Dab tsi yog qhov zoo tshaj plaws rau sib sau ua ke lub khawm hlau hloov?

Kev sib sau ua ke ahlau khawm hloovMuaj ob peb kauj ruam tseem ceeb los xyuas kom muaj kev ua haujlwm zoo, ua haujlwm ntev, thiab kev nyab xeeb. Hlau khawm keyboards feem ntau siv nyob rau hauv ntau yam kev siv, nrog rau cov khoom siv hluav taws xob, cov khoom siv, thiab cov twj paj nruag zoo li cov khoom siv hluav taws xob. Cov keyboards no nrov rau lawv cov tsos zoo nkauj, tactile tawm tswv yim, thiab kev ua haujlwm ntev. Cov txheej txheem sib dhos tuaj yeem sib txawv nyob ntawm seb hom kev hloov pauv (xws li, ib ntus lossis latching), tab sis cov kauj ruam hauv qab no tuaj yeem coj koj los ntawm cov txheej txheem sib dhos.

1. Nkag siab txog cov kev hloov pauv hloov

Ua ntej pib lub rooj sib txoos, nws yog ib qho tseem ceeb kom nkag siab txog cov lus qhia tshwj xeeb ntawm lub khawm hlau hloov. Cov ntsiab lus tseem ceeb uas yuav tsum xav txog muaj xws li:

Ntaus: Lub sijhawm (thawb kom ua) lossis ua kom nruj (thawb kom toggle).

Voltage thiab Current Ratings: Kom paub meej tias qhov hloov pauv tuaj yeem tswj qhov voltage thiab tam sim no koj lub voj voog yuav xav tau.

Mounting Hom: Vaj huam sib luag mount, PCB mount, los yog nto mount.

Khoom siv: Feem ntau, lub cev ntawm hlau khawm hloov yog tsim los ntawm cov hlau stainless lossis anodized txhuas, ob qho tib si uas siv tau heev.

Loj: Paub meej tias qhov loj ntawm tus hloov mus rau lub mounting qhov lossis pcb tsim.

Teeb pom kev zoo: Qee lub pob hlau khawm hloov ua rau hauv LEDs rau kev pom kev tawm tswv yim thaum qhib.

Kev nkag siab txog cov kev qhia tshwj xeeb no yuav pab koj xaiv cov khoom siv thiab cov cuab yeej kom raug, thiab xyuas kom meej tias qhov hloov pauv ua haujlwm zoo nyob rau hauv qhov txwv ntawm koj tus qauv tsim.

2. Npaj cov cuab yeej thiab cov khoom xyaw

Cov sib dhos ntawm lub khawm hlau hloov yuav tsum muaj qee cov cuab yeej tseem ceeb thiab cov khoom siv:

Soldering hlau thiab solder: Rau kev sib txuas hluav taws xob (yog tias PCB mount lossis hlau txuas yuav tsum tau).

Screwdrivers los yog wrenches: Rau kev nyab xeeb tus hloov mus rau hauv qhov chaw.

Hlau cutters thiab strippers: Los npaj cov xov hlau uas yuav txuas rau tus hloov.

Multimeter: Rau kev sim cov kev sib dhos thiab ua kom sib txuas tau zoo.

Vaj huam sib luag lossis PCB (yog tias tsim nyog): Qhov chaw mounting rau qhov hloov.

Thaum tshav kub kub shrink tubing los yog hluav taws xob daim kab xev: Rau insulating sib txuas.

Mounting kho vajtse: Screws los yog txiv ntseej rau kev ruaj ntseg qhov hloov ntawm qhov chaw.

Thaum koj tau sau cov khoom no, koj tuaj yeem pib txheej txheem sib dhos.

3. Npaj lub Mounting Surface

Txawm hais tias koj tab tom txhim kho qhov hloov mus rau lub vaj huam sib luag lossis PCB, kev npaj yog qhov tseem ceeb rau kev txhim kho kom huv thiab ruaj ntseg.

Vaj huam sib luag Mounting

Rau vaj huam sib luag-Mounted Transveles:

Npaj lub qhov mounting: Siv ib lub laum nrog lub taub me me kom tsim tau ib lub qhov hauv lub vaj huam sib luag uas phim qhov loj ntawm qhov hloov. Xyuas kom tseeb tias lub qhov yog du thiab ua kom zoo sib xws kom yooj yim ntxig ntawm qhov hloov.

Ntxuav qhov chaw: Xyuas kom meej tias thaj chaw ib ncig ntawm lub qhov yog huv thiab tsis muaj cov khib nyiab kom tsis txhob muaj kev cuam tshuam thaum lub teeb nruab.

Ntxig tus hloov: Xaub lub khawm hlau hloov mus rau hauv lub qhov. Yog tias tus hloov pauv muaj cov lus thov tawm, txoj haujlwm nws yog li cov xov seem ntawm cov hloov pauv ntawm cov vaj huam sib luag.

PCB Mounting

Rau PCB-mounted keyboards:

Dlhos tus hloov: Ntxig lub khawm hlau hloov mus los ntawm cov qhov tsim nyog hauv PCB, kom ntseeg tau tias cov kab coj ua kom raug.

Tshawb xyuas qhov kev tshem tawm: Xyuas kom meej tias muaj chaw txaus ib puag ncig tus hloov mus los tiv thaiv ib qho kev sib cuam tshuam nrog nws txoj haujlwm lossis kev txav ntawm tus hloov.

4. Soldering cov kev sib txuas (yog tias muaj)

Yog tias qhov hloov yuav tsum tau sib txuas hluav taws xob (xws li cov qauv PCB-mounted), koj yuav tau siv cov kev coj ua lossis cov kev sib tw mus rau hauv Circuit Court.

Tin cov leads: Ua ntej txuas cov xov hlau los yog cov hlau lead, siv me me ntawm cov solder rau cov lus qhia ntawm cov hlau lead. Qhov no yog hu ua "tinning," thiab nws yuav pab tau lub solder ntws yooj yim dua thaum lub sij hawm soldering txheej txheem.

Npaj cov xaim: Tawm qhov kawg ntawm cov xov hlau uas yuav txuas rau tus hloov. Xyuas kom meej tias cov kab hlau nthuav dav thiab tsis pub dhau ntawm faying.

Solder cov coj mus rau PCB lossis terminals: Thaum tshav kub kub ntawm cov hlau soldering thiab ua tib zoo siv nws mus rau lub solder ncoo ntawm PCB thiab cov hlau lead ntawm qhov hloov. Pub me me ntawm solder rau hauv qhov sib koom ua ke los tsim kev sib txuas ruaj ntseg. Nco ntsoov tsis txhob siv cov solder ntau dhau, vim tias ntau dhau tuaj yeem ua rau luv luv.

Tshawb xyuas cov pob qij zeb yas: Tom qab soldering, tshuaj xyuas tias cov pob qij txha yog du, ci, thiab dawb ntawm cov choj (tsis pub sib txuas nrog cov ntawv sib txuas ntawm cov ntawv uas nyob ib sab). Siv ib qho kev sib txuam los xyuas kom kuaj xyuas txuas ntxiv thiab paub meej tias qhov hloov pauv yog cov xaim kom raug rau hauv Circuit Court.

5. Ruaj ntseg hloov chaw nyob rau hauv qhov chaw

Thaum qhov hloov pauv tau raug teeb tsa thiab cov kev sib txuas hluav taws xob tau ua tiav, cov kauj ruam tom ntej yog txhawm rau txhim kho qhov hloov pauv hauv qhov chaw.

Vaj Huam Sib Luag

Zawm lub txiv ntoo: Yog tias qhov hloov pauv tau tsim los rau kev teeb tsa lub vaj huam sib luag, cov txiv ntoo feem ntau yog muab rau koj siv kom nruj thiab ruaj ntseg hloov mus rau lub vaj huam sib luag. Siv ib tug ciaj ntswj los yog ntswj ntsia hlau los xyuas kom meej tias lub hloov yog nruj nreem kaw, tab sis tsis dhau nruj, uas yuav ua rau cov xov puas.

Kuaj xyuas kom ruaj khov: Maj mam sim qhov hloov los ntawm nias nws kom paub tseeb tias nws tsis txav los yog wiggle. Kev ruaj khov yuav tiv thaiv txhua yam teeb meem hauv lub sijhawm.

PCB Mount

Luag pauv mus hloov nrog cov ntsia hlau (yog tias xav tau): Qee lub PCB-mounted hlau khawm hloov yuav muaj cov screws uas yuav tsum tau ua kom nruj kom ua tau kev sib txuas ruaj khov.

Kom ntseeg tau tias txoj kev kom zoo: Muab ob npaug rau-xyuas qhov kev sib tw ntawm qhov hloov ntawm PCB kom ntseeg tau tias nws raug tso rau kev ua kom muaj zog thiab tsis muaj tus pins lossis cov hlau lead yog khoov lossis puas.

6. Ntsuam xyuas cov kev sib txoos

Thaum lub khawm hlau hloov tau sib sau ua ke, nws yog ib qho tseem ceeb kom sim nws kom paub tseeb tias txhua yam ua haujlwm raws li qhov xav tau.

Tshawb xyuas txuas ntxiv: Siv lub tshuab ntsuas ntau los xyuas seb qhov hloov pauv tau raug kaw lossis qhib lub voj voog thaum nias, nyob ntawm seb nws puas yog lub sijhawm hloov pauv lossis latching hloov.

Ntsuam xyuas cov nuj nqi hauv Circuit Court: Yog tias tus tes hloov yog ib feem ntawm cov kab ke loj dua, lub zog ntawm Circuit Court thiab txheeb xyuas qhov hloov chaw ua haujlwm, txawm hais tias tus ntaus ntawv rau / tawm, hloov cov teeb meem.

Kos lub khawm: Nias lub khawm hlau hloov ob peb zaug kom ntseeg tau tias nws muab cov lus qhia zoo ib yam tactile thiab ua haujlwm zoo. Qhov no yog qhov tseem ceeb rau cov neeg siv kev paub dhau los, tshwj xeeb tshaj yog hauv cov ntawv thov uas yuav tsum muaj kev sib cuam tshuam ntau zaus.

7. Kev hloov kho zaum kawg thiab rwb thaiv tsev

Yog tias tsim nyog, siv cov cua sov shrink tubing los yog hluav taws xob daim kab xev los tiv thaiv cov xov hlau los yog cov pob qij txha. Qhov no yuav pab tiv thaiv cov kev sib txuas los ntawm luv luv Circuit Court thiab ua kom muaj kev nyab xeeb hauv kev sib dhos zaum kawg.

Xaus

Sib sau ua ke lub khawm hlau hloov pauv yuav tsum muaj ob peb kauj ruam tseem ceeb: xaiv txoj cai hloov mus rau txoj haujlwm, npaj lub mounting nto, ua kom ruaj ntseg hluav taws xob sib txuas, thiab kuaj qhov kawg teeb tsa. Los ntawm kev ua raws li cov kauj ruam no ua tib zoo, koj xyuas kom meej tias qhov hloov pauv ua haujlwm tau ntseeg tau, muab cov lus qhia meej meej, thiab tswj xyuas lub sijhawm ntev. Txawm hais tias koj tab tom sib sau cov khawm hlau hloov pauv rau lub tshuab hluav taws xob, lub vaj huam sib luag tswj, lossis daim ntawv thov kev lag luam, siv sijhawm los ua raws li cov txheej txheem sib dhos kom raug yuav ua rau muaj kev hloov pauv tau zoo rau koj qhov project.
