Hi Thomas - Contact Danny Miller (319-655-3673) at the EMPF in Indianapolis IN about the possibility of using Reduced Oxide Soldering Activation (ROSA) technology for removing the oxide. A small consortia team comprised of Nortel, Allen Bradley, Rockwell, CSL Inc. SEHO USA, and EMPF just completed a DARPA contract demonstrating the restoration of printed wiring boards, flip chip assemblies, and components. The ROSA technology uses electrochemical reduction to restore solderability of a variety of surface finishes. An in-line and a benchtop ROSA system has been established at the EMPF so that any interested electronics industry companies can investigate the restoration technology with their boards and/or components issues. You can also contact me off-line if you have additional questions. Good Luck.

How can we remove the oxide layer whithout scrapping the boards? Is there an economical way to run thru a cleaning machine? I don't want to heat up the boards to reflow the solder... Your help will be highly appreciated Thomas Jacob Phone: 0041-1-306 24 07 (direct) Fax: 0041-1-306 36 40 e-mail: [log in to unmask] Internet: http://www.dyconex.com DYCONEX LTD.
