You need chinese tap water, it has more ferric chloride:

Might be simpler and better to Blu-Tack® neodymium magnets to the back of the board. That will attract the little ferrus buggers to concentrate around the board.

Makes you wonder why copper water pipes last so long. Especially the hot-water ones.

I said it before, I say it again: most of the world have no idea about this April tradition that is carried out in some English speaking countries.

This one I actually disliked. This was a huge and malicious waste of my time.

Holy smokes, I tried it and ended up with gold plated traces! Next project is to recover the gold using the reverse process.

Still the 31st here but excellent "Poisson d'avril"

Damn, doesn't work in southern Germany, bloody mountain-spring-water ...

That mostly works with water available around old copper mines or other non-ferrous metals, like they are plenty in Oz, in Southern Germany one needs to add a tea-spoon or two of Bärlauchsalz depending on PCB surface and use 12V AC.

I was... WTF ?

...then a I looked at the calendar !

It was when you brought up the magnet that I realized you're a day ahead of me.

i am going to start a PCB etching bushiness in australia. this reduces cost of manufacture significantly!

That's a big nope ! You'll have to waste a lot of water to collect a decent amount of Ferric Chloride !

GigaJoe · « **Reply #37 on:** April 01, 2019, 04:32:22 am »

no waste water at all: bottled water "EE-IONS" brand. and ship it to China.

o! post# 222 ...

WTF, I posted in this thread last night (though I didn't have time to build it to scale, OR paint it), and now it's deleted?? Huh?

artag · « **Reply #39 on:** April 01, 2019, 09:22:31 am »

Shouldn't you dilute that concentrated water before you pour it down the drain ?

bitwelder · « **Reply #40 on:** April 01, 2019, 09:31:21 am »

Hmm... I'll steal the idea and go prepare an Indiegogo campaign for a special magnet that makes PCB etching at home so much quicker.

BRB!

Psi · « **Reply #41 on:** April 01, 2019, 09:37:24 am »

Back to reality though. I do wonder if you actually left a tap dripping on a PCB for an entire year, would it dissolve any copper?
I'm not sure, but if it did i wouldn't be all that surprised.
There's bound to be something in tap water that will slowly eat copper over a long enough time frame

Here is another tit- bit of information on Iron dissolved in water, the forming of "bog iron",https://en.wikipedia.org/wiki/Bog_iron.

And as usually wikipedia is full of errors as if it was made outoff 1 April's all year around.

The Apollo 13 astronauts used this trick to repair their damaged navigation computer which allowed them to safely land in a New Jersey Sears & Roebuck parking lot.

Actually, it's damn international date line.

I have a limiited supply of special PCB etchant magnets which I will part with for $10 each. I also have for sale a supply of dehydrated toxin-rich Los Angeles tap water @ $5 per gallon.

you sell it as spring water after you get the chloride out
