Ukutshintsha kweMembrane: isixhobo solawulo oluchanekileyo kwizixhobo zombane
Ukutshintsha kweMembrane ngamacandelo olawulo oluchanekileyo asetyenziswa kakhulu kwizixhobo zombane.Zidityaniswe ngokuqinileyo kunye neesekethe zePCB ukubonelela ngojongano lomsebenzisi olusebenzayo noluthembekileyo kunye nolawulo lokusebenza lwezixhobo zombane.
Itekhnoloji engundoqo esetyenziswa kwi-membrane switch is thin-film yesekethe yoshicilelo.Zenziwe ngoluhlu lwezinto ezincinci zefilimu ezinemizila eqhubayo kunye neendawo eziphambili eziprintiweyo kuyo.Xa isitshixo kwi-membrane switch sicinezelwe, imigca ye-conductive ivala, igqibezela uxhulumaniso lwesiphaluka.Olu yilo lunika i-membrane switch ebalaseleyo ubuntununtunu kunye nokuchaneka.
Enye inzuzo yokutshintsha kwe-membrane kukwakhiwa kwabo okulula.Ziquka kuphela umaleko omnye wezinto zefilimu ezibhityileyo, ezizenza zibencinci kwaye zibe khaphukhaphu kunokutshintsha koomatshini bemveli.Oku kubenza bafaneleke ngcono kwiimfuno zoyilo oludibeneyo lwezixhobo zombane.Ukutshintsha kweMembrane nako kunobomi benkonzo ende kwaye inokumelana nokusebenza koxinzelelo oluphezulu.
Ukuthembeka kokutshintsha kwe-membrane sesinye isizathu sokuthandwa kwabo.Ekubeni ziveliswa ngokusebenzisa inkqubo yokushicilela, ukuchaneka kokuveliswa kwemigca ye-conductive inokulawulwa ngokuchanekileyo, ukunciphisa izinga lokungaphumeleli.Ukongeza, indalo eguquguqukayo yemathiriyeli yefilimu iyenza ixhathise kakhulu ukothuka kunye nokungcangcazela, ukuyivumela ukuba isebenze ngokuzinzileyo kwiindawo zokusebenza ezinzima.
Ngapha koko, iiswitshi ze-membrane ziyakwazi ukwenzeka.Abavelisi banokuyila kwaye bayenze ngokwemilo eyahlukeneyo kunye nobukhulu ukuhlangabezana neemfuno ezithile zokusebenza.Oku bhetyebhetye kwenza iiswitshi ze-membrane zibe licandelo eliphambili ekwenzeni izixhobo zombane.
Isishwankathelo, ukutshintshwa kwe-membrane kudlala indima ebalulekileyo kwisixhobo sombane.Zidityaniswe ngokuqinileyo kunye neesekethe zePCB ukubonelela ngojongano lomsebenzisi olusebenzayo noluthembekileyo kunye nolawulo lokusebenza lwezixhobo zombane.Ulwakhiwo olulula, ukuthembeka okuphezulu, ubuntununtunu obugqwesileyo, kunye nokuchaneka kokutshintsha kwe-membrane kubenza babe sisixhobo solawulo oluchanekileyo xa kusenziwa izixhobo zombane zanamhlanje.
Ubume besiqhelo bokutshintsha kwenwebu budla ngokubandakanya ezi nxalenye zilandelayo:
1. I-Graphic Overlay: Inxalenye ephambili yokutshintsha kwe-membrane yenziwe ngumaleko we-graphic overlay, ngokuqhelekileyo ifilimu ye-polyester okanye ifilimu ye-polycarbonate.Esi sixhobo sefilimu siguquguqukayo kwaye sihlala sihlala, sifanelekile ekusebenzeni okubalulekileyo.
2. I-Adhesive ye-Overlay Adhesive: I-adhesive yokugqithisa i-membrane switch isetyenziselwa ukulungelelanisa umgca we-shrapnel kunye noluhlu lwepaneli yefilimu kwi-membrane switch.Incanyathiselwe kumaleko wokwaleka kwegraphic kwaye inqanda indawo yezitshixo kunye neefestile.
3. I-Dome retainer: Le yinxalenye yokutshintsha kwe-membrane esetyenziselwa ukubamba i-metal domes (eyaziwa ngokuba yi-spring tab okanye i-spring contact tab).Idome yentsimbi yenye yezinto eziphambili zokutshintsha kwenwebu.I-elastic ukwenzela ukuba xa isitshixo sicinezelwe, siyagoba kwaye sidibana ne-conductive layer ukufezekisa ukuvalwa kwesekethe.Umsebenzi we-retainer layer kukulungisa idome yensimbi kwindawo echanekileyo yokuqinisekisa ukuba isebenza ngokufanelekileyo xa isitshixo sicinezelwe.
4. I-Spacer adhesive: I-adhesive spacer, eyaziwa ngokuba yi-spacer adhesive, i-spacer layer esetyenziswe kwi-membrane switch kunye ne-adhesive kumacala omabini.Umsebenzi wayo oyintloko kukwenza i-spacer phakathi kwe-dome retainer kunye ne-cirucit layer ye-membrane switch kunye nokubonelela ngoxinzelelo olufanelekileyo kunye nomgama wokuqinisekisa ukusebenza ngokufanelekileyo kokutshintsha.I-spacer yokutshintsha kwe-membrane ngokuqhelekileyo yenziwe ngezinto ezinamathele ezikhethekileyo, ezifana nefilimu ye-polyester okanye ifilimu ye-polyether.Ezi zixhobo zineempawu ezintle zokubambelela kwaye zibophe ngokuthembekileyo umaleko wokuqhuba kwi-substrate ngexesha lokudibanisa i-membrane switch.
5. Umaleko weSekethe: Iisekethe eziqhubayo zenziwe kwizinto zefilimu ngokusebenzisa iinkqubo ezinjengokushicilela okanye etching.I-conductive paste yesilivere okanye i-inki ye-carbon conductive zizinto eziqhelekileyo ezisetyenziselwa ezi ziphakethi.Ezi zixhobo zokuqhuba zivumela ukuba i-membrane itshintshe ukuphumeza ukuvalwa kwe-conductive ngexesha lomsebenzi obalulekileyo.
6. I-adhesive ngasemva: I-adhesive okanye i-glue layer isetyenziswe ngasemva kwe-membrane switch.Iyinxalenye ephambili ekukhuseleni ukutshintshela kwe-membrane kwi-substrate okanye esinye isixhobo apho ifakwe khona.Ngokuqhelekileyo ibekwe ngasemva kwi-membrane yokutshintsha ukuqinisekisa uzinzo kunye nokhuseleko ngexesha lokusetyenziswa.
