Hi,
I'm using small PCB boards which are to be connected using eyelet crimped terminals and brass bolts/nuts. The bolts/nuts are M3. I'd like to prevent the nut from unscrewing because the system will be mounted on an electric bike (lots of vibration).
I'm thinking about using a threadlocking compound such as Loctite 290 or Loctite 270. However I guess these fluids will increase the resistance because zhey aren't supposef to conduct. Do you see any objection to doing that?
Is it better to use Loctite 3800/3888 which is a conductive epoxy? I cannot find M3 brass nylock nuts since most are made of steel or stainless steel with some coating in zinc (this may trigger galvanic corrosion with brass) so nylock is not an option nor are washers etc which would damage the pcb.
What would you use on eyelet terminal to make a good contact with pcb yet prevent any nut from getting loose?
Thanks
