The scribing spot can be in different sizes. Generally there are small spot 0.03-0.04mm (Substrate Thickness≤0.5mm ) and large spot 0.08-1.0mm (Substrate Thickness>0.5mm), and the accuracy is ±0.01mm. |
Laser Scribing ceramic substrates has been increasingly popular since its introduction to the industry nearly 50 years ago. The process involves pulsing a CO2 laser through an optical configuration, through a focusing lens, focusing the beam through an air assisted nozzle assembly, and finally onto the substrate's work surface. Most Laser scribing systems utilize a CNC or PC based motion control system, moving the substrate below the fixed beam assembly at speeds as fast as 10 in./sec, or faster.
Remark:
We not only produce alumina ceramic substrates, but also making both silicon ntiride(Si3N4) ceramic substrate and aluminum nitride (AlN) ceramic substrates.
Q01: What sizes are available for the Alumina substrates?
A: The typical largest size available is 280x240mm. Maximum standard thickness is 1.27mm and up to 2.0mm thicknesses are available per request. We offer customized products for special requirements.
Q02.What are the main advantages of a Ceramic PCB?
