Electromagnetic Compatibility: Cable Selection And Routing Part 5 of 5)
It is frequently observed, and more so with those who design and manufacture electronic control panels, that the overall system often fails to pass electromagnetic compatibility (EMC) tests (particularly emissions), even though the manufacturer has meticulously taken all precautions to ensure product compliance, just because they forgot one crucial aspect of EMC design—cable routing and selection.

Gerbv: The Gerber Viewer
The period between design completion and printed circuit board (PCB) manufacturing can be tricky. First, you need to completely validate the layout you have created. Once you have finalised it but the fabrication unit finds faults, the layout has to be thoroughly analysed, errors have to be spotted and corrected, and any other suggestions to be implemented, in order to get the board you dreamt of.
