QFP, or Quad Flat Packages have 4 sides of gull wing leads that stick out. TQFP and PQFP stand for “Thin” and “Plastic”, respectively. This board also features 20 places for 0603 packagea (.06x.03″), some thru hole passive components, and 6 ground holes connected to a copper plane on the bottom side. The solder filled troughs are slightly inset below the surface, which helps to hold the chip leads in perfect position. No microscope is necessary for alignment. The only requirement is a tip slightly smaller than the lead size. Recommended tip temperature is 750 – 800 degrees F. This board is RoHS Compliant with lead-free solder. detailed pdf Manufacturer’s part number: 202-0011-01 Video demonstrating hand soldering of a QFP package:
