Network keyboards yog cov caj qaum ntawm cov kev sib txuas lus niaj hnub no, ua kom cov ntaub ntawv tsis sib haum xeeb ntawm cov khoom siv hauv kev lag luam thiab kev lag luam ib puag ncig. Kev tsim khoom ntawm cov khoom tseem ceeb no suav nrog cov txheej txheem nyuaj thiab ua tib zoo sib xyaw ua ke nrog kev siv thev naus laus zis, precision engineering thiab kev tswj xyuas nruj kom xa cov khoom siv txhim khu kev qha, kev ua haujlwm siab. Ntawm no yog tom qab-tus-scenes saib ntawm cov txheej txheem tsim khoom ntawm lub network hloov.
1. Tsim thiab txhim kho
Txoj kev tsim khoom ntawm lub network hloov pauv pib nrog lub sijhawm tsim thiab txhim kho. Engineers thiab designers ua hauj lwm ua ke los tsim cov ncauj lus kom ntxaws specifications thiab blueprints raws li cov kev xav tau ntawm kev ua lag luam, kev vam meej technology thiab cov neeg yuav tsum tau. Cov theem no suav nrog:
Kev tsim Circuit Court: engineers tsim circuits, nrog rau cov ntawv luam tawm Circuit Board (PCB) uas ua haujlwm raws li lub pob txha ntawm qhov hloov.
Cheebtsam xaiv: Xaiv cov khoom zoo, xws li processors, nco chips, thiab cov khoom siv fais fab, uas ua tau raws li cov qauv kev ua tau zoo thiab kev ua haujlwm ntev uas yuav tsum tau muaj rau kev hloov pauv hauv lub network.
Prototyping: Prototypes yog tsim los ntsuas kev ua haujlwm, kev ua tau zoo, thiab kev ntseeg siab ntawm tus qauv tsim. Tus qauv tau dhau los ua qhov kev sim nruj heev txhawm rau txheeb xyuas qhov teeb meem tsim lossis thaj chaw rau kev txhim kho.
2. PCB ntau lawm
Thaum tsim tiav, cov txheej txheem tsim khoom txav mus rau hauv PCB fabrication theem. PCBs yog cov khoom tseem ceeb hauv tsev hluav taws xob hluav taws xob thiab muab cov qauv ntawm lub cev rau kev sib hloov network. Cov txheej txheem ntau lawm suav nrog:
Txheej: Siv ntau txheej ntawm cov tooj liab conductive mus rau qhov tsis yog-conductive substrate tsim hluav taws xob txoj hauv kev txuas ntau yam khoom.
Etching: Tshem tawm cov tooj liab uas tsis tsim nyog los ntawm lub rooj tsavxwm, tawm hauv cov qauv Circuit Court yam xav tau rau kev hloov pauv.
Drilling thiab Plating: Laum qhov rau hauv PCB kom yooj yim tso cov khoom. Cov qhov no yog tom qab ntawd plated nrog cov khoom siv hluav taws xob kom ntseeg tau tias kev sib txuas hluav taws xob zoo.
Daim Ntawv Thov Daim Ntawv Pov Thawj: Siv lub npog ntsej muag tiv thaiv rau PCB txhawm rau tiv thaiv kev luv luv thiab tiv thaiv lub voj voog ntawm ib puag ncig kev puas tsuaj.
Silk Screen Printing: Cov ntawv sau thiab cov cim tau luam tawm ntawm PCB los coj kev sib dhos thiab kev daws teeb meem.
3. Cov khoom sib dhos
Thaum lub PCB npaj txhij, cov kauj ruam tom ntej yog sib sau ua ke rau hauv lub rooj tsavxwm. Cov theem no muaj xws li:
Surface Mount Technology (SMT): Siv cov tshuab tsis siv neeg los tso cov khoom rau ntawm PCB nto nrog qhov tseeb heev. SMT yog txoj kev nyiam rau kev sib txuas me me, cov khoom sib txuas xws li resistors, capacitors, thiab kev sib xyaw ua ke.
Los ntawm-Hole Technology (THT): Rau cov khoom loj dua uas xav tau kev txhawb nqa kev siv tshuab ntxiv, cov khoom siv los ntawm lub qhov tau muab tso rau hauv qhov ua ntej drilled thiab soldered rau PCB.
Reflow soldering: Lub PCB sib sau ua ke dhau los ntawm qhov cub reflow qhov twg cov tshuaj nplaum nplaum melts thiab solidifies, tsim kom muaj kev ruaj ntseg hluav taws xob sib txuas ntawm cov khoom thiab PCB.
4. Firmware programming
Thaum lub cev sib dhos ua tiav, lub network hloov lub firmware yog programmed. Firmware yog software uas tswj kev ua haujlwm thiab kev ua haujlwm ntawm kho vajtse. Cov kauj ruam no suav nrog:
Kev teeb tsa Firmware: Firmware tau teeb tsa rau hauv lub cim xeeb hloov, tso cai rau nws ua cov haujlwm yooj yim xws li pob ntawv hloov pauv, routing, thiab kev tswj hwm network.
Kev Ntsuas thiab Calibration: Cov kev hloov pauv tau sim los xyuas kom meej tias lub firmware raug teeb tsa kom raug thiab txhua txoj haujlwm tau ua haujlwm raws li qhov xav tau. Cov kauj ruam no tuaj yeem suav nrog kev ntsuas kev ntxhov siab txhawm rau txheeb xyuas qhov kev hloov pauv kev ua haujlwm raws li qhov sib txawv ntawm lub network loads.
5. Kev Tswj Xyuas Zoo thiab Kev Xeem
Kev tswj xyuas zoo yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom, ua kom txhua lub network hloov tau raws li cov qauv siab tshaj plaws ntawm kev ua tau zoo, kev ntseeg tau thiab kev ruaj ntseg. Cov theem no muaj xws li:
Kev Ntsuas Kev Ua Haujlwm: Txhua qhov kev hloov pauv tau kuaj xyuas kom ntseeg tau tias nws ua haujlwm zoo thiab txhua qhov chaw nres nkoj thiab cov yam ntxwv ua haujlwm raws li qhov xav tau.
Kev ntsuam xyuas ib puag ncig: Cov kev hloov pauv tau sim rau qhov kub, av noo, thiab kev co kom ntseeg tau tias lawv tuaj yeem tiv taus ntau qhov chaw ua haujlwm.
Kev Ntsuas EMI / EMC: Kev ntsuas hluav taws xob cuam tshuam (EMI) thiab electromagnetic compatibility (EMC) yog ua los xyuas kom meej tias qhov hloov pauv tsis muaj teeb meem hluav taws xob thiab tuaj yeem ua haujlwm nrog lwm yam khoom siv hluav taws xob yam tsis muaj kev cuam tshuam.
Kev ntsuas kub hnyiab: Lub tshuab hluav taws xob tau qhib thiab khiav mus rau lub sijhawm txuas ntxiv txhawm rau txheeb xyuas qhov muaj feem cuam tshuam lossis ua tsis tiav uas yuav tshwm sim dhau sijhawm.
6. Kev sib dhos zaum kawg thiab ntim khoom
Tom qab dhau tag nrho cov kev ntsuam xyuas zoo, lub network hloov nkag mus rau qhov kawg sib dhos thiab ntim cov theem. Qhov no suav nrog:
Enclosure Assembly: Lub PCB thiab cov khoom siv tau muab tso rau hauv lub thawv ruaj ruaj tsim los tiv thaiv qhov hloov ntawm lub cev puas tsuaj thiab ib puag ncig.
Labeling: Txhua qhov hloov pauv tau sau nrog cov ntaub ntawv khoom, tus lej xov tooj, thiab cov cim kev ua raws cai.
Ntim: Cov hloov pauv tau ua tib zoo ntim los muab kev tiv thaiv thaum thauj thiab khaws cia. Lub pob kuj tseem tuaj yeem suav nrog phau ntawv siv, lub zog hluav taws xob, thiab lwm yam khoom siv ntxiv.
7. Kev xa khoom thiab kev xa tawm
Thaum ntim khoom, lub network hloov pauv tau npaj rau kev xa khoom thiab xa tawm. Lawv raug xa mus rau warehouses, distributors lossis ncaj qha rau cov neeg siv khoom thoob ntiaj teb. Pab neeg logistics xyuas kom meej tias cov keyboards raug xa mus zoo, raws sijhawm, thiab npaj rau kev xa mus rau ntau qhov chaw hauv network.
nyob rau hauv xaus
Kev tsim cov tshuab hluav taws xob network yog cov txheej txheem nyuaj uas ua ke nrog cov thev naus laus zis siab, kev ua haujlwm zoo thiab kev ruaj ntseg zoo. Txhua kauj ruam los ntawm kev tsim thiab PCB kev tsim khoom mus rau kev sib dhos, kev sim thiab ntim khoom yog qhov tseem ceeb rau kev xa cov khoom uas ua tau raws li qhov xav tau siab ntawm niaj hnub network infrastructure. Raws li lub caj qaum ntawm kev sib txuas lus niaj hnub no, cov keyboards no ua lub luag haujlwm tseem ceeb hauv kev ua kom ntseeg tau cov ntaub ntawv muaj txiaj ntsig zoo thoob plaws hauv kev lag luam thiab kev siv.
