I spent a good deal of time Friday trying to find out. So far, they're
telling me that the study was funded by the government and can't be
released. I'll keep digging since I thought the industry in general had
come to the same conclusion that in today's world of better processes and
materials, along with process control, etchback is a liability more than an
asset. Many high reliability customers have reduced the maximum etchback
allowed on their product for that reason, but have not yet allowed desmear
because they don't want to invest time to qualify a supplier's desmear
process.

Desmear
Hi Tom,
Having been around a long time is both a curse and a blessing.
Are the whate Paper data available?
