Hi Morris,

I work as a technical consultant, application specialist for Philips EMT (SMT machine suplier).

For cost per placement complex calculation can be made. To make a easy one just to hav an idea you can use following.

Information needed: Production hours per year, Components placed per hour (net!), changeovers made per week per shift, enrgy costs, breaks per day per shift, intrest rate, years of depreciation, costs per square meter floor space, number of opperators, engineers, supervisors per shift, investment costs.

If you have all of this following calculation can be made:

Note prices are in Euro and examples!!

In this overview a lot more is in underneath like service contracts, machine efficiancy, training, updatetraining etc. etc. To make a calculation like this is very complex and concumes a lot of effort and time. I hope it helps you. If you provide me with the information then maby I can make a calculation for you.
