15W Ceramic Case

15W ceramic rooj plaub yog qhov tseeb -cov khoom ntim khoom tsim kho rau nruab nrab - cov khoom siv hluav taws xob tsawg tsawg - suav nrog cov cuab yeej siv hluav taws xob lub cev muaj zog, cov khoom siv hluav taws xob me me, thiab cov cuab yeej siv kho mob - uas xav tau kev tswj xyuas kom sov thiab ua haujlwm hnyav. Tsis zoo li qis dua -qib ceramic cov ntaub ntawv, nws yog tsim los ntawm 99% siab- purity alumina ceramic, ib yam khoom uas tau xaiv rau nws ultra- thermal expansion coefficient (7.1 × 10⁻⁶ / degree){12}} ib qho tseem ceeb feature uas phim cov thermal zog ntawm semiconductor chips (xws li siliconductor chips). arsenide). Qhov kev sib raug zoo no txo ​​qis kev ntxhov siab thaum lub caij kub (xws li, thaum lub tshuab hluav taws xob qhib / tawm ntau zaus), tiv thaiv cov kab nrib pleb hauv nti - mus rau - rooj plaub interface thiab txuas ntxiv lub neej ntawm cov khoom.

Cov txheej txheem tsim khoom ntawm 15W ceramic rooj plaub yog qhov ua kom zoo: nws pib nrog siab -purity alumina hmoov tov nrog cov organic binders, tom qab ntawd txhaj molding rau hauv cov duab nyuaj (xws li kev sib xyaw ua kom sov los yog mounting tabs rau kev sib dhos yooj yim), ua raws li debinding kom tshem tawm cov khoom siv organic, thiab thaum kawg sintering ntawm 1750℃density ntau dua li cov qauv . g/cm³). Tshaj tawm -sintering, nws dhau los ua qhov tseeb lapping kom ntseeg tau tias flatness (tsawg dua lossis sib npaug li 0.02 hli ib 100mm) thiab metalization (ntawm sputtering lossis screen printing) rau kev sib txuas hluav taws xob- kom ntseeg tau tias tsis muaj kev sib cuag (<5 mΩ) with circuit boards.
