Hello all! Installing surface mount devices of the type Paul is suggesting is really no more difficult than many of the mods we make to existing pcb's. With the pads of the pcb pre-tinned, one simply aligns the IC and holds it in place with gentle pressure from a tool like a tweezer or small screwdriver. This just keeps your fat fingers away from the soldering iron. Heat one corner leg of the device until the solder melts-just a tack joint. Then do the leg on the opposite corner. Lastly, heat each joint while maintaining a light downward pressure and you're done. A simple tool can be made to apply downward force while leaving both hands free. I read about it some months ago in QST (the radio amateur's magazine) and I will post the article if I find it and there's interest. It resembles a tonearm for a record player (those too young to remember records should do a search on the 'net!)and should be adaptable to any work station. Paul, if you design it-they will come...
