TWO SIDED BONDABLE LEAD FRAME

Abstract:

A lead frame includes a first side having a first die attach pad that is bondable to a die, and a second side that has a second die attach pad that is bondable to another die. The lead frame includes multiple leads on the edges of the lead frame to connect the die. As part of a no-leads device, such as a quad flat no leads (QFN) or dual flat no-leads (DFN), one of the die attach pads is used in binding to a die, and the other die attach pad is used for thermal dissipation and mounting to a structure such as printed circuit board (PCB).
