| titleOfInvention | lead frame |
| abstract | The utility model discloses a lead frame, comprising a frame main body and a plurality of lead units, the plurality of lead units are arranged in multiple rows at intervals along the length direction of the frame main body, and are arranged in multiple rows at intervals along the width direction of the frame main body, Wherein, each lead unit includes an upper pin and a lower pin, the upper pin includes a first pin and a second pin, and the lower pin includes a third pin, a fourth pin and a fifth pin The fourth pin includes a body end and a pin end, the body end and the pin end form a cross-shaped structure, the pin end is located between the third pin and the fifth pin, and the upper part of the body end is located between the first pin and the pin end. Between the second pins, both ends of the body end are located between the upper pin and the lower pin. The lead frame improves packaging density and packaging yield. |
