AI203 PCB: Pros, Cons & Typical Uses

AI203 PCB is a type of Ceramic Printed Circuit Board (PCB) manufactured to offer advanced thermal conductivity, facilitate wear resistance and improve the overall performance of the circuit board.

It is also known as the Alumina Printed Circuit Board. This article highlights the good and bad attributes of the circuit board. It also covers the typical uses or applications of the board.

Advantages of the AI203 PCB


Here are some of the benefits or advantages of using the AI203 PCB as one of the base materials for manufacturing a ceramic circuit board.

1. Multi-Range Availability

The AI203 PCB is readily available in different ranges of temperature. As a high-temperature conductivity PCB, it helps the digital designer to choose from the varieties of options.

The first range is the 96% AI203 PCB that comprises a thick-film substrate with special emphasis on manufacturing hybrid circuit devices.

The 99.5% AI203 PCB reduces the circuit’s board flexural strength and comes in several designs, including thicker and larger sizes.

The third variant of the AI203 PCB is the 99.6%. It is best for manufacturing circuit boards targeted at applications or devices requiring additional dielectric properties and excellent heat dissipation.

2. Heat Resistance

At the core of the AI203 PCB’s attribute is the reduction of (excessive) heat dissipation, especially by preventing the same from affecting the internal components of the board.

3. Good Thermal Conductivity

Balancing the heat needs and getting rid of the excess is also one of the attributes of the AI203 PCB. It adds this with the resistance of alkali and strong acid attacks at the highest-operating temperatures of the AI203 PCB.

4. Frequency Interoperability

The circuit board also switches between frequencies, especially by providing excellent dielectric properties from the DC to the GHz.

5. Strong Build

The AI203 PCB is able to withstand excessive thermal heat because of the strong construction. The board comes with a strong rigid material that withstands corrosion.

6. Zero Water Absorption

The chances of water or any form of liquid getting into the AI203 PCB is zero because of the excellent workings of the hermetic packages.

7. Enough Light Reflection

Inside the board is not dark, thanks to the white material/color that makes the interior visible.

8. Long-Lasting

The AI203 PCB is one of the circuit boards and development materials you can trust to last for a long time to come.

The long-lasting effect is derived both from the rigid and strong materials that ensure the board is working optimally at all times.

9. Compact Design

You don’t need to bother about how to place the AI203 PCB on your targeted applications. It has a compact design that features multiple layers that can further be configured for different uses within the broader device/application.

10. Affordable

Digital circuit consumers looking to save costs without comprising on quality often turn to the AI203 PCB because it offers just that.

11. Unmatched High-Frequency Performance

The AI203 PCB is designed for high-end and high-frequency applications. The higher operating temperature of 1500iC may prove to be an issue, but it isn’t.

Instead, it balances the superior temperature performance with the immediate need of preventing the temperature from going overboard.

Through the perfect balancing of these two operating scenarios, the AI203 PCB is able to boast of unmatched (greater) performance, even for high-frequency applications.

Downsides to Building Your Circuit Board Applications with the AI203 PCB

The good and the bad sides of the AI203 PCB coexist so you can balance these and decide if it is worth it.

Here are some of the potential downsides or probable reasons why you wouldn’t be willing to use the board:

1. The Costs can be Higher

We know that we said that the AI203 PCB is one of the affordable circuit boards you can find out there. However, the price range may be slightly expensive, if you are comparing it against either the metal core or FR4 Printed Circuit Boards (PCBs).

2. Fragility

Ceramics by default are fragile. Manufacturing a Printed Circuit Board (PCB) with ceramic as the base material could expedite the fragility, especially when other components are thrown into the board.

Typical Uses of the AI203 PCB

Here are some of the typical applications or use cases that can be derived from the AI203 PCB:

Automotive Products

Are you looking to manufacture electronics or similar products for the automotive industry? Using the AI203 PCB can guarantee a speedy execution of the job.

The higher operating temperature and the optimum balance between performance and heat dissipation helps put it above the other circuit board types.

Examples of automotive products that can be made out of the AI203 PCB are:

  • Shock absorbers
  • Vehicle/car engines
  • Car sensors

Medical Equipment

Medical and laboratory equipment is not left out of the applications. Examples of the devices that can be made out of the AI203 PCB in this niche are:

  • Sample holders
  • Laboratory instrument tubes

In addition to the above, the AI203 PCB can also be used when manufacturing the following:

  • Telecommunication devices/smartphones
  • Injection systems
  • Solar systems
  • Smart power modules, including Solid-State Relays (SSRs), and high-frequency switching power supplies.
  • Wire guides
  • Thermometry sensors
  • High-voltage insulators
  • Refrigeration sheets
  • Street lights
  • Light Emitting Diode (LED) products

How to Choose the Best AI203 PCB

The circuit board you want to choose should fit into the targeted applications. Consider reaching out to RayPCB for guidance on how to pick the best AI203 PCB that fits into your targeted devices.

The next thing you want to consider is the cost of buying the board. Although it is affordable, factors like the thermal conductivity requirements and the applications may impact the cost.

Also, have in mind that the cost of buying the AI203 PCB may be slightly higher than when buying either the FR4 or metal core circuit boards.

Quality of Service

What is the quality of the service rendered by your favorite AI203 PCB supplier? Does the supplier have a good star rating based on the buying or shopping experience of the former customers?


Working with the AI203 PCB has its good, bad and the ugly. You need to consider the application requirements and pick the right circuit board that does just to that need.
