How to choose the right one? – 2 PCB & MCPCB series – Best Technology

On our last blog, we introduce the definition and basis of the Corporation of Copper PCB. But the copper core PCB is not the only metal core PCB, aluminum PCB provides good heat dissipation as well. So, when working with a metal core board, many engineers and buyers are not sure whether to choose an aluminum PCB or copper core PCB. Some believe copper is always better, while others use aluminum at a lower cost. Today, we will guide you how to choose it, then let’s get started!

Material comparison: Copper vs Aluminum Core

Both copper and aluminum are used as core material for thermal management on PCB, but the physical and electric properties are significantly different:

Copper provides superior conductivity and better stiffness but comes at a much higher cost and weight. Aluminum is lighter, easier for machines, and cost effective for middle class applications.

Thermal Management: Which one handles better heat?

When heat dissipation is your top priority, copper clearly wins. High thermal conductivity allows heat to spread faster and more evenly, which is very important in high power applications such as:

• LED spotlights and stadium lighting
• Automotive headlights
• Power Converters and Inverters
• Laser driver module

Sample case: A customer replaces the aluminum PCB with a copper base for 100W LED drivers. The operating temperature drops 15 ° C, drastically increases the life of the product.

However, in a low power system to mid-”such as ceiling lamps, LED lights, or aluminum camera lights rings are usually sufficient. Using copper in this case is often unnecessary and increases costs without clear benefits.

Mechanical strength and weight: What does your design need?

Copper core PCB is heavier and more rigid, which makes it better for industrial applications exposed to vibration cycles or extreme temperatures.

But in products where weight is important “such as drones or devices that can be worn” PCB aluminum is a smarter option. They are easier for machines, routes, and gathering. The price is also cheaper in terms of tools and manufacturing time.

Choose Copper core PCB If you need:

• High mechanical stability
• Vibration resistance
• Long -term thermal durability

Choose Aluminum PCB If your product needs:

• Light design
• Control costs
• Simpler stomach and drilling

Cost Consideration: Is copper always commensurate?

Honestly: Copper core PCB can be worth up to 3x more than aluminum PCB. So you have to ask yourself ‘€ “Is a higher thermal performance really needed for your design?

Aluminum PCB is a better choice when:

• Your application does not exceed 80Wâ € “100W
• Weight and cost is a design priority
• You are in mass production and require price stability

Copper core PCB justified when:

• Your system needs to handle heavy heat loads
• High -current density involved
• Long -term reliability is more important than price

Many of our customers reduce the total cost of the project by switching to the aluminum PCB without sacrificing performance so that we review their thermal simulation data.

5 main points before you choose

Still not sure which basic ingredients are suitable for your needs? Walk through this five -step checklist:

If you answer “height” for performance at most points, copper is likely to go. If not, aluminum is your best cost performance option. Talking, if you are not sure after answering, consult with your PCB manufacturer. At most technology, we provide application-based advice to help you choose between aluminum PCBs and copper core PCBs-without excessive expenditure.

FAQ

T1: Can I use an aluminum basic PCB for high power applications?

Only for medium heat loads. For power systems> 100W, copper is highly recommended.

T2: What is the thinnest aluminum or copper base that you can give?

We can produce a 0.8mm basic thickness for both, depending on the structure.

T3: Do you offer a hybrid metal core PCB?

Yes, we can integrate aluminum and FR4 or support copper-ceramic hybrid design.

T4: How long is the waiting time for a copper vs aluminum base?

Aluminum PCB: 5â € “7 working days; Copper PCB: 7â €” 12 days depending on complexity.

T5: Can I get the thermal simulation before ordering?

Very! We offer pre-production thermal analysis and structural design assistance.

T6: Is PCB Copper Core compatible with the standard SMT process?

Yes, they. We offer full SMT assembly services for aluminum and copper base boards.

T7: How do I know which type is the best for my application?

Send your design or specifications to us, and we will recommend the most efficient and reliable options.

Conclusion

Choosing between copper core PCB and aluminum PCB is not about choosing better material. It’s about choosing what is right for your application. Copper is very strong but expensive; Aluminum is flexible and affordable.

When designed and selected correctly, aluminum PCBs can outperform expectations, and copper core PCB can save your system from thermal failure. Match the material with the environment, budget, and your performance objectives € “and you will never be wrong. On our next blog, we will share how to choose copper thickness.
