Shaanxi Puwei, founded in 2017, continues to advance ceramic base material innovation with a focus on performance and reliability. Our high-precision laser-drilled aluminum nitride (AlN) ceramic substrates are engineered to meet the demanding thermal and mechanical requirements of high-power electronic applications.
AlN is one of the few materials that combines excellent electrical insulation with high thermal conductivity. This makes it an optimal solution for use in heat sinks, thermal spreaders, and insulating substrates in applications such as IGBT modules, HELED, power devices, TEC modules, and optical communications.
Our AlN ceramic substrates feature:
High thermal conductivity
Low dielectric constant and dissipation factor
Excellent electrical insulation
Superior mechanical strength
Low thermal expansion coefficient
Thanks to a strong in-house inventory, we offer rapid shipment and flexible customization. Substrates are available in various sizes and thicknesses, with support for precision laser drilling and machining for high-power laser systems.
