Making PCB at Home (Step by Step)

اسلام علیکم

Here is an other one article related to PCB (Printed Circuit board) designing. PCB designing is very important for Circuit designing engineers. PCB Making at home is the need of Students or hobbyist persons because they are making some samples of circuit. But some Professionals and businessman engineers order the for PCB making companies like JLC PCB, PCB cart etc. they received bulk order as well for some mini 5 samples also but 5 sample is costly more then bulk quantity. 

But here is my MSc course Project at ISRA Uniersity Islamabad {Control Home appliances using Mobile (cell phone)} this project was DTMF based (here is not required to discus more about Project but PCB).

Description:

Here PCB method is iron based by transforming toner on transparent sheet then etching by ferric chloride. 

I am explaining method step by step.

1. Take a Copper sheet of specific area and rub that by zero size sand paper.

2. Take a mirror Print of PCB layout on Transparent sheet

3. First to little heat up to Copper sheet which rubbed by sand paper then adjust PCB layout Print on Copper sheet, then set a double paper on that and heat up by iron approximately 10 minuets.

4. Peel out the transparent sheet after above time

5. Make a ferric chloride 2:1 solution in a tub then do etching

6. You will see the results like that

7. Do manual drilling by small drilling macine

8. Insert Components and do Soldering

9. Circuit Board is ready 

the above Layout was not Professional because I was not PCB expert but now I am designing professional PCBs also, if any one want my services the connect me by email.
