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. Bob Robert Barr Manufacturing Engineering Formation, Inc.
