PCB making

[accentsa]

another alternative to printing a transparency would be to purchase a film positive. Some layouts require higher quality then a desktop printer can offer. Accent Publishing

in San Antonio does a great job. 210-654-9555 dan@accentsa.com

With what pickle/fawn this PCB tile??

[tihikiller]

this was just copper block?? pls answert me

[FzFansa]

people please read what he has put in the description... he sais ff X8 if you dont know what it is ill tell you.... it is fast forwarded 8 times the normal speed :D

[JackUzi13]

@FzFansa

Yes, it is :D

[GTechno13]

I thought sodium persulfate was slower than ferric chloride.  Looks like a time lapse to me.

[mahawan79]

boss what acid u use

[JackUzi13]

@cumesoftware

Think so

[JackUzi13]

@cumesoftware

Think so

[JackUzi13]

@cumesoftware

In this case: Na2S2O8

[goffy44]

ive use the works toliet bowl cleaner lol but works great

[JackUzi13]

Show me your method and PCB wise guy.

Traces are so wide because it is a stroboscope circuit, so the have to deliver a big load of power in a short period. Thin traces are good for low power logic etc.

For uC applications I usually do traces around 20mils.

[elektronickz]

even for a stroboscope those traces look pretty big mate, 20 mils sounds cool btw :) and as for my case, i prefer ferric chloride and trust me, i had used the method you were using and is pretty messy.

[elektronickz]

what you're using is hcl + h2o2

Be careful with the above method:

1. It is highly exothermic.

2. The output is chlorine gas which is a poisonous gas, and can choke you to death if you keep inhaling it throughout your life.

3. This process is even more time consuming and messy compared to etching with the old faithful Ferric Chloride.

4. If you don't take care of yourself while using HCL, it will burn you to death! It is a HIGHLY TOXIC and HIGHLY CORROSIVE TO HUMAN TISSUE.

@elektronickz

It was in my eye a year ago and till now I'm fine.

ferric chloride is messy, the one I'm using is not.

[gnatho]

how long did it actually take ?

[JackUzi13]

viedeo runing time: 50s * 8(FastForward Speed) = 400s = 6min 40sec of process recorded.

time elapsed berore recording (PCB in solution, but no noticeable changes) about 10min.

So: ~17 minutes

[libed91]

i make a pcb in 15 seconds :) because i make a stronger mixture of acid and water.

[JackUzi13]

Acid? What kind of acid?!

[libed91]

i don't know how is it named in english, but it is being used in our country by those who don't have a CNC.

[libed91]

muratic acid + hydrogen peroxide

[edwardholmes91]

We use Ferric Chloride but this is very messes and can stain badly if you get it on your clothes. Another clear etchant solution is available but I don't know the name of it. As for time it takes us about 5 minutes to 15 minutes depending on size of PCB, temperature of solution, use of bubbler or not and how saturated (old) the solution is. We use a bubble etch tank however I do believe a spray wash tank gives much faster results.

[libed91]

HAHA

I don't even care about those acids anymore, because right now i am building a CNC which will hopefully be finished until next month.

:P

[TrySync]

Nice videos

Thank u

[asturboy77]

what kind of chemikal product made that?

[JackUzi13]

In this case: Na2S2O8

or You can use Iron(III) chloride.

[jaa93997]

Is there a commercial brand for Na2S2O8

[JackUzi13]

In Poland: B327

[First2ner]

HAHAHA nice, I can watch this happening... too damn long :D
