In Reply to: Do You Believe The Price Simply Equals The Sum Of The Prices Of The Parts Involved? posted by thetubeguy1954 on October 26, 2006 at 09:41:52:
A 33 dollar driver...times 50, is 1,650 dollars in drivers.Now, for correct operation, the drivers have to be matched. So, say 75% fallout from a batch if you select transfer function accuracy of 1%. (ok, they can be binned).
Test of function, say 10 minutes per driver, that's 200 drivers checked at initial run, 2000 minutes of test at a dollar per minute (underestimating labor and overhead of the labor).
First run costs 6600 in drivers, 2000 for driver binning..8600 dollars. Subsequent runs will be 500 dollars plus 1650, 2K per in medium quantity.
Then there's building and final burnin and test. OOPS, burn in has to occur prior to binning..sorry bout that. Say, 5 minutes per driver to load and unload the rack, 1000 dollars. That puts initial at 10K so far, subsequent at 2500 per.
Assembly, figure 8 hours at 100 per hour, 800 bucks plus materials, an even 1000.
So, first set at 11 thousand dollars, scales to 3500 per.
The first set has a markup around 70%...that's pretty small, and wouldn't support business.
Production quantities can take it to a factor of 5 markup, this is closer to production viability as long as there is a good quantity of orders.
It doesn't get much better if one assumes drivers wholesale, but it helps.
Figures just for S + G of course, some of my assumptions are not complete.
Cheers, John
