Flexible membrane keyboard ndi mtundu wamtundu wa kiyibodi wa membrane.Mtundu wa kiyibodi wa membrane wotere umatchedwa flexible chifukwa wosanjikiza wake wa chigoba, wosanjikiza wodzipatula, ndi zigawo zonse zimapangidwa ndi makanema apapulogalamu omwe ali ndi katundu wosiyanasiyana.
Chingwe chozungulira cha kiyibodi yosinthika ya membrane chimagwiritsa ntchito filimu ya poliyesitala (PET) yokhala ndi magetsi abwino ngati chonyamulira chosinthira dera.Chifukwa cha mphamvu ya filimu ya poliyesitala, kiyibodi ya filimuyi imakhala ndi kutchinjiriza bwino, kukana kutentha, kukana kusinthasintha komanso kulimba kwambiri.Zithunzi za chigawo chosinthira, kuphatikizapo cholumikizira chosinthira ndi mawaya ake otsogolera, amasindikizidwa ndi utoto wocheperako, wowongolera womwe umachiritsa pansi pazikhalidwe zotsika.Chifukwa chake, mawonekedwe a kiyibodi yonse ya nembanemba ali ndi kusinthasintha kwina, komwe sikoyenera kugwiritsidwa ntchito pathupi lathyathyathya, komanso kufananizidwa ndi thupi lopindika.Waya wotsogola wa kiyibodi yosinthika ya membrane amaphatikizidwa ndi thupi losinthira lokha.Popanga kugwirizana kwa gulu losinthira, limasonkhanitsidwa pamalo ena a nembanemba ndikukulitsidwa kunja molingana ndi malo omwe adasankhidwa ndi kutalika kwa mzere wa mapangidwewo ngati chofewa, Waya wotsogola wokhazikika komanso wosindikizidwa umalumikizidwa kumbuyo. kuzungulira kwa makina onse.
1. Kusintha kwa mzere Kusinthana kwa mzere kwenikweni ndiko kusintha kwa nembanemba komwe gulu likuchotsedwa.Nthawi zina, kapena ogwiritsa ntchito omwe ali kale ndi gulu lowonetsera, safuna kusintha kwa membrane, koma kusinthana kwapansi..
2. Mabwalo okhala ndi mbali ziwiri Mabwalo am'mbali awiri amatha kugawidwa m'mitundu iwiri.Mtundu umodzi umasindikizidwa ndi mawaya mbali zonse ziwiri.Bowo laling'ono la pafupifupi 0.5mm limatsegulidwa kumapeto kwa waya, ndipo zinthu zoyendetsera zimatsanuliridwa mu dzenje ili kuti lipange nkhope yakutsogolo.Zimagwirizanitsidwa ndi dera lozungulira kuti likwaniritse ntchito yofunikira;dongosolo lina makamaka kuti dera losindikizidwa lakutsogolo liri mu njira ya X axis, dera lakumbuyo liri mu njira ya Y axis, ndipo maulendo awiriwa sali ogwirizana.Dera lamtunduwu limagwiritsidwa ntchito makamaka pama e-mabuku kapena zamagetsi zina.Zofanana ndi ntchito zomverera.
Kwa mabwalo a monolithic okhala ndi milatho, ma seti awiri a mabwalo akawoloka, inki yotchinga ya UV iyenera kusindikizidwa pakati pawo.Pulogalamuyi idzawonjezera kuchuluka kwa zosindikizira pazenera ndipo mtengo wake udzawonjezekanso.Wopangayo ayesetse kupewa kuwoloka mizere popanganso dera.
