We had, on occasion, had to solder additional copper foil (solder coated) from the filters to ground. Maybe this is an option.

This filter was soldered around the perimeter of the case to the ENIG ground plane using 63/37 eutectic. The engineer is stating that electrically the filter does not appear to be adequately grounded to that plane. I am wondering if there is a better way to attach these filters? Would it be better to solder the entire bottom of the filter case to the plane? Is anyone using conductive epoxy? Liquid or sheet? I would appeciate comments.
