A quad flat package (QFP) is a surface-mounted integrated circuit package with "gull wing" leads extending from each of the four sides. [1] 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 ...
Small outline actually refers to IC packaging standards from at least two different organizations: JEDEC: MS-012 PLASTIC DUAL SMALL OUTLINE GULL WING, 1.27 MM PITCH PACKAGE, 3.9 MM BODY WIDTH. MS-013 VERY THICK PROFILE, PLASTIC SMALL OUTLINE FAMILY, 1.27 MM PITCH, 7.50 MM BODY WIDTH. JEITA (previously EIAJ, which term some vendors still use):
Small-outline integrated circuit. This package has 16 "gull wing" leads protruding from the two long sides and a lead spacing of 0.050 inches. Early integrated circuits were packaged in ceramic flat packs, which the military used for many years for their reliability and small size. The other type of packaging used in the 1970s, called the ICP ...
In the days before the Titan vessel went into the ocean off the coast of Newfoundland, Canada, the 19-year-old university student accompanying his father on the expedition expressed hesitation ...
The gull wing, also known as Polish wing or Puławski wing, is an aircraft wing configuration with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles and from the Polish aircraft designer Zygmunt Puławski who started using this design in his planes.
Gull-wing, gull wing or gullwing may refer to: Places. Gull Wing Bridge, a bascule bridge in Lowestoft, England; Gullwing Lake, a freshwater lake near Dryden ...
The first nine aircraft had a constant-dihedral, meaning the wing had a consistent, upward angle from the fuselage to the wingtip. This design caused stability problems. "Flattening" the outer wing panels just outboard of the engine nacelles nullified the problem and gave the B-25 its gull wing configuration. [4]
Fixed floats under the wings stabilize the L-4 on water; it is operable with waves to 400 mm (15 in) high. The most unusual feature of the L-4 is the empennage arrangement: it has twin fins , mounted on the fuselage and extended forward with long, curved dorsal fillets, separated at the base by the full fuselage width and leaning slightly outwards.
