The official AMB page describes substrates made from silicon-nitride ceramic and thick copper for high-power modules.
This describes product uses and material structures. It does not establish the initial thermal-resistance bottleneck or improvement for this sample. Confirm actual thicknesses, bonds, thermal boundaries and engineering batch quantities.
