Polished Yttrium Stabilized Zirconia PCB Substrate Zro2 Ceramic Insulation Board
Jinghui Ceramic can customize production and processing according to customer requirements and size specifications, with an accuracy of up to ±0.005mm.
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.
