The World Market for Chip on Board (COB) LEDs in General Lighting
Chip-on-board, or COB, packages contain a number of chips attached directly to the substrate, then packaged together by silica gel, epoxy resin, or other materials. COB assemblies improve package performance and are a preferred application by process engineers. This report looks at the COB packages that were specifically sold as COB, not simply manufactured in house and put into an end product.
