Also my experience - the checklist alone will not do the job. The checklist has either to be as specific that _anybody_ would understant and perfectly adapted to the design/layout where it is applied or the designer/layouter has the knowledge to correctly interpret global assertions of a less specific checklist to the specific case in front of him.
Both is not very likely to acheive. As already pointed out it is important to get the attention of the project manager and the designer/layouter. When people start to understand that EMC has an impact on: - project schedules. - product reliability. - competitivity (especially for OEMs whose products are integrated somewhere in a system the customer sells). and are aware of the fact that non-compliance can create considerable delays for the product release they are more open to your recommendations ... Managers/designers/layouters see EMC often as a nuisance and it needs a bunch of constant propaganda :-) to make them understand that they can turn it into their advantage in terms of: - preciser planning (when you plan enough time for EMC and start during the definition phase there are less surprises). - less respins, at least for EMC reasons. - less headache during the EMC qualification as there should be no big surprises when you did it right. Otherwise you will often hear the test lab saying: non-compliant what the EMC-engineer (if there is any) had already predicted before. When people are aware of the fact that EMC is worth to be considered at an early stage and start asking you about how to do it right, this is already very good. It is alway a long run ...

Usually I had to edit them after a while to say, Check design and layout with EMC engineer? Y/N or Has EMC Engineer signed off design and layout? Y/N I'm sorry if this sounds facetious, but unfortunately it's very true. The best way to control EMC issues is to beat someone over the head to get you on the list of signatories for your company's ECR/ECOs. Regards, Doug McKean Get more from the Web.
