if you found a 3379 EMC is goodElectronics Technician I'm not, but I think the circuits are soldered onto the board, but they are nested on a small support for the change we need a clamp provided in this manipulation (I think the circuits are sensitive to static) so just remove the old CEM its wheelbase and place the new, attention far in the same direction, or else the module will not like it, but not at all :-)
