Protecting from EMI and Corrosion

An EMI shield is designed to protect electronic devices from the adverse effects of interfering energy waves. In dry environments, engineers do not need to worry extensively about corrosion. What about shielding equipment that is used in extremely damp environments? The simple answer to this question is to make EMI shield corrosion resistant. If left unprotected, it is possible for parts to rust and deteriorate, which will both harm the performance of the device. Corrosion will cause high frequency emissions that will interfere with surrounding electronic gadgets. There are several steps that manufacturers can use to help reduce the chances of corrosion. These remedies include:

EMI RFI Shielding
  1. Surface Treatments: plating or painting electronic enclosures will limit rusting, oxidation, tarnishing, and other forms of corrosion.
  2. Only use high-quality EMI gaskets: choosing the right materials for a job with lessening variations in electrochemical potential.
  3. Additional moisture sealing: salt fog or spray acting may corrode shield materials. Addition sealing prevents corrosion.
