Product Description

Precision Machining Alumina Plate Surface Mirror Polishing Black Ceramic Substrate
 

Product Introduction

Currently, the color of alumina used in semiconductor and display manufacturing equipment is mainly white or ivory, which reflects light and causes glare when used as components around light sources or in the focal plane.

Black alumina ceramics have unique light-shielding properties that can suppress surface light reflection while maintaining the strength and durability of fine ceramics. Therefore, black alumina ceramic substrates are used when they need to be applied in a light-shielding environment.

In some integrated circuit sealing links, plastic packaging materials can also be processed into black, but black plastic packaging materials are inferior to ceramic packaging materials in terms of moisture resistance, airtightness, chemical stability and thermal shock resistance, and are difficult to meet the requirements of certain special packaging.
 

 

 

Product Applications

Black alumina ceramic substrates have excellent comprehensive properties such as high mechanical strength, good insulation and light-shielding properties, and are widely used in multi-layer wiring ceramic substrates, electronic packaging and high-density packaging substrates.
