FR4 is one of the most widely used PCB substrate materials due to its good mechanical strength, stable electrical performance, and low cost. In PCB design, the FR4 dielectric constant (Dk) is a key factor affecting signal propagation, impedance control, and signal integrity. This article explains the structure, electrical properties, applications, and alternative materials of FR4. What is FR4 Material FR4 is a glass fiber reinforced epoxy laminate (Glass Fiber Reinforced Epoxy Laminate) and belongs to the flame-retardant material classification in the NEMA standard. In this name, FR stands for Flame Retardant, while 4 represents the material grade number in the NEMA classification. FR4 mainly consists of fiberglass cloth, epoxy […]<\/p>\n","protected":false},"author":2,"featured_media":5394,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-7705","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/7705","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/comments?post=7705"}],"version-history":[{"count":1,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/7705\/revisions"}],"predecessor-version":[{"id":7708,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/posts\/7705\/revisions\/7708"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/media\/5394"}],"wp:attachment":[{"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/media?parent=7705"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/categories?post=7705"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/weldomachining.com\/ja\/wp-json\/wp\/v2\/tags?post=7705"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
