OK, Jerry, sounds plausible - but 1/2 oz is still 'way cheaper than 1/4 oz with aluminum carrier that has to be stripped off. Would the 1/2 oz profile meet your objections? Thanx, Fred J. >>> JSSallo <[log in to unmask]> 03/23/98 02:19pm >>> Fred I am not up to date on new methods and equipment. Years back I was involved in a program to "shave" the copper. Unless there are some major improvements in uniformity, I advise against it. Remenber that when you are finished, the copper will still have the tooth of one ounce copper, and will require overetching compared to "real" 9µ foil. I would be glad to discuss history with you.
