Product Description

Laser Scribing AlN Ceramic Base PCB Heatsink Aluminium Nitride Substrate

Product Introduction

About Laser Scribing

Due to the special properties of ceramic substrate materials, they generally cannot be processed by traditional processing techniques, and laser is an ideal tool for processing such materials.


Laser scribing has high precision, fast speed, no scratch on the workpiece and no mechanical deformation, and can process any graphics.
