Intshayelelo
Njengoko ishishini lombane liqhubeka nokutyhala imida yoxinaniso lwamandla kunye ne-miniaturization, umceli mngeni wolawulo lwe-thermal uye waba yinto ebalulekileyo ekuqinisekiseni ukuthembeka nokusebenza kwesixhobo. Ukutshatyalaliswa kokushisa okusebenzayo kubaluleke kakhulu ukukhusela ukusilela kwecandelo kunye nokugcina uzinzo lokusebenza. Kulo mxholo,tungsten ubhedu sheetivelile njengesisombululo esiphambili-sokusebenza okuphezulu kokupakishwa kwe-elektroniki. Njengomxube wesinyithi we-matrix, idibanisa ngokukodwa ukwandiswa kwe-thermal ephantsi ye-tungsten kunye ne-thermal conductivity ephezulu yobhedu, iyenza ibe yimathiriyeli efanelekileyo yokutshiza ubushushu, abathwali be-chip, kunye neepleyiti zokunyusela ezishushu kwizixhobo zombane eziphezulu{2}ezinamandla.
I-Advanteji yezinto eziphathekayo yeTungsten Copper
Ukusebenza kobhedu lwe-tungsten njenge-izinto zokupakisha ze-elektronikiilele kwiimpawu zayo ezingaqhelekanga. I-coefficient yemathiriyeli yokwandiswa kwe-thermal (CTE) ingalungelelaniswa ngokuchanekileyo ngokutshintsha i-tungsten-ukuya{2}}kumlinganiselo wobhedu, ukuyivumela ihambelane nemathiriyeli eqhelekileyo yesemiconductor efana nesilicon, i-gallium arsenide, kunye neeseramikhi ezifana ne-aluminiyam oxide (Al₂Oluminiyam₃). Lo mdlalo we-CTE ubalulekile ekwehliseni uxinzelelo lwe-thermal kunye nokuthintela ukubola okanye ukuqhekeka kwi-chip{4}}ujongano lwe-substrate ngexesha lokuhamba ngebhayisekile.
Ngaxeshanye, isigaba sobhedu sibonelela ngendlela yokuqhuba ubushushu obukhawulezayo, kunye nexabiso le-thermal conductivity lifikelela kwi-200-340 W / (m·K) ngokuxhomekeke kwibakala elithile. Olu kudibanisa luqinisekisa ukuba ukushisa okwenziwa yi-junction ye-semiconductor kusasazeka ngokufanelekileyo kwaye kuchithwa, ngaloo ndlela kugcinwe isixhobo ngaphakathi komgangatho wokushisa okhuselekileyo wokusebenza. I-hermeticity egqwesileyo yemathiriyeli kunye nokuchaneka kukwavumela ukwenziwa okuchanekileyo kwiimilo ezintsonkothileyo, eziyimfuneko kwindibano yanamhlanje ye-elektroniki.
Isicelo kwi-Electronic Packaging
Ukuziqhelanisa, amaphepha obhedu e-tungsten asetyenziswa kakhulu kwiipleyiti zokufakelwa kwe-thermal, iiflange, kunye nezakhelo apho zombini ukutshatyalaliswa kobushushu kunye nokunyaniseka kwesakhiwo kuyadingeka. Imathiriyeli ifaneleke ngokukodwa izixhobo eziphezulu-eziphezulu zemicrowave, iimodyuli ze-IGBT, kunye nelaser diode apho ubushushu bobushushu buphezulu kakhulu . Ukukwazi ukulungelelanisa ukubunjwa, okufana ne-W-15Cu okanye i-W-20Cu, ivumela iinjineli ukuba zikhulise ibhalansi phakathi kokwandiswa kwe-thermal kunye ne-conductivity yezicelo ezithile.
Zhuzhou Kingdon Industrial & Commercial Co., Ltd.
Kumashishini afuna{0}umgangatho ophezulu wezinto zobhedu ze-tungsten,Zhuzhou Kingdon Industrial & Commercial Co., Ltd.ubalasele njengomthengisi othembekileyo. Ngokusekwe kwiphondo laseHunan, inkampani igxile ekuboneleleni ngoluhlu olubanzi lweemveliso zobhedu ze-tungsten, kubandakanya amashiti, iipleyiti kunye neentonga.

Bagxininisa imilinganiselo engqongqo yolawulo lomgangatho, efana ne-porosity ephantsi kunye ne-hermeticity ephezulu, kwaye banokubonelela ngesiqingatha{9}}imveliso egqityiweyo okanye egqityiweyo ngomatshini ochanekileyo kunye nocwecwe lomphezulu (umz., Ni/Au) ukuhlangabezana neemfuno ezithile zoshishino lwe-elektroniki.
Ukuqukumbela
Indima yetungsten ubhedu sheetkwizinto zombane zanamhlanje ziyimfuneko. Isakhono saso esisodwa sokudibanisa iipropathi ezihambelanayo ze-tungsten kunye nobhedu zenza ukuba ibe yimathiriyeli ekhethwayo kulawulo lwe-thermal kwiipakethe eziphezulu{1}}zokusebenza. Ngendima yayo ebalulekileyo ekwenzeni izixhobo zombane ezixineneyo nezinamandla, imfuno yesi sixhobo sobuxhakaxhaka sisetyenzisiweyo sikhule. Abavelisi bayathandaZhuzhou Kingdon Industrial & Commercial Co., Ltd.bangamaqabane abalulekileyo kweli candelo, beqinisekisa ubonelelo oluthembekileyo lomgangatho{0}ophezuluizinto zokupakisha ze-elektronikiezihlangabezana neemfuno ezingqongqo zeshishini .
