I was talking with a friend of mine the other day about component footprint verses component body size. He said the footprint is the body size, it this true? I always saw them as being different.

we need a soldering nozzle for this package that can be placed by the rework machine on a pads of this qfp (to make the pads planar) and then send a hot air and after the solder joint melt stop the hot air and pull up the nozzle do we have such mach

Wouldn't it be cheaper to by quality parts? Most repair operators can solder a QFP 208 with a regular soldering iron, eyes closed and hands behind their back. If you are just touching up the leads because of co-planer leads, a regular iron is all

Has anyone used lead free 99C bar solder/paste? Looking for more information other than what the manufacturers give you. Thanks
