hoose ee tignoolajiyada, warshado badan oo yar yar oo Shiinaha ah ayaa soo baxay oo sii waday horumarinta, iyo xoojinta suuqa Warshadaha Shiinaha ee 8-bit MCU waa hooseeyaa, awoodda gorgortanka ee shirkadaha wax soo saarka ayaa hooseeya.
(3) PCB:
PCB waxaa loola jeedaa looxa wareeg ah oo daabacan oo isku xira jirka ugu weyn iyo shafka oo sidoo kale taageera shafka.Shiinaha PCB-fiirsashada suuqa warshadaha waa hooseeya, Shiinaha
Waxaa jira warshado badan oo maxalli ah.Shirkadaha PCB waxay ku urursan yihiin Guangdong, Hunan, Hubei, Jiangxi, Jiangsu iyo meelo kale, oo matalaya shirkadaha
Waxaa jira Zhending Technology, Shennan Circuit, Technology Lianneng, Shenzhen Wuzhu Technology, iwm marka la barbar dhigo warshadaha dhidibka keyboard farsamo, China PCB
Raasamaal wershadaha iyo marinnada farsamada ayaa hooseeya, awoodda sahayda suuqyaduna way ka weyn tahay baahida dhabta ah, markaa awoodda gorgortanka ee shirkadaha PCB waa mid hooseeya.
(4) Koofiyadaha:
Koofiyadaha kiiboodhka makaanikada ee Shiinaha waxay leeyihiin alaabo kala duwan, agabka ugu muhiimsanna waxaa ka mid ah ABS (terpolymer), PBT (polyterephthalene)
Butylene formate) iyo POM (polyoxymethylene thermoplastic crystalline polymer), oo ay ka mid yihiin ABS iyo PBT alaabta furayaasha ah ayaa inta badan loo adeegsadaa kumbuyuutarrada farsamada ee dhamaadka-sare, iyo walxaha PBT waxay ka fiican yihiin walxaha ABS marka loo eego xirashada caabbinta iyo jilicsanaanta, sidaas darteed qiimaha Caadi ahaan wuu sarreeyaa. marka loo eego walxaha ABS.Shirkadaha furaha furaha ee Shiinaha, kuwa aad loo yaqaan waxaa ka mid ah Amilo, RK, Fuller, Gauss, Thor, iwm
