Semiconductor Package Leads Having Grooved Contact Areas

摘要

A packaged semiconductor device (100) has a first (110) and a second (111) side, the second side including a plurality of metal terminals (120) extending to the first side. Each terminal includes an oblong groove (122) extending to the first side and ending in an orifice (123) at the first side. The terminals are made of a base metal and may have a solder-wettable surface except for the terminal surface (121) exposed at the first device side.
