Ha lisebelisoa tsa elektroniki li ntse li le matla le ho kopana, ho chesa mocheso ka nepo ho bohlokoa bakeng sa ho netefatsa ts'epo, ts'ebetso le bophelo bo bolelele. Mona ke moo lisebelisoa tse tsoetseng pele tsa taolo ea mocheso, haholo-holo alloy ea koporo ea Tungsten le alloy ea koporo ea Molybdenum, li bonts'ang boleng ba tsona ba bohlokoa. Ka ho kopanya ka boqhetseke melemo ea litšepe tse refractory le koporo, metsoako ena e fetohile thepa e ka sebelisoang molemong oa{4}}molokong o latelang oa tharollo ea lisebelisoa tsa sink.
1. Lintho tsa Bohlokoa: Motheo oa Bokhabane
Tungsten Copper le Molybdenum Copper alloys ke metsoako ea phofo ea metallurgy. Ha se metsoako e bonolo empa e bōpiloe ka mekhoa e rarahaneng e kang ho kenella ka hare ho metsi, moo skeleton ea porous tungsten kapa molybdenum e tletseng koporo e qhibilihisitsoeng. Sena se etsa hore ho be le sete e ikhethang ea thepa e ka khonehang:
- Katoloso e Laolehang ea Thermal: Thermal Expansion Coefficient (CTE) e ka etsoa ka nepo ka ho lokisa tekanyo ea tšepe. Mohlala, letlapa la koporo la Tungsten le nang le 85%W-15%Cu le ka fumana CTE e tlase joalo ka 6.5 ppm/℃, e leng se lumellang hore ho be le kamano e haufi-ufi le lirafshoa tse kang Alumina kapa lisebelisoa tsa semiconductor tse kang GaAs. Sena se fokotsa khatello ea maikutlo 'me se thibela ho hloleha ha li-interfaces tse thata.
- High Thermal Conductivity: Karolo e tsoelang pele ea koporo ka har'a motsoako e fana ka tsela e babatsehang ea ho fetisa mocheso. Maemo a tloaelehileng a mocheso a tloha ho 160 ho isa ho 240 W/(m·K), e leng ho nolofalletsang mocheso o potlakileng ho tloha libakeng tse chesang.
- Matla a Ikhethileng a Mechini: Leha e na le koporo e ngata, masapo a tšepe a refractory a fana ka matla a makatsang le ho tiea ha mocheso o phahameng, o fetang koporo e hloekileng hole. Sena se tiisa botsitso ba dimensional tlasa baesekele e futhumetseng.
- Chate e latelang e bapisa likarolo tsa bohlokoa tsa li-alloys tsena le koporo e hloekileng, e totobatsang ho feto-fetoha ha tsona ho holimo:
2. Likereiti le Liforomo tsa Boitsebiso: Ho Kopana le Litlhoko tse fapaneng tsa Kopo
Li-alloys tsena li fumaneha ka mefuta e fapaneng ho fihlela litlhoko tse khethehileng tsa mocheso le mochini.
- Li-Alloys tsa Koporo tse Tloaelehileng tsa Tungsten: W70Cu30, W80Cu20, W85Cu15, W90Cu10. Lintho tse phahameng tsa tungsten li eketsa ho thatafala le ho theola CTE, ha koporo e phahameng e matlafatsa conductivity ea mocheso.
- Li-Alloys tsa Koporo tse Tloaelehileng tsa Molybdenum: Mo60Cu40, Mo70Cu30, Mo80Cu20, Mo85Cu15. Molybdenum koporo ka kakaretso e fana ka tekanyo e ntle ea machinability le ts'ebetso bakeng sa lits'ebetso tse ngata.
- Bakeng sa ho kopanngoa le tsamaiso ea mocheso, lisebelisoa tsena li fanoa ka mefuta e nepahetseng:
- Tungsten Copper Sheet/Plate: E sebelisoa e le li-spreaders kapa li-substrates tse tobileng tsa mocheso. Hangata li entsoe ka libopeho tse tloaelehileng ho lumellana le mekhoa e itseng ea mojule.
- Flanges le Submounts: Likarolo tsa bohlokoa ka har'a liphutheloana tsa laser diode le li-amplifiers tsa matla tsa RF, tse fanang ka taolo ea mocheso le ts'ehetso ea sebopeho.
- Likarolo tse Tloaelehileng tsa Mochini: Ho kenyeletsoa litsi tsa ho teba ha mocheso, lipoleiti tse tsamaisang thepa, le liforeimi tse loto, tse etselitsoeng likopano tse rarahaneng tsa elektroniki.
3. Libaka tsa Kopo tsa Bohlokoa
Matrix a thepa e ikhethang ea W-Cu le Mo-Cu alloys e li etsa hore e be tse loketseng tikoloho e batloang haholo ke mocheso:
- Microelectronics & Power Modules: E sebetsa e le li-Heat spreaders le substrates bakeng sa-iGBTs, CPUs, le GPUs tsa matla a holimo. Li fetisetsa mocheso ho tloha ho semiconductor dies ho ea ho lithabeng tse khōloanyane, tse pholileng{2}} tse pholileng.
- RF & Microwave Communications: Liteisheneng tsa motheo tsa 5G, litsamaiso tsa radar, le lisebelisoa tsa puisano tsa sathelaete, lisebelisoa tsena li sebelisetsoa lisinki tsa mocheso oa microwave, li-carrier flanges le likarolo tsa waveguide. Ba netefatsa botsitso ba matšoao le tlhahiso ea matla ka ho boloka li-chips tsa amplifier li pholile.
- Sefofane le Tšireletso: E sebelisoa ka har'a lisebelisoa tsa elektroniki bakeng sa lifofane, litsamaiso tsa tataiso, le radar ea moeeng, moo ho tšepahala ha maemo a feto-fetohang a mocheso{0}}ho sa rekisoeng.
- High{{0}Power Laser Diodes: E sebetsa joalo ka lithapo tse tlase le licheso tsa mocheso, li laola mocheso o matla oa lehae o hlahisoang ke li-junctions tsa laser, ho thibela ho hoholeha ha maqhubu le ho senyeha ha matla.
4. Ho Kopana le Mofani ea Tšeptjoang: Zhuzhou Kingdon
Ho khetha moetsi ea tšepahalang le ea nang le boiphihlelo ho bohlokoa joalo ka ho khetha boemo bo nepahetseng ba thepa. Zhuzhou Kingdon Industrial & Commercial Co., Ltd (W/Mo Ho tloha ka 2004) e hlahella e le setsebi se ka sehloohong sa lihlahisoa tsa tungsten le molybdenum.
Ka boitseanape ba lilemo tse ka bang mashome a mabeli, Kingdon e fana ka litharollo tse felletseng ho tloha ho ho hlophisoa ha lintho ho isa ho tse felileng, tse nepahetseng{0}}likarolo tsa mochini. Tlhahiso ea bona ea ka{{2}ka tlung ea phofo e netefatsa hore ho na le taolo e tiileng holim'a bohloeki ba lintho tse bonahalang, ho teteana, le ho homogeneity-lintho tse amang ts'ebetso ea mocheso le ts'epahalo ka kotloloho. Hore na morero oa hau o hloka letlapa le tloaelehileng la koporo la Tungsten kapa kopano e rarahaneng, e entsoeng ka brazed, Kingdon e fana ka tšehetso ea tekheniki le bokhabane bo hlokahalang bakeng sa katleho.
Bakeng sa tlhaiso-leseling e batsi kapa ho bua ka litlhoko tsa hau tsa taolo ea mocheso, ka kopo ikopanye le:

5. Qetello
Ka ts'ebetsong e sa khaotseng ea matla a maholo a matla le ho fokotsa matla a motlakase, litharollo tsa setso tsa mocheso li fihla moeling oa tsona. Tungsten koporo le li-alloys tsa koporo tsa Molybdenum li fana ka mefuta e meng e phahameng, e entsoeng ka boenjiniere. Bokhoni ba bona ba ho lokisetsoa litlhoko tse khethehileng tsa CTE le tsa conductivity, tse kopantsoeng le matla a phahameng le ho tšepahala ho netefalitsoeng, li li beha e le lisebelisoa tsa lejoe la sekhutlo bakeng sa tsamaiso e tsoetseng pele ea mocheso. Ho tloha motheong oa tora ea 5G ho ea botebong ba sebaka, likarolo tsena li thusa mahlale a kajeno le a hosane ka khutso ka ho rarolla e 'ngoe ea liqholotso tse phehellang tsa boenjiniere: ho boloka lintho li pholile tlas'a khatello.
