Txhawm rau {{0 -247 phaj yog ib feem dav siv rau transistor lossis lub zog sliconductor pob. Nws muaj ntau yam siv hauv cov khoom hluav taws xob, feem ntau rau kev tswj hwm hluav taws xob thiab cua sov dissipation. Qhov rau {-247 Pad feem ntau yog txuas nrog sab hauv lub nroog semicondor, ua yeeb yam raws li lub tshuab cua sov kom tsis txhob muaj cov kev ua haujlwm. Nws yog feem ntau txuas nrog lub tshav kub sab nraud lossis cov khoom siv thermal interface (xws li thermal pads, roj, lossis tej hub dab dej) txhawm rau txhim kho kev ua kom sov. Nyob rau hauv ntau pab kiag li lawm, rau -247 yog sib txuas rau cov neeg sau (hauv ib lub bjt), ntws (hauv ib tug mosfet), lossis cathode (nyob rau hauv ib diode). Nws pabcuam ua ob qho tib si thermal thiab hluav taws xob coj, txo cov xaim thiab txhim kho kev ua tau zoo.
Dab tsi cov khoom siv ceramic siv rau -247} thermal ncoo?
Feem ntau cov ntaub ntawv coveramic siv rau -247 kub thermal ua hauj lwm, thiab rwb thaiv tsev hluav taws xob, thiab tsis kam rau siab kub. Cov ntaub ntawv sib koom ua ke rau cov phiaj xwm rhaub dej muaj:
Alumina Ceramic Phaj, nws yog qhov siab thermal conductivity (txawm hais tias qis dua aln thiab cov rwb thaiv tsev hluav taws xob, muaj zog thiab hluav taws xob ruaj khov. Alumina thermal ncoo rau -247 yog feem ntau yog siv rau cov dab dej dav dav hauv cov khoom siv hluav taws xob dav dav. Nws yog tus nqi tsim txiaj ntsig piv rau lwm yam ceramics.
Aluminium Nitride (Aln) coveram yog lwm txoj kev xaiv rau -247 pad. Nws muaj cov thermal zoo dua (mus txog {170-200 W / MIN}} W / min resistောင်း rwb thaiv tsev thiab kub tiv thaiv kom cua sov. Aln rau -247 p phaj feem ntau siv rau cov khoom siv hluav taws xob siab elctronics thiab cov ntawv thov thaum cov ntawv thov ua kom sov yog qhov tseem ceeb.
Silicon Nitride (Si3N4) Ceramic tseem tuaj yeem siv rau rau -247 phaj. Nws muaj cov thermal superial conductivity (txog li 80 · k), muaj zog muaj zog thiab muaj zog, thiab kev zam tsis kam mus rau cov cua sov thiab kev xav tsis thoob. Nws tau thov rau lub tshuab cua sov thaum thermal conductivity thiab thermal poob siab kuj yog ob qho ntsiab lus tseem ceeb.
