Quad Flat Pack (QFP) components have four sides with leads extending from the component body on all four sides. QFP components come packaged in trays or on tape and reel to protect the component leads that can be easily damaged. An important measurement for QFPs is coplanarity. When the first lead from the component is placed on the PCB board coplanarity is established. Coplanarity ensures the last lead can be placed on the board. The standard for QFP coplanarity is ±4 mils. Lead-free versions of QFPs are now available. Please call for additional information.
