Abstract:
1. A method for encapsulating a semiconductor die with a molding compound, comprising: providing a molding apparatus that includes an upper mold chase configured for alignment with a lower mold chase, wherein the upper and lower mold chases each include a plurality of columns of cavities, each cavity for receiving a column of at least two lead frame assemblies of an array of lead frame assemblies such that each of the lead frame assemblies in a column forms rows across the plurality of columns, and wherein each lead frame assembly comprises a lead frame and a semiconductor die electrically connected to the lead frame; placing the array of lead frame assemblies into the plurality of cavities, wherein each lead frame includes at least one row of leads, and wherein the at least one row of leads is aligned along the length of the cavity; and injecting the molding compound into the each of the plurality of columns at one end of the columns such that the molding compound flows uninterrupted over each cavity and lead frame assembly in each row of each column, thereby encapsulating the lead frame assemblies.
