[time-nuts] DMTD Question

[EWKehren at aol.com]

Before any body gets upset, I said before I used the wrong price  
calculator. The present mixer/counter takes up 4.3 by 5.3 inches, can be  separated 
into two boards and in 100 qty would be $ 9.60 with silk screen and  solder 
mask.   Bert Kehren

Does mylydia cost include sawing the  80 sets out of the 2000 square 
inches? (their website doesn't say) 

I  think the cost that was previously cited includes all the parts on the  
board.  And might include a variety of manufacturing incidentals that all  
add up, too. Some board houses automatically do the post mfr continuity 
tests,  for  instance.
