Gold and Silver finishes are the best for sure. Unfortunately, they can't mix the finish in a single pass. It's a two step process, which raises your cost.

Is there Anyone that works on Jot conveyors

Yep. Kevslatvin is correct. Link: http://cardinalcircuitauctions.cusauctions.com/?auction=drs&toa=bidon1&bidonlot=142&cFirstLotOnPage=23 (I do not work for them, nor do I have any vested interest. Just passing information)

Wire soldered directly on the PCB

I don't see any requirement for a ferrule on the wire. As long as your insulation clearance is twice the insulation diameter or less and the insulation doesn't interfere with the solder joint, it should pass Class 3.
