PCB kuphatikiza FPC nembanemba wozungulira Chithunzi Chowonetsedwa

PCB imaphatikiza gawo la FPC membrane

Kufotokozera Kwachidule:

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.

Kugwiritsa ntchito

Kusintha kwa membrane iyi ndi njira yabwino yothetsera mabwalo a PCB, mabwalo a FPC, ndi solder ya FPC ku ma PCB olumikizirana nawo.Imagwiritsa ntchito ukadaulo waposachedwa wa Hot bar kuti ulumikizane ndi odalirika ndipo umabwera ndi chowumitsa mchira kuti ukhale wolimba.Kusinthaku ndikokhazikika kwambiri ndipo kumapereka magwiridwe antchito kwanthawi yayitali.Ndiwosavuta kukhazikitsa ndi kukonza, ndikupangitsa kuti ikhale chisankho chabwino pantchito iliyonse.Ndi mawonekedwe ake apamwamba komanso kapangidwe kodalirika, kusintha kwa membrane uku ndikutsimikiza kukupatsani chidziwitso chabwino.

Dera la PCB ili ndilabwino pantchito iliyonse yomwe ikufuna kupangidwa kodalirika komanso kolimba.Imakhala ndi masiwichi achitsulo a domes, omwe amapereka kuyankha kwamphamvu akakanikizidwa ndikupangitsa kuti ikhale yosavuta kugwiritsa ntchito.Kuphatikiza apo, derali lili ndi msonkhano wa LED, womwe umapereka chiwonetsero chowoneka bwino.Ndi chisankho chabwino kwa polojekiti iliyonse yamagetsi yomwe ikufunika dera lodalirika komanso lokhalitsa la PCB.
