Heraeus Printed Electronics

Why EMI Shielding?

Electromagnetic interference can disrupt electronic devices, equipment and systems. With the new generation of mobile phones especially for the new 5G technology, EMI shielding becomes more and more important. As frequencies increase, so does interference. Without proper shielding, our brand-new phones wouldn’t work.

In short: our EMI shielding solution is the cost-effective answer for technology that is going faster, higher and further every day.

What are the advantages of Heraeus’ solution?

Heraeus’ solution combines three major components which are key for a successful EMI shielding process. A special silver ink formula, a manufacturing machine using an inkjet process and curing equipment. This is a one-of-a-kind combination making EMI shielding cost-effective and efficient. Also, our inkjet process doesn’t only save material and costs, it also leads to a much better shielding performance.

Given the current market trend of miniaturization as well as increasingly powerful electronics, this is the way to go.

Does that mean traditional shielding methods like metal housing or sputtering might become obsolete?

Yes, absolutely.

Today, metal housing has already become obsolete, since it doesn’t meet the requirements of miniaturization. Electronics gets smaller and smaller – metal housing doesn’t work on such a tiny scale.

As for sputtering: the investment cost for our solution is only a fraction of the price of a sputtering system while providing more than three times the output. That means adding the saved investment, our inkjet process is 15 times better at one million parts per year.
