摘要:
A method of forming a capacitor includes the steps of: forming an anode with an anode wire extending there from; forming a dielectric on the anode; forming a cathode layer on the dielectric; providing a substrate comprising at least one via and at least two connectors; inserting the anode wire into a first via; forming an electrical connection between the anode wire and a first connector of the connectors; and forming an electrical connection between the cathode layer and a second connector.

A solid electrolytic capacitor body is attached to lead frame by a secondary adhesive and a method for forming the capacitor assembly. The assembly consists of a chip that has conductive adhesive formed on the cathode surface. Secondary adhesive is placed adjacent to the conductive adhesive. Lead frame is attached to these adhesives and the adhesives are cured simultaneously. Secondary adhesive can be thermally or UV cured. The solid electrolytic capacitor formed by this method showed improved adhesion between lead frame and capacitor body.
