Electronic component
View Patent ↗An electronic component comprises an element body, an external electrode, and an insulating resin coating layer. The element body has a pair of end faces opposed to each other, a pair of principal faces extending so as to connect the pair of end faces and opposed to each other, and a pair of side faces extending so as to connect the pair of principal faces and opposed to each other. The external electrode is formed so as to cover at least a partial region of the principal face and/or a partial region of the side face and has a plating layer comprised of Sn or an Sn alloy. The insulating resin coating layer covers at least the portion of the external electrode formed so as to cover the side face.
1. An electronic component comprising:
an element body having a pair of end faces opposed to each other, a pair of principal faces extending so as to connect the pair of end faces and opposed to each other, and a pair of side faces extending so as to connect the pair of principal faces and opposed to each other;
an external electrode formed so as to cover at least a partial region of a first principal face of the pair of principal faces and a partial region of a first side face of the pair of side faces and having a plating layer comprised of Sn or an Sn alloy; and
an insulating resin coating layer covering at least a portion of the external electrode formed so as to cover the first side face, the insulating resin coating layer functioning as a solder resist layer, a portion of the external electrode formed so as to cover the first principle face being exposed from the insulating resin coating layer,
wherein the insulating resin coating layer is comprised of a thermosetting insulating resin, a UV-curable insulating resin, or a thermosetting insulating resin introduced in a UV-curable insulating resin; and
wherein a portion of the first principle face is exposed from both the external electrode and the insulating resin coating layer.
2. The electronic component according to claim 1 , wherein the external electrode is formed so as to further cover a first end face of the pair of end faces; and
wherein the insulting resin coating layer further covers a portion of the external electrode formed so as to cover the first end face of the pair of end faces.
3. An electronic component comprising:
an element body having a pair of end faces opposed to each other, a pair of principal faces extending so as to connect the pair of end faces and opposed to each other, and a pair of side faces extending so as to connect the pair of principal faces and opposed to each other;
an external electrode formed so as to cover at least a partial region of a first principal face of the pair of principal faces and a first end face of the pair of end faces and having a plating layer comprised of Sn or an Sn alloy; and
an insulating resin coating layer covering at least a portion of the external electrode formed so as to cover the first end face, the insulating resin coating layer functioning as a solder resist layer, a portion of the external electrode formed so as to cover the first principle face being exposed from the insulating resin coating layer,
wherein the insulating resin coating layer is comprised of a thermosetting insulating resin, a UV-curable insulating resin, or a thermosetting insulating resin introduced in a UV-curable insulating resin; and
wherein a portion of the first principle face is exposed from both the external electrode and the insulating resin coating layer.
