Chip on board

Written By SDS

Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits are wired bonded directly to a printed circuit board, and covered by a blob of epoxy. COBs containing arrays of light-emitting diodes have made LED lighting more efficient.

Tip from a lighting designer

As lighting designers we separately check the COB and its origin, among other things we check the Colour Rendering Index (CRI), the colour temperature, etc.
