Ukushintsha kwe-membrane ye-PCB

Ukushintsha ulwelwesi lwe-PCB kusho ukuthi iphethini kanye nesekhethi yeswishi yenziwa ebhodini eligqoke ithusi elivamile eliphrintiwe.

Isici sokushintshwa kolwelwesi lwe-PCB ukuthi impahla kulula ukuyisebenzisa, inqubo izinzile, ukumelana kuphansi, futhi ezinye izingxenye ezisesekethe zingashiselwa ngqo ngemuva kwe-PCB.Endabeni yendawo encane, ungqimba oluqinile lwe-liner lungashiywa.I-PCB ingenziwa ngogqinsi luka-0.5mm-3.0mm.

Amaswishi ulwelwesi lwe-PCB ngokuvamile asebenzisa imihlahlandlela yensimbi njengabathintwayo be-labyrinth, ngakho banomuzwa ongcono.Ububi ukuthi akulula njengokushintshwa kwe-membrane eguquguqukayo ukufaka nokuxhuma kuwo wonke umshini, futhi ngokuvamile kuyadingeka ukushisela isixhumi futhi uhole umthofu ngekhebula eliyisicaba.Ngokungeziwe kusiginali ye-buzzer nenkomba ye-LED, impendulo yolwazi yeswishi ye-membrane eqinile ngokuvamile ingasebenzisa i-shrapnel yesibambo sensimbi.

Amagama ahlobene nomkhiqizo: ukushintshwa kwe-membrane, ukhiye we-membrane, ikhibhodi ye-membrane, ikhibhodi ye-FPC, ikhibhodi ye-PCB, ulwelwesi lukakhiye kagesi,

I-toy membrane switch, i-capacitive touch switch, iswishi yokulawula ulwelwesi, ishidi le-electrode yesifunda sezokwelapha, ukushintshwa kolwelwesi olungangeni manzi,

Iswishi yolwelwesi olukhanyayo lwe-LGF, ikhibhodi yolwelwesi lwe-LED, iswishi yomugqa wekhibhodi, ikhibhodi engangeni manzi, ikhibhodi yolwelwesi, inkinobho yokushintsha izacile kakhulu.Ukushintsha kwe-membrane yesilawuli

Amapharamitha ahlobene

Amapharamitha wokushintsha kwe-Membrane
Izakhiwo zikagesi I-voltage esebenzayo: ≤50V (DC) Ukusebenza kwamanje:≤100mA
Ukumelana nokuxhumana:0.5~10Ω Ukumelana ne-insulation: ≥100MΩ (100V/DC)
Ukumelana nengcindezi ye-substrate: 2kV (DC) Isikhathi sokuphindaphinda:≤6ms
Ukumelana ne-loop: 50 Ω, 150 Ω, 350 Ω, noma kunqunywa ngokuya ngezidingo zomsebenzisi. Uyinki wokuvikela ukumelana ne-voltage: 100V/DC
izakhiwo zemishini Impilo yesevisi enokwethenjelwa:>Izikhathi eziyisigidi Ukususwa kokuvala: 0.1 ~ 0.4mm (uhlobo oluthintekayo) 0.4 ~ 1.0mm (uhlobo oluthintayo)
Amandla okusebenza: 15 ~ 750g Ukufuduka kwe-conductive silver paste: ku-55 ℃, izinga lokushisa elingu-90%, ngemva kwamahora angu-56, kungu-10m Ω / 50VDC phakathi kwezintambo ezimbili.
Akukho i-oxidation nokungcola emgqeni wokunamathisela wesiliva Ububanzi bomugqa wokunamathisela kwesiliva bukhulu noma bulingana no-0.3mm, isikhawu esincane singu-0.3mm, umkhawulo onzima womugqa ungaphansi kuka-1/3, futhi igebe lomugqa lingaphansi kuka-1/4
Izikhala zephinikhodi 2.54 2.50 1.27 1.25mm Ukumelana nokugoba komugqa ophumayo izikhathi ezingama-80 ngo-d = 10 mm induku yensimbi.
Imingcele yemvelo Izinga lokushisa elisebenzayo: -20℃~+70℃ Izinga lokushisa lesitoreji: - 40 ℃ ~ + 85 ℃, 95% ± 5%
Ukucindezela komkhathi:86–106KPa
Inkomba yenkomba yokuphrinta Ukuchezuka kosayizi wokuphrinta kungu-± 0.10 mm, umugqa oseceleni wohlaka awucacile, futhi iphutha lokuluka ngu-± 0.1 mm Ukuchezuka kwechromatic kungu-± 0.11mm/100mm, futhi ulayini wokunamathisela oyisiliva umbozwe ngokuphelele uyinki wokuvikela.
Awukho uyinki ohlakaziwe, akukho mbhalo wesandla ongaphelele Umehluko wombala awukho ngaphezu kwamazinga amabili
Akumele kube khona ukuxebuka noma ukuxebuka kopende Iwindi elibonisa ngale kufanele libe sobala futhi lihlanzeke, libe nombala ofanayo, lingabi nemihuzuko, izimbobo kanye nokungcola.
