Introduction to Alumina High Polished
Sheets
• An alumina high polished sheet is a precision
ceramic product made from high purity aluminum
oxide (Al₂O₃).
• These sheets are available in various grades such
as 99.8% alumina polished sheet, offering near-
perfect purity for sensitive electronics.
• High polished alumina sheets feature ultra-flat,
mirror-like surfaces, essential in electronics and
microfabrication.
• Available in forms like alumina wafer polished
sheets and fine polished alumina substrates, these
materials are tailored to advanced manufacturing.

Why the Electronics
Industry Relies on
Alumina
• Electrical Insulation:
Using a high polished alumina sheet
minimizes electrical leakage in PCBs and
semiconductor modules.
• Superior Heat Management:
A fine polished alumina substrate quickly
dissipates heat from chips, improving device
lifespan.
• Mirror-Flat Surface:
An alumina mirror finish sheet ensures
accurate thin film deposition &
photolithography.
• Chemical & Thermal Stability:
Ideal under harsh flux, solder & cleaning
cycles.
Core Applications in Electronics
• Semiconductor Wafer Handling:
Alumina wafer polished sheets support fragile silicon wafers during
processing.
• LEDs & Laser Mounts:
High purity alumina polished sheets manage heat & isolate circuits.
• Hybrid Circuits & RF Modules:
Custom polished alumina sheets serve as substrates that handle both high
frequency signals & thermal loads.
• MEMS & Sensors:
Ultra-flat fine polished alumina substrates act as microstructure carriers.
