Product Description

Excellent Flatness Alumina Ceramic Sheets Al2O3 Thin-film Substrates
 
Product Introduction

We are a supplier of customized alumina ceramic substrates. Our products are environmentally friendly, highly stable, corrosion-resistant, high-temperature resistant and with accurate dimensions. If you need alumina ceramic substrates, please choose Jinghui Ceramic for fast production and delivery!

Alumina ceramic is the most common substrate material you'll find in today's printed circuit boards. It boasts an excellent balance of thermal and electrical conductivity when compared to other oxide ceramic substrates.

The alumina ceramic substrate is also reputed for better mechanical strength and chemical stability and is readily available. These properties make it the ideal option for technical manufacturing, especially when various shapes have to be considered. If used in circuit boards, the purity of alumina is usually 96% or 99.6%.
