Jinghui Ceramic is dedicated to producing high quality ceramic substrates. Our bare ceramic substrates are available in a wide range of standard and custom thickness, shape, and size. For products that require high dimensional accuracy, we can use various machining methods to process ceramic substrates, such as lapping, polishing, laser scribing, laser cutting, etc.

 

Precision Machining Machine

 

 

Ceramic substrate is a special type of PCB substrate. Because its heat dissipation performance, current carrying capacity, insulation, thermal expansion coefficient, etc. are much better than ordinary glass fiber PCB boards, it is widely used in high-power power electronic modules, aviation and aerospace, military electronics and other products. But the disadvantage that we cannot ignore is that the ceramic substrate is brittle.

Traditional machining methods will generate stress during processing, and for thinner ceramic substrates, it is easy to break. With the development trend of light weight and miniaturization, traditional cutting methods can no longer meets people’s expectations. As a non-contact processing tool, laser has greater advantages over traditional processing techniques and plays an important role in ceramic substrate processing.

Frequently Asked Questions

Q1: What is the minimum thickness of your alumina ceramic substrates?

Our standard thickness includes 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. Welcome to inquire about customized services.

 

Q2: How are ceramic substrates packaged to avoid breakage?

Because ceramics are brittle materials, each of our products will be packed in a safe and reliable way to avoid damage during transportation.

 

Q3: Can alumina ceramic substrates be polished?

Yes, lapping and polishing will provide the desired flatness and thickness tolerance, with a surface roughness generally below Ra0.05.

 

Q4: What is the camber of your alumina ceramic substrates?

Our alumina substrates are 100% inspected for camber. Our camber is controlled within the following range.

Alumina Ceramic Substrate
S/N Type Camber
1 96% alumina ceramic substrate, thickness < 0.3 mm 5‰
2 96% alumina ceramic substrate, other thicknesses 3‰
3 Alumina ceramic substrates in other purities 3‰
