Abstract:
1. A winding-type solid electrolytic capacitor package structure using a lead frame, comprising: a capacitor unit including at least one winding capacitor, wherein the at least one winding capacitor has a winding body, a positive conductive lead pin extended from a first lateral side of the winding body, and a negative conductive lead pin extended from a second lateral side of the winding body, the positive conductive lead pin has a cutting surface formed on an end thereof, and the negative conductive lead pin has a grinding surface formed on an end thereof, wherein the positive conductive lead pin has a first positive conductive portion inserted into the winding body and a second positive conductive portion exposed from the winding body, and the negative conductive lead pin has a first negative conductive portion inserted into the winding body and a second negative conductive portion exposed from the winding body; a package unit including a package body for enclosing the at least one winding capacitor, wherein the package body has a first lateral surface, a second lateral surface opposite to the first lateral surface, and a bottom surface connected between the first lateral surface and the second lateral surface; and a conductive unit including a positive conductive terminal electrically contacting the positive conductive lead pin and a negative conductive terminal electrically contacting the negative conductive lead pin, wherein the positive conductive terminal and the negative conductive terminal are separated from each other; wherein the positive conductive terminal has a first embedded portion electrically connected to the positive conductive lead pin and a first exposed portion connected with the first embedded portion and exposed outside the package body, and the first exposed portion is extended along the first lateral surface and the bottom surface of the package body; wherein the negative conductive terminal has a second embedded portion electrically connected to the negative conductive lead pin and a second exposed portion connected with the second embedded portion and exposed outside the package body, and the second exposed portion is extended along the second lateral surface and the bottom surface of the package body; wherein both the second positive conductive portion of the positive conductive lead pin and the first embedded portion of the positive conductive terminal are enclosed by the package body, and both the second negative conductive portion of the negative conductive lead pin and the second embedded portion of the negative conductive terminal are enclosed by the package body.
