Abstract

The utility model discloses a plastic-coated lead frame with square tanks. The plastic-coated lead frame is composed of a plurality of lead frame units in one row. The lead frame units are interconnected through a connecting rib. Each lead frame unit comprises a heat radiating fin and lead legs. The connecting parts between the heat radiating fin and the lead legs are bent. Each heat radiating fin is provided with a carrier sheet member of which the central part is provided with a square tank. The length of the square tank is 3.08mm; the width is 3.24mm; and the depth is 0.076mm. The central part of the carrier sheet member of the plastic-sealed lead frame is provided with the square tank, and welding flux overflow can be prevented. Furthermore high stability of the frame is ensured.
