Intro: How to Design & PCB Etching- Part 2

In my previous tutorial I showed you how to make PCB design using easy EDA. And today I will show you how to transfer that design on to the copper clad & etch it.

So let’s get started.

Step 1: Watch the Video !

If you get bored reading all stuff here is the video !

Step 2: What We Need ?

So let’s see what we need :-

1. Once you have your design you can take print out of it on a normal paper. Don’t use premium glossy paper it gives same result as the normal paper. In this way you can save a few bugs.

2. Next we need is a copper clad.

3. FeCl3, you can get that in powder form or liquid.

4. A sponge with scrubbing pad.

5. A cloth iron.

6. Spatula

Step 3: Preparation & Clean Up !

Cut your print out in an appropriate size & measure the dimensions, then cut the copper clad slightly bigger than your design with the help of a saw. Now you can use a filler to round the edges.

Next

Use the scrubber and scrub the board, many people say to use a sand paper but I don’t recommend it, as the copper layer is very thin on these boards. Next, use the soap and clean the board so that it won’t have any oil marks, which will help the design to stick properly.

Step 4: Transfer !

Once the board is dried place the design over it & turn on your iron on maximum temperature & keep moving iron over it for at least 5 minutes which will transfer the design over the board.

After this, throw your PCB into water and after 5 minutes slowly start peeling of the paper. Do it carefully and try not to damage the design. Make sure your design is proper and, if not, use a marker to fix any broken traces.

Step 5: Etching !

Now it’s time to prepare the solution. Take a glass plate & pour some water in it and I repeat use glass plate as metal one may react and plastic can melt & also don’t forget to wear the gloves.

Now pour the powder into water, here the amount of FeCl3 will vary according to size of your PCB & give it a stir. And put the PCB in it.

Now you will have to wait for 15-20 minutes or even more but if you want to speed up the process you can keep stirring it. And when you see no copper around the traces that’s the time when you are done.

Now rinse the PCB with some fresh water & then you can use scrubber to remove the ink.

And your PCB is ready.

Step 6: Drill and Solder !

Now use a dermal & make holes where necessary, solder your components & this project is complete.

Step 7: Thank You !
