Gasket Junction Design

Ideally, gasketing surfaces should be recessed and rigid to enclose the gaskets completely. At the same time, the gasket design should be as conductive as possible. It is important to remember that the metal surfaces that are mating with the gaskets should be non-corrosive. When interaction with the environment is inevitable, reaction products must be either easily penetrable (mechanical abrasion) or electrically conductive. Incorrect mating surfaces are common causes of gasket design failure. When designing gaskets, care must be put into the selection of materials as well as the mating surface. Both should be treated with the same care.

A gasket is needed most when imperfect surfaces exist. The worse off the mating surface is, the more crucial becomes the function of the gasket. Gaskets mitigate the expensive cost of creating perfect surfaces. Designing gaskets require individuals to contemplate two main factors: economics and performance. Do not cut corners and neglect the design of flange surfaces.

Conductive elastomer gaskets make reliable and robust EMI seals because they can create even conductivity throughout the entire gasket-flange interface. At this design stage, efforts should be focused on picking a flange that will be stiff and consistent with the construction that is used.
