Extracted from the Wikipedia article Quad flat package.
A quad flat package (QFP) is a surface-mountedintegrated circuitpackage with "gull wing" leads extending from each of the four sides. Socketing such packages is rare and through-hole mounting is not possible. Versions ranging from 32 to 304 pins with a pitch ranging from 0.4 to 1.0 mm are common. Other special variants include low-profile QFP (LQFP) and thin QFP (TQFP).
