Package Lead Design with Grooves for Improved Dambar Separation

The invention relates to a package lead design with grooves for improved dambar separation. The lead frame includes a die pad, a first lead extending away from the die pad, a peripheral structure mechanically connected to the first lead and the die pad, and a first groove in an outer surface of the first lead. The first groove extends longitudinally along the first lead away from the die pad. 本发明涉及一种具有用于改善的阻挡条分隔的凹槽的封装引线设计。本发明公开了一种引线框架，其包括：管芯焊盘；第一引线，所述第一引线远离管芯焊盘延伸；外围结构，所述外围结构机械地连接到第一引线和管芯焊盘；以及第一凹槽，所述第一凹槽在第一引线的外表面中。第一凹槽远离管芯焊盘沿着第一引线纵向延伸。
