Membrane switches: chaiyo yekudzora chishandiso chemidziyo yemagetsi
Membrane switches ndiwo chaiwo ekudzora zvikamu anoshandiswa zvakanyanya mumidziyo yemagetsi.Iwo akanyatsobatanidzwa nePCB maseketi kuti ape anoshanda uye akavimbika emushandisi madhiraivha uye mashandiro ekutonga kwemidziyo yemagetsi.
Iyo yakakosha tekinoroji inoshandiswa mu membrane switch ndeye nhete-firimu redunhu kudhinda.Iwo akagadzirwa neakatetepa firimu zvinhu ane conductive mitsara uye nzvimbo dzakakosha dzakadhindwa pairi.Kana kiyi pa membrane switch inodzvanywa, mitsetse inovhara inovhara, ichizadza kubatanidza kwedunhu.Iyi dhizaini inopa iyo membrane switch yakanakisa kunzwa uye nemazvo.
Imwe mukana we membrane switch ndeye kuvakwa kwavo kuri nyore.Iwo anongosanganisira imwe chete layer yeyakaonda firimu zvinhu, zvichiita kuti ive idiki uye ikareruka pane yechinyakare mechanicha switch.Izvi zvinovaita kuti vakwane zvirinani kune compact dhizaini zvinodiwa zvemagetsi zvishandiso.Membrane switches zvakare ine hupenyu hurefu hwesevhisi uye inokwanisa kushingirira ma-high-frequency pressing operations.
Kuvimbika kwe membrane switch ndicho chimwe chikonzero chekuzivikanwa kwavo.Sezvo ivo vachigadzirwa vachishandisa nzira yekudhinda, iyo chaiyo yekugadzira mitsetse ye conductive inogona kudzorwa nemazvo, ichidzikisa kutadza mwero.Pamusoro pezvo, kuchinjika kwemhando yefirimu inoita kuti isanyanya kuvhunduka uye kudedera, ichiibvumira kushanda zvakatsiga munzvimbo dzekushanda dzakaoma.
Uyezve, membrane switch inogoneka.Vagadziri vanogona kugadzira uye kuagadzirisa mumhando dzakasiyana uye saizi kuti asangane nezvinodiwa zvekushanda.Uku kuchinjika kunoita kuti membrane switch ive chinhu chakakosha mukugadzira zvigadzirwa zvemagetsi.
Muchidimbu, membrane switch inoita basa rakakosha mumidziyo yemagetsi.Iwo akanyatsobatanidzwa nePCB maseketi kuti ape anoshanda uye akavimbika emushandisi madhiraivha uye mashandiro ekutonga kwemidziyo yemagetsi.Chimiro chakareruka, kuvimbika kwepamusoro, kunzwisiswa kwakanyanya, uye kurongeka kwemembrane switch inoita kuti ive chinhu chakakosha chekudzora chishandiso mukugadzira zvigadzirwa zvemagetsi zvemazuva ano.
Iyo yakajairwa chimiro che membrane switch inowanzo sanganisira zvinotevera zvikamu zvikuru:
1. Graphic Overlay: Chikamu chikuru chemembrane switch inogadzirwa nedhizaini ye graphic overlay, kazhinji firimu repolyester kana firimu repolycarbonate.Iyi firimu zvinhu inochinjika uye yakasimba, inokodzera kiyi yekushanda.
2. Overlay Adhesive: The overlay adhesive ye membrane switch inoshandiswa kuenderana ne shrapnel layer uye film panel layer mu membrane switch.Inonamirwa pane graphic overlay layer uye inodzivirira nzvimbo yemakiyi nemahwindo.
3. Dome retainer: Ichi chikamu che membrane switch chinoshandiswa kubata simbi domes (inozivikanwawo sechitubu tab kana chitubu chekubata tab).Iyo metal dome ndechimwe chezvinhu zvakakosha zve membrane switch.Iyo elastic zvekuti kana kiyi ikadzvanywa, inokotama uye inosangana neiyo conductive layer kuti iwane kuvharwa kwedunhu.Basa rekuchengetedza layer nderekugadzirisa simbi dome munzvimbo chaiyo kuti ive nechokwadi chekuti inoshanda nemazvo kana kiyi ichidzvanywa.
4. Spacer adhesive: The spacer adhesive, inozivikanwawo se spacer adhesive, is spacer layer inoshandiswa mu membrane switch ine adhesive kumativi ose maviri.Basa rayo guru nderekugadzira spacer pakati peiyo dome retainer uye cirucit layer ye membrane switch uye inopa kudzvanywa kwakaringana uye chinhambwe kuti uve nechokwadi chekushanda kwakakodzera kwekuchinja.Iyo spacer ye membrane switch inowanzo gadzirwa neakakosha adhesive zvinhu, senge polyester firimu kana polyether firimu.Izvi zvinhu zvine zvakanaka zvekunamira zvimiro uye zvakavimbika zvinosunga iyo conductive layer kune substrate panguva yekusangana kwe membrane switch.
5. Circuit layer: Masekete ekuitisa anoumbwa pane iyo firimu zvinhu kuburikidza nemaitiro akadai sekudhinda kana etching.Conductive sirivheri paste kana conductive kabhoni inki ndiyo inowanzoshandiswa zvinhu zvemaseketi aya.Izvi zvinoitisa zvinhu zvinobvumira iyo membrane switch kuti iwane kuvharika kwekuita panguva yekushanda kwakakosha.
6. Rear adhesive: Ndiyo inonamatira kana glue layer inoshandiswa kumashure kwe membrane switch.Icho chinhu chakakosha mukuchengetedza membrane switch kune substrate kana chimwe chishandiso chayakaiswa.Iyo inowanzo kuwanikwa kuseri kwe membrane switch kuti ive nechokwadi chekugadzikana uye kuchengetedzeka panguva yekushandiswa.
