There are many myths in the field of EMI/EMC, some of which are untrue, or only partially true, or based on misunderstanding. Most of these myths came about based on attempts to balance reality (accuracy) versus the time and cost spent on successfully solving EMI/EMC issues
Obtaining increased reliability means designing properly for the intended harsh environment. Better known environmental issues include extreme temperatures, vibration, shock, humidity, salt-fog, and corrosive solvents/ atmosphere.
Multi-cavity board level shielding is an effective solution to combine many individual shields, which are in close proximity, into one PCB shielded enclosure.
Along the way CAD systems were developed by driven software engineers. As this software evolved these programs began working in the world of three-dimensional parts, offering a screen view of a complete part.
For this discussion we will focus on the photo-etching and forming process as the first step in prototyping a metal component.
