Hello everyone,
I am putting a small PCB into an SMA filter housing made of nickel-plated brass -- According to the housing manufacturer, it can withstand reflow temperatures but they would not give guidance as to the best method to solder. I have read elsewhere that soldering to electroless nickel is difficult.
Is conductive silver epoxy a viable method to bond the bottom gold-plated copper contact of the PCB to the "floor" (coax shield) of the housing? I would be using Epotek H20E, which I have experience with. In terms of electrical impedance I'm sure it will be fine, but I'm not sure about contact integrity under thermal cycling over a long timespan.
Thanks for reading
