Abstract: A leadframe strip includes a plurality of leads chemically etched into a metal sheet, a plurality of support structures chemically etched into the metal sheet, and a plurality of connecting structures chemically etched into the metal sheet. Each of the connecting structures is integrally connected at a first end to one of the leads and integrally connected at a second end to one of the support structures so that the leads are held in place by the support structures. The width of each connecting structure is at a minimum between the first and second ends of that connecting structure, increases from the minimum in a direction toward the first end, and increases from the minimum in a direction toward the second end. A method of manufacturing such a leadframe strip is also provided.

Abstract: A method of singularizing a matrix array of packages is provided, wherein the method comprises providing a matrix array of packages, wherein the matrix array is formed on a leadframe; cutting predefined leads of the leadframe by a punching process; and singularizing the packages of the matrix array of packages by a sawing process.
