Abstract
There is provided an electronic package assembly having a die attach paddle bonded to the package base by a compliant adhesive. A recessed channel formed in the base is partially overlapped by the die attach paddle. During package sealing, excess adhesive accumulates in the recessed channel, eliminating bridging of the adhesive to the leadframe.
