I. Xaiv Koj Tus Neeg Muag Khoom Zoo
Thaum yuav cov khoom siv hluav taws xob, cov neeg siv khoom yuav tsum tsis txhob raug swayed los ntawm tus nqi qis. Nws yog qhov zoo tshaj plaws los ua kev yuav khoom ntawm lub npe nrov, loj -cov khw muag khoom loj, khw muag khoom loj, lossis cov khw muag khoom siv hluav taws xob, thiab khaws koj cov ntaub ntawv pov thawj ntawm kev yuav khoom.
II. Tshawb xyuas qhov tshwm sim
Cov style thiab xim ntawm cov keyboards yuav tsum sib haum nrog tag nrho sab hauv tsim ntawm chav tsev. Piv txwv li, yog tias cov xim tseem ceeb ntawm cov décor sab hauv yog lub teeb -toned, ib tus yuav tsum tsis txhob xaiv cov keyboards hauv cov xim tsaus nti xws li dub lossis xim av. Tsis tas li ntawd, qhov ntim ntawm cov khoom ua raws li cov khoom siv yuav ua kom tiav cov chaw tsim khoom thiab cov ntaub ntawv khoom; conversely, lub ntim ntawm substandard sockets feem ntau flimsy thiab tsis muaj cov ntsiab lus tseem ceeb -tshwj xeeb tshaj yog hnub tsim. Ntau cov khoom lag luam tsis zoo tsis tuaj yeem tso tawm hnub tsim khoom ntawm lawv lub ntim, uas yog qhov qhia tau zoo ntawm cov khoom tsis raug cai -. Tsis tas li ntawd, lub ntsej muag lub ntsej muag ntawm siab - cov qhov (sockets) zoo muaj cov khoom siv tes ua haujlwm zoo, tsis muaj burrs lossis cov npoo ntxhib nyob ib ncig ntawm lub qhov rooj lossis lub qhov (socket) qhib; qhov ntev ntawm lub qhov (socket) yog symmetrical thiab uniform. Hauv qhov sib piv, cov casings ntawm cov neeg tsis zoo - cov qhov (socket) zoo feem ntau qhia txog kev ua haujlwm hnyav.
III. Ntsuam xyuas Tactile Quality
Koj tuaj yeem ntsuas qhov zoo ntawm lub qhov (socket) los ntawm plaub qhov kev ntsuas tactile tseem ceeb: ntsuas nws qhov hnyav, rov ua dua qhov hloov pauv, ntsuas qhov ntxig thiab tshem tawm quab yuam, thiab rub lub zog qaum.
1. Ntsuam xyuas qhov hnyav: Cov qhov (socket) uas ua tau raws li lub teb chaws cov qauv muaj ntau dua ntawm cov xov tooj tooj liab thiab cov tooj liab tuab dua nyob rau hauv, thiab muaj cov yas yas ruaj khov; yog li ntawd, lawv xav tias hnyav heev. Substandard sockets, tau tsim los ntawm cov khoom siv tsis zoo thiab cov shortcuts, yuav hnov qhov sib dua.
2. Toggle lub Hloov: Rov qab nias lub qhov (socket) lub hwj chim hloov ob peb zaug. Lub qhov (socket) ua raws li yuav hloov tau yooj yim thiab tsis muaj zog, nrog rau lub suab sib txawv, sib txawv nias. Lub qhov (socket) tsis zoo, txawm li cas los xij, yuav hnov nkig los yog nruj rau qhov kov thiab nws yooj yim rau lo los yog jamming.
3. Test Insertion/Extraction Force: Nyob rau hauv lub qhov (socket) ua raws, lub zog yuav tsum tau ntxig thiab rho tawm ib lub ntsaws los ntawm txhua tus neeg lub qhov (socket) qhib yuav tsum hnov mob thiab springy; Tsis tas li ntawd, qhov kev xav tactile yuav tsum zoo ib yam thoob plaws txhua qhov qhib. Cov qhov (sockets) feem ntau xav tias xoob dhau los yog nruj dhau; lawv tsis muaj lub caij nplooj ntoos hlav zoo, nws yuav ua rau xoob dhau lub sijhawm, thiab qhov kev xav tactile tuaj yeem sib txawv ntawm ib lub qhov (socket) qhib mus rau lwm qhov.
4. Rub lub hwj chim qaum: Lub hwj chim qaum ntawm lub qhov (socket) ua raws li yuav tsum xav tias tsis yog mos heev los yog nruj heev rau qhov kov, thiab nws txoj kev sib txuas rau lub qhov (socket unit) yuav tsum ruaj thiab ruaj ntseg. Piv txwv li, lub hwj chim qaum ntawm lub qhov (socket) tsis zoo feem ntau hnov mob heev thiab txuas nrog tsis muaj kev ruaj ntseg rau chav tsev, ua rau nws yooj yim rub tawm los yog tshem tawm.
IV. Ua ntej Brand Reputation
Cov neeg siv khoom tau txais kev txhawb siab los xaiv cov khoom lag luam los ntawm cov khoom lag luam zoo - paub thiab muaj npe nrov. Qhov no yog vim qhov zoo ntawm cov hluav taws xob hloov hluav taws xob thiab cov qhov hluav taws xob cuam tshuam ncaj qha rau kev nyab xeeb thiab kev ua haujlwm zoo ntawm koj cov khoom siv - thiab, qhov tseeb, tag nrho qhov yooj yim thiab kev nplij siab ntawm koj lub neej txhua hnub. Hauv kev xam phaj, ntau tus neeg xa khoom tau qhia txog kev sib koom ua ke: cov keyboards thiab lub qhov (sockets) tsim los ntawm ntau tus me me - nplai cov tuam txhab lag luam tsis ntseeg siab thiab muaj lub neej ua haujlwm luv luv. Yog li ntawd, qhov kev xav tau ntau zaus rau kev hloov pauv ua pov thawj yog qhov tsis yooj yim.
V. Xav txog tom qab-Kev Pabcuam Muag
Thaum twg los tau, yuav los ntawm cov khw muag khoom tshwj xeeb lossis cov chaw muag khoom tau tso cai los ntawm cov tuam txhab muaj npe nrov, thiab nco ntsoov thov daim ntawv them nqi muag khoom. Qhov no ua kom ntseeg tau tias koj tuaj yeem nkag mus rau qhov tsim nyog tom qab - kev txhawb nqa muag yav tom ntej.
VI. Txheeb xyuas cov cim
Ua tib zoo saib xyuas cov cim uas nyob rau ntawm lub hauv paus ntawm cov keyboards thiab qhov (sockets); cov no yuav tsum suav nrog "Great Wall Certification" (CCEE) cim, nrog rau cov ntsuas tam sim no thiab qhov ntsuas hluav taws xob.
VII. Tshawb xyuas kev ua raws li cov qauv
Xaiv cov khoom tsim raws li GB2099.3-2008 tus qauv. Thaum Lub Rau Hli 1, 2010, cov tub ceev xwm hauv lub tebchaws tau tshaj tawm cov qauv tshiab hauv tebchaws, uas tom qab ntawd tau dhau los ua qhov yuav tsum tau ua. Cov txheej txheem no txwv tsis pub tsim cov "universal sockets" (cov tsim los txais ntau hom ntsaws). Tus txheej txheem tshiab tso cai rau kev tsim cov qhov (socket) uas muaj kev sib cais - qhov twg ob - tus pin thiab peb - tus pin sockets raug cais (feem ntau hu ua "tshiab tsib lub qhov (socket)"). Qhov kev tsim no ua rau kom muaj kev sib cuag ntawm qhov chaw nruab nrab ntawm lub ntsaws thiab lub qhov (socket), kom muaj kev sib txuas nruj dua thiab yog li txo qhov kev pheej hmoo ntawm hluav taws xob poob siab.
