ABSTRACT:
An integrated circuit leadframe is specially adapted to adhere to injection mold cleaning compounds in the area of vents for an injection mold. An area of a leadframe rail that is normally positioned adjacent a mold vent is provided with apertures, surface roughness or a surface coating to cause the cleaning compound to more tightly adhere to the leadframe rail. As a result, cleaning compound flash is removed from the vents when the leadframe is removed from the mold.
