QFP (Quad Flat Package) is a surface-mounted integrated circuit package with "gull wing" leads extending from each of the four sides. Its “gull wing” lead shape can provide better operability. In addition, with its high pin count character, QFP can also provide higher reliability. Therefore, it is widely used in all kind of electronics product. QFP package derivate into LQFP (Low Profile QFP) and TQFP (Thin QFP). QFP package is widely used in MCU, monitor and communication IC. CWTC can provide below QFP lead frame SPEC.
