Sounds to me like they are thinking since they have a gold board that it must be processed lead free. This kind of thing is happening all over since OEMs are starting to think about pb free and sending their purchasing and engineering to these semin

Mario, Thanks for your response. We are building a leaded assembly with hot air leveled Sn/Pb pads on the PCB. In one case the component is a 7.5X5.2X1.8 wire wound ferrite inductor with Au/Sn leads. The second component is an 0808 Tantalum cap,
