more compact and densely integrated, the reduced distances between components and traces have made it a common problem for noise from power circuits to couple with control circuits, and vice versa. This significantly degrades EMC performance. An effective countermeasure to this issue is to apply shielding to each circuit block to suppress this noise coupling.<\/p>\n<p>In this study, we present an effective method for suppressing noise coupling from power circuits, specifically in the low-frequency range of 10 kHz to 30 MHz. Based on our experimental results, we demonstrate how to achieve effective separation by grounding the metal enclosure and the board ground using metal spring materials.<\/p>\n<p><em>Eric Ekkapon-san \u2013 Kitagawa on behalf of Telerex<\/em><\/p>\n<p><a class=\"header__button button\" href=\"https:\/\/fhi.nl\/en\/emc-esd-event\/emc-esd-event-2025-programma\/\">Back to the program overview<\/a><\/p>\n<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":56,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"footnotes":""},"branches":[],"events":[533],"secretariat":[41],"categories":[],"themes_tax":[],"class_list":["post-72212","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.8 -
