Product Overview

3D dam aluminum nitride (AlN) LED substrates are advanced ceramic circuit carriers designed with integrated three-dimensional barrier (dam) structures. These dams effectively control adhesive or phosphor flow during LED packaging, preventing overflow and ensuring uniform distribution.

Combined with the high thermal conductivity of AlN, 3D dam substrates significantly improve thermal management, optical consistency, and packaging reliability—making them ideal for high-power LED and COB applications.

Key Features

1. Integrated 3D Dam Structure
