Kodi mitundu ya PCB zotayidwa magawo a opanga pcb
Pakalipano, gawo la aluminiyamu la LED lomwe limagwiritsidwa ntchito kwambiri lili ndi mbali ziwiri, mbali yoyera imagwiritsidwa ntchito powotcherera zikhomo za LED, ndipo mbali ina imasonyeza mtundu weniweni wa aluminiyumu.Magawo a thermally conductive amalumikizana.Nthawi zambiri, gulu limodzi limapangidwa ndi magawo atatu.Zoonadi, amene akuchidziwa ayenera kuchidziwa, ndipo kokha mwa kumvetsa zimenezi angasankhidwe bwino ndi kugwiritsidwa ntchito.Aluminiyamu gawo lapansi ndizitsulo zopangidwa ndi zitsulo zamkuwa zokhala ndi ntchito yabwino yochepetsera kutentha.Tiyeni tione mitundu ya PCB zotayidwa magawo a opanga pcb.
Flexible Aluminium Substrate
Chimodzi mwazotukuka zatsopano mu zida za IMS ndi ma dielectric osinthika, omwe amakhala ndi zotchingira bwino kwambiri zamagetsi, kusinthasintha komanso kusinthasintha kwamafuta.Akagwiritsidwa ntchito ku aluminiyumu yosinthika, mankhwalawa amatha kupangidwa m'mawonekedwe osiyanasiyana ndi ma angles, kuthetsa kufunikira kwa zingwe zamtengo wapatali zachitsulo ndi zolumikizira.Zodziwika bwino ndi ma subassemblies awiri kapena anayi opangidwa ndi ochiritsira FR-4, omangirizidwa ku gawo lapansi la aluminiyamu ndi dielectric yotentha kuti athetse kutentha, kuonjezera kuuma ndikuchita ngati chishango.Pamsika wochita bwino kwambiri zidazi zimakhala ndi gawo limodzi kapena zingapo zozungulira zokwiriridwa mu dielectric, zokhala ndi ma vias akhungu omwe amagwiritsidwa ntchito ngati njira zotenthetsera kapena njira zamawu.
Kupyolera mu dzenje aluminium gawo lapansi
M'mapangidwe ovuta, aluminiyumu amatha kupanga "core" ya multilayer thermal structure, yomwe imayikidwa kale ndikudzazidwa ndi dielectric isanayambe.Kupyolera mu mabowo amakutidwa ndi mipata ya aluminiyamu kuti asunge kudzipatula kwamagetsi, komwe kumatengedwa ngati ambulera ya PCB yoperekedwa kumakampani a LED chifukwa cha kutenthetsa kwake.
Zonse mwazonse, mitundu ya PCB zotayidwa gawo lapansi opanga pcb monga kusinthasintha magawo a aluminiyamu ndi kudzera-dzenje magawo zotayidwa.Pazogwiritsa ntchito, palinso mapangidwe a mbali ziwiri a gawo lozungulira, insulating layer, aluminiyamu base, insulating layer, ndi ma circuit layer structure.Ntchito zochepa zomwe zimakhala ndi matabwa amitundu yambiri, omwe amatha kupangidwa ndi matabwa wamba amitundu yambiri kuphatikiza zotchingira ndi magawo a aluminiyamu.Magawo a aluminiyamu ali ndi kutentha kwabwino kwambiri, makina abwino, kukhazikika kwazithunzi ndi magetsi, ndipo amagwiritsidwa ntchito kwambiri mumayendedwe osakanizidwa ophatikizika, magalimoto, makina opangira maofesi, zida zazikulu zamagetsi zamagetsi, zida zamagetsi ndi magawo ena.
