Simple Home Made PCB Layout Using 'eagle Software'





Introduction: Simple Home Made PCB Layout Using 'eagle Software'

About: I am an electrical student living at chennai i love electronics very much.

(UPDATED ON : 09/07/2015) Surprise for viewers I have earned pro membership for that i got promo codes & offers from these websites (adafruit, lion brand yarns, lumi, pijuice, pisupply, brainybits).Anybody who want buy anything from those sites Click Here there i have posted all the promo code which i earned. And please vote me.

Hai guys Designing your PCB’s at home is been a hobby for many of us.

Today aim going to show how to design the PCB layout for your electronics project. I used eagle 7.3 software to develop layouts.

Step 1: Materiral Needed

List of material:

°•copper coated single layer PCB
°•photo glossy sheet
°•ferric chloride
°•iron box
°• A computer installed with eagle software

Needed tools:

•°Hand glove
•°drilling machine
•°soft nylon brush

Step 2: Using Eagle Software

The first thing before you getting start your schematic and layout for your project the software you need is EAGLE.

Downloadit via google So, first of all you’ll need a circuit diagram, decide what you want to make and create a circuit design on a hard paper and note down all the components that are required to create it.Once done with this, open your eagle application or any other circuit designer application which you are familiar.

I designed the circuit to convert 230 AC Volt to 5 volt DC.

Step 3: Routing

Now its time for routing the connection lines.
In EAGLE application goto File
->Switch to board view.And place your components on the board. Now click the auto-route function which is in bottom left corner. The application itself route the schematic connections

Step 4: Printed Layouts

photo glossy sheet is used for printing the designed layout in PCB.
Now place the copper side of the PCB to the printed side of photo glossy sheet.

Step 5: Ready to Print

After placing the PCB fold the photo glossy sheet tightly as shown above.

Step 6: Printed Layout on Pcb

After placing and folding the PCB in the correct position. Take the iron box and set it to max.Now with slight pressure iron them for 8-10 minutes.

After completing the ironing process wait for few minutes then slowly open the sheet you will get the layout in the PCB.

Step 7: Eathicng Process

This is the final process.

Now dissolve the ferric chloride in the water.And soak the printed PCB in the solution then shake the PCB for few minutes until copper in the board is dissolve in the solution.

Step 8: Double Layer Board

This board is printed in both the side with the same process.

    I really like this instructable, thanks!

    But try to save some etchant by using ground planes - at least for the small signal/low voltage area. It kinda hurts to see a rather simple circuit using such a fancy PCB

    I never got ground planes to work right in Eagle. I have not tried in a few versions though. It might be fixed now.

    It has been "fixed" for long - I've been using ground planes for ~15 years.

    I prefer (and use) mainly v4.16 (with non-windows controls unfortunately), as they lowered the contrast since v5.x), but I've made GPs in every version up to the current v7.3 - so there's absolutely nothing to fix (on the SW side) - let me know if you want a crash course - it's so easy.

    Thanks, but I do not etch boards lately. I just wire them up point to point. I still use Eagle to design my parts layout though. What contrast is lowered in Eagle? I use version 5.12.0 I do not think I know what non-windows controls are either?

    Sorry, didn't get a mail on your response and just discovered it by accident.

    A picture paints a thousand words, far more than I'd like to on this issue, but see for yourself :)

    The non-windows controls, I should have called Win-3 controls of course, like ALT-Backspace to delete (Ctrl-Z) and such, annoying if you have to cart your right hand from mouse to keyboard and back all the time, but I'm using a macro-pad to deal with all that.

    Funny thing (or rather not) is that Microsoft that has been preaching accessibility "forever", has gotten on the same train - win 8.1 is hopelessly low contrast, with no way to alter it (M$ wants to be in charge) and there's 0 logic in making eg. a scroll bar "handle" that is invisible until you hover over it, then it gets a slight contrast, but first when you have grabbed it, it become reasonably visible (when it's not needed anymore - Luckily there's an extension for Firefox named Darken, it can be set to maximize contrast - without reverting to M$'s p-ugly high contrast schemes - why do they think they can get away with crap, just because people have more use for contrast than the crappy wine gum they plaster it with *tsk*.

    Sorry to unleash one of my pet peeves on you :)

    I'll post a page in the near future, with full ground plane on the entire PCB. Check it out if you like :)


    Eagle can look like that here too if I am not zoomed in really close. I don't do Windows at all either. I need an OS that is easier to administer, so I run Linux.

    With 4.16 there's the same contrast ratio at any zoom levels - in-app contrast is not governed by the OS.

    And yes, Linux was good at a point in time, but I think it has become almost as bloated as Windows in later distros.

    How bloated Linux tends to be is completely up to the person installing it. Perhaps bloat is not such a bad thing? It isn't for me if everything works properly. My system is running 94 tasks right now, but everything works, so it is of no consequence to me. No, my issues with Windows go far beyond bloat.

    Why Eagle when you can use KiCAD? It is OpenSource, free, without limitations (PCB size, layers etc), completely working now (yes, in the past were issues), with community support, for Windows and Linux as well, offline (not cloud based - there are tools like the ones from Altium which are cloud based and your project is everybody project :( )

    I never want to make a board bigger than the free version of Eagle allows, or use more than one layer. I am not going to edit the source code of the program either, so open source is of no practical value to me either.

    I am happy to hear KICAD works today though. Because the last time I ran it the stuff crashed before I could finish a tutorial. Heck, I don't think it lasted 3 operations. Open sores code.

    Eagle is in widespread use and have a shallow learning angle. Before Eagle, I solely used OrCad and such, but started using Eagle, because that was accessible to all the people I helped/guided, on the web and IRL.

    Eagle has been in the field (functioning well) for a long time, so it has a large following and lots of communities (also as sub communities on numerous electronics fora), I doubt KiCAD is a serious match in that respect.

    And while cloud this and cloud that is fine for a hobby project, I'd hate to risk the integrity of my bread & butter - open source and such is fine in a hobby setting, but you can't eat if you don't make a buck or two ;)

    Might be good to mention that this process works with Laserjet printing but probably not with Inkjet printers. The toner used in Laserjet type printers is plastic dust which can be melted by the iron to transfer to PCB surface.

    You can also use any paper with a clay based surface because toner adheres to the clay and thus is easy to heat-transfer to PCB. With clay surfaced paper you can get thicker toner transfer by ironing your pattern onto the PCB and then soaking the paper and PCB in soapy water to soften and remove the paper.

    Ham radio experimenters have been using this toner-transfer method for as long as Laserjet printers have been available. There are many on-line articles that discuss "Toner Transfer PCB Making" methods.

    It is the paper used for printing photos. It is glossy(shiny) in appearance and is thicker than normal paper

    yes thats right

    hai sesha photo glossy sheet is avilable in all photostudios

    Glossy paper?
