Homebrew PCBs

I would be VERY careful about using MEK heaps - its an effective solvent 
for sure, but it also a recognised carcinogenic here in Australia, and 
therefore in the workplace occupational health guys go nuts over 
quantities used by individual workers and amospheric systems.  But on 
the other hand, acetone and IPA are also highly flammable!!!

  Whichever you use use in a well ventilated area and be careful with 
ignition sources!!!
