In one embodiment of the invention, a lead-frame is designed for use in IC packages such as those conforming to the TO 220 standard or other standards for power packages. The device areas of the lead-frame are arranged in columns, and each column is molded so as to expose a portion of the leads. The device areas can then be cingulated by sawing, as in conventional QFN packages. In this manner, packages conforming to power package standards such as the TO 220 standard can be produced much quicker and cheaper than they can in conventional trim and forming methods.
