Homebrew PCBs

That's rubbish. Make a search on how acetone peroxide actually is produced and the needed care and equipment. Besides, it would stay in solution and decompose at the temperatures used for etching.

That people actually believe these old wives tales is the cause of the hassle at airports and restrictions on access to useful but largely innocuous materials.

      Hi All,

I don't know if this has been covered before but in using the  chemicals

Muriatic Acid (hydrochloric acid) and Hydrogen Peroxide to etch 

circuit boards with - if someone accidentally spilled some  acetone

into the etchant mix they could inadvertently produce a high  explosive

called Acetone Peroxide. Some people use Acetone to clean the copper

boards with prior to etching so it is possible the chemicals could be

accidentally mixed together. I believe the reaction produces white 

crystals that are the highly unstable explosive Acetone Peroxide. 

 

There is no such danger when using ferric chloride. Just a reminder  to

be careful when using these chemicals.
