Why Choose the Aluminum Nitride Ceramic Substrate?
The aluminum nitride ceramic substrate has excellent thermal conductivity, reliable electrical insulation, low dielectric constant and dielectric loss, and is ideal for heat dissipation and packaging of LED lighting, large-scale integrated circuits, semiconductor module circuits and high-power devices.
Through the table below, you can see some performance comparisons between aluminum nitride (AlN) ceramic substrates and alumina (Al2O3) ceramic substrates.

Q1: What is the Maximum Service Temperature of the Aluminum Nitride Ceramic Substrates?
Aluminum nitride ceramic substrates can withstand high temperatures over 1000 ºC.
Q2: Do the Bare Ceramic Substrates Meet the Requirements for Metallized Ceramic Circuit Boards?
Yes. Metalized ceramic substrates, also known as metalized ceramic circuit boards, include bare ceramic substrates and metal circuit layers. Bare ceramic substrates are widely used in integrated circuit packaging, LED lighting, heat dissipation substrates, and other fields in the electronic industry due to their advantages of thinness, high-temperature resistance, high electrical insulation performance, low dielectric loss, and good chemical stability.
Q3: Can We Get Free Samples?
Samples of standard sizes are free, and we only charge for shipping. If customization is required, we only collect a sample fee for MOQ.
Q4: How Long is the Production Lead Time?
If the product is in stock, we will ship it within 1-2 days. The standard lead time for other orders is 4-6 weeks.
Q5: What is the Depth of the Laser Scribing?
The depth of the laser scribing of our ceramic substrate is about 35%-63% of the substrate thickness. The scribing spot can be in different sizes. Generally, there are small spots 0.03-0.04mm (Substrate Thickness≤0.5mm ) and large spots 0.08-0.1mm (Substrate Thickness>0.5mm), and the accuracy is ±0.01mm.
