Hi Phill:
    Do a search on the technet for dendrite posts.  This topic has been discussed recently.  If you do not want to spend on an ionograph, call this fellow. Umut Tosun [[log in to unmask]].  The company he works for has a product that turns the flux blue when it get in contact with it.
Here is a site to read.more about dendrites.  http://www.divsys.com/ServicesProducts/PCB/Cleanliness/Cleanliness.asp.
        Regards and good luck.
        Ramon

> Are dendrites electrically conductive?
>
> Can they be formed when a circuit board is submerged in dielectric oil (Shell Diala AX)?
>
> How do I prevent them?
>
> Can I remove them or is the board now scrap?

> And to help educate folks here, where is there a good mini thesis on them?
