A labyrinth screening can is an effective one-part board level alternative to single cast parts, or multiple cans, providing a matrix of walls and sections, for single or double-sided PCB designs. The technique can be applied to a wide range of areas, offering superior EMC performance and delivering significant time, cost and PCB real-estate savings, especially in microwave and telecommunications applications. The RFI/EMC design and PCB track layout can be simplified, board sizes can be reduced, assembly simplified, and re-work minimized.
The labyrinth technique is compatible with re-flow soldering. The designs ensure consistent solder-joint electromechanical integrity and minimize the need for hand- and re-work, speeding both production and test.
