Innovacera's high-purity alumina (Al2O3, 96%-99%) substrates are the backbone of automotive electronic modules, including ECU, sensors, and LED lighting. With excellent electrical insulation, mechanical strength, and thermal conductivity, these substrates withstand harsh under-hood environments. Available in as-fired, lapped, or polished finishes, they support thick-film and thin-film circuits. Innovacera provides substrates with laser-drilled vias and metallization options for reliable solder attachment.
