Publication number: 20240106045Abstract: A lead member includes a lead conductor having a first main surface and a second main surface opposite to the first main surface. The lead member includes a resin portion that covers the first main surface, the second main surface, and two side surfaces that are between both ends of the lead conductor, while exposing the both ends of the lead conductor in a first direction. The lead conductor includes a metal substrate and a surface treatment layer formed on at least a portion of a surface of the metal substrate, the surface treatment layer including chromium, oxygen, and fluorine. A moisture content of a portion of the surface treatment layer exposed from the resin portion, as measured by coulometric Karl Fischer titration at a vaporization temperature of 220° C., is 5.0 ?g/cm2 or less.Type: ApplicationFiled: February 12, 2021Publication date: March 28, 2024Inventors: Akira TSUCHIKO, Kengo GOTO, Kazuhiro GOTO, Koji KASUYA, Yoshihiro TSUKUDA, Yusuke KUREISHI

Patent number: 11877397Abstract: The printed circuit board includes, a first conductive layer including copper foil, an insulating base layer, and a second conductive layer including copper foil in this order, and includes a via-hole laminate that is stacked on an inner circumference and a bottom of a connection hole extending through the first conductive layer and the base layer in a thickness direction. The via-hole laminate has an electroless copper plating layer stacked on the connection hole and an electrolytic copper plating layer stacked on the electroless copper plating layer. The copper foil has copper crystal grains oriented in a (100) plane orientation, and an average crystal grain size of copper of 10 ?m or more. The electroless copper plating layer includes palladium and tin, and an amount of the palladium stacked per unit area of a surface of the copper foil is 0.18 ?g/cm2 or more and 0.40 ?g/cm2 or less.Type: GrantFiled: May 15, 2020Date of Patent: January 16, 2024Assignees: SUMITOMO ELECTRIC INDUSTRIES, LTD., SUMITOMO ELECTRIC PRINTED CIRCUITS, INC.Inventors: Junichi Motomura, Koji Nitta, Shoichiro Sakai, Mari Sogabe, Mitsutaka Tsubokura, Akira Tsuchiko, Masashi Iwamoto
