FAQs


Q1. What information should we supply to get a quote?

Please offer the specification of ceramic substrates, such as shape, dimension, quantity, application etc.


Q2. What types of alumina substrates are available?

Alumina substrates are available in a variety of types, including uncoated, coated, and laser-etched. The type of substrate used will depend on the application and the desired properties.


Q3: What is the difference between alumina substrates and other ceramic substrates?

Alumina substrates have higher electrical insulation than other ceramic substrates, such as beryllium oxide or aluminum nitride. They also have higher thermal conductivity and better mechanical stability than other substrates.


Q4. What is the lead time for the alumina substrates?

The lead time for the alumina substrates is dependent on the size and quantity required. Please contact us for more information.



How to clean alumina substrate

1. First, wipe the substrate with a damp cloth to remove dust and dirt.

2. Use a soft bristle brush and a mild detergent solution to scrub the substrate.

3. Wash the substrate with clean water, and then dry it with a soft cloth.

4. Ensure that the substrate is dry when used next time.



Quality testing standards

1. Visual inspection of the substrate for any signs of damage or irregularities.

2. Measurement of the length, width, and thickness of the substrate to check for accuracy.

3. Checking for any pinhole defects in the substrate.

4. Verification of the material and chemical composition of the substrate.
