Yuav Ua Li Cas Xaiv Txoj Cai Hlau Dome
Xaiv cov hlau dome kom raug rau koj lub keyboard lossis hloov lub rooj sib txoos yog qhov tseem ceeb rau cov neeg siv kev paub, kev ntseeg tau ntawm cov khoom thiab cov nqi tsim khoom. Nrog kaum ob ntawm cov duab, qhov ntau thiab tsawg, kev ntsuas quab yuam thiab cov ntaub ntawv muaj, cov txheej txheem xaiv tuaj yeem dhau los. Phau ntawv qhia no qhia koj txog tsib qhov kev txiav txim siab tseem ceeb uas koj yuav tsum tau ua thaum qhia lub snap dome.
1. Xaiv qhov Zoo Zoo
| Cov duab | Hom Loj | Zoo tshaj rau |
|---|---|---|
| Round (zeeg) | 4-16 hli | Cov keyboards dav dav, cov chaw taws teeb tswj, lub laij lej - ntau yam |
| Hla / 4- ceg | 5-12 hli | Walkie talkies, khoom siv rugged, siab -tactile xav |
| Daim duab peb sab | 5-15 hli | Cov khoom siv kho mob, kev tswj hwm tsheb, kev ntseeg siab |
| Square / Rectangular | 5-20 hli | Cov yawm sij loj, muaj vaj huam sib luag, VR controllers |
Xauj peb cov ntau yam:puag ncig domes, cross hom domes, daim duab peb sab domesthiabsquare domes.
2. Txiav txim siab lub Actuation Force
Actuation quab yuam yog lub ncov quab yuam uas yuav tsum tau ua rau lub dome lub snap ua. Nws ncaj qha txiav txim siab li cas " khov kho" lossis "lub teeb" tus yuam sij xav tau. Xaiv raws li cov neeg siv pej xeem thiab cov ntaub ntawv siv:
- 100–200g:Lub teeb kov - cov chaw taws teeb tswj, lub tshuab xam zauv, cov khoom siv hluav taws xob
- 200–400g:Nruab nrab - feem ntau keypads, microwave panels, tsheb suab
- 400–800g:Lub tuam txhab - muaj kev tswj hwm, walkie talkies, kev kho mob hnab looj tes
- 800g–3000g:Heavy - cov tshuab hnyav, kev nyab xeeb- khawm tseem ceeb, tiv thaiv- xwm txheej- xovxwm tsim
3. Xaiv cov khoom siv
SUS301 stainless hlauyog tus qauv kev lag luam - zoo heev caij nplooj ntoos hlav zog, corrosion kuj thiab qaug zog lub neej. Nws yog qhov kev xaiv ua ntej rau 90% ntawm daim ntawv thov.Beryllium tooj liab (BeCu)muaj hluav taws xob conductivity ntau dua (tsawg dua kev tiv thaiv) tab sis raug nqi ntau dua thiab qaug zog tsawg dua -resistant. Kub plating muaj nyob rau ntawm cov khoom siv rau corrosion-nruj siab lossis siab- ib puag ncig kev ntseeg tau.
4. Kev kwv yees xav tau lub neej voj voog
Standard SUS301 domes xa 100K-1M actuations. Rau kev kho mob, tsheb lossis cov ntawv thov kev lag luam uas xav tau 1M+ cycles, qhia kub -plated domes lossis siab - qib SUS301 temper. PebRCG series siab -tactile domesraug ntsuas rau 1M + cycles.
5. Dome Sheet Array vs. Individual Domes
Rau cov ntim ntau tshaj 500 units,dome daim ntawv arraystau pom zoo. Ntau lub domes tau ua ntej- txuas rau PET zaj duab xis nrog cov nplaum rov qab, ua kom nrawm nrawm- thiab- qhov chaw sib dhos. Qhov no txo qhov kev tso kawm yuam kev thiab kev sib dhos ua haujlwm los ntawm 70% piv rau tes- tso ib tus neeg domes.
