Dear Mr. McGregor:
I was informed of an error in my response to your question regarding
resist stripping costs. First, the cost of stripping DuPONT PM in a
feed and bleed application was misreported as $0.141/square foot. The
actual value is $0.0140/square foot. Second, the costs reported ARE per
board square foot as you requested, AND NOT per surface square foot. I
apologize for not clearly indicating the units earlier.
Regards,
Ted Stern
