Thin Quad Flat Pack (TQFP) is a type of SMD package. Components of this type provide the same benefit of the metric QFP package, but are thinner (body thickness of 1.0mm) and have a standard lead-frame footprint (2.0mm 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 x 5mm to 20 x 20mm. Copper lead-frames are used for the TQFP package. Lead pitches available for TQFP package are 0.4mm, 0.5mm, 0.65mm 0.8mm and 1.0mm.
