Epoxy potting compound for PCB: zosankha ndi maubwino

Ma PCB kapena matabwa osindikizidwa ali ndi zigawo zofunika kwambiri pamagetsi aliwonse. Iwo ndi abwino kwambiri ngati mukufuna kuteteza zigawozo ku zowonongeka zamtundu uliwonse. Njira ziwiri zimagwiritsidwa ntchito kuteteza zigawozo. Izi ndi zokutira conformal ndi zokutira PCB.

Muzochitika zonsezi, ma polima a organic amateteza zida zamagetsi ndi ma PCB. Pali kusiyana ndi kufanana pakati pa awiriwa. Kusankha yoyenera pamagetsi anu ndikofunikira kwambiri.

Kujambula kwa PCB

Iyi ndi njira yotetezera matabwa ozungulira podzaza mpanda ndi encapsulating resin kapena potting mankhwala. Chophatikizacho chimadzaza nyumba ya chipangizocho. Nthawi zina, gulu lonse la dera limaphimbidwa, kuphatikiza zigawo zonse. Pali nthawi zina pomwe mumangofunika zigawo za mphika zokha.

Pcb potting imapereka kukana kwakukulu kwa abrasion ndi chitetezo cha kutentha. Zimaperekanso chitetezo ku mankhwala ndi mitundu yonse ya zoopsa zachilengedwe.

Zosakaniza zabwino kwambiri za potting

Pali mitundu yosiyanasiyana ya miphika yomwe mungagwiritse ntchito. Zidazi zikuphatikizapo:

• Epoxy ndi chinthu chokhazikika komanso chodziwika bwino chomwe chimagwiritsidwa ntchito pa PCB. Amapereka mankhwala abwino kwambiri otsutsa komanso kumamatira. Lili ndi zinthu zambiri zofunika. Chimodzi mwazovuta zazikulu za nkhaniyi ndikuti zimatenga nthawi yayitali kuti zichiritsidwe ndikuziyika.
• Polyurethane: Ichi ndi poto chofewa chomwe chimakhala choyenera kwambiri. Ndi imodzi mwa njira zabwino kwambiri zotetezera zolumikizira ndi zida zamagetsi zomwe sizingagwire zida zolimba. Chimodzi mwazinthu zomwe zimadziwika bwino ndi kutentha kwake komanso kukana chinyezi. Ndiwopambana kwambiri poyerekeza ndi zida zina.
• Silicone: iyi, ndi yosinthika komanso yokhazikika yopangira miphika yomwe ingagwiritsidwe ntchito mosiyanasiyana. Imatha kupirira kutentha kwambiri. Ili ndi mtengo wokwera poyerekeza ndi zosankha zina, ndikupangitsa chisankho kukhala chosatheka nthawi zina.

Zothandiza za potting compounds

Mu electronic assembly, potting mankhwala ndi zofunika kwambiri. Amapereka chitetezo chokwanira mumitundu yonse. Amathandizanso mphamvu zamakina pomwe akuperekabe magetsi abwino kwambiri. Amagwiritsidwa ntchito m'mafakitale ambiri komanso mumagetsi ogula.

Iyi ndi njira yotetezera yomwe imatha kukhala yokhazikika ndipo imakhala gawo la gawoli pa moyo wake wonse. Pali zabwino zambiri zomwe zimagwirizanitsidwa ndi potting compounds, ndipo zimaphatikizapo izi:

• Kutchinjiriza kwamagetsi
• Kutentha kwanyumba
• Mphamvu zamakina zowonjezera
• Kugwedezeka ndi kukana kugwedezeka
• Kuteteza mankhwala
• Dzimbiri chitetezo
• Zokhudza chilengedwe

Pakusonkhanitsa ndi kupanga, zinthu za potting ndizofunikira kwambiri. Amathandiza kuthetsa mavuto osiyanasiyana. Mankhwalawa ndi abwino kwambiri popewa chinyezi. Amaonetsetsanso kuti palibe maulendo afupikitsa komanso chitetezo chamankhwala pamisonkhano yomwe imakhala yovuta kwambiri. Amafunika m'malo ndi zochitika zambiri, kuphatikizapo kubisa nzeru.

Ku DeepMaterial, tili ndi zinthu zambiri zopangira miphika. Mankhwalawa ndi osinthika komanso omveka bwino kuti athane ndi zovuta zosiyanasiyana zomwe zimapezeka muzochitika zosiyanasiyana. Kampaniyo imagwira ntchito kuti ikwaniritse zofunikira komanso zofunikira zamakasitomala osiyanasiyana.

Zogulitsazi sizinganyalanyazidwe. Iwo ndi gawo lofunikira la zamagetsi ndi ntchito zosiyanasiyana. Pochita zinthu moyenera, kukhulupirika kwa chipangizo chanu kapena kugwiritsa ntchito sikungasokonezedwe mwanjira iliyonse.
