I saw your note to the technet and we at IBM Microelectronics in Endicott build product similar to the product you described but we are not Mil-spec approved and have no plans to become Mil-spec approved. If you are still interested, please contact Ed Frankoski at 607-755-5714. Irv Memis --------------------------------------------------------------------------- Hello! I'm hearing a lot about hybrid laminate construction, the bonding of PTFE RF circuit boards to an epoxy board, be it FR-4 or polyimide. We are considering combining both RF and digital circuits on the same board, and thought that this might be a solution. I'm looking for board fab houses (MIL qualified, please) which offer this technology. I'd also appreciate hearing from anyone who has any experience with this approach. Thanks, Jim Marsico
