Hi Experts, I am looking at the alternatives to Solder Mask for surface high-speed interconnects, as solder mask causes impedance discontinuity. I would like to use OSP process instead of solder mask, but I have been told that OSP does not protect Copper in harsh environment. I will appreciate if you can suggest some other alternatives. Thanks. Regards Ravinder Ajmani HGST, a Western Digital company [log in to unmask] 5601 Great Oaks Pkwy.
