Al2O3 Alumina Ceramic Substrates
Substrates from 0.1mm thick, with in-house laser cutting, drilling, scribing and marking.
- ShapeCustom
- MaterialAlumina
- Density3.8 g/cm3
Electronics And Semiconductor
Insulating parts that carry heat away from a device without carrying current.
Industry Pain Points
- A polymer insulator softens long before the assembly reaches process temperature.
- Heat has to leave the component, but the same path must not conduct electricity.
- Substrate outlines, holes and break lines have to be cut without chipping the edge.
What Buyers Ask For
- Alumina substrates from 0.1mm thick with a dielectric strength above 10 KV/mm.
- Laser cut outlines, microvias down to 100um and scribed break lines.
- Vacuum chuck plates and insulator plates that stay flat after grinding.
