Abstract: A lead frame for mounting LED elements includes a frame body region and a large number of package regions arranged in multiple rows and columns in the frame body region. The package regions each include a die pad on which an LED element is to be mounted and a lead section adjacent to the die pad, the package regions being further constructed to be interconnected via a dicing region. The die pad in one package region and the lead section in another package region upward or downward adjacent to the package region of interest are connected to each other by an inclined reinforcement piece positioned in the dicing region.

Abstract: A lead frame includes a die pad and a plurality of lead portions each including an internal terminal and an external terminal. The external terminals of the plurality of lead portions are arranged in an alternately staggered form such that the respective external terminals of a pair of lead portions adjacent to each other are alternatively located on an inside or an outside. A lead portion has an inside region located on the inside of a first external terminal, an outside region located on the outside of the first external terminal, and an external terminal region having the first external terminal. The inside region and the outside region are each formed thin by means of half etching. A maximum thickness of the outside region is larger than a maximum thickness of the inside region.
