Manufacturing Capacity

1. Our bare ceramic substrates are available in a wide variety of standard and custom thickness, shape, and size. 

(1) The standard thickness of the alumina ceramic substrate is 0.25mm, 0.30mm, 0.38mm, 0.50mm, 0.635mm, 0.76mm, 0.80mm, 0.89mm, 1.0mm, 1.5mm and 2.0mm. Minimum thickness to be 0.1mm. 

(2) Our rectangular shapes for as-fired alumina ceramic substrates are available up to 500mm×500mm.

2. For products that require high dimensional accuracy, we can use various processing methods to process ceramic substrates, such as lapping, polishing, laser scribing, laser cutting, etc.

φ≤0.5	0.08
φ>0.5	0.2

(2) Laser Scribing
 

Alumina Ceramic Substrate
Substrate Thickness (mm)	the Percentage of Laser Scribe Line Depth to Thickness (%)
0.2-0.3	40%±5%
0.3<T≤0.5	50%±3%
0.5<T≤1.0	43%±3%
