Hi there! I will appreciate any help from an experienced lister about techniques for manual soldering this kind of chip. I got experience on manual soldering of some types of SMD IC's (using Chem-Wik rosin), but this one has a *very little* space between pins. The mechanical specs are: * Package: 144 pin (4x36 pin) LQFP (Low-profile QFP) * Distance between center of pins: 0.5 mm. * Pin width: 0.17 mm. Probably it can be done using flux or solder paste, but i have no detailed idea about application of these techniques. And yes, the chip is available only with this package...
