Mabwalo a PCB ngati chosinthira choyambira kamangidwe ka membrane
Makina osinthira a PCB (Printed Circuit Board) ndi mtundu wa mawonekedwe amagetsi omwe amagwiritsa ntchito nembanemba yopyapyala, yosinthika kuti ilumikizane ndikugwiritsa ntchito magawo osiyanasiyana ozungulira.Masinthidwe awa amapangidwa ndi zigawo zingapo zazinthu, kuphatikiza mabwalo osindikizidwa, zigawo zoteteza, ndi zomatira, zonse zokonzedwa kuti zipange msonkhano wosinthira wophatikizika.Zomwe zimafunikira pakusintha kwa membrane ya PCB zikuphatikiza bolodi la PCB, zokutira zojambulidwa, ndi chingwe chowongolera.The PCB board imagwira ntchito ngati maziko osinthira, ndikuphimba kwazithunzi komwe kumapereka mawonekedwe omwe akuwonetsa ntchito zosiyanasiyana zosinthira.Chosanjikiza cha membrane chimagwiritsidwa ntchito pa bolodi la PCB ndipo chimakhala ngati njira yosinthira popereka chotchinga chakuthupi chomwe chimayendetsa mabwalo osiyanasiyana ndikutumiza zidziwitso ku zida zofananira.Ntchito yomanga kansalu ya PCB imakhala yolimba kwambiri komanso yokhalitsa, yomwe imawapanga kukhala abwino kuti agwiritsidwe ntchito pazinthu zosiyanasiyana, kuchokera ku zipangizo zamagetsi zamagetsi kupita ku zipangizo zamankhwala ndi makina a mafakitale.Amakhalanso osinthika kwambiri, omwe amatha kupanga masanjidwe ndi mapangidwe ake, ndipo amatha kusinthidwanso ndi zina zowonjezera monga ma LED, mayankho a tactile, ndi zina zambiri.

PCB imaphatikiza gawo la FPC membrane
Ukadaulo wa PCB-based Flexible Printed Circuit (FPC) ndi njira yotsogola yopangira dera pomwe gawo losinthika limasindikizidwa pagawo lopyapyala komanso losinthika, monga pulasitiki kapena filimu ya polyimide.Imakhala ndi maubwino angapo kuposa ma PCB okhazikika, monga kusinthasintha bwino komanso kukhazikika, kachulukidwe kake kosindikizidwa, komanso kutsika mtengo.Ukadaulo wa FPC wozikidwa pa PCB utha kuphatikizidwa ndi njira zina zamapangidwe ozungulira ngati mapangidwe a membrane kuti apange gawo losakanizidwa.Dera la membrane ndi mtundu wozungulira womwe umapangidwa pogwiritsa ntchito zigawo zoonda komanso zosinthika zakuthupi monga poliyesitala kapena polycarbonate.Ndilo njira yotchuka yopangira mapulogalamu omwe amafunikira mawonekedwe otsika komanso kulimba kwambiri.Kuphatikiza ukadaulo wa FPC wozikidwa pa PCB ndi kapangidwe ka membala wa membrane kumathandiza opanga kupanga mabwalo ovuta omwe amatha kusintha mawonekedwe ndi mawonekedwe osiyanasiyana osataya magwiridwe antchito.Njirayi imaphatikizapo kugwirizanitsa zigawo ziwiri zosinthika pamodzi pogwiritsa ntchito zomatira, zomwe zimapangitsa kuti dera likhale losinthasintha komanso lokhazikika.Kuphatikizika kwaukadaulo wa FPC wozikidwa pa PCB wokhala ndi kamangidwe ka membala wa membrane nthawi zambiri amagwiritsidwa ntchito m'njira zosiyanasiyana monga zida zamankhwala, zamagetsi zamagetsi, zida zamafakitale, ndi zida zamagalimoto.Ubwino wa njira yopangira ma hybrid circuit ikuphatikizapo kuchita bwino, kuchepetsa kukula ndi kulemera kwake, komanso kusinthasintha komanso kulimba.

ESD chitetezo membrane circuit
ESD (Electrostatic Discharge) yoteteza nembanemba, yomwe imadziwikanso kuti ESD kupondereza nembanemba, idapangidwa kuti iteteze zida zamagetsi kuti zisatulutsidwe ndi ma electrostatic discharge, zomwe zimatha kuwononga zinthu zomwe sizingathe kutheka.Ma nembanembawa amagwiritsidwa ntchito molumikizana ndi njira zina zodzitetezera za ESD monga kuyika pansi, pansi, ndi zovala zoteteza.Ma membrane achitetezo a ESD amagwira ntchito poyamwa ndikuchotsa zolipiritsa zokhazikika, kuwalepheretsa kudutsa nembanemba ndikufika pazinthu zamagetsi.

Multilayer circuit membrane switch
Chosinthira chamitundu yambiri chamitundu yosiyanasiyana ndi mtundu wa masinthidwe a membrane omwe amapangidwa ndi zigawo zingapo, chilichonse chimakhala ndi cholinga chake.Nthawi zambiri imakhala ndi gawo la polyester kapena polyimide gawo lapansi lomwe limakhala ngati maziko osinthira.Pamwamba pa gawo lapansili, pali zigawo zingapo zomwe zimaphatikizapo gawo lapamwamba losindikizidwa, zomatira, zomangira zapansi za FPC, zomatira, ndi zojambulajambula.Chigawo chosindikizidwa chimakhala ndi njira zoyendetsera zomwe zimagwiritsidwa ntchito kuti zizindikire pamene chosinthira chatsegulidwa.Chomata chimagwiritsidwa ntchito kulumikiza zigawozo, ndipo chophimbacho ndi chapamwamba chomwe chimawonetsa zilembo ndi zithunzi za switch.Masinthidwe amitundu yambiri amapangidwa kuti azikhala olimba komanso odalirika, kuwapangitsa kukhala abwino kugwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza zida zamankhwala, zamagetsi zamagetsi, zida zamagetsi, ndi zida zamafakitale.Amapereka maubwino monga mawonekedwe otsika, mapangidwe osinthika, komanso kugwiritsa ntchito mosavuta, kuwapangitsa kukhala chisankho chodziwika bwino pazida zamagetsi.
