PCB etchant

[toked323]

anyone know of any good homeade or place for pcb etchant, besides the muriatic acid and hydrogen chloride? they are too dangerous for me

Radio Shack sells ferric chloride in 16oz. bottles in-store for $4.50.. If you warm it up and agitate it while etching, it works pretty good.

My local Radio Shack still carries it and it's still listed on their website as "available in store"..

Almost any kind of paper will work to a degree but glossy ink-jet paper seems to work the best..  I always used the JetPrint brand from Staples.

all friggin etchants are dangerous. I use sodium persulphate as an etchant and sodium hydroxide as a photocoat developer.

hey when you get the chance put muriatic acid in a bottle with foil and close it, it makes a loud bang

AKA "The Works" bomb

put "the works" (toilet lceaner) and tin foil in a bottle, be ready to make up an excuse for the noise

Dude!! I absolutly hate that stuff we got like 5 bottles of it on sale and when i tried it it started smoking in the  and it almost makes you pass from the fumes  lol.. i have to try that.. do you just put it in like a water bottle with foil inside the close the lid?

Man... its almost gone but i have another one that has a 16%Hydrogen Chloride (the same active ingrediant in the works) would that still work or is there something else that makes it do that.

...lazer... ;D ;D ;D

 

[toked323]

no for the bottle just muriatic acid, not peroxide, i never realized how dangerous that stuff was till i went to home depot and they said they cant keep it in the store.
i had to buy 2 gallons for 9.99$ i didnt need that much i needed like 1 liter but oh well

 

[amkdeath]

put tin foil in bottle. pour in the works. close lid. hide behind bush for like 5 mins. then BOOM

 

[toked323]

yea i did that and wow i was barely able to hearr

 

[wooooooolazer]

Awsome i guess that other type has it in there too, the first one i didnt put enough foil so it took about 30min to go.. after 10 min i gave up and left it out there then 20 minutes later i heard i big boom all the way in my house ;D.. the next one went off in like 5min but the bottle had a leak and didnt explode so it wasnt very loud .

Im gona try it with a 2 liter bottle later.. that should be biggg.

..lazer.. ;D ;D ;D
