Dab tsi yog Potting Materials rau Electronics

Cov khoom siv potting yog cov kua resins uas daim pam ib lub rooj tsavxwm hauv ib txheej tiv thaiv, tiv thaiv cov khoom siv hluav taws xob hauv. Los ntawm dej mus rau cua sov, vibrating cuam tshuam thiab txawm tias tsuas yog lub qub qub Niam Xwm nws tus kheej - cov khoom siv no xav tau txhua yam kev tiv thaiv ntxiv uas lawv tuaj yeem tau txais! Txawm hais tias nws yuav zoo li overkill, potting yog ib qho tseem ceeb ntawm kev ua kom koj cov circuits muaj kev nyab xeeb.

Muaj peb hom potting khoom tawm muaj; txhua tus coj nws tus kheej tshwj xeeb perks thiab cons. Ntshiab li niaj hnub, koj yuav tau txais ib yam dab tsi txawv nyob ntawm seb cov khoom koj xaiv. Hauv tsab ntawv no, peb yuav saib ntau yam potting cov ntaub ntawv rau electronics nrog rau lawv qhov zoo thiab qhov tsis zoo.

Hom ntawm Cov khoom siv lauj kaub rau Electronics

 

Urethane thiab Epoxy

Potting electronics yuav tsum muaj kev tiv thaiv zoo tshaj plaws thiab fabricators paub tias tsis muaj cov ntaub ntawv zoo rau txoj haujlwm tshaj li epoxy thiab urethane. Rau qhov kub hnyiab 180 ° F, koj tau txais cov urethanes saib xyuas koj cov khoom me me, lossis yog tias qhov kub thiab txias yuav tsum tau ua - siab li 250 ° F - ces epoxies tsuas yog qhov koj xav tau!

Tau kawg, nws yog, muab kev tiv thaiv ntau yam nrog cov ntaub ntawv nyuaj-raws li-nails uas yuav tsis cia koj poob. Nws tsuas ua rau kev nkag siab xwb.

Epoxy thiab urethane muaj peev xwm sib khi muaj zog, ua rau lawv tsis muaj zog rau qhov muag uas xav rov ua dua cov khoom uas twb muaj lawm. Hauv lwm lo lus, cov nplaum no ua haujlwm zoo thaum koj xav tau los tiv thaiv koj lub tswv yim los ntawm lwm tus!

Cov ntaub ntawv no muaj ntau qhov zoo, tab sis kuj muaj qhov tsaus ntuj. Siv lub potting, piv txwv li; koj tsis tuaj yeem tshem nws tawm thaum nws teeb tsa, yog li yog tias muaj qee yam yuam kev, koj feem yog keeb kwm - tsis tau mus txog qhov ntawd. Nws yog txoj haujlwm nyuaj kawg nkaus, thiab tsis tuaj yeem ua ntau yam txog nws.

 

silicone

Silicone-formulated potting tebchaw muab ib qho array ntawm impressive zoo dua lwm yam ntaub ntawv, tshwj xeeb tshaj yog epoxies thiab urethanes. Yog li ntawd, cov kws tshaj lij hluav taws xob tau hloov mus rau silicone ntau dua li yav dhau los txhawm rau txhawm rau ua kom zoo dua ntawm nws cov yam ntxwv tshwj xeeb. Tias yog vim li cas nws thiaj li tawm los rau saum toj rau txhua qhov chaw hauv qab no!

• Kho Kho- Tshem tawm silicone yog ib qho yooj yim, cov ntaub ntawv nyuaj chemistry suav nrog. Yog li, koj tsis tas yuav txhawj xeeb txog kev puas tsuaj rau lub zog thiab kev ruaj ntseg yog tias muaj qee yam coj los rau koj lub rooj cob qhia - nws tuaj yeem kho tau!

 

• Kub Ntsuas- cov khoom siv epoxy thiab urethane tsis tu ncua siv rau lub rooj tsav xwm hauv Circuit Court xwb tsis tuaj yeem tuav cov cua sov, tab sis qhov ntawd yog qhov uas silicone tuaj yeem siv tau. Nws muaj lub peev xwm kub zoo los ntawm qhov txias qis ntawm -50 ° F mus rau qhov kub siab tshaj ntawm 400 ° F, yog li koj tuaj yeem suav rau nws qhov kev ua tau zoo txawm tias qhov kev sib tw zoo li cas los cuam tshuam koj txoj kev.

 

• UV Resistance- Nyob rau hauv tshav ntuj, cov khoom siv silicone tsis raug kev txom nyem los ntawm kev puas tsuaj rau lwm cov ntaub ntawv - tsis tawg! Qhov no yog vim lawv qhov kev tiv thaiv UV, uas tiv thaiv lawv hauv kev zam. Unsurprisingly, lawv tuaj yeem muab tso rau hauv ntau yam khoom siv thiab cov ntawv thov uas lub hnub ci ntev tsis tawm ntawm daim npav.

 

• Xim kub- Qhov no yog hais txog qhov tseem ceeb thaum xav txog LED teeb pom kev zoo. Tseem, cov xim tiav ntawm koj cov khoom tuaj yeem yooj yim distorted lossis txawm hloov tag nrho los ntawm cov khoom siv hauv kev teeb tsa kho vajtse. Yog li, ua tib zoo xav txog yam koj yuav mus nrog qhov ntawd! Los ntawm kev sib piv, silicone yog resistant rau yellowing thiab tuaj nyob rau hauv ib tug ntau yam ntawm optically meej daws. Yog li ntawd, koj tuaj yeem tso siab tau tias lub teeb pom kev zoo yuav tuav nws cov xim tiag tiag thaum lub sijhawm.

 

• Kev sib dhos yooj yim- Silicone potting txav nrog cov kua zoo li sib xws, ua rau nws yooj yim rau kev sib khi cov khoom tsis muaj txhua yam teeb meem uas lwm yam khoom xav tau. Qhov no ua rau koj muaj kev nyuaj siab thaum nws los txog rau potting!

 

• Tsis muaj Shrinkage- Epoxy thiab urethane yog qhov tsis zoo rau kev ntsws thaum lawv teeb tsa. Ntawm qhov tod tes, silicone, tsis tshua muaj temperamental, zoo li shrinkage-dawb thaum nws kho, yog li tsis xav tau cov kauj ruam ntxiv! Qhov no txhais tau tias koj nyuam qhuav tau txais koj tus kheej lub sijhawm txuag nyob ntawd.

 

• Noj Qab Haus Huv -Nrog rau cov khoom siv potting siv, kev nyab xeeb thiab kev noj qab haus huv ntawm cov neeg ua haujlwm yog nyob ntawm ceg txheem ntseeg! Silicone muaj kev nyab xeeb dua rau cov neeg siv nws, yog li cov kws tsim khoom siv cov khoom siv no thaum lawv xav tau los cuam tshuam cov teeb meem nrog kev ua haujlwm ua haujlwm. Yog tias kev noj qab haus huv thiab kev nyab xeeb yog qhov tseem ceeb - uas lawv feem ntau yog! - Tom qab ntawd muaj cov khoom lag luam uas ua rau cov neeg ua haujlwm zoo tshaj plaws yog qhov tseem ceeb tshaj plaws. Yog vim li cas silicone tig mus rau hauv tons ntawm cov cuab yeej kho mob tawm muaj; cov txiaj ntsig tsis tuaj yeem tsis quav ntsej.

 

• adhesion- Ua hauj lwm nrog silicone muaj ib tug downside: qee hom encapsulants xav tau ib tug primer rau sticking - uas epoxy thiab urethane tsis xav tau. Uas tau hais tias, qhov no kuj tuaj yeem yog ib qho ntxiv rau qee zaum vim qhov sib zog adhesion tso cai rau koj los kho koj cov khoom hauv txoj hauv kev uas lwm cov tebchaw tiv thaiv.

 

Xaiv Txoj Cai Potting Khoom rau Electronics

Xav txog cov khoom siv potting zoo tshaj plaws rau koj daim ntawv thov? Koj yuav tsum tau coj qee yam rau hauv tus account ua ntej daws ib qho. Xav txog cov yam ntxwv tseem ceeb no koj yuav tsum saib xyuas thaum koj txiav txim siab- lawv tuaj yeem qhia cov nplai hauv kev nyiam ntawm ib yam khoom!

 

• Hardness: Nws tsis pub leejtwg paub tias hardness feem ntau yog ib qho kev txiav txim siab thaum xav txog cov kev siv sib txawv. Txawm hais tias cov khoom hnyav dua muab kev tiv thaiv ntxiv tiv thaiv kev puas tsuaj, ib puag ncig thiab kev cuam tshuam IP, qee yam softer feem ntau tuaj yeem ua rau kev kho dua tshiab. Siv epoxy thiab urethane, piv txwv li; lawv cov hardness ranges ntawm 80 D nyob rau sab saum toj kawg nkaus kom tsawg li 10A nyob rau hauv qab - tag nrho raws li lawv tus kheej durometer scale. Tab sis thaum nws los txog rau lub sijhawm los daws cov gel silicones, peb hloov khoom thiab pib ntsuas kev nkag mus xwb!

 

• Viscosity- Nrog lawv cov viscosity tsawg, feem ntau ntawm cov potting tebchaw tuaj yeem ntws dawb thiab nyob rau theem ntuj thaum teeb tsa. Txawm li cas los xij, qee zaus, koj xav tau kev tswj xyuas ntau dua qhov twg cov resin ntws mus rau, rau qhov twg cov khoom siv viscosity ntau dua los ua ke!

 

• Thermal Tus Cwj Pwm- Tus yeeb ncuab thib ib hauv cov khoom siv hluav taws xob siab? Nws yog qhov yooj yim: cua sov. Txhawm rau muab cov tsiaj nyaum no rau khau raj, xaiv cov tshuaj potting kom zoo yog qhov tseem ceeb. Xaiv cov silicones yog tias koj xav tau ib yam dab tsi txawv tshaj plaw ntawm kev ua lub zog thermal kom deb ntawm cov khoom kub. Feem ntau tsis yog, lawv ua lawv txoj haujlwm zoo kawg nkaus, tab sis cov epoxy lossis urethane compounds tuaj yeem sau rau hauv cov subs txaus thaum xav tau. Muaj txawm tias qee qhov sib xyaw tshwj xeeb nrog cov khoom tshwj xeeb los kho cov kev coj ua thiab txiav nws rau kev siv tshwj xeeb!

kawg

Xaiv qhov sib xyaw potting kom raug tuaj yeem ua rau txhua qhov sib txawv thaum tsim cov khoom zoo. Siv cov khoom siv potting tsim nyog rau txhua daim ntawv thov pab cov neeg tsim khoom siv ntau txoj hauv kev thaum tau txais cov txiaj ntsig saum toj kawg nkaus. Yog li, nco ntsoov tias ua cov kauj ruam me me no rau kev ua tiav tsis yog qhov ci ntsa iab xwb - lawv yog qhov tseem ceeb.
