Design Review
In general, EMI problems come from numerous sources and manifest themselves in many ways. The recommendations described below have a cumulative effect when combating EMI problems. In our experience, we have found that when a design incorporates changes such as those discussed below, emissions from the design are significantly reduced. Usually, we cannot point to a single change that contributed to the reduction of EMI, but instead have found that the improvement is due to an additive effect of all the recommendations that are incorporated. Thus, we recommend that all the following modifications be implemented. When a constraint prevents a specific modification from being implemented, Rhein Tech Laboratories (RTL) and our client's engineers would discuss the recommendation/modification and constraints, and investigate other modifications that accomplish the same goal as the original recommended modification.

The recommendations presented by RTL to our clients are specific to the particular product system design, but the guidelines can be applied to the other PCBs systems. Specifically, most Artwork would benefit from the type of recommendations presented below. This presentation highlights the benefits of the kind of services that RTL can provide for its clients.
