Potting compounds yog cov ntaub ntawv tseem ceeb los tiv thaiv cov khoom siv hluav taws xob los ntawm ib puag ncig kev ntxhov siab, kev poob siab, thiab hluav taws xob tsis ua haujlwm. Hauv cov khoom siv hluav taws xob niaj hnub no, kev ua tiav ntev - lub sij hawm kev cia siab yuav tsum xaiv cov khoom siv potting zoo uas sib npaug ntawm kev tswj xyuas thermal, hluav taws xob rwb thaiv tsev, thiab cov khoom siv dej tsis zoo.
Epoxy, polyurethane (PU), thiab silicone -raws li potting compounds yog cov kev xaiv uas feem ntau siv. Epoxy potting compounds muab cov khoom siv zoo heev, adhesion, thiab thermal conductivity, ua rau lawv haum rau siab -kev ua haujlwm PCBA daim ntawv thov qhov kev nruj thiab kav ntev yog qhov tseem ceeb. PU potting compounds muab kev yooj yim, cuam tshuam tsis kam, thiab tiv thaiv ya raws, uas yog qhov zoo tagnrho rau cov khoom siv hnav lossis cov ntawv thov raug kev co. Silicone potting compounds, lub sijhawm no, ua tau zoo nyob rau hauv siab - qhov kub thiab txias ib puag ncig vim lawv cov thermal stability thiab hluav taws xob rwb thaiv tsev muaj peev xwm, feem ntau siv hauv automotive electronics thiab LED modules.
Cov yam tseem ceeb hauv kev xaiv cov potting compound muaj xws li viscosity, curing lub sij hawm, thermal conductivity, dielectric zog, thiab dej nqus. Tsawg- cov ntaub ntawv viscosity ua kom muaj kev tiv thaiv zoo dua thiab nkag mus rau hauv cov khoom siv hluav taws xob nyuaj, thaum cov thermal conductivity siab pab kom cov cua sov los ntawm cov khoom rhiab heev. Cov neeg tsim qauv tseem yuav tsum xav txog cov txheej txheem kho: qee cov ntaub ntawv kho tau ntawm chav tsev kub, thaum lwm tus xav tau kom sov siab lossis UV raug.
Kev siv cov khoom siv hauv potting tebchaw muaj xws li waterproofing sensors, encapsulating PCBA modules nyob rau hauv automotive electronics, thiab tiv thaiv LED teeb pom kev zoo los ntawm noo noo thiab mechanical stress. Piv txwv li, thermally conductive silicone potting tuaj yeem tiv thaiv overheating nyob rau hauv lub hwj chim modules, thaum hloov tau yooj yim PU potting absorbs vibrations nyob rau hauv wearable los yog portable li.
Thaum siv cov tshuaj potting, cov tuam txhab tsim khoom yuav tsum xyuas kom meej qhov kev npaj zoo, qhov sib xyaw kom raug, thiab tswj kev kho kom tsis txhob muaj qhov khoob, npuas, lossis tsis tiav adhesion. Kev tuav kom raug thiab khaws cia cov ntaub ntawv potting tseem ua lub luag haujlwm tseem ceeb hauv kev tswj hwm lawv cov kev ua tau zoo dhau sijhawm.
