I-conductivity egqwesileyo ye-thermal, i-coefficient elawulwayo yokwandiswa kwe-thermal kunye nokucoceka kwezinto ezibalaseleyo.Icace ngokugqibeleleyo: Iimveliso zethu zeshishini lombane zineempawu ezikhethekileyo zomzimba.Isetyenziswe njengamacwecwe esiseko kunye nokusabalalisa ukushisa, baqinisekisa ukuthembeka kwezixhobo zombane.

Ekuqaleni, into yokuba izinto zombane zivelisa ubushushu aziyi kuba yinto enokukhathazeka ngayo.Kule mihla, phantse nawuphi na umntwana wesikolo unokukuxelela ukuba iinxalenye zekhompyuter ziyafudumala ngelixa ilayitiwe.Ngelixa isixhobo sisasebenza, inxalenye yamandla ombane anikezelweyo ayalahleka njengobushushu.Kodwa makhe sijonge ngakumbi: Ukudluliselwa kobushushu kunokubonakaliswa njengokutshintsha kobushushu ngeyunithi (ye) yendawo (ubuninzi bobushushu bobushushu).Njengoko imizekelo ekwigrafu ibonisa, ukuxinana kobushushu kwizinto ezininzi ze-elektroniki bunokuba bugqithise.Uphakamile njengakwirokethi yomqala apho amaqondo obushushu afikelela kuma-2 800 °C anokuthi avele.

I-coefficient yokwandiswa kwe-thermal yenye into ebalulekileyo kuzo zonke i-semiconductors.Ukuba i-semiconductor kunye nesiseko sepleyiti imathiriyeli yanda kwaye ikhontrakthi ngamaqondo ahlukeneyo xa ibonakaliswe kutshintsho kwiqondo lokushisa emva koko uxinzelelo lomatshini luvela.Ezi zingonakalisa i-semiconductor okanye zonakalise uxhulumaniso phakathi kwe-chip kunye ne-heater spreader.Nangona kunjalo, ngezinto zethu, uyazi ukuba usezandleni ezikhuselekileyo.Imathiriyeli yethu ineyona coefficient ilungileyo yokwandiswa kwe-thermal yokujoyina i-semiconductors kunye neekeramics.

Njengamacwecwe esiseko se-semiconductor, umzekelo, izinto zethu zisetyenziswa kwii-injini zomoya, oololiwe kunye nokusetyenziswa kwezoshishino.Kwiimodyuli ze-semiconductor zamandla ze-inverters (thyristors) kunye ne-diode zamandla, zidlala indima ebalulekileyo.Ngoba?Enkosi kowona mlinganiso mkhulu wokwandiswa kwe-thermal kunye ne-thermal conductivity egqwesileyo, iipleyiti zesiseko se-semiconductor zenza isiseko esomeleleyo se-silicon semiconductor enovakalelo kunye nokuqinisekisa ubomi benkonzo yemodyuli ngaphezulu kweminyaka engama-30.

Izisasazo zokushisa kunye neeplati ezisezantsi ezenziwe kwi-molybdenum, i-tungsten, i-MoCu, i-WCu, i-Cu-Mo-Cu kunye ne-Cu-MoCu-Cu i-laminates ichitha ngokuthembekileyo ukushisa okwenziwa kumacandelo ombane.Oku zombini kuthintela ukufudumeza kwezixhobo zombane kwaye kwandisa ubomi bemveliso.Abasasazeki bethu bokushisa bancedisa ukugcina indawo epholileyo, umzekelo, kwiimodyuli ze-IGBT, iiphakheji zeRF okanye ii-chips ze-LED.Siye saphuhlisa izinto ezidityanisiweyo ze-MoCu ezikhethekileyo kwiipleyiti ezithwala kwiitshiphusi ze-LED.Oku kunomlinganiso wokwandiswa kwe-thermal efana nesafire kunye neekeramics.

Sinikezela ngeemveliso zethu kwishishini le-elektroniki ngeentlobo ezahlukeneyo zokugquma.Zikhusela izinto ezichasene ne-corrosion kwaye ziphucula uxhulumaniso lwe-solder phakathi kwe-semiconductor kunye nezinto zethu.
