A system of mold locks (28, 30) is formed on a heatsink (2) of a packaged semiconductor to prevent/mitigate delamination. The mold locks (4, 12) anchor a plastic mold compound (34) that forms the protective cover for the packaged semiconductor die. The mold locks (4, 12) are miniaturized to allow the positioning of them within the flag portion of the heatsink (2) and leadframe (24) such that a semiconductor die can be anchored above the mold locks (4, 12) formed within the flag portion of the heatsink/lead frame (2, 24). The miniaturized size of the said moldlocks (4, 12 do not detract from the purpose of the die attach solder (36). |
