TQFP - Thin
Quad Flat Pack
The
Thin Quad
Flat Pack,
or TQFP,
is a surface-mount IC package with gull wing leads on all four sides
of the package
body. It is basically a thinner version of the MQFP
and LQFP.
The TQFP comes in different body sizes that range from 5 mm square to
20 mm square. TQFP
lead counts, on the other hand, range from 32 to 176.
Typical lead pitch values used by TQFP's are: 0.4 mm, 0.5 mm, 0.65 mm, 0.80 mm,
and 1.0 mm.
A typical TQFP has a body thickness of 1.0 mm.
