make Printed Circuit Boards, easiest method

April 5, 2023

Make PCB at home very quick and professional. this circuit is a powerful power bank boost converter with the low price MC34063 dc-dc converter ic.
tools and materials needed:
1. computer or smartphone with the PDF file of the PCB design in actual size
2. laser printer
3. light photo glossy paper
4. raw boards (copper clad laminate FR4/fiberglass)
5. a blade to cut the boards
6. iron
7. homemade ferric chloride (FeCl3) was used as etching solution
8. water!
9. time..
I’m using an air core inductor instead of ferrite or iron powder to be able to achieve high peak currents without hitting the core saturation and core losses.
