Patent ID: 7049166

Claim:
A method for making an integrated circuit (IC) package with an exposed portion of the IC, the method comprising: providing a mold including first and second mold portions, the first mold portion carrying a mold protrusion defining an IC-contact surface with peripheral edges and a bleed-through retention channel positioned inwardly from the peripheral edges; closing the first and second mold portions around the IC and injecting encapsulating material into the mold to form the IC package with the exposed portion adjacent the mold protrusion and while the bleedthrough retention channel retains encapsulating material bleeding beneath the peripheral edges of the IC contact surface; controlling pressure applied by the IC-contact surface to the IC when the first and second mold portions are closed around the IC, wherein controlling pressure comprises mounting the IC on a leadframe having resilient portions to resiliently accommodate downsetting of the IC as the IC-contact surface contacts the IC; and releasing the IC package from the mold.
