| High Light | High Dielectric Alumina Substrate ，High Voltage Ceramic Spacer ，Power Electronics Al2O3 Plate | ||
Power electronics components must isolate high voltages while conducting heat away from switching devices, a combination that excludes most insulating materials. Our High-Dielectric-Strength Al2O3 Ceramic Substrate Plates solve both sides of the problem: they withstand repeated high voltage stress thanks to dielectric strength of 16 kV per millimeter, while their ceramic structure conducts heat more than twenty times better than typical PCB materials.
The plates are manufactured with tightly controlled thickness and camber so that power modules, IGBT substrates and heater plates assemble with uniform thermal contact. Surface finish can be specified as fired, ground or polished, and metallization can be added for direct bonding applications where the customer requires a ready to etch DBC style blank.

These plates serve power electronics components including IGBT module insulation, power resistor bases, heater plate insulation, high voltage power supply spacers, solid state relay insulation and thermoelectric module substrates.
For module manufacturers we provide matched substrate lots with verified thickness, camber and dielectric testing data, supporting high yield assembly processes.
Packaging & Quality AssuranceSubstrates are interleaved with clean tissue paper, packed flat in rigid boxes with foam protection and shipped with edge protection against chipping.
Each lot is inspected for thickness, camber, surface quality and dielectric integrity before release, with reports supplied on request.
