In my search for a shop to do small runs of assembling boards, I 
found one that detailed how they did P-n-P.

First, forget thru-holes.  no reason.  SMT caps and resistors are non-
polarity (most anyway) so that is a non-issue.

Anyway, they had one machine with 16 reels that pulled parts to 
another reel that was for the board.  In other words, they made their 
own single reel for a board and then the board stuffing machine only 
had to deal with one source of all chips.
