PCB membrane canza
PCB membrane canza yana nufin cewa tsari da da'irar na canji an yi a kan kowa buga kewaye da tagulla clad jirgin.
Halin canjin membrane na PCB shine cewa kayan yana da sauƙin amfani, tsarin yana da ƙarfi, juriya yana da ƙasa, kuma wasu abubuwan da ke cikin da'irar za a iya haɗa su kai tsaye a bayan PCB.A cikin yanayin ƙaramin yanki, za a iya tsallake Layer Layer Layer.Ana iya yin PCB tare da kauri na 0.5mm-3.0mm.
PCB membrane yana canzawa gabaɗaya suna amfani da jagororin ƙarfe azaman lambobin labyrinth masu gudanarwa, don haka suna da daɗi.Rashin hasara shi ne cewa bai dace ba kamar yadda maɓalli mai sassauƙa don shigarwa da haɗawa a cikin injin duka, kuma sau da yawa ya zama dole don walda mai haɗawa kuma ya jagoranci jagora ta hanyar kebul na lebur.Baya ga siginar buzzer da nunin LED, bayanin bayanin madaidaicin canjin membrane na iya amfani da shrapnel na hannu gabaɗaya.
