How to manually solder a QFN chip with a hot air gun
Aug 14 2009 · As with reflow soldering of SMT parts like this QFN IC you need to put down solder paste on the pads and also several paste dots on the ground pad on the PCB. Then place the QFN IC onto the paste and heat with a hot air gun with the appropriate 4-sided air funnel attachment. The QFN should suck down into position as the solder paste melts.

What is HASLHot Air Solder Leveling PCB Directory
HASL (Hot Air Solder Leveling) is a metallic surface finishing technique which is performed on the outermost layer of the PCB board to protect the exposed copper surfaces like tracks until the component placement and soldering is completed. The HASL coating is composed of Solder with 63 Tin and 37 Lead and during the assembly process this coating gets dissolved with the soldering material.
