Ib daim nyias nyias yog hais txog PCB circuits thiab hloov tau yooj yim circuits

Membrane keyboards yog cov khoom siv hluav taws xob tswj hluav taws xob uas muaj qhov hloov pauv ntawm daim nyias nyias, daim nyias nyias, thiab qhov sib txuas.Lub vaj huam sib luag ntawm daim nyias nyias tuaj yeem ua silk-screen luam los tswj cov tsos ntawm cov khoom, qhia cov qauv thiab cov cim.Lub membrane ciruits feem ntau ua haujlwm raws li kev tswj xyuas hluav taws xob, thaum qhov kev sib txuas txuas txuas cov membrane hloov mus rau lub tshuab davhlau ya nyob twg, ua kom muaj kev tswj hwm ntawm lub tshuab davhlau ya nyob twg.Thaum tus yuam sij ntawm qhov hloov pauv ntawm daim nyias nyias raug nias, cov kab hluav taws xob yuav kaw, ua kom tiav qhov kev sib txuas hauv Circuit Court.

Tej yam yooj yim membrane keyboards siv PET screen printing silver paste raws li kev tswj kab.Txawm li cas los xij, rau cov khoom uas xav tau kev ruaj ntseg thiab kev ua haujlwm nyuaj, PCB lossis FPC kab feem ntau yog siv.Qee zaum, kev sib xyaw ntawm PCB thiab FPC txheej txheem tuaj yeem siv tau.

PCB yog lub rooj tsav xwm luam tawm, nws yog lub substrate siv los txhawb thiab txuas cov khoom siv hluav taws xob.Nws feem ntau yog ua los ntawm cov ntaub ntawv insulating thiab luam tawm nrog cov kab hluav taws xob thiab cov haujlwm rau mounting cov khoom siv hluav taws xob.PCB tsim muaj qhov yooj yim, muaj kev ntseeg siab, thiab rov siv tau dua, ua rau nws yog ib qho tseem ceeb thiab tseem ceeb ntawm cov khoom siv hluav taws xob niaj hnub no.

FPC yog lub rooj tsavxwm hloov tau yooj yim, nws yog ib qho yooj yim substrate uas tuaj yeem khoov thiab folded.Nws yog tsim rau cov khoom siv hluav taws xob uas yuav tsum tau khoov lossis muaj qhov chaw txwv.FPC circuits yog me me, hnyav, thiab txhim khu kev qha, ua rau lawv siv dav hauv kev tswj cov khoom siv hluav taws xob.
