In order to provide a high-reflectivity composite material of this kind which exhibits improved electrical connectivity when surface-mounting procedures are used, it is proposed that the thickness of the interlayer is in the range 5 nm to 200 nm, and that a layer of a metal or a metal alloy has been applied superficially on side (B) of the carrier that is opposite to the optically active reflection-boosting multilayer system, where the electrical resistivity at 25° C. of the metal or metal alloy is at most 1.2×10−1 Ωmm2/m, where the thickness of the layer applied superficially is in the range 10 nm to 5.0 μm."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reflective composite material, in particular for surface-mounted devices (SMD), and light-emitting device with a composite material of this type","description":"A reflective composite material with a carrier consisting of aluminum with, on one side (A) of the carrier, an interlayer made of aluminum oxide, and with, above the interlayer, an optically active re","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11469357","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
