Ib tus neeg siv khoom tsim lub ntsiab lus - ntawm - qhov chaw muag khoom tuaj rau peb xyoo tas los nrog teeb meem. Lawv tau teev ib lub 6 hli dome ntawm 250g actuation force rau lawv checkout keypad. Tom qab khiav 500,000 lub voj voog ntsuas hauv lawv qhov chaw sim, lub zog tau poob rau 210g. Cov neeg siv khoom xav tias cov domes puas lawm. Lawv tsis yog. Qhov ntawd 16% poob yog ib txwm muaj rau lub dome stainless hlau ntawm ib nrab ntawm ib lab lub voj voog. Qhov yuam kev tiag tiag yog tias tus neeg siv khoom tau teev qhov kev zam nruj ntawm +/- 10g ntawm 250g dome, uas txhais tau hais tias qis dua spec txwv yog 240g. Ntawm 500k cycles, lub dome twb tawm ntawm spec.
Hlau domes poob quab yuam dhau lawv lub neej. Qhov no tsis yog qhov tsis xws luag. Nws yog lub physics ntawm lub caij nplooj ntoos hlav stainless hlau tau flexed lab lub sij hawm. Lo lus nug tsis yog tias kev quab yuam puas, tab sis ntau npaum li cas, thiab seb koj qhov kev kam rau siab tuaj yeem nqus tau li cas.
Kev sim quab yuam kev lwj ntawm 6 hli dome - lub zog ua kom qis qis qis thaum SUS301 ua haujlwm- khov thiab so.
Dab tsi ua rau muaj zog lwj
Lub dome hlau yog tsim los ntawm stainless hlau caij nplooj ntoos hlav. Txhua lub sij hawm nws snaps los ntawm, cov khoom flexes. Tshaj ntau lab lub voj voog, ob yam tshwm sim:
Ua hauj lwm hardening.SUS301 stainless hlau tau nyuaj dua li nws yog flexed, uas hloov nws lub caij nplooj ntoos hlav tas li. Qhov no feem ntau ua rau me me pib quab yuam hauv thawj 10,000 lub voj voog, tom qab ntawd maj mam txo.
Kev ntxhov siab.Cov tsim dome profile maj mam so mus rau ib qho zoo li flatter lub sij hawm thiab cycles. Qhov no yog lub ntsiab ua rau lub sij hawm ntev - quab yuam decay. Nyob rau hauv chav tsev kub, kev ntxhov siab yog qeeb. Thaum kub siab, nws accelerates.
Tus lej quab yuam decay
Raws li peb cov ntaub ntawv xeem ntau lawm ntawm 6mm SUS301 domes ntawm 250g, ntawm no yog qhov koj tuaj yeem xav tau:
| Lub voj voog suav | Lub zog tseem tshuav | Yam lwj |
|---|---|---|
| Pib (0) | 250g | 0% |
| 10,000 | 255g | +2% (ua haujlwm nyuaj) |
| 100,000 | 240g | -4% |
| 500,000 | 220g | -12% |
| 1,000,000 | 200g | -20% |
Cov lej no yog rau chav tsev kub (23C). Ntawm 85C, qhov kev lwj nrawm nrawm mus txog 30% ntawm 1 lab cycles. Ntawm 125C, koj tuaj yeem pom 40% lwj. Qhov no yog vim li cas automotive thiab cov khoom lag luam uas khiav kub xav tau kev ua siab ntev dua los yog lub zog pib dua.
Plaub -legged domes ntawm ib lub reel ntau lawm - ob txhais ceg thauj tog rau nkoj lub dome thiab pab tswj kom muaj zog sib npaug los ntawm ntau lab lub voj voog.
Yuav ua li cas spec ib lub dome uas nyob twj ywm hauv siab ntev
Yog tias koj cov khoom xav tau 1 lab lub voj voog thiab tus neeg siv yuav tsum hnov zoo ib yam nyem, tsis txhob spec qhov pib quab yuam nyob rau hauv qis kawg ntawm koj lub siab ntev band. Spec nws nyob rau sab saum toj kawg nkaus, yog li qhov lwj av nyob rau hauv nruab nrab ntawm koj pawg.
Piv txwv li: koj cov khoom xav tau yam tsawg kawg nkaus 200g quab yuam tom qab 1 lab cycles. Tsis txhob hais txog 200g dome. Specification ntawm 250g dome. Tom qab 20% lwj ntawm 1M cycles, lub zog yuav nyob ib ncig ntawm 200g, uas yog koj qhov tsawg kawg nkaus. Yog tias koj spec ib 220g dome, tom qab 20% lwj koj nyob ntawm 176g, uas yog qis dua koj qhov tsawg kawg nkaus.
Peb hu qhov no lub zog margin. Peb pom zoo kom 15% mus rau 20% quab yuam cov npoo ntawm txhua lub dome uas yuav tsum kav ntev li 1 lab lub voj voog. Ntawm cov khoom siv tsheb uas pom qhov kub siab, peb pom zoo kom 25% npoo.
Dab tsi accelerates lwj
Kub kub siab.Qhov no yog qhov loj tshaj plaws. Lub dome uas poob 20% ntawm chav tsev kub poob 35% ntawm 85C. Yog tias koj cov khoom ua haujlwm kub, spec lub zog pib dua.
Tshaj - mus ncig.Yog tias tus neeg siv nias lub dome dhau los ntawm nws qhov snap point thiab hauv qab tawm ntawm PCB, qhov kev ntxhov siab ntawm cov khoom yog siab dua. Siv lub dome nrog lub siab profile lossis lub spacer kom txwv kev mus ncig.
Tshuaj raug.Cov tshuaj ntxuav thiab cov roj tuaj yeem tawm tsam cov hlau tsis huv, ua kom qaug zog. Rau cov khoom uas tau muab tshem tawm tsis tu ncua, qhia ENIG plating thiab qib stainless uas tiv taus cov tshuaj.
Dome geometry.Hla domes lwj sai dua puag ncig lossis plaub -legged domes, vim tias txhais caj npab flex ntau dua. Yog tias lub neej voj voog ntev yog qhov tseem ceeb, siv ib puag ncig lossis plaub -legged geometry.
Yuav ua li cas peb kuaj kev lwj
Txhua qhov ntau lawm yuav dhau los ntawm kev ntsuas lub voj voog ntawm tus qauv. Peb khiav 10 domes los ntawm txhua lub reel ntawm 60 cycles ib feeb ntawm peb lub voj voog testers, xyuas lub zog ntawm 10k, 100k, 500k, thiab 1 lab cycles. Yog tias lub zog poob ntau dua li peb cov spec (feem ntau 20% ntawm 1M cycles), peb rub ntau thiab tshuaj xyuas cov khoom siv.
Yog koj yogmuas dome sheet arraysrau ib yam khoom uas yuav tsum nyob rau ntau lab lub voj voog, nug peb rau ib daim ntawv ceeb toom quab yuam decay ntawm lub caij nyoog dome koj tab tom xav txog. Peb yuav khiav qhov kev xeem thiab xa koj qhov nkhaus. Rauneeg siv khoom electronics domes, silicone khawmassemblies, lubFPC-raws li dome arrays, hu rau Shanyo engineeringrau kev suav nyiaj margin.
