Diode package having improved lead wire and manufacturing method thereof

摘要

According to the present invention, there is provided a diode package in which a diode chip is sealed by a molding compound and a lead wire connected to the diode chip is led outside the molding compound, wherein the lead wire is divided into an upper lead wire and a lower lead wire, both lead wires each being formed in a long, flat plate and having a first stage and a second stage, both stages being opposite from each other, the upper side of the diode chip is attached to the lower side of the first stage of the upper lead wire, the lower side of the diode chip is attached to the upper side of the first stage of the lower lead wire, and the second stage of the upper lead wire and the second stage of the lower lead wire are led out in the lateral direction of the molding compound.

主权项

1. A diode package, comprising:
a diode chip; a molding compound, wherein said diode chip is sealed by said molding compound; a lead wire connected to the diode chip, said lead wire being led outside the molding compound, wherein the lead wire is divided into an upper lead wire and a lower lead wire, each of the upper and lower lead wires being formed in a long and flat plate and having a first stage and a second stage, both stages being opposite from each other, an upper side of the diode chip is attached to a lower side of the first stage of the upper lead wire, a lower side of the diode chip is attached to an upper side of the first stage of the lower lead wire, and the second stage of the upper lead wire and the second stage of the lower lead wire are led out in the lateral direction of the molding compound, wherein the first stage of the upper lead wire has a hemispherical contact groove which protrudes downward, and the hemispherical contact groove has a through hole in the center thereof.
