Kodi Conformal Coating for Electronics Ndi Chiyani?

Mumakonda zamagetsi ndi zomwe angachite, koma kodi mudayimapo kuti mudzifunse momwe zimagwirira ntchito? Ntchito zamkati mwa machitidwewa zitha kukhala zodabwitsa. Pamafunika mabwalo amagetsi kuti zida zazikulu ndi zazing'ono ziziyenda. Mabwalo amafunikira chitetezo, ndipo apa ndipamene amafunikira zokutira conformal imabwera mkati. M'masiku amenewo, mapulogalamu okhawo omwe amafunikira utumwi ndi omwe amadutsa munjira ya ma boardboard. Kufunika kwachitetezo kudakula pomwe zida zamagetsi zidachulukira ndikuchepera komanso kuvala.

Conformal coating ndi chinthu chopangidwa ndi polymeric chomwe chimapangidwa makamaka kuti chiteteze zigawo, ma board ozungulira, ndi zamagetsi zina kuzinthu zachilengedwe zomwe zingawavulaze. Zinthuzi zimaphatikizapo kugwedezeka kwa kutentha, kugwedezeka, kuipitsidwa, ndi chinyezi. Chophimbacho chimagwirizana ndi mawonekedwe a PCB osakhazikika, motero amakulitsa kukana kwa dielectric, kudalirika, komanso kukhulupirika kwa magwiridwe antchito.

Zimapangidwa ndi chiyani?

The zokutira conformal ndi utomoni wa polymeric ndipo ukhoza kuchepetsedwa mu zosungunulira ngati kuli kofunikira kuti zinthu ziziyenda bwino komanso kutulutsa bwino. Chitetezo chofunikira chimagwiritsidwa ntchito kusankha mtundu wabwino kwambiri wa utomoni pamagetsi. Chilengedwe chomwe chipangizo chamagetsi chidzagwiritsidwa ntchito ndikukhalapo chimagwiritsidwanso ntchito kupanga chisankho choyenera, komanso mosavuta kukonza ndi kugwiritsa ntchito.

Kodi zokutira zofananira ndi zotani?

Zovala zodziwika bwino zimakhala ndi utomoni ndipo zimatha kuchepetsedwa pogwiritsa ntchito zosungunulira. Iwo ndi theka-permeable; chifukwa chake samasindikiza kwathunthu kapena kutsimikizira madzi zamagetsi. Amagwira ntchito poteteza zida kuti zisawonongeke ndi chilengedwe komanso kuti zikhale zolimba. Zida zokutira zimakhalabe zothandiza kugwiritsa ntchito komanso zosavuta kukonza. Mitundu ya zokutira zomwe mudzakumana nazo ndi izi:

Acrylic utomoni - AR, zokutira za acrylic resin zimapereka chitetezo chapadera, ndizopanda ndalama, ndipo ndizosavuta kugwiritsa ntchito komanso kukonza. Mphamvu zawo za dielectric ndizokwera, ndipo kutsekemera kwawo ndi kukana chinyezi ndikoyenera. Zopaka za acryliczi zimatha kuchotsedwa mwachangu pogwiritsa ntchito zosungunulira zosiyanasiyana komanso popanda kusokonezeka. Kukonzanso ndi kukonza kumapangidwa kukhala kosavuta, kopanda ndalama, komanso kothandiza. Poganizira izi, zokutira za AR sizothandiza polimbana ndi zosungunulira komanso chitetezo cha nthunzi. Mwachitsanzo, sangathe kugwiritsidwa ntchito pazamlengalenga chifukwa cha utsi wamafuta a jet.

Silicone utomoni - SR, utomoni wa silikoni, zokutira zimapereka chitetezo chabwino kwambiri pakutentha kwakukulu. Iwo ali wapamwamba kukana mankhwala ndi kusinthasintha ndi kukana mchere kutsitsi ndi chinyezi. Mtundu woterewu wa conformal ″ sulimbana ndi abrasion, poganizira kuti ndi mphira, koma katunduyu amapangitsa kuti athe kupirira kupsinjika kwamphamvu. Zovala za SR ndizabwino pamagetsi okhala ndi chinyezi chambiri, monga zikwangwani zakunja. Sizosavuta kuchotsa monga zokutira za acrylic; amafunikira zosungunulira zapadera, zonyowa, ndi chipwirikiti pogwiritsa ntchito bafa la akupanga kapena burashi.

Polyurethane / urethane utomoni - UR, utomoni wa urethane, ndi zokutira zofananira ndi zokutira zina zomwe mungapeze. Amatchuka chifukwa cha kukana kwawo kwamankhwala komanso chinyezi. Zopakazo zimalimbananso ndi zosungunulira ndi ma abrasions; motero kuchotsa kwawo ndikovuta kwambiri. Kuchotsa, muyenera ntchito zapaderazi zosungunulira ndi zilowerere kwa nthawi yaitali pamaso mukubwadamuka ntchito burashi kapena akupanga kusamba, monga silikoni utomoni. Amapanga zokutira zabwino kwambiri pazamlengalenga chifukwa kukhudzana ndi nthunzi yamafuta sikuwadetsa nkhawa.

Kuti mudziwe zambiri ndi chiyani zokutira conformal zamagetsi, mutha kupita ku DeepMaterial pa https://www.epoxyadhesiveglue.com/category/epoxy-conformal-coating/ chifukwa Dziwani zambiri.
