How to make a pcb using marker pen. How to make a pcb prototype

Hello friends, In this video, altium designer, eagle, kicad, orcad, protel without using programs such as, you will see how to make a circuit diagram print circuit. Making PCB using print circuit board marker pen; although it is an amateur method, it is quite useful in some cases. We need to put the circuit we have drawn on the copper plate (pcb) into the acid bath using hydrogen peroxide (H2O2) and Hydrochloric acid (HCl). In this video you will see how hydrogen peroxide + Hydrochloric acid is used to melt copper. I'm thinking of making more comprehensive videos about printing circuit board production in the future. I will shoot videos about the construction of the printed circuit board (pcb) using an iron, lamination machine and dry film. You can write any questions about the video in the comments section.
