Litharollo tsa Tlhahiso ea PCB ea ho tjhaja ka potlako

Highleap Electronics ke k'hamphani e felletseng ea ho etsa le ho kopanya PCB e sebeletsang liindasteri tsa makoloi, likhokahano tsa mehala, matla le lisebelisoa tsa elektroniki tsa bareki. Har'a bokhoni ba rona bo fapaneng, li-PCB tse tjhajang ka lebelo le phahameng haholo li emela pheletso ea theknoloji ea phepelo ea motlakase — e nolofalletsang ntho e 'ngoe le e 'ngoe ho tloha ho li-charger tsa 100W ho isa ho li-supercharger tse 350kW EV tse hlalosang litebello tsa lebelo la ho tjhaja.

Litharollo tsa Koporo e Boima bakeng sa Tšebeliso e Feteletseng ea Hona Joale

Ho tjhaja ka potlako ho hloka maemo a hajoale a ka senyang li-PCB tse tloaelehileng hanghang. Chaja ea 350kW e tsoela pele ho sutumetsa li-amps tse 500+—hona joale e hlokang mekhoa e fetohileng ea moralo oa PCB ho sebetsa ka mokhoa o sireletsehileng le ka katleho.

Re kenya koporo e boima ho tloha ho 6oz ho isa ho 20oz botenya, ho feta 1-2oz e sebelisoang ho lisebelisoa tsa elektroniki tse tloaelehileng. Empa ho etsa koporo e boima ho hlahisa mathata a ikhethang. Etching e tloaelehileng e lahleheloa ke ho nepahala ka koporo e teteaneng, ho theha undercut e fokolisang mesaletsa. Tšilo ea rona e tebileng e laoloang e boloka mamello ea botenya ba ± 10% esita le ho boima ba 20oz.

Lintlha tsa bohlokoa tsa moralo bakeng sa boemo bo holimo:

• Litsela tse ngata tse bapileng li tsamaisa mojaro oa hajoale
• Ka li-arrays tse nang le 50+ thermal vias tlas'a likhokahano
• Boima ba hajoale bo bolokiloe ka tlase ho 30A/mm²
• Ho leka-lekanya koporo ho thibela ntoa ea boto

Phapang pakeng tsa katleho le ho hloleha hangata e itšetlehile ka kabo e nepahetseng ea hona joale. Phihlelo ea rona ea PCB ea ho tjhaja motlakase oa EV e sebetsa ka kotloloho litlhokong tsena tse feteletseng tsa hona joale, e leng se netefatsang ts'ebetso e tšepahalang ka mashome a lilemo.

Tsamaiso ea Thermal ho Kilowatt Scale

Ho 350kW, esita le 98% e sebetsang hantle e bolela 7kW ea litšila tsa mocheso-e lekanang le liomisa moriri tse supileng sebakeng se senyenyane ho feta laptop. Ntle le moralo o ikhethang oa mocheso, likaroloana li ne li tla hloleha ka mor'a metsotsoana.

Re kenya tšebetsong meralo e felletseng ea mocheso ho kenyelletsa le libarele tse phuthetsoeng ka koporo bakeng sa 3x conductivity e betere, e tlatsitsoeng ka li-vias tse tlosang likheo tsa moea, le li-metal-core substrates ha FR-4 e fihla meeling ea eona. Aluminium substrates fana 5W/mK thermal conductivity, ha koporo substrates fana 380W/mK—ho feta 1000x betere ho feta standard FR-4.

Bakeng sa lits'ebetso tse thata ka ho fetisisa, ho pholisa metsi ho ba tlamo. Re rala li-PCB tse nang le tokisetso e kopaneng ea ho pholisa—libaka tsa ho kenya bakeng sa lipoleiti tse batang, ntlafatso ea thepa ea sebopeho sa mocheso, le lipotoloho tse arohaneng tsa ho lekola mocheso. Meralo e meng e tsoetseng pele e kenyelletsa liteishene tsa ho pholisa ka kotloloho sebopehong sa PCB, leha sena se hloka bokhoni bo khethehileng ba tlhahiso boo re bo ntlafalitseng ka merero ea rona ea PCB e nang le matla a mangata.

Li-Semiconductors tsa Wide-Bandgap li nolofalletsa Phetohelo

Silicon carbide (SiC) le gallium nitride (GaN) semiconductors li fetotse ho tjhaja ka potlako ho tloha ho bohelehele ba laboratori ho ea ho 'nete ea khoebo. Lisebelisoa tsena li fetola 10x ka potlako ho feta silicon e nang le tahlehelo e tlase haholo, e nolofalletsang katleho le matla a matla a hlokahalang bakeng sa ho tjhaja ka potlako haholo.

Empa lisebelisoa tsa li-bandgap tse pharaletseng li hloka moralo o ikhethang oa PCB. Ka lebelo la ho fetoha la 50V/ns, millimeter e 'ngoe le e 'ngoe ea trace e bohlokoa. Inductance ea likokoana-hloko e sa kang ea ama silicon IGBTs joale e baka tšenyo e feteletseng ea motlakase ka SiC le GaN.

Ntlafatso ea sebopeho bakeng sa lisebelisoa tse pharalletseng tsa bandgap:

• Li-loops tsa matla tse otlolohileng li sebelisa likarolo tse haufi
• Ka li-arrays bakeng sa liphetoho tse fokolang tsa inductance
