Product Description

Laser Cutting Any Graphics Bare AlN Aluminum Nitride Ceramic Substrate

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.

Manufacturing Capacity

Products of various specifications can be produced. The table below shows our standard thicknesses and sizes.

Laser Processing

(1) Hole Size
 

AlN Ceramic Substrate
Hole Diameter (mm)	Standard Tolerance (mm)
φ≤0.5	0.08
φ>0.5	0.2

(2) Laser Scribing
 

AlN Ceramic Substrate
Substrate Thickness (mm)	the Percentage of Laser Scribe Line Depth to Thickness (%)
0.2-0.3	40%±5%
0.5<T≤1.0	50%±3%
1.0<T≤1.2	55%±3%
1.2<T≤1.5	60%±3%
2.0	45% (Extreme Depth)
The scribing spot can be in different sizes. Generally there are small spot 0.03-0.04mm (Substrate Thickness≤0.5mm ) and large spot 0.08-0.1mm (Substrate Thickness>0.5mm), and the accuracy is ±0.01mm.
