Don’t miss reading PFC’s informative article Flex Circuit Shielding Design Options recently featured in Flex007An excerpt of the article is below with a link to the complete, published article at the bottom.

 

In December of 2014 I visited the Radiological Society of North America (RSNA) conference in Chicago. As you can imagine, MRI and X-ray equipment filled the convention center. Attending the show gave me the opportunity to speak to radiology designers. Since the equipment they are designing “radiates” with waves of electrons, the underlying electronics have to be super protected for fear of interference. When discussing flex designs, EMI and shielding circuits is the number one design concern.

Shielding may not be your company’s number one design concern when thinking about your interconnect designs. But if you have to shield circuits for EMI, then you will need to depend on your supplier to assist you with their favorite shielding technique and experience.
