There is a lot that rides on the proper construction of EMI gaskets. These vital equipment ensure the safe operation of electronic devices, which can sometimes be the difference between life and death. If essential medical and military equipment fails, it puts people’s lives in danger. The EMI gasket needs to be designed based on several factors to ensure the highest performance and safety level.
EMI Gaskets
Below, we want to highlight some of the most important factors when designing EMI gaskets. Designing particular parts is more manageable when you partner with experts in electromagnetic interference protection.
The first step in the design process is choosing a filler material. The material should be picked on more factors than price because each option has different pros and cons, meaning they should not be used interchangeably. The most commonly used materials include Silver, Nickel, and Aluminum. For precise demands, such as nickel graphite or silver copper, alloys are also used. Choosing the wrong material during the design process costs time and money because the gasket cannot provide complete protection.
Beyond picking a material, you also need to consider the following:
- The total force of compression on the gasket
- The design needs to consider the grooves of the gasket (it is best to stay out of grooves when designing form-in-place gaskets)
- Sloping surfaces are a considerable problem because it makes the dispensing process difficult
- When possible, use vertical integration
- Make sure there is ample distance between EMI gaskets and ferrous materials
Time and care should be taken when designing EMI gaskets. For help getting through the process successfully, you should not hesitate to give our talented and dedicated team a call. We know EMI protection, and we offer custom and affordable solutions.
