For all the people with large number of chips, the most feasible option would be a double density board with 20 Chips at about 100eur.
Even larger boards would pose problems that I don't want to face, doing such a time-constrained project.
This would be awesome, for 100 chips I'd much rather deal with 5 units then 10, and it would probably be much faster for you to assemble and test.
Thanks Burnin.
