Built for Extreme-Density AI Hardware

From CPO switches to laser arrays, our Cu-metallized substrates enable next-generation power delivery and thermal management.

CPO Switch Baseplates

51.2T/102.4T network switch ASICs

Cu-plated SCD baseplates provide identical CTE and sub-0.1K temperature uniformity across the entire switch, maintaining absolute optical alignment while providing electrical routing for drivers.

High-Density Power Delivery Networks

48V to 1V multi-chip power conversion

Cu-metallization allows direct AuSn soldering of multiple power diodes and MOSFETs onto a single diamond plane. Shrinks footprint by allowing tight component packing without thermal cross-talk.

ELSFP Laser Submounts

CW laser arrays for CPO external light sources

Copper traces enable multi-channel electrical driving of dense EML/DML laser arrays while the SCD base instantly removes junction heat, extending laser lifespan and increasing optical output power limits.
