Potting Khoom Rau Electronics Thiab Yuav Ua Li Cas Xaiv Qhov Zoo Tshaj

Potting tuaj yeem txhais tau tias yog txheej txheem ntawm kev sau cov khoom siv hluav taws xob nrog cov khoom siv los txhim kho nws cov qib tsis kam. Nws tseem hu ua embedment thiab ua rau cov khoom thiab cov khoom sib dhos tiv thaiv kev vibrations, shocks, corrosive agents, tshuaj, dej, thiab txawm tias ya raws thiab cua sov. Lub thawv potting, feem ntau yog ib lub hnab yas me me, yog siv los tsim cov khoom siv hauv tsev, xws li PCB, thiab cov resin hauv cov kua ua kua yog ntim thiab tso cai rau kho. Lub thawv kuj tseem tuaj yeem yog kab noj hniav nyob rau hauv ib lub qhov rooj loj rau kev tiv thaiv tshwj xeeb ntawm cov rooj sib txoos tshwj xeeb lossis cov rooj sib tham hauv cheeb tsam.

Cov khoom siv hluav taws xob xws li cov ntawv luam tawm hluav taws xob tau nce kev tiv thaiv los ntawm hluav taws xob xau, ya raws, thiab lwm yam kev phom sij uas tuaj yeem ua rau lawv puas tsuaj. Txhim kho kev ua tau zoo ntawm cov khoom siv hluav taws xob thiab kev txhim khu kev qha Circuit Court yog qee qhov zoo uas koj yuav tau txais thaum koj lub lauj kaub.

Cov txheej txheem kuj tseem pab kom muaj kev vibration thiab kev poob siab tsawg heev. Cov kev cuam tshuam zoo li no tuaj yeem ua rau cov khoom siv hluav taws xob ua haujlwm tsis zoo vim nws cuam tshuam nrog kev xaim thiab kev sib txuas. Kev vibration nthwv dej ntawm cov rooj sib tham hauv Circuit Court thiab lawv cov rooj plaub kuj tseem ua rau muaj kev ntxhov siab ua rau cov khoom siv hluav taws xob tsis ua haujlwm ntxov. Thaum koj lauj kaub, yog li ntawd, koj ua kom lub cuab yeej lifespan kom deb li deb raws li nws yuav tiv thaiv kev co thiab kev poob siab.

Potted electronics kuj muaj kev tiv thaiv los ntawm cov av thiab hmoov av, uas tuaj yeem ua rau overheating, yog li cuam tshuam rau kev ceev, kev ua tau zoo, thiab cov teeb liab ntawm cov khoom siv hluav taws xob. Epoxy, urethane, thiab silicone yog cov ntaub ntawv tseem ceeb siv hauv potting. Los ntawm saib cov yam ntxwv thiab cov khoom ntawm txhua tus, koj yuav tsum muaj peev xwm txiav txim siab qhov twg potting khoom rau electronics yog qhov zoo tshaj plaws. Qhov xwm zoo yog koj yuav nrhiav tau ib yam khoom uas zoo tshaj plaws rau koj daim ntawv thov.

Epoxy potting compounds

Raws li cov potting compound, epoxy muaj cov adhesion zoo thiab yog li tiv thaiv cov khoom siv hluav taws xob ntev. Qhov no yog cov khoom siv uas ua haujlwm ntawm nws tus kheej yam tsis tas yuav ntxiv primers thaum potting electronics. Lub zog tensile siab, modulus, thiab rigidity ua rau nws yog ib qho kev xaiv zoo tshaj plaws rau cov khoom siv hluav taws xob feem ntau, tshwj xeeb tshaj yog rau kev siv sab nraum zoov xws li cov khoom siv ua liaj ua teb, transformers, thiab keyboards.

Urethane potting compounds 

Raws li ib tug potting compound, qhov elongation, yoog raws, thiab kev puas tsuaj ua rau nws yog qhov kev xaiv zoo, tshwj xeeb tshaj yog rau cov khoom tseem ceeb uas yuav tsum tau ua kom muag muag. Cov khoom siv uas muaj cov substrates xws li iav, yas, ceramics, thiab hlau alloys yuav nyiam urethane ua cov khoom siv potting.

Silicone potting compounds

Raws li kev sib xyaw potting, silicone qhov hloov tau ua rau nws zoo heev rau qee yam khoom siv. Nws muaj cov khoom zoo elongation thiab yog mos thiab yoog raws. Silicone tseem ua haujlwm kub ntau thiab ua rau muaj kev ntxhov siab tsawg dua ntawm cov khoom siv hluav taws xob piv nrog epoxy.

Thaum xaiv cov khoom siv potting zoo tshaj plaws rau koj cov khoom siv hluav taws xob, koj yuav tsum xav txog cov hauv qab no:

Cov khoom hardness. Epoxy thiab urethane tebchaw muab qhov zoo tshaj plaws IP tiv thaiv, huab cua, thiab abrasion tsis kam vim lawv nyuaj thaum lawv kho. Silicone kuj yog ib qho nyuaj tab sis yoog raws thiab tsis nruj li epoxy. Xav txog seb qhov hardness haum rau koj cov khoom siv hluav taws xob thiab xaiv raws li.

Khoom siv viscosity. Tsawg viscosity siv rau feem ntau daim ntaub ntawv vim hais tias cov ntaub ntawv potting yog tus kheej-leveling thiab ntws yooj yim raws li xav tau. Txawm li cas los xij, koj tuaj yeem xaiv cov ntaub ntawv nrog cov viscosity siab dua yog tias koj daim ntawv thov yuav tsum tau hais tseg.

Khoom xim. Clear potting compounds muab visibility txawm tias tom qab kho thiab zoo rau cov khoom tseem ceeb uas yuav tsum tau kuaj xyuas tsis tu ncua. Cov xim opaque tsaus yog qhov ua tau zoo hauv lwm daim ntawv thov, thiab koj yuav tsum xaiv cov xim uas zoo sib xws nrog cov khoom siv hluav taws xob.

Thermal conductivity. Potting tebchaw nrog siab thermal conductivity yooj yim dissipate tshav kub hluav taws xob khoom tsim. Tag nrho peb cov khoom siv potting loj yog qhov zoo hauv qhov no, tab sis silicone siv lub yas.
