This removes a stub that can receive and radiate electromagnetic interference which would have been detrimental to signal transmission.

A via stub is an unnecessary part of a plated through hole (PTH) that is completely not part of the path of the signal often causing problems such as some signal reflections, change in the impedance of the circuit, electromagnetic interference (EMI), etc. In scenarios, when there is a need to transmit a signal whose frequency is greater than 1 GHz, drilling [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_eb_attr":"","_templately_pack_id":"","_templately_imported_at":"","_templately_source":"","_templately_import_session_id":"","footnotes":"","_members_access_role":[],"_members_access_error":""},"categories":[17],"tags":[114],"class_list":["post-36064","post","type-post","status-publish","format-standard","hentry","category-knowledge-of-pcb","tag-pcb-manufacturing"],"_links":{"self":[{"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/posts\/36064","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/comments?post=36064"}],"version-history":[{"count":0,"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/posts\/36064\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/media?parent=36064"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/categories?post=36064"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fs-pcba.com\/ja\/wp-json\/wp\/v2\/tags?post=36064"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
