Electronic device with external terminals and method of production of the same |
摘要 |
A multilayer ceramic capacitor with external terminals having terminal electrodes and external terminals of the electronic device body electrically bonded through a solder layer, wherein the solder layer is comprised of an Sn-Sb high temperature lead-free solder, the ratio between the Sn and Sb in this solder layer is, by ratio by weight percent, in a range of Sn/Sb = 70/30 to 90/10, and the solder layer and terminal electrodes are formed between them with a diffusion layer formed by diffusion of a conductive ingredient of the terminal electrodes into the solder layer.
