Etching PCB boards

I know that copper is a better conductor than tin or aluminum. But one of my friends a few days ago told me that instead of etching his layout on copper, he used the bottom of an altoids tin. he said all he did was sand the bottom until there was no paint of the altoids can and then he etched his layout. (Chemical bath, toner, etc.) So my question is, Does anyone know how to etch custom layouts (toner layouts) on tin or aluminum? **I figure this could save people some money and time on some projects. :)

Salt and water etching

I made an instructables about salt and water etching https://www.instructables.com/id/SALT-AND-WATER-E...as I learned it in a jewelry class, so I never tough about been unsafe. I posted it as I tough it was a nice one to share, but I'm having some comment on how it should not be safe using stainless steel in this project. As I don't have absolute knowledge about this before, and I just report what I learned, I was wondering if that was correct or not. (I know sometimes people comment very random stuff). Anybody know something about this topic?

PCB etching question?

I wanted to start making PCBs. However, I read that because the chemicals dissolve the copper, you can't dump it down the sink or throw it away because it is "hazardous" and should be taken to hazardous waste disposal. I'm still in high school and can't really do that and/or my parents would think I'm doing something dangerous. Is there any other way to etch PCBs besides using chemicals, like a knife or something?

Sanding Laser Etchings and Saltwater Etching Through Anodization ?s

I own an iPod Shuffle, 2nd generation, silver. It is very plain, and I've recently been reading up on saltwater etching. I want to remove the standard Apple logo from the back and etch my own text (it will either be "iMake" or "iBles", I can't decide). I've come upon two roadblocks, so far, those being: can I sand laser etchings (the Apple Logo) off, and can I etch through the player's anodization, or would I need to sand that off? I don't really care if it doesn't turn out perfect, or looks like a total mess. It's not like I paid for the thing. Thanks for any help!

So, this really isn't whether or not I should post an iBle, but rather how many of you are interested in it. I'm using the saltwater etch tutorials here and am going to etch my iPod shuffle (2nd generation). The etch will say "iMake" and if all goes right, I should begin to etch sometime today or tomorrow. So, I'll try to take quality pictures and all, and if anyone happens to have any tips for me, they would be appreciated! ;-) Thanks!

Should I use .032" or .062" copper clad to make my own PCBs?

In all of the tutorials for making your own PCBs, I've never seen the thickness of the copper discussed. Does one work better than the other for home etchings? I plan to use muriatic acid. Side note: does RadioShack still carry copper clad in stores? It's not on the website anymore, and I don't go to RS on a regular basis to check.

I need your opinion....

Ok, so I am within about a day of etching my iPod via saltwater. I am going to attempt to just let the clip (backside) of it rest in the water, using contact paper to guard against water damage to my circuit board. That is one option. The other is to remove the circuit from my iPod, leaving just the case. I've never done this, but have a guide. Do you think it'd be worth it to dismantle the player? Any, and I do mean any, suggestions are appreciated! Thanks!

Teach me a bit about lasers

Im in the process of piecing together parts for a 2 axis CNC and I would like to use it for laser cutting/etching. Since I'm new to building CNCs and I also dont have a ton of extra money I plan to build one using a DVD-r laser (200mW?) and just do some tests to get the basics down and play around with it. I would love to be able to cut 1/4'' acrylic as I have some laying around and I love some of the projects possible with it. What is the cheapest laser that is capable of cutting clear 1/4" acrylic? I have used a 40W co2 laser and it flew through the acrylic like it was nothing. Is there something for <$200 that would cut it?  And is it something that you can just use a lower power and go super slow or do you need the power? I did some light searching and didnt really find what I was looking for but if someone has a link to some helpful info I would appreciate any help I can get. Otherwise ill just spend my days cutting and etching paper!

Custom Etched Halloween Tombstone

I created this custom etched Halloween tombstone using builder's foam, latex paint and spray paint. The method of creation is to use a water based paint to create a resist that will protect the foam from dissolving when painted with the spray paint. This technique works really well to create the weathered stone look that older limestone monuments take on after a couple hundred years. For this project I was trying to create a broken then repaired tombstone that was partially covered in moss. Project Process - First sketch the design layout using a marker. Then paint the areas that you want to remain un-etched. Next, spray the entire face tombstone with a heavy, even coat of spray paint. It will take a few minutes... but the face will be etched as much as 1/2" deep depending on how heavy a coat of spray paint. After the etching paint has dried, paint the entire tombstone with latex primer and then add any desired painted effects. For this project, I used a grey granite spray paint and then added sand that was painted a moss green color (adhering it with spray adhesive). Total active work time was approximately 2 1/2 hours. A full Instructable of this project to follow soon...

Use a 3d printer for etching PCBs?

Here's an idea - would it be possible to use a 3D printer to lay out the etch resist on a PCB?  It would likely only need to print a single layer.  Of course you'd need to use a material that would resist the ferric chloride but could also be removed without leaving a residue. Thoughts???

Can I etch a PCB in the winter...? Answered

I want to etch a PCB, but it is rather cold where I live. I had settled on the HCl/Peroxide mix, but I could use something else if need be. I wouldn't be worried about it, except I get the impression it's a good idea to carry out the reaction outside, where it is cold right now. If working outside in the cold is a no-go, is there any etchant that is "safe" (I understand that safety is relative, I mean along the lines not immediately gassing me) to use indoors with ventilation? If so, how much ventilation is needed? Are we talking an open window, or an industrial fume extractor? Also, I wasn't sure which category and channel would be the best, so if a mod or somebody sees this and has a better classification, go ahead and change it. Sorry for making this such a long question; I'd just like to be able to use my circuit board before I die ;). Thanks, dedgerton

PCB etching left over paper

Hey everyone! I'm in the process of etching my first PCB. I have a few questions. I'm using the toner transfer method, with hydrochloric acid and a little hydrogen peroxide as an etchant. Anyway, I transferred the toner to the board, but I believe the glossy paper I used may have been a little too thick. The toner transferred correctly, but i can manage to get all of the paper off. I've tried a tooth brush and a soft towel. My question is, if I just go forth and etch the board will the paper dissolve with the copper on the board and give me a clean result anyway? Will the copper covered by the paper not be removed? are there any cons to this? (such as not being able to reuse my etchant) Thank you all, your help is appreciated Ken
