I am trying to gather data on the cost of the stripping
operation for primary imaging photoresists?  I would like to get $/board square
foot for:

A. Cost of operator(s) including benefits
B. Cost of equipment and depreciation amounts
C. Cost of power and cost of equipment footprint (space taken up by equipment)
D. Cost of actual stripper chemistry, either caustic or proprietary
E. Cost of rinse water
F. Cost to waste treat both spent stripper (including skins waste) and rinse
water.

I would appreciate any information you are willing to share.  Thanks for your
help.

Regards,

David R. McGregor
