Kusintha kwa ma membrane a PCB

Kusintha kwa Membrane: chida chowongolera molondola pazida zamagetsi

Kusintha kwa Membrane ndi zigawo zowongolera zolondola zomwe zimagwiritsidwa ntchito kwambiri pazida zamagetsi.Amaphatikizidwa mwamphamvu ndi mabwalo a PCB kuti apereke mawonekedwe ogwiritsira ntchito moyenera komanso odalirika ndikuwongolera magwiridwe antchito pazida zamagetsi.

Ukadaulo wapakatikati womwe umagwiritsidwa ntchito pakusintha kwa membrane ndi kusindikiza kozungulira kwakanema.Amapangidwa ndi filimu yopyapyala yokhala ndi mizere yowongolera komanso malo ofunikira omwe amasindikizidwa pamenepo.Pamene kiyi pa nembanemba lophimba mbamuikha, mizere conductive kutseka, kumaliza kugwirizana dera.Kapangidwe kameneka kamapangitsa kusintha kwa membrane kukhala komveka bwino komanso kolondola.

Ubwino umodzi wa masiwichi a membrane ndi kapangidwe kake kosavuta.Zimakhala ndi gawo limodzi lokha la zinthu zowonda zamakanema, zomwe zimawapangitsa kukhala ang'onoang'ono komanso opepuka kuposa masiwichi amakina achikhalidwe.Izi zimawapangitsa kukhala oyenerera bwino pamapangidwe amagetsi amagetsi.Kusintha kwa ma Membrane kumakhalanso ndi moyo wautali wautumiki ndipo kumatha kupirira kukakamiza kwambiri pafupipafupi.

Kudalirika kwa masiwichi a membrane ndi chifukwa china cha kutchuka kwawo.Popeza amapangidwa pogwiritsa ntchito njira yosindikizira, kupanga kulondola kwa mizere ya conductive kumatha kuyendetsedwa molondola, kuchepetsa kulephera.Kuphatikiza apo, kusinthika kwazinthu zamakanema kumapangitsa kuti zisagwedezeke komanso kugwedezeka, zomwe zimapangitsa kuti zizigwira ntchito mokhazikika m'malo ovuta.

Kuphatikiza apo, ma switch a membrane amatha kusinthidwa mwamakonda.Opanga amatha kuzipanga ndikuzisintha mwamakonda ndi makulidwe osiyanasiyana kuti zikwaniritse zofunikira zogwirira ntchito.Kusinthasintha kumeneku kumapangitsa masiwichi a membrane kukhala chinthu chofunikira kwambiri popanga zida zamagetsi.

Mwachidule, kusintha kwa membrane kumagwira ntchito yofunika kwambiri pazida zamagetsi.Amaphatikizidwa mwamphamvu ndi mabwalo a PCB kuti apereke mawonekedwe ogwiritsira ntchito moyenera komanso odalirika komanso kuwongolera magwiridwe antchito pazida zamagetsi.Kapangidwe kake, kudalirika kwakukulu, kukhudzika kwambiri, komanso kulondola kwa ma switch a membrane kumawapangitsa kukhala chida chofunikira kwambiri chowongolera popanga zida zamakono zamakono.

Kapangidwe kozolowereka kosinthira kwa membrane nthawi zambiri kumaphatikizapo zigawo zikuluzikulu izi:

1. Zojambula Zojambula: Gawo lalikulu la kusintha kwa nembanemba limapangidwa ndi zojambulajambula, nthawi zambiri filimu ya polyester kapena filimu ya polycarbonate.Izi filimu zinthu ndi kusintha ndi cholimba, oyenera ntchito kiyi.

2. Zomatira Zomatira: Zomatira zomata za switch ya nembanemba zimagwiritsidwa ntchito kuti zigwirizane ndi shrapnel wosanjikiza ndi gulu la filimu mu switch ya membrane.Imayikidwa pazithunzi zopindika ndikupewa malo a makiyi ndi mawindo.

3. Dome retainer: Iyi ndi gawo la kusintha kwa nembanemba komwe kumagwiritsidwa ntchito kusunga zitsulo zamatabwa (zomwe zimatchedwanso kuti spring tabu kapena tabu yokhudzana ndi kasupe).Dome lachitsulo ndi chimodzi mwazinthu zofunika kwambiri pakusintha kwa membrane.Ndi zotanuka kotero kuti fungulo likakanikizidwa, limapindika ndikulumikizana ndi conductive layer kuti likwaniritse kutsekedwa kwa dera.Ntchito ya wosanjikiza wosungira ndikukonza dome lachitsulo pamalo olondola kuti liwonetsetse kuti limagwira ntchito bwino pamene fungulo likukakamizidwa.

4. Zomatira za Spacer: Zomatira za spacer, zomwe zimadziwikanso kuti spacer adhesive, ndi spacer layer yomwe imagwiritsidwa ntchito mu membrane switch ndi zomatira mbali zonse.Ntchito yake yayikulu ndikupanga spacer pakati pa dome retainer ndi cirucit wosanjikiza wa membrane switch ndikupereka kuthamanga koyenera ndi mtunda kuti zitsimikizire kusintha koyenera.The spacer for membrane switches nthawi zambiri amapangidwa ndi zinthu zapadera zomatira, monga filimu ya poliyesitala kapena filimu ya polyether.Zidazi zimakhala ndi zomatira zabwino ndipo zimamangiriza chowongolera ku gawo lapansi panthawi yophatikiza kusintha kwa membrane.

5. Circuit layer: Mabwalo oyendetsa amapangidwa pafilimuyo kudzera munjira monga kusindikiza kapena etching.Ma conductive siliva phala kapena conductive inki ya kaboni ndi zida zomwe zimagwiritsidwa ntchito kwambiri pamabwalo awa.Zida zopangira izi zimalola kusintha kwa nembanemba kuti kutseke kutsekeka panthawi yofunikira.

6. Zomatira kumbuyo: Ndi zomatira kapena zomatira zomwe zimagwiritsidwa ntchito kumbuyo kwa chosinthira cha membrane.Ndilo gawo lofunikira pakuteteza kusintha kwa nembanemba kupita ku gawo lapansi kapena chipangizo china chomwe amachiyikapo.Nthawi zambiri imakhala kumbuyo kwa chosinthira cha membrane kuti zitsimikizire kukhazikika komanso chitetezo pakagwiritsidwe ntchito.
