Grant The solution to soldering problems with immersion gold boards is: find a supplier that can control his/her process. Electroplated gold over nickel is a very reasonable process. Billions of wire bound boards use it evry year.

Discrete wiring and flat ribbon cabling. Fairly simple cables (connectors include: DF-11, IDC, D-SUB), proper crimping is probably the most difficult concept. But unfortunately is often overlooked.

The connections at the heaters are also a known problem area. You may need to put new connectors on the wires. Jerry

I would to ask on what do you call on the color green contamination found on the soldered units. Whe i soldered some units after few days there was a color green on the wires. what do you call on this contamination?

You would probably have better luck posting your request with the Wire Harness Manufacturers Association at this link: http://finance.groups.yahoo.com/group/whma/

Is this Al tape you guys are talking about insulated? If not, and if it jumps the tc wires, it'll effect your values.

85% are exempt from the RoHS directive. Doesn't make a lot of sense but that wasn't your question.

Your best bet would be to browse through you current solder suppliers catalog and pick your alloy. Most of them have a list of alloys and their melting points as well as what form they can be supplied in.

Multicore make a HMP alloy liquidus at 298 degrees, Pb93Sn5Ag2.Ive used it to attatch thermocouples but they're difficult to solder as they dont wet.

Q: Is anyone aware of any solderability issues that may exist when soldering beryllium copper parts (in this case spring contacts) to a PCB using standard Pb63/Sn37 solder paste/wire?
