Abstract:
1. A method of manufacturing a leadless multi-chip electronic module including a metal leadframe having first and second chip-sized bond pads and a plurality of smaller signal bond pads, IC chips attached to upper surfaces of said chip-sized bond pads, and electrical interconnects between said IC chips and upper surfaces of said signal bond pads, the method comprising the steps of: configuring said metal leadframe such that the first and second chip-sized bond pads are oppositely disposed about an axis and separated by a space sufficient in width to accommodate a linear array of said signal bond pads therebetween, said signal bond pads being initially defined by a plurality of leadframe elements disposed in said space and extending perpendicular to said axis; covering said IC chips, said electrical interconnects, and the upper and lateral surfaces of said chip-sized and signal bond pads with an encapsulant; removing portions of said metal leadframe elements adjacent said first and second chip-sized bond pads to convert said leadframe elements into an equal number of bond pads electrically isolated from other portions of said leadframe; and soldering bottom surfaces of said chip-sized bond pads and said signal bond pads to corresponding bond pads formed on a substrate.
