Thin Quad Flat Pack

Jump to: navigation, search

A thin quad flat pack (TQFP) is a type of surface-mounted package. TQFPs provide the same benefits of the metric QFP, but are thinner (body thickness of 1.0 mm) and have a standard lead-frame footprint (2.0 mm lead footprint). TQFPs help solve issues such as increasing board density, die shrink programs, thin end-product profile and portability. Lead counts range from 32 to 176. Body sizes range from 5 mm x 5 mm to 20 x 20 mm. Copper lead-frames are used in TQFPs. Lead pitches available for TQFPs are 0.4 mm, 0.5 mm, 0.65 mm, 0.8 mm, and 1.0mm.
