LEADFRAME data sheet LQFP Features: Low Profile Quad Flat Pack (LQFP) Packages: Amkor offers a broad line of LQFP IC packages designed to provide the same great benefits as MQFP packaging with a 1.4 mm body thickness. This allows IC packaging engineers, component specifiers and systems designers to solve issues such as increasing board density, die shrink programs, thin end-product profile and portability.
