Rainer, Thanks for the input. I had mentioned that process as a possibility to my engineers but have not tried it yet. I am glad that someone has seen it work. I don't currently have a wave solder so I would still have to hand solder but the solder mask would keep solder off the pins in either process.

The process solution was to dip the pin array into a trough of latex solder mask to the desired depth and cure. We then ran the boards through wave soldering and mechanically peeled the rubbery latex off the pins revealing clean, unsoldered gold surfaces. > Rainer G.

The pins must remain gold so at the moment I am trying to hand solder. This is a difficult process. The 0.100" spacing makes it difficult for my production personnel to solder without getting solder on the gold pins. The connectors are double row and there are two beside one another creating a four pin bank of 0.100" spaced pins. Any thoughts on how I can improve this process for the soldering personnel would be greatly appreciated.
