Laird Technologies' EMI Experts Author Article for IN Compliance Magazine
Article Discusses EMI Shielding for Medical Devices and the Effects of Cleaning Solutions on Material Performance
The article, titled "Design and Selection of Shielding Gaskets for Medical Devices and the Effect of Cleaning Solutions on Material Performance," discusses the results of a study conducted on typical EMI shielding gaskets that were exposed to frequent and aggressive cleaning and sterilization regimens using typical cleaning solutions. The article then examines design considerations in medical devices for protecting the EMI gaskets from cleaning solution exposure.
There are four factors to consider in the service life and performance of an EMI gasket: (1) the number of times the joint is opened and closed; (2) the severity of gasket deformation when the joint is closed; (3) the presence of chemicals and fluids, ozone aging and temperature extremes; (4) inadvertent damage to the gasket during installation and maintenance.
Understanding the environment in which these medical devices are used is important in preventing and addressing EMI issues. The design of the device needs to be one which maintains proper EMI shielding over time in the expected conditions of use. Good design, good materials, and an understanding of use can lead to high reliability in EMI solutions for public health and safety applications.

About IN Compliance Magazine
IN Compliance Magazine's mission is to supply the latest news and information to electrical engineering professionals keeping them informed and educated on requirements to design, produce, and market their products around the world.
Our roots run deep in the community of electrical engineering professionals whose primary concern is the regulatory compliance of their companies' products. Our team was the driving force behind our predecessor, Conformity®1 magazine. When the decision was made to shutter Conformity in March of 2009, our team got together and committed to continue supporting our community.
August 2009 brought the launch of our new publication, IN Compliance Magazine. Our Premiere Issue was released at the IEEE EMC Symposium in Austin, Texas where we were welcomed back by friends and supporters anxious for the informational needs of the compliance community to once again be filled. Starting with the January 2010 issue, we resume our mission by publishing monthly issues of IN Compliance Magazine, providing the latest industry news on our website www.incompliancemag.com and through semimonthly eNewsletters. We are proud to continue supporting our community as their preferred source of regulatory compliance information.
