Challenges and Solutions for Contacting Quad Flat Pack Devices
QPFs are leadframe based packages that are usually encapsuled in a rectangular plastic body with leads extending from four sides. For better thermal performance, some QFPs have exposed pads, typically on the bottom of the device. QFPs are industry standard sized and the leads are typically spaced at pitches ranging from 0.35 mm to 1.27 mm.
