We are looking to mount a GPS receiver that is constructed similar to an LCC
type package. That is, it is an FR-4 board with gold terminations on the
side. These terminations also wrap under the board about .035". The
underside of the board has traces covered with soldermask. Has anybody ever
used a package such as this with water soluble flux cleaned with DI water
(we have an in-line system)? When soldered, there is virtually no standoff
of the receiver. Is there a danger of flux being trapped underneath and
causing potential problems? Or is this a non-issue. I am thinking that
resistors and capacitors have terminations that wrap underneath and they do
not seem to be a problem. Thanks.
