A very relevant example is the STMBL servo driver boards I made. (not my design, I just wanted some to use) The cost-per-part of the components is almost constant with volume. It drops a bit, but not enough to really matter. PCB setup and PCBA is pretty much flat after 100 units. Here are the actual numbers from my STMBL purchase: https://docs.google.com/spreadsheets/d/1h-26i7gXVHMsfAxbrWg1JodXoI41dRo-FZ9OmJNwTtk/edit?usp=sharing (you need the "quotes" tab.) I think that for x50 quantity PCB placement is about 1¢ per part. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
