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

Subject: [TN] Attaching Microwave Components
Hello Tec Netters,
We are de-buging a new circuit board containing a microwave filter
operating
in the 2 - 3 Ghz range. 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.
Thanks,
Jim Kittel
