Kodi Zida Zamagetsi Zamagetsi Zingagwiritsidwe Ntchito Pama PCB Olimba Komanso Osinthika?

Electronic potting zinthu Ndikofunikira popereka kutchinjiriza ndi kuteteza zida zamagetsi ndi zozungulira kuzinthu zowononga zachilengedwe - chinyezi, fumbi, kugwedezeka - ndikupatsa PCB (Printed Circuit Board) chithandizo chowonjezera chamakina. Zonse ndikupereka kudalirika komanso kulimba kuti tiwonjezere zamagetsi zathu zatsiku ndi tsiku.

 

Msikawu umapereka zida zopangira miphika, iliyonse ili ndi zinthu zapadera zomwe zimawapangitsa kukhala oyenera ntchito zapadera. Epoxy resins amabweretsa kusinthasintha; polyurethane resins amapereka matenthedwe matenthedwe; mphira wa silikoni umapereka kukana kwamankhwala olimba, pomwe zida za thermoplastic zimawonekera munthawi yakuchiritsa. Kuti muwonetsetse kuti mwapeza zoyenera pulojekiti yanu, lingalirani za kutentha kwa ntchito, milingo yachitetezo kapena zomwe ziyenera kukhala zamakina.

Kodi Zida Zamagetsi Zamagetsi Zingagwiritsidwe Ntchito Pama PCB Olimba Komanso Osinthika?

Kuyenda molunjika pamtima pa nkhaniyi - atha zinthu zamagetsi potting igwire yokha ndi ma PCB olimba komanso osinthika? Ma PCB olimba amamangidwa kuchokera ku zinthu zolimba monga fiberglass kapena epoxy resin, pomwe ma flexi-PCBs owonjezera amatuluka kuchokera kuzinthu zosinthika. Ndikodi kusiyana kwa usiku ndi usana pakati pawo - kulimba kapena kuuma kwawo.

 

Kumasuka kodziwikiratu komwe kumadza chifukwa chopeza zinthu zonse zopangira miphika kwa onse awiri kunatipangitsa kuti titha kufewetsa njira yathu yopangira zinthu, nthawi yomweyo kuchepetsa mtengo ndikuchepetsa zovuta zowongolera zinthu, ndikuwonetsetsa kuti timagwira ntchito mokhazikika & kudalirika pamitundu yosiyanasiyana ya ma PCB.

 

Traditional potting zipangizo okhwima PCBs

Kwa zaka zambiri, ma epoxy resins atsimikizira kukhala odalirika poyika ma PCB osiyanasiyana okhwima. Ali ndi chilichonse: kuyambira kumphamvu ndi kukana kwamankhwala mpaka kukhazikika kwamafuta ndi kukwanitsa kukwanitsa - zinthu zolimba! Komabe, chitetezo choyika chilichonse cha nyenyeziyi chili ndi zovuta zina; kukhala owuma ndi osasunthika kumawapangitsa kukhala osayenera pamene kusinthasintha kuli kofunikira, pamene kutentha kwawo kwapamwamba kungathe kukhala kovuta ndi zigawo zomwe sizimva kutentha.

 

Ma resin a polyurethane amayika bokosilo ngati mukufuna china chake chosavuta kusungunula, pomwe mphira wa silikoni umakulitsa mphamvu zanu zotchinjiriza zamagetsi ndipo amapereka ntchito zabwino kwambiri pakatentha kwambiri. Ngakhale zosankha zonsezi zitha kukulitsa mtengo pang'ono poyerekeza ndi epoxy resin, zimaperekabe phindu lapadera.

 

Zovuta pakuyika ma PCB osinthika

Potting flex PCBs ndi chiyembekezo chonyenga - amatha kupindika ndi kupindika, kotero kuti zinthu zophika ziyenera kukhala zolimba, ngakhale pamaso pa kutambasula ndi kusuntha konseko. Kuphatikiza apo, iyenera kukhala yomatira popanda matuza kapena thovu!

 

Zomatira pamayikidwe osinthika zimaperekanso vuto; Ngati miphika yanu siyikugwirizana nayo (ie, siyikuyenda bwino), mulibe mwayi pakuyika bwino.

 

Ndipo chimenecho sichiwopsezo chaching'ono poganizira zoopsa zamtundu wanji zomwe zitha kubweretsa chinyezi. Mfundo yofunika: ngati mukufuna kukonza ma PCB osinthika, kuonetsetsa kuti muli ndi zida zoyenera ndikofunikira.

 

Ubwino wogwiritsa ntchito potting pakompyuta pama PCB osinthika

Ma PCB osinthika amabwera ndi zovuta zawo; komabe, kukhala ndi zida zamagetsi kumbali yanu kumatha kubweretsa zabwino zingapo - kusinthasintha kukhala chinthu chachikulu. Zipangizo zamagetsi zamagetsi zimapangidwa kuti zizipinda ndi kupindika mobwerezabwereza popanda kusweka kapena kulekanitsa, zabwino kwambiri kuposa utomoni wamba wa epoxy. Kuwonetsetsa kuti zigawo zonse ndi zozungulira zimakhalabe zosavulazidwa ngakhale zitasinthidwa zimapatsa malire ena.

 

Kuti mutetezedwe mowonjezereka ku kuwonongeka kwa chilengedwe monga chinyezi, fumbi, ndi kugwedezeka - palibe chinthu chofanana ndi zida zamagetsi! Pamene imapanga chishango kuzungulira zigawo zonse, madzi amakanidwa khomo, kuchepetsa chiopsezo cha dzimbiri; Kuphatikiza apo, imabisa kugwedezeka mochenjera, zomwe zimathandiza kuchepetsa kuwonongeka komwe kumachitika chifukwa cha kupsinjika kwamakina.

 

Zipangizo zamagetsi zamagetsi zimaonekera bwino zikaphatikizidwa ndi mitundu yosiyanasiyana ya magawo - polyimide ndi polyester-derived flexible PCB, mwachitsanzo- zimamamatira mosavuta chifukwa cha zomatira. Izi zimapanga mgwirizano wodalirika pakati pa magawo onse awiri, kuteteza kulekana pa mtengo uliwonse.

 

Kusiyana pakati pa ma PCB olimba ndi osinthika

Ma PCB olimba komanso osinthika amakhala pafupifupi usana ndi usiku - imodzi yolimba ngati mwala, ina yopindika ngati njoka. Zinthu zomwe amapangidwazo zimakhudza kwambiri mawonekedwe awo m'njira zina zochititsa chidwi. Ngati mungatengeke, zomwe zimagwira ntchito pama board olimba sizingafanane ndi zosinthika.

 

Kusiyanaku kukutanthauza kuti kusankha chinthu chophika sikophweka: kusankha kwanu kudzadalira momwe zimakhalira zolimba kapena zokhotakhota zonse zikanenedwa! Pamasitepe omwe akuyenera kukhala olimba - lingalirani ma PCB amtundu wouma - tikufunika china chake chopatsa mphamvu zamakina ndi chitetezo chowonjezereka ku kuwonongeka kwa chilengedwe.

 

Koma kumene kusinthasintha kuli kofunika kwambiri, tidzapita ku chinthu china cholimba kuti tipirire mobwerezabwereza popanda kuwonongeka.

 

Pomaliza, tipeweninso lingaliro la kukana kutentha. Panthawi imodzimodziyo, kutentha kwambiri sikungakhale kolimba; asuweni awo ogulitsa sangawotche kwambiri, choncho sankhani kutentha moyenerera kapena muyembekezere zotsatira zochepa kwambiri mukamaliza.

 

Kuyesa ndi kutsimikizika kwa zinthu zamagetsi zamagetsi zama PCB osinthika

Kuyesa ndi kutsimikizira ndizofunikira kwambiri pakuwonetsetsa kuti zinthu zamagetsi zamagetsi zomwe zimagwiritsidwa ntchito mu PCB zikuyenda bwino. Kupeza chogwirizira pa zinthu zomwe zingakhale zoperewera kumathandiza kuonetsetsa kuti zikukwaniritsa zofunikira zonse.

 

Kuyeza kwa njinga zamoto ndi njira yotsimikizirika yowunikira kudalirika kwa zinthuzi pansi pa kutentha kosiyana. Zimatilola kutulutsa luso - kapena kusowa kwake - zomwe mwina sizinawululidwe mwanjira ina.

 

Mayeso osinthika ayeneranso kuchitidwa ponena za ma PCB omwe amayenera kupindika kapena kusinthasintha pakagwiritsidwe ntchito! Izi zimathandiza kudziwa ngati zidutswazo zimatha kupindika mobwerezabwereza popanda kuwonetsa zowonongeka monga kusweka kapena delamination.

 

Pomaliza, palinso kuyezetsa kukana chinyezi, kuyezetsa kukana kwa mankhwala ndi kuyesa kwa magetsi ngati zinthu zofunika kwambiri kuti muwone ngati zinthuzi zitha kuteteza mokwanira ku zotsatira monga kulowerera kwa madzi.

Mawu Otsiriza

Electronic potting zinthu imagwedeza nyumbayo ma PCB osasinthika komanso osinthika. Ngakhale zinthu zakale zakusukulu zakale zinali zabwino kwambiri pa PCB zosasinthika, sizingadule ndi zopindika. Zida zamagetsi zimatha kuchita zonse - kupereka kusinthasintha kodabwitsa komanso kulimba komwe kumakwaniritsa zosowa za gulu lililonse.

 

Zinthu zamtunduwu zimapindula chifukwa mumapeza chitetezo chosagonjetseka ku zosokoneza zachilengedwe, palibenso zovuta zofananira (chifukwa cha magawo ake ambiri) komanso kudalirika kwapamwamba kwambiri. Ngakhale zovuta zina monga kuwira kwa mpweya kapena zomatira zitha kuwoneka mwachidule paulendo wanu wa PCB, zigwetseni ndikuyesa zina zisanakhale zovuta.
