Ts'ebetso e ntle ea mocheso oa mocheso, coefficient e laoloang ea katoloso ea mocheso le bohloeki bo ikhethang ba lintho tse bonahalang. E hlakile hantle: Lihlahisoa tsa rona tsa indasteri ea lisebelisoa tsa elektroniki li na le thepa e ikhethang ea 'mele. E sebelisoa e le lipoleiti tsa motheo le li-spreaders tsa mocheso, li netefatsa ho tšepahala ha lisebelisoa tsa motlakase.

Ha u sheba ka lekhetlo la pele, taba ea hore likarolo tsa motlakase li hlahisa mocheso e ke ke ea bonahala e le ntho e tšoenyang. Matsatsing ana, hoo e ka bang ngoana leha e le ofe oa sekolo a ka u bolella hore likarolo tsa k'homphieutha lia futhumala ha li ntse li buloa. Ha sesebelisoa se ntse se sebetsa, karolo ea matla a motlakase a fanoeng e lahleha e le mocheso. Empa a re hlahlobeng ka hloko: Phetisetso ea mocheso e ka boela ea hlalosoa e le mocheso oa mocheso ho ea ka yuniti (ea) sebaka (boima ba mocheso oa mocheso). Joalokaha mehlala e setšoantšong e bontša, mocheso oa mocheso likarolong tse ngata tsa elektronike o ka ba o feteletseng. Bophahamo joalo ka 'metsong oa rokete moo mocheso o ka bang 2 800 °C o ka hlahang.

Coefficient ea katoloso ea mocheso ke ntlha e 'ngoe ea bohlokoa bakeng sa li-semiconductors tsohle. Haeba semiconductor le base plate material e ka hola le ho kontraka ka lebelo le fapaneng ha e tobane le diphetoho tsa mocheso, kgatello ya motjhini e hlaha. Tsena li ka senya semiconductor kapa tsa senya khokahano lipakeng tsa chip le sepharalatsi sa mocheso. Leha ho le joalo, ka lisebelisoa tsa rona, ua tseba hore u matsohong a sireletsehileng. Lisebelisoa tsa rona li na le coefficient e nepahetseng ea katoloso ea mocheso bakeng sa ho kopanya li-semiconductors le lirafshoa.

Joaloka lipoleiti tsa motheo tsa semiconductor, mohlala, lisebelisoa tsa rona li sebelisoa ho li-turbine tsa moea, literene le lisebelisoa tsa indasteri. Ka li-module tsa semiconductor tsa matla bakeng sa li-inverters (thyristors) le diode tsa matla, li bapala karolo ea bohlokoa. Hobaneng? Ka lebaka la coefficient ea bona e nepahetseng ea katoloso ea mocheso le tšebetso e ntle ea mocheso, lipoleiti tsa motheo tsa semiconductor li theha motheo o tiileng oa semiconductor ea silicon e nang le kutloelo-bohloko le ho netefatsa bophelo ba tšebeletso ea mojule oa lilemo tse fetang 30.

Lisebelisoa tsa mocheso le lipoleiti tsa motheo tse entsoeng ka molybdenum, tungsten, MoCu, WCu, Cu-Mo-Cu le Cu-MoCu-Cu laminates li senya mocheso o hlahisoang likarolong tsa motlakase ka botšepehi. Sena ka bobeli se thibela ho futhumala ha lisebelisoa tsa motlakase le ho eketsa bophelo ba sehlahisoa. Lisebelisoa tsa rona tsa mocheso li thusa ho boloka tikoloho e pholileng, mohlala, ka li-module tsa IGBT, liphutheloana tsa RF kapa li-chips tsa LED. Re thehile sesebelisoa se ikhethileng sa MoCu bakeng sa lipoleiti tse tsamaisang li-chips tsa LED. Sena se na le coefficient ea katoloso ea mocheso e tšoanang le ea safire le lirafshoa.

Re fana ka lihlahisoa tsa rona bakeng sa indasteri ea lisebelisoa tsa elektronike ka mefuta e fapaneng ea liphahlo. Li sireletsa thepa khahlanong le kutu le ho ntlafatsa khokahano ea solder pakeng tsa semiconductor le thepa ea rona.
