Introduction of Zirconia Ceramic Substrates

Zirconia ceramic substrates have good mechanical strength and chemical stability, and have good performance stability in high-temperature environments. They are often used for packaging and heat insulation of high-temperature electronic devices.

 

Why Polished

Three major benefits of lapping and polishing for the ceramic substrate:

- A finer pattern can be obtained.

- Better parallelism of the upper and lower surfaces (thickness tolerance) can be achieved.

- A thinner metallization layer can be acquired.
