Heavy Copper Board products are used extensively in power electronic devices and power supply systems. With the growing trend of the PCB industry, the finished copper weight of this unique heavy copper PCB type exceeds 4oz (140μm). And the copper weight of a standard PCB copper thickness is typically 1oz (35μm) or 2oz (0μm).

The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Other advantages include increased mechanical strength at connector sites, the ability to create a smaller product size by incorporating multiple weights on the same layer of circuitry and the ability to use exotic materials to their maximum capacity with minimal risk of circuit failure.

Heavy Copper Board Advantages

1. Increased endurance to thermal strains.
2. Increased current carrying capacity.
3. Increased mechanical strength at connector sites and in PTH holes.

  • Take advantage of exotic materials to maximize potential (ie, high temperatures) without circuit failure.
  • Reduced product size by incorporating multiple copper weights on the same layer of circuitry.
  • Heavy copper plated vias carry higher current through the board and help to transfer heat to an external heatsink.
  • On-board heatsinks directly plated onto the board surface using up to 120-oz copper planes.
  • On-board high-power-density planar transformers.

1. Is it ok if I want some free samples?
Yes, we can supply you with free samples if you have mass production order.

2. What is the minimum order quantity if I want to order PCB?
We don't have MOQ. We accept any quantity even one piece.

3. If I want to get a quotation from Aluminum PCB, Metal Core PCB, LED PCB, what should I do?
You can kindly send us the Gerber file, specifications of your requirement, we will quote immediately for you.

4. If I have special requirements for PCB material, how to deal with it?
We can make many kinds of special material PCB, for more details, please contact our sales.

5. Could you offer a custom layer stack up?
Yes, we do, in order to guarantee your PCB work well, we can offer it to you.

6. Do you supply a plastic case for our product?
We supply customized plastic or metal housing/enclosure for your PCBA products.

7. Could you do BGA assembly and X-RAY testing?
All of BGA pitch distance smaller than 0.4mm will have to go through X-RAY testing.

8. What files should I provide if order PCB or PCBA?
To make a PCB, please provide Gerber file, If you need PCBs to be assembled, you should also provide us a BOM list and Pick & place file.

9. How many days for making PCB? How long does it take for a PCBA order?
Usually 2-4 working days for PCB samples, 10-15 working days for bulk order. PCBA depends on the project, from PCB making to components purchasing till assembly work, it usually costs 2-4 weeks.

10. What payment terms are available? Can I pay via PayPal, T/T, Western Union?
We accept Paypal, T/T, Western Union. If you have any other questions about payment, please contact us to sales@miraclepwb.com.
