I-Silicon Nitride Ceramic PCB | I-Substrate Yamandla Aphezulu Yamamojula Amandla

Isingeniso

I-PCB ye-silicon nitride ceramic imele intuthuko enkulu kwezobuchwepheshe be-substrate yezinhlelo ze-elekthronikhi ezinamandla aphezulu. Njengoba ubuningi bamandla buqhubeka nokwanda ezimotweni zikagesi, ezimotweni zezimboni, kanye nasezisetshenzisweni zamandla avuselelekayo, izidingo ezibekwe ezintweni zebhodi lesifunda ziye zanda kakhulu. Izisekelo ze-silicon nitride (Si₃N₄) ceramic zibhekana nalezi zinselele ngokusebenzisa ukuhanjiswa kokushisa okumangalisayo, amandla omshini, kanye nokuqina kokushisa, okuvumela ukuphathwa kokushisa okuphumelelayo kwamamojula kagesi esizukulwane esilandelayo kanye nama-inverter ezimoto.

Iyini i-Silicon Nitride Ceramic PCB?

Ama-substrates e-PCB e-Silicon nitride ceramic akhiwe nge-silicon nitride, i-ceramic material ethuthukisiwe enesakhiwo se-crystalline esihlinzeka ngezakhiwo ezihlukile zemishini nezokushisa. Izinto ezisetshenziswayo zikhiqizwa ngomshini wokucindezela oshisayo noma ngezinqubo zokucindezela igesi ezenza i-substrate eminyene, iyunifomu ene-porosity encane, okuholela ekuphatheni okushisayo okusuka ku-70 kuya ku-90 W/m·K ukuze kukhishwe ukushisa okusebenzayo kusuka kumadivayisi we-semiconductor yamandla.

I-substrate ngokuvamile ihlanganisa i-copper circuitry eboshwe nge-Direct Bonded Copper (DBC) noma amasu we-Active Metal Brazing (AMB). Lezi zindlela ze-metallization zakha isibopho esiqinile se-metallurgical phakathi kongqimba lwethusi kanye ne-ceramic substrate ngaphandle kokudinga izinto zokunamathisela eziphakathi nendawo, ukugcina izakhiwo zokufakelwa kukagesi ngenkathi zinikeza izindlela eziphansi zokumelana nokushisa kokususwa kokushisa ezingxenyeni ezibucayi.

I-Silicon Nitride Ceramic PCB vs. Traditional Ceramic Substrates

Uma ihlolwa ngokuqhathaniswa nama-substrates e-ceramic evamile, izinto ze-silicon nitride ceramic PCB zibonisa izici zokusebenza ezihlukile ezizenza zifanelekele izinhlelo zokusebenza zamandla kagesi ezifunwayo.
