PQFP - Plastic Quad Flat Pack  

           

The Plastic Quad Flat Pack, or PQFP, is an IC package with leads extending from all four sides of the package body. PQFP's are predominantly square in shape, although rectangular variants do exist. The PQFP is just one of the many types of the quad flat pack (QFP) package.

 

The PQFP comes in many body sizes, with lead counts ranging from 32 to 208. Lead pitch values used by PQFP's range from 0.4 mm to 1 mm. Typical PQFP body thickness varies from 2 mm to 3.8 mm. Lead coplanarity is very critical for PQFP's, and should be within 4 mils for this package.
