Gold embrittlement of solder joints has been a concern for many decades. SEM Lab, Inc. supports evaluation for this condition. Gold embrittlement can be avoided by careful solder joint design and knowledge of the causes of this condition. https://s

Assuming that you are going to solder them into a board rather than socket them, yes. The thickness of the gold plating in this application will usually make up a large enough percentage of the total joint to threaten enbrittlement. Use a small sol

The papers I've read suggest that we need to be concerned if the weight percent of gold in the finished joint exceeds 3%. You might want to do the calculations to see where you stand, before you set up a process to "tin" the leads. If you find that
