Surface mount components, glue and tape?

Over on the developers board, (which I can't write to,) there was a comment about a certain chip not being available in a DIP format.

I had a thought while reading it.

Could you put circuit traces on the sticky side of scotch, or similar, tape, and use a heat gun to "solder" that to the contacts of a chip...after gluing the chip in place? Could you do so without the heat treatment?

What about using a ribbon cable and connector?

I'm not quite sure if I got you right...

but why should I do it that way and not just solder the chip directly?

It's not as difficult as it seems to be, just solder almost everything then use some desolder --I don't know what it's called... entl
