There are a variety of peroxide/sulfuric acid-based materials on the market (Alpha, MacDermid, LaPorte/Electrochemicals, Shipley) that seem to be very well received in Europe.  There is also a formic acid-based material from MEC  that apparently is widely used in Japan.  These microetches have additives which increase the surface topography and in some cases leave a lightly "oxidized" surface which can range from pinkish to brownish, based on the examples I have seen.

We use some Durabond and some oxide in this facility; we will be installing afully-conveyorized oxide replacement process in the next 8 weeks, as neither of the existing processes will work with the type of parts that we are attempting to manufacture.

We are in the process of selecting a new line for prelamination, and we
would like to know of other proven alternatives to Oxide/Durabond.
We also would like to have a fully conveyorized system capable of
linking to conveyorized AOI and to Lamination.
Thank you for your help
