An electronic packaging combines features of a MAP (molded array package) and a lead frame package. The package includes an electrically conductive substrate somewhat like a lead frame package but defines a grid of conductive pads rather than a multiplicity of leads as is common with a lead frame package. An electronic chip is attached to the top surface of the lead frame, and the output terminals of the electronic chip are individually electrically connected to selected connecting pads of the lead frame grid array. Both flip chips and wire bond chips may be connected to the grid array. The channels defining the grid of connecting pads extend part way through the conductive substrate and increase in width from the top surface of the lead frame to the bottom of the channel such that the molding compound is locked in place when it cures and hardens. The grid pads are then singulated by sawing or etching channels from the bottom surface of the lead frame substrate that correspond to the channels defining the connecting pads on the top surface.
