AlN Substrate By Feature
This board is “naked,” meaning it is made entirely of ceramic and has no components or routing. It can be utilized for projects.
You will benefit from rapid development for the prototype PCB when you use reliable, error-free AlN material in your job.
AlN is a type used in ceramic PCBs, so they are occasionally called ceramic. Though, there are other ceramics substrates.
AlN is a material that can be used in multilayer PCBs; particularly in the semiconductor industry, these are an affordable choice.
Customers use AlN material primarily for its high Tg, so it stands to reason that this is preferred for power applications.
Customers who require LED lighting must choose between Metal Core and AlN. Both are suitable for continuous, long-term use.
What is AlN Substrate?
It is a ceramic substrate material with the following features:
- High thermal conductivity
- Strong dielectric property
- Minimal and desired expansion factor
Because of AlN’s capabilities, it is ]frequently selected in in PCBs for:
High-power LED lighting, sensors, ICs and microcontrollers, RF devices, etc.
Oxidation is prevented even when exposed to 137 Celsius heat.
In addition, the material can be metallized using techniques similar to those used with alumina and beryllium oxide.
Why Use AlN Substrate on Circuit Boards?
Customers are drawn to AlN’s adaptability heat in particular. The strength of it against harsh elements is a plus. What they like:
- 0% water absorption, ideal for moist environs
- Efficiency compared to other substrates like FR4
- Low thermal expansion coefficient (3 to 4 ppm/C)
- Strong mechanical structure with a 450 MPa value.
- Thermal conductivity range (170 W/mK – 230 W/mK)
It makes sense if you consider the typical user of this substrate, such as the telecom industry.
Applications of AlN Substrate
It was previously mentioned that the major players in the telecom industry use the AlN substrate extensively.
However, there are some additional industries. If you choose a reliable manufacturer, the business is likely to be producing ODM or OEM PCB for businesses in the following industries:
A Reliable Supplier of AlN Substrate PCB
At PCBTok, we carefully and precisely manufacture PCBs using a unique manufacturing process.
The majority of consumer, industrial, and medical electronic products are built on flexible and rigid-flex types of polyimide.
We begin by choosing the best ecologically sound material for your project.
We at PCBTok are proud to produce PCBs of the highest caliber available. All of our products are expertly made and covered by a satisfaction guarantee.
AlN Substrate PCB Fabrication
Despite appearing expensive, this material is actually affordable due to its high level of efficiency. Consider the following:
- AlN material is mechanically robust in addition to being heat resistant. It has a wide range of applications.
- It makes for a superior copper conductor, particularly when DPC Ceramic processing is applied.
- Compared to Beryllium Oxide (BeO), it is a good substitute because it follows environmental safety restrictions.
- Additionally, it has a remarkable capacity for insulation, preventing accidental contact with other PCB surfaces.
AlN substrates are used in semiconductor industry because it can function even when exposed to daily usage and/or non-stop use.
Keep in mind that AlN is a type of ceramic PCB as well.
So, two of the Four Processes used to create ceramic PCBs are DBC Ceramic Processing and DPC Processing.
The LTCC (Low Temperature Co-firing) and HTCC (High Temperature Co-firing) are the other two additional processes. Reminder for packing: AlN materials are very photosensitve. For final covering, the item needs to be tightly protected from sunlight.
