@Vernon Barry posted:Yes, per official ESD guidelines and standards you may in fact have a hard grounded surface workbench. Yes, I fully acknowledge that in theory with trains, we are dealing with lower voltage power, but at the same time, we may have tools, soldering irons and so forth typically at 120V AC. I have had an AC soldering iron (actually a desoldering iron from Radioshack) internally fail and short to AC at the tip. I destroyed a the very computer once I am typing this reply on because a USB cable was on the workbench, made contact to a board, and this defective desoldering iron was at mains potential.
You have to stop using those cheap Radio Shack soldering tools.
