| Is there any way to implement SMT at home? | I want to assemble a prototype board of mine. | How can I hand-solder a 208-pin 0.5 mm lead | pitch PQFP -- lead-by-lead (the usual way), | or side-by-side (partial heating method)? | Alas, no SMD rework equipment available... I had been useing a PACE mini wave tip irn for reflowing QFP 160 packages with no problems, but the I had to go up to a 250 QFP with a .5 mm lead pitch like you. I was a little worried about the PACE as I was haveing some problems, so I purchased a new METCAL iron which uses RF to heat the tip. It also has what they call a hoof tip which seems to work alot better than the mini wave tip. I am now soldering the 240 pin parts better than I was with the 160 pin parts. I really love this soldering iron! I also think good flux is important. Also add solder to the side of the tip, as then the heat seems to transfer into the pins better. On prototypes I also use a heat shrink gun for reflowing on the small discreet components. I can do a whole PCB full of passives really quickly this way. I would like to get one of those OK electronics ovens though, as they look nice too.... Good luck!! Grant Petty Digital Voodoo.
