Handling and Assembly Recommendations
The CYG2218 products are not hermetically sealed and should not be exposed to any liquid-based rinsing processes. Clare recommends two (2) approaches. The
modem should either use a no clean soldering flux that would mostly evaporate during the normal wave soldering processes, or be soldered by hand after the rest
of the card is wave soldered.
