Abstract
Tooling for molding a packaged semiconductor device includes a clamping plate, a cavity bar, and an attachment mechanism. The cavity bar has a mold half that has a mold cavity for molding the packaged semiconductor device. The mold half has teeth and a space between pairs of adjacent teeth. The teeth and the spaces support bending of leads of a lead frame of the packaged semiconductor device. The attachment mechanism affixes the cavity bar to the clamping plate and permits the cavity bar to slide relative to the clamping plate. This sliding of the cavity bar enables proper alignment with a mating cavity bar to reduce the likelihood of resin bleed.
