Tactile hloov yog qhib / tawm hluav taws xob hloov.Tact keyboards yog tactile electromechanical keyboards rau cov keyboards, keypads, instruments lossis interface control-panel applications.Tact keyboards teb rau cov neeg siv kev cuam tshuam nrog lub pob lossis hloov thaum nws ua rau kev sib cuag nrog cov tswj vaj huam sib luag hauv qab.Feem ntau qhov no feem ntau yog cov ntawv luam tawm Circuit Board (PCB).
Feature ntawm tactile keyboards:
・ Kev nyem nyem los ntawm kev tawm tswv yim tactile ・ Tiv thaiv kom tsis txhob muaj qhov tshwm sim los ntawm qhov ntxig-moulded davhlau ya nyob twg ・ Hauv av davhlau ya nyob twg txuas ・ Snap-in mount davhlau ya nyob twg
Kev ceev faj rau kev nyab xeeb Siv lub Hloov nyob rau hauv qhov ntsuas qhov ntsuas hluav taws xob thiab qhov ntsuas tam sim no, txwv tsis pub lub Hloov yuav muaj lub neej luv luv, tawg tshav kub, lossis hlawv tawm.Qhov no tshwj xeeb tshaj yog siv rau cov tam sim no voltages thiab tam sim no thaum hloov.
Kev ceev faj rau kev siv kom raug Kom tiv thaiv kev degradation, xws li tsis muaj xim, nyob rau hauv cov terminals thaum lub sij hawm cia, tsis txhob cia lub Hloov nyob rau hauv cov chaw uas yog raws li nram no tej yam kev mob.1.Kub los yog av noo 2.Corrosive gases 3.Hnub ci ncaj qha
Kev tuav 1.Kev Ua Haujlwm Tsis txhob rov ua haujlwm hloov pauv nrog lub zog ntau dhau.Kev siv ntau dhau los yog siv lub zog ntxiv tom qab lub plunger tau nres tuaj yeem deform lub caij nplooj ntoos hlav ntawm lub Hloov, ua rau muaj kev ua haujlwm tsis zoo.Tshwj xeeb tshaj yog, kev siv lub zog ntau dhau rau Side-operated Switches tuaj yeem ua rau lub qhov cub tawg, uas tuaj yeem ua rau lub Hloov Hloov.Tsis txhob siv quab yuam ntau tshaj qhov siab tshaj plaws (29.4 N rau 1 feeb, ib zaug) thaum txhim kho lossis ua haujlwm Side-operated Switches.Nco ntsoov teem lub Hloov kom lub plunger yuav khiav hauv txoj kab ncaj nraim.Kev txo qis hauv lub neej ntawm Hloov yuav ua rau yog tias lub plunger raug nias tawm ntawm qhov chaw lossis los ntawm lub kaum sab xis.2.Kev tiv thaiv plua plav Tsis txhob siv cov hloov pauv uas tsis raug kaw hauv qhov chaw muaj plua plav.Ua li no yuav ua rau cov plua plav nkag mus rau hauv Hloov Hloov thiab ua rau muaj kev sib cuag tsis raug.Yog tias qhov hloov pauv uas tsis raug kaw yuav tsum tau siv rau hauv ib puag ncig zoo li no, siv daim ntawv lossis lwm yam kev ntsuas los tiv thaiv cov plua plav.
PCBsThe Switch yog tsim los rau 1.6-mm tuab, ib-sab PCB.Siv PCBs nrog ib tug txawv thickness los yog siv ob-sided, los ntawm-lub qhov PCBs tej zaum yuav ua rau xoob mounting, tsis tsim nyog insertion, los yog tsis zoo tshav kub kuj nyob rau hauv soldering.Cov teebmeem no yuav tshwm sim, nyob ntawm seb hom qhov thiab cov qauv ntawm PCB.Yog li ntawd, nws raug pom zoo kom kuaj xyuas qhov tseeb ua ntej siv.Yog tias cov PCBs tau sib cais tom qab txuas lub Hloov, cov khoom ntawm PCBs tuaj yeem nkag mus rau Hloov.Yog hais tias PCB hais los yog txawv teb chaws hais los ntawm ib puag ncig ib puag ncig, workbench, ntim, los yog stacked PCBs ua txuas mus rau lub Hloov, faulty tiv tauj tej zaum yuav tshwm sim.
Soldering 1.Kev ceev faj dav dav ua ntej soldering lub Hloov ntawm ib tug multilayer PCB, sim kom paub meej tias soldering yuav ua tau zoo.Txwv tsis pub lub Hloov yuav raug deformed los ntawm cov cua sov ntawm cov qauv los yog cov av ntawm cov txheej txheem ntau PCB.Tsis txhob solder lub Hloov ntau tshaj ob zaug, nrog rau kev kho kom haum.Ib ncua ntawm tsib feeb yog yuav tsum tau ntawm thawj thiab thib ob soldering.2.Tsis Siv Neeg Soldering BathsSoldering kub: 260 ° C max.Soldering lub sij hawm: 5 s max.rau 1.6-mm tuab ib sab PCBPreheating kub: 100 ° C max.(ambient kub) Preheating lub sij hawm: Tsis pub dhau 60 sNco ntsoov tias tsis muaj flux yuav nce siab tshaj qib ntawm PCB.Yog hais tias fluxoverflows mus rau lub mounting nto ntawm PCB, nws yuav nkag mus rau lub Hloov thiab ua rau ib tug malfunction.3.Reflow Soldering (Nto Mounting) solder lub terminals nyob rau hauv lub cua sov nkhaus qhia nyob rau hauv daim duab nram qab no.Note: Cov saum toj no cua sov nkhaus siv yog hais tias tus PCB thickness yog 1.6 hli.Lub ncov kub yuav txawv nyob ntawm seb lub reflow da dej siv.Paub meej txog cov xwm txheej ua ntej.Tsis txhob siv lub tshuab hluav taws xob tsis siv neeg da dej rau saum npoo-mounted Switches.Cov roj siv hluav taws xob los yog cov khoom siv hluav taws xob tuaj yeem nkag mus rau Hloov thiab ua rau lub Switch's push-button operation.4.Kev ceev Soldering (Tag nrho cov qauv) Soldering kub: 350 ° C max.ntawm qhov kawg ntawm cov hlau soldering lub sij hawm: 3 s max.rau 1.6-mm tuab, ib sab PCBB Ua ntej soldering Hloov ntawm PCB, xyuas kom meej tias tsis muaj qhov tsis tsim nyog ntawm Hloov Hloov thiab PCB.Washing1.Ntxuav tau thiab tsis ntxuav tau ModelStandard Switches tsis kaw, thiab ntxuav tsis tau.Ua li no yuav ua rau tus neeg ua haujlwm ntxhua khaub ncaws, ua ke nrog cov flux lossis hmoov av ntawm PCB, nkag mus rau Hloov, ua rau muaj kev ua haujlwm tsis zoo.2.Kev Siv Lub Tshuab Ntxuav Cov cuab yeej siv ntau tshaj li ib lub da dej tuaj yeem siv los ntxuav cov qauv, yog tias cov qauv ntxuav tau raug ntxuav rau ib feeb siab tshaj plaws hauv ib da dej thiab tag nrho lub sij hawm ntxuav tsis pub dhau peb feeb.3.Ntxuav Cov Tshuaj Siv dej cawv raws li cov kuab tshuaj los ntxuav cov qauv ntxuav.Tsis txhob siv lwm tus neeg ua haujlwm lossis dej los ntxuav cov qauv ntxhua khaub ncaws, vim tias cov neeg ua haujlwm zoo li no tuaj yeem ua rau cov khoom siv lossis kev ua haujlwm ntawm Switch.4.Kev Tiv Thaiv Kev Tiv Thaiv Tsis txhob cuam tshuam lwm yam quab yuam ntawm cov qauv siv thaum ntxuav.Tsis txhob ntxuav cov qauv ntxuav tam sim tom qab soldering.Tus neeg saib xyuas yuav raug nqus mus rau hauv Hloov los ntawm kev ua pa thaum lub Hloov txias.Tos tsawg kawg yog peb feeb tom qab soldering ua ntej ntxuav cov qauv uas ntxuav tau.Tsis txhob siv Sealed Switches thaum submersed hauv dej los yog nyob rau hauv qhov chaw raug dej.Switch ntim
Feem ntau 1000pcs txhua reel raws li hauv qab duab.
