Feature
26. Characteristics of an optimal seam:
* It is flat and smooth.
* It has the right dimensions (Fig. 12).
* The construction is stiff enough (Fig. 12).
* It is and will remain free of corrosion (Fig. 13).
* If possible, it is in a single plane.

27. A superior flat surface can be achieved by machining and finally grinding the top surface. This is an expensive
process and requires a stiff construction.
28. To reduce cost, the connection can be improved by using a conductive gasket, which will fill in any gaps. A gasket can also be used to seal against water or to meet other IP demands.
29. The softer the gasket, the more tolerance can be compensated and the lighter the eventual construction will be.
30. If more tolerance is allowed, a less accurate production method can be used and production becomes more
cost-effective.
31. A lighter construction can also be effected by having smaller distances between the fixings: this results in more
hinges, more locks, and more bolts. All of these extra elements result in higher cost and longer mounting and demounting times.
32. Right Dimension: It is possible to integrate an IP sealing with the EMI gasket. The IP gasket on the "water side "
protects the EMI gasket against corrosion.
