Etch PC Boards clean and easy

[bdevlin]

I just started doing this.  I get a plastic container that I only use for secondary containment.  I put the PCB and the least amont of etchant needed in a small zip top baggie.  I shake the bag as much as I want for agitation without the worrie of spillage and I can grab the PCB from the outside of the bag to get a good look at the progress.  The best thing about this is that you don't waste etchant.

Paul Marrossy posted a thread about doing this a while back.
It is a great idea for a few reasons.
Neat.

if the bag is the secondary container, what do your put in the first container?

[Tony Forestiere]

Hot water. It absolutely speeds the etching process.

GENIOUS!!!!

The bag is the primary container.  It holds the etchant.  A plastic tray or container would be the 2nd container.  What a great idea to put hot water in it.

I just microwave the ferric chloride until I see that smoke, then I know it's hot .

I use persulphate, so I don't know whether that would generate some hydrochloric acid fumes... not poisonous, but not very good for your microwave, if it does!
