BandSorb-SC used at 24.5 GHz
Cavity resonance suppression at 24.5 GHz Introduction: Modern electronic devices are working at increasing frequencies and require a high level of separation of signals for different parts of the device. Failing to provide the correct level of separation will lead to...
Characterization of EMI shielding gaskets
Schlegel Electronic Materials, Inc. (SEM) is an active member of the IEEE P1302 Committee .This working group is in charge of the review of the methods to characterize Conductive gasket from DC to 40 GHz. Hereafter is a brief description of the main methods in use at...
Restriction of Hazardous Substances in Electrical and Electronic Equipment (EEE)
RoHS 1 DIRECTIVE 2002/95/EC RoHS 2 DIRECTIVE 2011/65/EU Supersedes RoHS 1 since Jan. 2, 2013 The RoHS 2 Directive prevents all EEE placed on the European market from containing more than 0.1 % of Pb (Lead), 0.1% of Hg (Mercury), 0.01% of Cd (Cadmium), 0.1% of CrVI...
DynaShear / DynaGreenTM Selecting the right profile
Schlegel Electronic Materials, Inc. (SEM) introduces DynaShear and DynaGreenTM an innovative EMI shielding gasket family for the shielding of modules in card/cages environment that is able to offer superior features over metal fingerstocks and current...
SEM‘s Gaskets attachment options
1. Pressure Sensitive Adhesive (PSA) The most popular attachment method is the Pressure Sensitive Adhesive (PSA). Standard PSA are non conductive and are dimensioned to not cover the entire gasket surface to ensure direct electrical contact. The constraints applied...
Non Conductive PSA (Pressure Sensitive Adhesive) Versus Conductive PSA
Schlegel Electronic Materials recommends the use of non conductive adhesives in most cases (type R). All gaskets have a PSA width recommended according to the width of the profile to ensure sufficient direct contact at the bottom of the gasket with the application....
