Flexible Circuits and EMI

As processors and computer chips in electronic devices are getting smaller, the need for proper EMI shielding is critical.  Without the help of shielding, EMI and RFI would leak out of a device, and then it will affect the performance of other nearby electronics. EMI can cause small problems, such as radio and cell phone static, but in more severe cases it can cause machinery to fail. This could be an absolute tragedy in a hospital setting.

Newer devices have begun to incorporate flexible circuits into product designs. All flexible circuits must include some form of EMI Shielding. When it comes to building flexible EMI shielding, there are two basic requirements to consider. The first is conductibility and the second is groundability. After the two above are considered, it is wise to think then about the overall degree of flex.

The three most commonly used materials for creating flexible EMI Shielding are, solid copper, crosshatched copper, and conductive silver. Speaking with trained professionals will help you pick the best possible materials for your shielding needs.

Without the proper shielding, an electronic device will most likely leak EMI and RFI into the surrounding work. This will have an effect on other devices, which will ultimately hurt your company’s bottom line.
