Al2O3 Alumina Ceramic Parts
Al2O3 Alumina Ceramic Substrates and Thin Plates
Heat spreading insulating plates from 0.1 mm thickness with laser scribing
A substrate has to pull heat away from a device while keeping it electrically isolated, and it has to arrive flat and dimensionally correct or the assembly line stops. These alumina substrates run from 0.1 mm to 2.0 mm thick at a density of 3.8 g/cm3, hold a tolerance of plus or minus 0.02 mm, and can be laser scribed to 0.1 to 0.5 mm pulse depth for snap separation. Standard sizes ship in 1 to 2 days from stock.
Key Benefits
- Standard sizes in stock ship in 1 to 2 days, custom sizes in 5 to 7 days
- Tolerance of plus or minus 0.02 mm holds pick and place alignment
- Minimum thickness 0.1 mm for applications where thermal path length matters
- Laser scribing to 0.1 to 0.5 mm depth so panels snap cleanly into singles
- Minimum order quantity of 10 pieces, so prototypes do not need a production commitment
Problems It Solves
- Devices running hot because the isolating layer also blocks the heat path
- Substrate batches arriving out of flatness and jamming automated assembly
- Long lead times on small quantity substrate prototypes
Who It Is For
- Electronics manufacturers prototyping in small quantity
- Power module builders needing tight thickness control
- Designers comparing alumina, zirconia, aluminium nitride and silicon nitride bodies
Application Scenarios
Heat spreading plates under power electronics
Insulating layers in sensor and module assemblies
Laser scribed panels separated into individual carriers
Thermally stable carriers for high temperature electronics

Comparison With Other Ceramics
Alumina is the default substrate: good insulation, good strength, low cost. Aluminium nitride moves heat far better and is used when the thermal budget is tight. Silicon nitride is the tough option for substrates that see thermal cycling and mechanical load.
Use Guide
- Quote the thickness tolerance you actually need; tighter than plus or minus 0.02 mm needs discussion first
- Specify the scribe line pattern and the snap direction with the panel drawing
- Handle thin substrates at 0.1 mm with vacuum tooling rather than tweezers
