Introduction: PCB Etching

PCB etching is not a technical thing but an art, modern electronics
technology is incomplete without PCB. By using PCB any complex circuit can be made easily.

In this tutorial I am going to show you how to etch a PCB

Step 1:

Step 2: Hardware


1. Copper Clad PCB

2. Magazine Paper

3. Laser Printer

4. FeCl3

5. Water

6. Electric Iron

8. Metal Scrubber

9. Sunmica Cutter

10. Scale

Step 3: Print the PCB on Magazine Paper

magazine paper can be collected from old magazine, so it is very cheap. in this instructables i printed the PCB on magazine paper using laser printer. After printing cut the paper of the print size, so it can be transferred to copper clad PCB.

Step 4: Cut the PCB

Cut the PCB of the size of print area this can be done using sunmica cutter. after cutting clean the PCB using metal dish scrubber and dish wash.

Step 5: Toner Transfer

In this part I am going to transfer toner to copper clad PCB. In this part just put the paper on PCB and round the Iron on paper for one minute. In this way toner is transferred to copper clad PCB, and paper is strongly pasted to PCB.

Step 6: Remove the Paper

Now place the PCB in water for 10 to 20 minutes and remove the paper slowly using thumb and fingers. In this step paper is removed and toner can be easily seen on copper clad PCB.

Step 7: Dissolving the Copper

Now place this PCB into mixture of water and FeCl3 (Ferric Cloride) for 10 to 20 minutes, In this process copper is completely removed and dissolved into FeCl3, Now Take out the PCB and clean with water, if copper is not removed place the PCB into FeCl3 for some more time.

Caution: FERRIC CLORIDE IS HARMFUM FOR EYES AND SKIN

Step 8: Drill Some Holes

Drill some holes into PCB using drill, Now your PCB is done.

I do nearly the exact same procedures but I use a product called P N P Blue paper made specifically for doing LASER printing for circuit boards. It works very well and quicker then the magazine method. And I mix up a gallon of powdered Ferric Chloride and water and then use portions as needed.

And just for a safety concern, ALWAYS put the Ferric Chloride powder (an acid) into the water and not the other way around. Because as you are pouring in water, the mixture is full strength until all the water is added. Not a good thing. And Ferric Chloride and water IS a an exothermic reaction and does release a lot of heat and gets pretty hot. I would use eye protection and even face protection at a minimum.

Good project otherwise.
