Product Description

500mm * 500mm Large Size Al2O3 PCB Sheet Alumina Ceramic Substrate
Product Introduction

About the Size

The size of the alumina ceramic substrate is not the bigger the better, mainly because the base material is made of ceramics, and it is easy to cause the substrate to break during the PCB proofing process, resulting in a lot of waste.

Our rectangular shapes for as-fired alumina ceramic substrates are available up to 500mm×500mm.
