Abstract
There are provided an electronic component having external electrodes and a method for manufacturing thereof for which treatment of the wastewater is not needed and has electrolytically plated layers which are substantially plated only on the conductive layers but not on the ceramic surfaces. In the method for manufacturing the electronic component, an activation treatment is performed in which palladium is deposited on a conductive layer on the electronic component, and then electrolytic Ni plating and electrolytic solder plating are performed sequentially.
Claims7
An electronic component having external electrodes, the external electrodes comprising:
- a first layer including an oxidizable metal as a major component;
- a second layer disposed on the first layer and including a metal having smaller ionization tendency than the oxidizable metal;
- and
- at least one electrolytically plated layer including a heat resisting layer and a solder wettable layer.
A method for manufacturing an electronic component having external electrodes, the method comprising:
- forming a first layer on a body of the electronic component, the first layer including an oxidizable metal as a major component;
- forming a second layer on the first layer by utilizing cations of a metal having a smaller ionization tendency than the oxidizable metal;
- and
- forming at least one electrolytically plated layer having a heat resisting layer and a solder wettable layer.
