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. :)

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?

Simple PCB etching? Answered

To print out a pcb circuit you need magazine paper, a transparency or photo paper. Well I was just wondering if I can just take magazine paper out of a actual magazine if its a blank page and print right on to that and then iron that on to my pcb?

I want to Etch clear through Brass on a table-top Answered

I want to make some fake gears and such to decorate steam punk and sci-fi stuff.  I'd like to take brass or copper and etch clear through, and have a "clean" edge.  Sharp I don't really want. I need to transfer an image from a computer-drawn source.  Heat transfer with toner I know, etching, well, not so much.    I'd also like to do this on my kitchen table.

"Massively Reduce Laser Etching Time"

The guys over at Redtorope.com have been addressing a way to reduce the cost of laser etched/cut projects when having a job done or reduce the wear and tear on one you or your company owns. It's not really a hack or a hardware fix, just an exercise in thinking within the operating parameters of the machine. Really well done and explained in such a way that others will be able to apply to their own projects. Well done fellas!  http://www.redtorope.com/2010/11/massively-reduce-laser-etching-time/

Should I post? (Well, not exactly)

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.

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!

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

Leah's etched laptop continues to be copied

I thought Leah's ad-supported laser-etched laptop was brilliant. When we were first talking about it, it was obvious that if she could pull it off, there would be a bunch of copy-cats trying to do the same thing. Obviously Squid Labs and Instructables are listed as sponsors, so I get a number of emails asking for further laser-sponsorship of laptops, and they always make me smile. Here's the latest, hope you enjoy the irony as much as I do: Dear Instructables-TeamIn the very near future I'll need a laptop for school. To finance that, I am planing to put Ad's onto the top of it.I am visiting a college of higher informatics. The school has more than 1000 students, teachers and other workers & visitors every day.My suggestion is a cheap way of advertising. The ad's would be laser etched into the top of the Laptop (made out of Aluminum). The Laptop has a size of about 40 by 27 cm (= about 14 by 10 inches).If you are looking at prices of an often-visited website for example, you'll get prices between 700 and 1000$'s PER MONTH for a little ad.For 1000$ you could cover the biggest part of the whole notebook, but you wont have to pay monthly. You only pay once, and the laptop will be used for 3 or 4 years. Also the laptop will be presented in the internet in several forums. I will post into a few forums myself, and make a little video about the laptop, and the company's that put ad's on it, and also other people will show around pictures of the project, because it's very unusual to do something like this.Of course you dont have to buy an ad for 1000$. Size, type of ad and therefor price are free of choice.I am looking forward to an answer !If interested, I could also send you some pictures how laser-etched things look like on a laptop and we could talk about data or prices if you are interested..

ASUS EeePC review and Laser Etching

Asus, a sponsor of Instructables, has put together WePC where they are asking for input on their next generation laptops. As part of their sponsorship, they've asked my opinion on various aspects of laptops. Most recently ASUS EeePC review and Laser Etching.As part of this campaign, Asus was kind enough to lend me an EeePC. I gave it to an intern at Instructables, Matthew Dalton, who was really excited to try it out for note taking in class, and general portable computer usage -- his review follows below. Since I've been writing about how important it is to customize your laptop, I also asked Matthew to give the EeePC a laser tatoo, and you can see the results were beautiful! Matthew' review continues here.Finally, I'd like to know what you have thought about this Asus campaign. If you would be kind enough to take this survey, I would really appreciate it. Comments here are also good. Thanks!https://www.instructables.com/id/Instructable_Robot_etched_onto_ASUS_EeePC/

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!

What laser do I need for laser etching?

The questions says it all; I am planning to build a custom 2-axis computer controller etching machine out of a modified ink-jet printer. The motorisation and computation part it not a problem yet, however I have no clue where to start from about looking for a laser. I am looking foward engraving/etching wood, metal, plastic and some other soft materials. I do not plan to CUT these however. I do not know what kind of laser I am exactly looking for, nor it's power or anything else I should be aware of, including where to order it from. Even, will a DVD burner diode do the job? If you have any past experience with laser etching, or laser technology, please contribute as I would be very grateful. Thank you.

Can someone give my PCB design a once over before i etch???

Hi everyone, hoping someone can help me here. I have designed a pcb in expressPCB and was wondering if someone with a bit more knowledge and experience could give it a once over for me.  I just want to be sure there are no errors before i go away and etch this. The design is based on a 30 channel ambilight tutorial that is here on instructables.  It uses two TLC5940 chips that are connected to an arduino.  I have left the arduino pins on the design unlabelled as they connect slightly different on each arduino (mine is a mega 1280). Here is the design.  Please be gentle, i am just starting out with pcb design and have no breadboard at the moment. :)

Get into PCB creation? Answered

Well I just realized over the past few weeks that I really need to start getting onto the PCB bandwagon and start manufacturing my own stuff...  So... I need materials and instructions on how to make my own PCBs... I have copper boards already (sourcing them is not a problem...), and i am pretty good at designing boards in EAGLE (I find it fun), but I need a method of etching them.... I have tried many toner methods and they never work how I like, I always get some pretty big mistakes and etching them sucks...  I have heard of photo resist methods, and it sounds wonderful because it has a pretty good accuracy and can go down to some pretty fine wiring... My only problem is that you have to get presensitized boards (Expensive!), as well as other chemicals... As for etching, I think I am fine, I have used a vinegar/salt/something combo and it works pretty well, just takes a while to etch.. I have some muratic acid but that stuff is nasty so I have never really tried that.. Anybody have any non-toner PCB creation process that is pretty inexpensive? (I am in high school and have a limited budget already...)

I've been using 3% hydrogen peroxide from a pharmacist and 30% HCl From Bunnings. All the stuff was fresh and in dark plastic bottles. The container i put it into is plastic. It still etches but it's nearly impossible to see if the copper is etched away without pulling it out. Can anyone tell me what's in the mixture that's making it red and how i can correct it. Thanks

How can I get my power supply to stop blowing fuses?

I built a power supply using a 25.2 volt 2 amp transformer to use for etching projects.  It worked on my test plate but then started blowing the 1 amp fuses I was using with it.  I switched to 2 amp fuses and it works but my transformer is getting too hot.  I have experimented with different amounts of solvent and different size plates, which definitely makes a difference, though my 1 amp fuses are at most lasting about 10 seconds.  I have read about building a control box with a halogen light and a variable resistor to control the amperage, but would it allow me to take some of the load off of the transformer?  And if it would work, how would I connect it to my power supply?

How to remove the copper layer/film from a PCB ???

Hi ... do you know, how to remove the copper layer from a PCB - by not using any ETCHING METHOD. Just to separate the cooper from plastic/f.glass ??? Do you think, that HEAT would do the trick ??? Like when you hold soldering tip to long on a pcb, it can happen that the cooper film become loose from the PCB. Thank you in advance. Zholy P.S. : The reason, why I asked = I was thinking of creating/extending a "ribbon cable" : 1. remove the copper film 2. stick it to the foil, that you can laminate 3. put the "ribbon cable pattern" on the film and ETCH it. 4. laminate it ... and cut the just the top of the laminate foil at the ends, so you have clear cooper for the contacts, but the bottom laminate film as a support.
