摘要:
Disclosed herein is a method of manufacturing a semiconductor package with a solder standoff on lead pads that reach to the edge of the package (non-pullback leads). It includes encapsulating a plurality of die on a lead frame strip. The lead frame strip comprises a plurality of package sites, which further comprises a plurality of lead pads and a die pad. The method also includes forming a channel between the lead pads of nearby package sites without singulating the packages. Another step in the method includes disposing solder on the lead pads, the die pad, or the lead pads and the die pads without substantially covering the channel with solder. The manufacturing method further includes singulating the packages.
