I-PCB ihlanganisa i-FPC membrane circuit
Ubuchwepheshe obususelwa ku-PCB obususelwa ku-Flexible Printed Circuit (FPC) buyindlela ethuthukisiwe yokuklama isekethe lapho isekethe eguquguqukayo iphrintwa ku-substrate encane futhi eguqukayo, njengepulasitiki noma ifilimu ye-polyimide.Inikeza izinzuzo ezimbalwa kuma-PCB endabuko aqinile, njengokuguquguquka okungcono nokuqina, ukuminyana okukhulu kwesekethe ephrintiwe, kanye nezindleko ezincishisiwe.Ubuchwepheshe be-FPC obusekelwe ku-PCB bungahlanganiswa nezinye izindlela zokuklama isekethe njengedizayini yesekethe ye-membrane ukuze kwakhiwe isekethe eyingxube.Isekhethi ye-membrane wuhlobo lwesekethe olwenziwa kusetshenziswa izendlalelo ezincane neziguquguqukayo zezinto ezifana ne-polyester noma i-polycarbonate.Kuyisixazululo esidumile sokuklama izinhlelo zokusebenza ezidinga iphrofayili ephansi nokuqina okuphezulu.Ukuhlanganisa ubuchwepheshe be-FPC obusekelwe ku-PCB nomklamo wesekethe ye-membrane kusiza abaklami ukuthi bakhe amasekhethi ayinkimbinkimbi angakwazi ukuzivumelanisa nezimo namafomu ahlukahlukene ngaphandle kokulahlekelwa ukusebenza kwawo.Inqubo ihilela ukuhlanganisa izingqimba ezimbili eziguquguqukayo ndawonye usebenzisa into yokunamathela, okuvumela isifunda ukuthi sihlale siguquguquka futhi siqinile.Inhlanganisela yobuchwepheshe be-FPC obusekelwe ku-PCB enomklamo wesekethe ye-membrane ivame ukusetshenziswa ezinhlelweni ezihlukahlukene ezifana nemishini yezokwelapha, izinto zikagesi zabathengi, okokusebenza kwezimboni, kanye nezingxenye zezimoto.Izinzuzo zale ndlela yokuklama isekethe eyingxubevange ihlanganisa ukusebenza okuthuthukisiwe, usayizi oncishisiwe nesisindo, kanye nokukhula kokuguquguquka nokuqina.

Isekhethi yokuvikela ulwelwesi lwe-ESD
I-ESD (Electrostatic Discharge) yokuvikela ulwelwesi, eyaziwa nangokuthi i-ESD suppression membranes, yakhelwe ukuvikela izinto zikagesi ekukhishweni kwe-electrostatic, okungadala umonakalo ongalungiseki ezingxenyeni ze-elekthronikhi ezibucayi.Lawa ma-membrane ngokuvamile asetshenziswa ngokuhambisana nezinye izindlela zokuvikela ze-ESD ezifana nokuphansi, i-conductive flooring, nezingubo zokuzivikela.Ama-membrane okuvikela e-ESD asebenza ngokumunca futhi ahlakaze amashaji amile, awavimbele ukuthi angadluli kulwelwesi futhi afinyelele izingxenye ze-elekthronikhi.

Ukushintsha kwe-membrane yesekethe enezingqimba eziningi
I-multi-layer circuit membrane switch iwuhlobo lokushintshwa kolwelwesi olwakhiwe ngezingqimba eziningana zezinto, ngayinye inenjongo ethile.Ngokuvamile iqukethe ungqimba lwe-polyester noma i-polyimide substrate esebenza njengesisekelo sokushintshwa.Phezulu kwe-substrate, kunezingqimba eziningana ezihlanganisa isendlalelo sesifunda esiphrintiwe phezulu, isendlalelo sokunamathela, isendlalelo sesifunda se-FPC esingezansi, isendlalelo sokunamathisela, kanye nesendlalelo sokumbondelana okuyisithombe.Isendlalelo sesekethe esiphrintiwe siqukethe izindlela ezisetshenziswayo ezisetshenziselwa ukubona lapho iswishi yenziwe yasebenza.Isendlalelo sokunamathisela sisetshenziselwa ukuhlanganisa izendlalelo, futhi imbondela yesithombe isendlalelo esiphezulu esibonisa amalebula nezithonjana zokushintsha.Amaswishi e-multi-layer membrane membrane aklanyelwe ukuthi aqine futhi athembeke, awenze alungele ukusetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa imishini yezokwelapha, izinto zikagesi ezithengwayo, izinto zikagesi, nemishini yezimboni.Banikeza izinzuzo ezifana nephrofayili ephansi, idizayini eyenzeka ngokwezifiso, kanye nokusebenziseka kalula, okubenza babe ukukhetha okudumile kumishini kagesi.
