Description

Aluminum Nitride (AlN) is the best performing ceramic substrate for electronic circuits because of its high thermal conductivity (170 W/mK), low coefficient of thermal expansion (CTE), rigidity and dielectric strength. These properties make it the perfect material for high power circuits for LED/laser application, power management, ultra-low temperature electronics, and many more applications.

If you are looking to test this material and only need a few parts at low cost and lead time. Check out our Aluminum Nitride C-Proto solution.

FAQ - Ceramic PCB (C-Production)

When should I consider ordering via C-proto and when via C-production?

Answer: C-proto is perfect for people that only need a few pieces (5 panels or less => Please note; depending on the size, several PCB may fit on one panel). And the design needs to be relatively simple with only limited options regarding thickness, finish, and masking. The advantage of C-proto is that you can have your PCB relatively fast and at a much lower cost as you do not need to pay for tooling. C-proto orders are made on a specifically designed production line for prototypes and low volume.

C-production orders, on the other hand, will be made on a fully-fledged ceramic PCB production line at one of our partners which are designed for higher volume orders. It gives you many more options and tighter specifications but the downsides are price and longer lead time.

Where are the C-Production orders made?

Answer: We have several production partners in China, Taiwan, India, the USA, and Europe. In order to ensure consistent quality, every order standard passes our Belgian location for a final quality check before it is shipped to you.

Are there any import duties/tariffs that I need to pay?

You are responsible for local import formalities and duties on your order. Note that when you are based in the USA and choose copper metallization, your order will likely be made by our partner in China and is thus likely subject to a 25% tariff.

If you would like to avoid this, please switch to silver metallization (never made in China) or order via C-Proto if possible (made in Belgium). If both options do not suit you, contact us. We have other production partners in Taiwan that are also able to supply copper-based ceramic PCB but we need to quote this separately.

Can you ship faster?

Answer: We might. It depends on the production schedule of our partners. Contact us to discuss this.

How are Ceramic PCBs made?

Answer: we made a page about this that explains the different manufacturing technologies. Find it here.

Are ceramic pcb heavier or lighter then other PCB?

The substrate materials in itself, both Alumina 96% as well as Aluminum nitride are heavier then traditional pcb material like FR4 or even aluminum 5052 (metal core pcb). However, usually ceramic pcb are thinner (=< 1mm compared to 1.6mm typical) and require less copper (much heavier). In most cases the weight is therefor comparable or even lower. Below is an overview of the density of the different materials.

Al2O3 96%: >3.7 g/cm3 (typical thickness 0.25 - 1mm)
AlN: >3.33 g/cm3 (typical thickness 0.25 - 1mm)
FR4: 1.850 g/cm3 (typical thickness 0.8 - 1.6mm)
Aluminium (5052): 2.68 g/cm3 (typical thickness 1.5mm)
Koper: 8.96 g/cm3
