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.
