The chip carrier includes a ceramic substrate, a circuit layer, a ceramic reflective plate disposed on the ceramic substrate, and a metal slug. The ceramic substrate has a first thru-hole. A main portion of the metal slug is embedded in the first thru-hole, and partially protrudes from the first thru-hole with a height of 10˜30 μm to define as a protrusion block. An extending portion of the metal slug is connected to the outer edge of protrusion block, and the top surfaces of extending portion and protrusion block are coplanar to define a mounting surface. The ceramic reflective plate has a second thru-hole, and the mounting surface is exposed from the ceramic reflective plate via the second thru-hole. The LED chip is fixed on the mounting surface and is electrically connected to the circuit layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"LED package structure and chip carrier","description":"An LED package structure includes a chip carrier and an LED chip.
