Homebrew PCBs

Hi,

 

You are safe, it takes a little more than just Muriatic Acid and hydrogen
peroxide. It's also a bit more complex than simply mixing it all together.

Subject: [Homebrew_PCBs] Explosive Byproduct: what are the risks with
muriatic acid?

 

  

Hello, fellow PCB makers,

I'm new to the etching community, and most of my learning has come
either from here or other places online.

I've made 3 successful boards so far using the Toner Transfer method and
Muriatic Acid with hydrogen peroxide, but I'm worried about a critical
step:

After removing the etched board from the etching solution, I dried it
with a paper towel and then cleaned it with acetone. Am I at risk of
creating small particles of the friction-based explosive Acetone
Peroxide because I didn't first rinse the etched board with water?

Without knowing about this accidental byproduct beforehand, I've already
soldered components onto the board and added a layer of epoxy to the
bottom as a sealant.
Because this board is going to have to take a lot of vibrations (it's a
quadcopter controller board), should I trash it to e-waste and start
over?

Lastly, has anyone had any bad experiences in accidentally making
acetone peroxide on their PCBs using HCL, H2O2, and Acetone?

Thanks everyone!

Sincerely,

Poofjunior
