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

. One example of how the interactions between solder and surface finish can affect solder joint integrity is the potential formation of brittle gold/tin intermetallic compounds (IMCs
