Qhov xav tau ntawm cov nplaum nplaum rau potting electronics

Potting yuav sau ua tiav siv cov nplaum los yog potting compound. Thaum qhov no ua tiav, cov khoom feem ntau yog nyob rau hauv qhov chaw so lossis tsev nyob uas yuav tsum tau ntim nrog cov nplaum.

Vim li cas thiaj xav tau

Circuit boards muaj ob peb yam me me uas rhiab heev. Cov no suav nrog diodes, transistors, thiab microchips. Nws yog ib qho yuav tsum tau tiv thaiv lawv los ntawm ya raws uas ua rau luv luv Circuit Court. Yuav tsum muaj tshuaj tiv thaiv ib yam nkaus, vim nws tuaj yeem tawm tsam lossis ua rau cov khoom tawg. Kev cuam tshuam, kev vibration, thiab thermal shock kuj yuav tsum tau tiv thaiv. Qhov no yog vim tias lawv tuaj yeem tshem tawm cov khoom siv los ua cov cuab yeej lossis daim ntawv thov tsis muaj txiaj ntsig.

Muaj ntau qhov xwm txheej uas potting electronics ua rau nws nyuaj rau luam los yog soj ntsuam ntawm lub circuitry. Qhov no ua rau cov neeg nyeem daim npav thiab cov chips ntse nyuaj rau cov neeg ua txhaum cai nkag mus thiab cuam tshuam nrog. Qhov no yog tshwj xeeb tshaj yog thaum lub potting dhau los ua ib feem ntawm cov khoom siv thiab tsis tuaj yeem raug tshem tawm yam tsis muaj kev puas tsuaj rau lub tshuab.

Adhesives siv

Thaum potting nyob rau hauv ntau daim ntaub ntawv, nws yog ib txwm zoo dua los siv tsawg-viscosity adhesives. Lawv yog cov nyiam xaiv. Qhov no yog vim hais tias lawv sau cov khoom zoo dua thaum txo cov npuas npuas entrapment.

Hloov kho epoxies thiab ob feem epoxies yog qee qhov kev xaiv zoo tshaj plaws. Silicones thiab polyurethane kuj yog kev xaiv zoo. Muaj UV nplaum uas tuaj yeem siv los qhib kev kho sai, thiab lawv tsis xav tau kev sib xyaw. Cov duab ntxoov ntxoo, nrog rau qhov tob txwv, feem ntau qhia tias lawv yuav tsis haum. Txawm li cas los xij, qee qhov UV nplaum muaj cov txheej txheem kho mob thib ob uas tso cai rau kev kho tag nrho, txawm tias nyob hauv thaj chaw ntxoov ntxoo.

xav txog kev teem

Thaum koj xaiv cov nplaum los siv rau potting, muaj ntau qhov kev txiav txim siab los ua. Cov no suav nrog:

• Lub ntim ntawm lub receptacle: yog tias koj xav tau ntim loj, koj yuav tsum xav txog qhov exotherm ntawm cov nplaum thaum nws kho. Nws yog qhov zoo dua los xaiv cov nplaum nplaum qeeb vim tias lawv muaj feem tsawg dua ntawm cov cua sov thaum lawv kho.
• Flow thiab viscosity yam ntxwv: koj yuav tsum txiav txim siab seb lub potting puas tuaj yeem ntws raws li nws yuav tsum tau coated lub tinest thiab feem ntau intricate Cheebtsam. Koj kuj yuav tsum tau txiav txim siab seb koj puas tuaj yeem tiv thaiv huab cua nkag thiab cua npuas.
• Koj yuav tsum txiav txim siab seb yuav kho sai npaum li cas. Qhov no yuav pab koj txiav txim siab hom kev sib xyaw siv
• Cov khoom siv substrate siv los ua cov khoom siv yuav tsum tau txiav txim siab thiab. Nws yog ib qho tseem ceeb los xyuas kom meej qhov zoo tshaj plaws adhesion rau cov npoo.
• Daim ntawv thov txheej txheem yuav tsum tau txiav txim siab thiab. Koj yuav tsum xav txog seb nws yuav ua li cas manually lossis txiav. Tsis tas li ntawd, saib rau qhov zoo tshaj plaws ntawm kev siv cov khoom siv ob.
• Tsis tas li, txiav txim siab xim lossis opaqueness ntawm cov nplaum raws li xav tau. Muaj cov xwm txheej uas koj xav tau cov txiaj ntsig pom tseeb, thaum nyob hauv lwm tus, qhov sib xyaw opaque yog qhov zoo tshaj plaws.
• Adhesive hardness yog qhov tseem ceeb vim nws txo qhov kev pheej hmoo ntawm kev cuam tshuam. Qhov no txhais tau tias tsis tshua muaj kev ntxhov siab ntawm cov khoom hauv thermal contraction thiab expansion.
• Tus nqi yuav tsum tau txiav txim siab. Nws tsis yog ib txwm zoo los xaiv qhov kev xaiv pheej yig tshaj. Nrhiav ib yam dab tsi zoo thiab muaj peev xwm ua haujlwm ntawm tes.

Ntawm DeepMaterial, peb muaj qhov zoo tshaj plaws potting nplaum rau koj kom peruse. Nrog rau lub tswv yim zoo, koj yuav tsum tau txais cov txiaj ntsig zoo tshaj plaws nyob rau hnub kawg. Ua haujlwm nrog qhov zoo tshaj plaws muab sijhawm zoo rau koj kom tau txais cov kev daws teeb meem ruaj khov.
