Phetoho ea membrane ea PCB
PCB lera switjha bolela hore paterone le potoloho ea fapoha li etsoa ka tloaelehileng hatisitsoeng oa potoloho koporo boto clad.
Tšobotsi ea PCB lera switjha ke hore thepa ke ho le bonolo ho sebelisa, tshebetso e tsitsitse, ho hanyetsa e tlaase, 'me likarolo tse ling tsa potoloho ka ka ho toba welded ka morao PCB.Tabeng ea sebaka se senyenyane, lesela le thata la liner le ka tlosoa.PCB e ka etsoa ka botenya ba 0.5mm-3.0mm.
Li-membrane tsa PCB hangata li sebelisa litataiso tsa tšepe e le likhokahano tse tsamaisang labyrinth, kahoo li ikutloa hamolemo.Phoso ke hore ha e tšoanelehe joalo ka ha sesebelisoa sa lera se tenyetsehang ho kenya le ho hokela mochining kaofela, 'me hangata hoa hlokahala ho tjheseletsa sehokelo le ho etella pele ka mohala o bataletseng.Ntle le lets'oao la buzzer le lets'oao la LED, maikutlo a tlhahisoleseling a sesebelisoa se thata sa membrane hangata a ka sebelisa shrapnel ea tšepe.
