Silicon Nitride (Si3N4) printed circuit board (PCBs) coated with gold (full cover)

High-density silicon nitride gold-clad laminates are highly suitable for high-power and high-voltage circuit board requirements. The unique gold-clad process enables the perfect bonding of copper foil to silicon nitride substrate, effectively preventing delamination and significantly improving the yield rate of customer-side processes.

Nitride ceramic substrate has high hardness and strength, good thermal conductivity, low coefficient of thermal expansion, low high-temperature creep, resistance to oxidation and corrosion, low friction coefficient, and is a ceramic material with excellent comprehensive performance.
