Yog tias koj tau ntaus lub tshuab ntaus ntawv, nias lub pob microwave, lossis kos npe rau ntawm POS davhlau ya nyob twg, koj tau siv lub dome hlau hloov. Tom qab qhov txaus siab "nias" yog ib qho kev ua tiav tiav ntawm lub caij nplooj ntoos hlav stainless hlau uas tawg nyob rau hauv quab yuam thiab rov ua haujlwm. Txawm li cas los xij, rau cov kws tshaj lij hais txog cov khoom no, cov ntaub ntawv xov tooj - kev khiav hauj lwm quab yuam, mus ncig, snap piv, kam rau ua - tuaj yeem tsis meej pem. Phau ntawv qhia no piav qhia tias txhua qhov ntsuas txhais tau li cas hauv kev xyaum, thiab yuav ua li cas kom phim lub dome rau koj daim ntawv thov.
Dab tsi yog Hlau Dome Hloov?
Hlau dome hloov (tseem hu ua asnap dome) yog ib qho ntiav, concave disc ua los ntawm lub caij nplooj ntoos hlav steel - yuav luag txhua lub sij hawm SUS301 ib nrab-cov hlau tsis muaj zog rau cov ntawv thov keypad. Thaum koj nias qhov chaw, lub dome inverts nrog ib tug nkig snap thiab hu rau ib tug luam Circuit Court board kab hauv qab no, kaw lub Circuit Court. Tso nws, thiab lub caij nplooj ntoos hlav quab yuam pops nws rov qab. Tag nrho cov txheej txheem yog txhua yam, uas yog vim li cas domes muaj sia nyob ntau lab ntawm kev ua haujlwm yam tsis muaj hnav- tawm ntawm kev sib cuag nws tus kheej.
Domes tuaj nyob rau hauv puag ncig, plaub- ceg ntoo khaub lig, daim duab peb sab thiab duab plaub. Feem ntau yog lub voj voog dome - 6mm, 8.4mm, 12mm thiab 20mm diameters npog feem ntau ntawm cov neeg siv khoom, kev lag luam thiab kev kho mob keypads.
Nyeem Lub Zog-Txoj Kev Hloov Pauv
Txhua lub dome muaj lub zog- txav nkhaus - ib daim duab qhia tias koj siv zog npaum li cas rau qhov deb ntawm lub dome deflects. Nkag siab qhov nkhaus no yog ib qho txuj ci tseem ceeb tshaj plaws thaum xaiv lub dome. Peb tus lej txhais nws:
- Lub zog ua haujlwm (Fo):Lub zog ncov ua ntej lub dome snaps. Qhov no yog qhov koj tus ntiv tes zoo li tsis kam. Cov txiaj ntsig zoo li ntawm 180g (lub teeb kov, cov neeg siv khoom siv) mus txog 500g (kev lag luam keypants, hnab looj tes ua haujlwm).
- Tiv tauj quab yuam (Fc):Lub zog nyob rau hauv qab ntawm lub snap, thaum lub dome yog tag nrho inverted thiab kov lub PCB. Qhov no qis dua Fo - qhov sib txawv tsim qhov "nias" hnov.
- Taug kev deb:Qhov chaw nyob deb npaum li cas los ntawm kev so kom tawg tag. Round domes feem ntau mus ncig 0.25-0.6mm. Kev taug kev luv luv zoo li nkig thiab lub teeb; ntev mus ncig xav tias txhob txwm.
Qhov piv ntawm (Fo − Fc) / Fo yog hu uasnap piv. Lub siab snap piv (40–60%) muab lub suab nrov, tactile nyem - zoo rau kev siv tshuab thiab sab nraum zoov keypads uas koj xav tau kev pom zoo. Qhov qis snap piv (20–30%) xav tias nyob ntsiag to thiab du - nyiam rau cov khoom siv kho mob thiab chaw ua haujlwm ntsiag to.
Vim li cas SUS301 Stainless Hlau?
Zoo tag nrho cov qauv domes siv SUS301 (AISI 301) ib nrab -lub caij nplooj ntoos hlav tawv stainless hlau. Cov hlau sib xyaw ua ke ntawm lub zog tensile siab (~ 1,500 MPa), zoo corrosion kuj thiab lub caij nplooj ntoos hlav zoo ib yam tom qab rov ua dua tshiab ua rau nws zoo tagnrho. Domes yog tsim los ntawm precision stamping thiab kev ntxhov siab-relieved kom stabilize tus cwj pwm quab yuam nyob rau hauv qhov kub thiab txias thiab lub neej voj voog.
Rau qhov xav tau ib puag ncig, domes tuaj yeem ua taukub -platedlos yog npib tsib xee-plated los txo kev tiv thaiv thiab txhim kho corrosion kuj. Kub plating yog muaj nyob rau hauv kev kho mob thiab siab - daim ntawv thov kev cia siab rau qhov kev sib cuag ruaj khov tshaj 10+ xyoo yuav tsum tau. CovC-series round domeslos ntawm SUNAURA, piv txwv li, muaj nyob nrog kev xaiv kub flash plating ntawm qhov chaw tiv tauj.
Xaiv Txoj Cai Dome rau Koj Daim Ntawv Thov
Cov khoom siv hluav taws xob siv hluav taws xob (cov chaw taws teeb tswj, TV, teeb- cov thawv sab saum toj):Lub teeb ua hauj lwm quab yuam (180-250g), txoj kab uas hla me me (6-8.4mm), qis snap piv. Tus nqi-sensitive; txheem unplated SUS301 yog txaus. Saib pebchaw taws teeb tswj dome arrays.
Industrial HMI thiab machinery panels:Nruab nrab quab yuam (300-400g), nruab nrab snap piv rau lub suab tawm tswv yim. Domes yuav tsum muaj sia nyob 1-5 lab kev ua haujlwm thiab zam qhov kub thiab txias. Xav txogindustrial dome txheejnrog ESD shielding.
Cov cuab yeej kho mob:Lub zog sib xws (± 15g kam rau ua), cov ntaub ntawv biocompatible, huv -chav sib dhos.Kev kho mob- qib domesfeem ntau tuaj nrog kub plating thiab tag nrho traceability. Ua ke nrogCov khoom siv kho mob vaj huam sib luag PCBkev daws teeb meem rau kev sib koom ua ke.
Automotive sab hauv keyboards:Kub siab kam rau ua (-40℃rau 85 degree), kev co kuj, 10-xyoo durability.Tsheb dome arrayssiv cov nplaum tshwj xeeb thiab tuav cov qauv tsim los tiv thaiv dome tsiv teb tsaws hauv qab vibration.
Feem ntau yuam kev hauv kev xaiv Dome
Tom qab ntau xyoo ntawm kev ua hauj lwm nrog OEM engineering pab pawg, peb pom tib pitfalls dua:
- Xaiv los ntawm qhov loj me xwb.Ob lub 8.4mm domes tuaj yeem xav tias txawv kiag li nyob ntawm cov khoom siv temper thiab snap piv. Ib txwm thov kom muaj zog nkhaus, tsis yog ib daim ntawv loj loj.
- Ignoring kam rau ua.Lub dome ntsuas ntawm 300g ± 50g txhais tau hais tias lub zog tiag tiag txawv ntawm 250g mus rau 350g thoob plaws ntau lawm. Rau kev xav zoo ib yam hauv cov neeg siv khoom, qhia meej ± 15g kam rau ua.
- Overlooking kub.Lub caij nplooj ntoos hlav quab yuam poob ntawm qhov kub thiab txias. Lub dome uas xav tias zoo ntawm 25℃yuav hnov mob ntawm 85 degree. Rau kev siv tsheb thiab kev lag luam, txheeb xyuas qhov quab yuam ntawm koj qhov kev ua haujlwm siab tshaj plaws.
- Qhia plating yam tsis muaj laj thawj.Kub plating ntxiv tus nqi. Tsuas yog qhia nws yog tias koj xav tau kev tiv thaiv qis, ntev - lub sij hawm corrosion tsis kam, lossis kev kho mob - qib kev ntseeg tau.
Pairing Domes nrog txoj cai substrate
Lub dome tsis ua haujlwm hauv kev sib cais. Nws zaum ntawm ibdome daim ntawv arraynrog PET lossis polyimide cab kuj, nplaum txheej thiab qee zaum FPC connector. Lub substrate thickness, hom nplaum thiab tuav lub nplhaib tsim txhua yam cuam tshuam rau qhov kawg xav. Rau siab - cov khoom ntim, peb pom zoo kom ua qauv nrog 2-3 dome xaiv ntawm koj lub substrate tiag tiag ua ntej xauv hauv qhov tsim.
Rau kev ua kom tiav keypad sib dhos,kev cai membrane keyboardsintegrate domes, overlay graphics, LED backlighting thiab connectors rau hauv ib qho subassembly, txo cov nqi sib dhos thiab txhim kho qhov sib xws.
Tau Txais Txoj Cai Dome rau Koj Tsim
SUNAURA tsim cov puag ncig, hla, daim duab peb sab thiab cov duab plaub domes los ntawm SUS301 stainless hlau, muaj nyob rau hauv ib tus neeg domes lossis ua ntej- sib dhos dome daim ntawv arrays. Peb muab cov qauv dawb, quab yuam cov ntaub ntawv nkhaus thiab kev txhawb nqa engineering rau kev cai layouts. Hu rau peb pab pawg Qingdao engineering nrog koj lub zog ua haujlwm, kev mus ncig thiab lub neej- lub voj voog yuav tsum, thiab peb yuav pom zoo lub dome zoo tshaj plaws rau koj daim ntawv thov.
Hais txog SUNAURA (Shanyo Precision Electronics):Raws li nyob rau hauv Qingdao, Tuam Tshoj, SUNAURA yog IATF 16949 thiab ISO 13485 certified chaw tsim tshuaj paus ntawm hlau domes, dome arrays, FPC circuits, silicone keypads thiab membrane keyboards pab kho mob, tsheb, industrial thiab neeg siv khoom electronics OEMs thoob ntiaj teb.
