Iinkqubo ze-Infotainment nazo zisebenzisa ezi bhodi. Itekhnoloji entsha yePCB ivumela abaqulunqi babeke iinxalenye ezininzi kwiindawo ezincinci. Oku kwenza ukuba izithuthi zombane zisebenze ngcono.
Kwixesha elizayo, iiPCB ziya kuba ncinci kwaye zibhetyebhetye ngakumbi. Kananjalo baya kusebenzisa imathiriyeli ezilungele okusingqongileyo.
Ukwazi ukuba zisebenza njani ii-PCBs kunceda iinjineli zakhe iimoto ezingcono. Ikwabanceda bahlale beneembono ezintsha.
Funda malunga notshintsho olutsha lwe-PCB ukubona ukuba lutshintsha njani uthutho kwixesha elizayo.
FAQ
I-PCB yenza ntoni kwisithuthi sombane?
I-PCB idibanisa iindawo zombane emotweni. Inceda ibhetri, imoto, kunye neenkqubo zokhuseleko zisebenze kunye. Iinjineli zisebenzisa iiPCBs ukugcina imoto ikhuselekile kwaye isebenza kakuhle.
Kutheni izithuthi zombane zifuna iiPCB ezikhethekileyo?
Izithuthi zombane zisebenzisa amandla amaninzi kwaye ziba shushu. Zikwangcangcazela kwaye zinokumanzi. IiPCB ezikhethekileyo zenziwa ukusingatha ezi meko zinzima. Basebenzisa izinto ezinzima kunye noyilo oluhlakaniphile ukugcina imoto ikhuselekile kwaye isebenza.
IiPCB zinceda njani ngokhuseleko lwebhetri?
IiPCBs kwinkqubo yolawulo lwebhetri jonga iseli nganye yebhetri. Bajonga amandla ombane kunye nobushushu kumntu ngamnye. Ukuba kukho into engalunganga, iPCB inokumisa ibhetri ukuba ingenzakali.
Zeziphi izinto ezisetyenziswa ziinjineli kwii-EV PCBs?
imathiriyeli | INzuzo engundoqo |
|---|---|
I-FR-4 | Yomelele kwaye iyafikeleleka |
IPolyimide | I-Flexible kwaye iyamelana nobushushu |
ialuminiyam | Ilungele ukupholisa |
Ezi zixhobo zinceda ii-PCBs zihlale ixesha elide kwaye zisebenze ngcono kwiimoto zombane.
Ngaba ii-PCB zingenza izithuthi zombane zibe namandla ngakumbi?
Ewe! IiPCBs zinceda ukulawula indlela amandla ahamba ngayo emotweni. Baqinisekisa ukuba amandla aya apho afuneka khona. Oku kunceda ukuba ibhetri ihlale ixesha elide kwaye imoto isebenzise amandla amancinci.
