Ukutshintshela inwebu yePCB
PCB inwebu iswitsha kuthetha ukuba ipateni kunye nesekethe iswitshi zenziwa kwisiqhelo eprintiweyo yesekethe enxibe ibhodi yobhedu.
Uphawu PCB inwebu iswitsha kukuba izinto kulula ukuyisebenzisa, inkqubo uzinzile, ukuxhathisa liphantsi, kwaye amanye amacandelo kwisekethe inokudityaniswa ngqo ngasemva PCB.Kwimeko yendawo encinci, i-hard liner layer ingashiywa.I-PCB inokwenziwa ngobukhulu obuyi-0.5mm-3.0mm.
Izitshixo ze-PCB inwebu ziqhele ukusebenzisa izikhokelo zentsimbi njengabafowunelwa be-labyrinth conductive, ngoko ke baziva ngcono.Ukungalungi kukuba akulula njengokutshintsha kwe-membrane eguquguqukayo ukufaka kunye nokudibanisa kuwo wonke umatshini, kwaye kudla ngokuyimfuneko ukuba udibanise isinxibelelanisi kwaye ukhokele ukukhokela ngentambo yeflethi.Ukongeza kwisiginali ye-buzzer kunye ne-LED isibonakaliso, ingxelo yolwazi lokutshintsha kwe-membrane eqinile inokusebenzisa ngokubanzi i-shrapnel yokubamba isinyithi.
Amagama anxulumene nemveliso: iswitsha yenwebu, isitshixo senwebu, ikhibhodi yenwebu, ikhibhodi yeFPC, ikhibhodi yePCB, inwebu yesitshixo sombane,
Ukutshintshela inwebu yokudlala, iswitshi yokuchukumisa i-capacitive, iswitshi yokulawula inwebu, ishidi yesekethe ye-electrode yonyango, iswitshi ye-membrane engenamanzi,
I-LGF yokutshintsha inwebu ekhanyayo, ikhibhodi ye-membrane ye-LED, iswitshi yomgca webhodi yezitshixo, ikhibhodi engangeni manzi, ikhibhodi ye-membrane, iqhosha lokutshintsha elincinci kakhulu.Ukutshintsha kwenwebu yomlawuli
