Unisem's Etched Leadless Packages (ELP) delivers design flexibility, increased density and a reduced footprint. Based upon our patented technology, the advanced ELP framework leverages our world-class selective Etching process, allowing tight integration of multiple I/Os into a reduce area. The ELP has also received approval from JEDEC (MO 247) as a standard in multi-row leadframe packaging.
