What is a Quad Flat Pack?
A Quad Flat Pack, or QFP, is an integrated circuit package that has a relatively small lead pitch (distance between centres of the pins) and has gull wing type pins which sit on the circuit board pads like feet. A PQFP is a Plastic Quad Flat Pack. This means that the body of the packaging of the integrated circuit is made from plastic. Most QFPs have plastic bodies anyway but “PQFP” is often just shortened to “QFP”.
