Abstract:
1. An array of molded products, which is formed on a lead frame for making a plurality of leadless semiconductor packages, comprising: a plurality of product units each comprising a die pad, a semiconductor chip disposed on the die pad, a plurality of contacts arranged at the periphery of the die pad and electrically connected to the semiconductor chip, and a package body encapsulating the die pad, the semiconductor chip and the plurality of contacts; a plurality of dambars each being located next to the package bodies of two adjacent product units, being completely exposed from the package bodies, and connecting the contacts of the two adjacent product units; wherein each dambar has at least one groove formed therein; and wherein the plurality of product units can be individually separated by etching away the dambars through an etching process so as to form the plurality of leadless semiconductor packages.
