Laser Cutting Scribing Aluminum Nitride Substrate Aln Ceramic Heatsink

Product Description

Laser Cutting Scribing Aluminum Nitride Substrate AlN Ceramic Heatsink

Product Introduction

About Laser Cutting

Ceramic substrate is the basic material of high-power electronic circuit structure technology and interconnection technology, and its structure is dense and brittle.

Conventional processing methods will generate stress during processing, and for thinner ceramic substrates, they are prone to fracture.

With the development trend of light weight and miniaturization, traditional cutting methods can no longer meet people's requirements for products.

As a non-contact processing tool, laser has greater advantages compared with traditional processing technology, and plays an important role in ceramic substrate processing.
