Title (EN) INDUCTOR COMPONENT AND MANUFACTURING METHOD THEREFOR
(FR) COMPOSANT DE BOBINE D'INDUCTION ET SON PROCÉDÉ DE FABRICATION
(JA) インダクタ部品およびその製造方法
Abstract:
(EN) The present invention improves the characteristics of an inductor component by lowering the resistance of an inductor electrode. An inductor component 1a comprises a resin layer 3 and an inductor electrode 6, wherein the inductor electrode 6 has upper side wiring boards 8a, 8b that have connection sites 7a, 7b, a lower side wiring board that is in contact with the upper side wiring boards 8a, 8b via the respective connection sites 7a, 7b, and metal pins 9a, 9b. The connection sites 7a, 7b are formed by bending one end section 80a, 80b of each of the upper side wiring boards 8a, 8b. Because, in this case, the inductor electrode 6 is formed from the wiring boards 8a-8c and the metal pins 9a, 9b, all of which have lower resistance values than conductive paste or plating, the resistance of the entire inductor electrode 6 can be lowered, thereby improving the characteristics of the inductor component 1a.
(FR) La présente invention améliore les caractéristiques d'un composant de bobine d'induction en abaissant la résistance d'une électrode de bobine d'induction. Un composant de bobine d'induction 1a comprend une couche de résine 3 et une électrode de bobine d'induction 6, laquelle électrode de bobine d'induction 6 présente des cartes de circuit imprimé côté supérieur 8a, 8b qui ont des sites de connexion 7a, 7b, une carte de circuit imprimé côté inférieur qui est en contact avec les cartes de circuit imprimé côté supérieur 8a, 8b par l'intermédiaire des sites de connexion 7a, 7b respectifs, et des broches métalliques 9a, 9b. Les sites de connexion 7a, 7b sont formés par courbure d'une section d’extrémité 80a, 80b de chacune des cartes de circuit imprimé côté supérieur 8a, 8b. Car, dans ce cas, l'électrode de bobine d'induction 6 est constituée des cartes de circuit imprimé 8a-8c et des broches métalliques 9a, 9b, tous ayant des valeurs de résistance inférieure à celles d'une pâte conductrice ou d'un plaquage, la résistance de la totalité de l'électrode de bobine d'induction 6 peut être réduite, ce qui améliore les caractéristiques du composant de bobine d'induction 1a.
(JA) インダクタ電極の低抵抗化を図ることによりインダクタ部品の特性の向上を図る。 インダクタ部品1aは、樹脂層3とインダクタ電極6とを備え、インダクタ電極6は、接続部位7a、7bを有する上側配線板8a、8bと、接続部位7a、7bを介して上側配線板8a、8bのそれぞれに接する下側配線板8cと、金属ピン9a、9bとを有する。接続部位7a、7bは上側配線板8a、8bの一方の端部80a、80bを屈曲させることにより形成される。この場合、インダクタ電極6が、いずれも導電性ペーストやめっきよりも抵抗値が低い配線板8a~8cおよび金属ピン9a、9bとで形成されるため、インダクタ電極6全体の低抵抗化を図ることができ、これにより、インダクタ部品1aの特性を向上することができる。
