Is this a new method?
CHAMPIGNON:
"Good morning. I made the following formula to make printed circuit boards, and I want to know if I am the first person in the world to use this method?"

thanks

It’s not new at all. PCB = printed circuit board, and the printing this refers to was screen printing, originally.
There are numerous reports of people making PCBs this way, but it isn’t done much anymore because other methods are better.
CHAMPIGNON:
thanks
I tried all the methods I found on the internet.
--The thermal transfer method from paper to the board gives inconsistent results that depend on the type of board, the level of cleaning, the time, and the type of paper used. If I make a mistake once, the board cannot be reused.
--As for the method of transferring the image from paper using acetone, its success rate is not 100% and depends on the quality of cleaning and the type of paper used.
--As for the blue film method, it also has several drawbacks, including the appearance of air gaps.
--As for the method of using a board coated with a UV-sensitive layer, I had bad experiences with it. It is expensive, and there is a high chance of purchasing an expired board.
As for the method of modifying printers for direct printing on the board, I haven’t tried it because there is a high chance of damaging the printer. The board is not perfectly flat, which could cause some parts of the printer to get scratched.

Please, where did you find a method like mine that uses the phenomenon of electrification to transfer ink from paper to the board?
It’s worth mentioning that:
-In the printed board shown in the video, the width of the tracks is 0.5 mm.
-I didn’t clean the board.
-Using the same method, I can add a layer to protect the copper from corrosion.
-My method suits my financial situation, as my monthly salary does not exceed $250 USD.

Sorry, stupid me has no idea what the video is actually supposed to show.
You transfer toner (?) from a film to a PCB with the help of a bank card.
How does the image get onto the film?
What about some explanation aside baby sounds in the background?
Please cut the out of focus scenes, they hurt my eyes and brain.
The resolution the method seems to deliver isn‘t impressive either.
Time ago I made a simple PCB with a QFN footprint with the ironing toner transfer method, but have given up on this home chemistry stuff now.

I think, I understand your situation. I live in Poland. Till 1989 we were communistic country. I remember times when working as academic teacher my salary was $13 per month (I count not official exchange rate that you were allowed to buy 130$ once per 3 years and only provided they gave you your passport this time, but exchange rate that I was able to use daily).
As a child (70s), I used to draw tracks on PCBs with a ballpoint pen lead with the ball removed, using a paint I had found in a magazine that people used for this purpose.
After etching I painted the boards with rosin dissolved in spirit, and this is sufficient protection against corrosion for amateur use and makes soldering easier.
In my opinion the most important is that your method will not let you to have plated holes. Professionally manufactured PCBs are incomparably better than any homemade ones.
I have never ordered from JLCPCB but according to what I see at net prices are in a range of few $. I don't know about shipping, but I imagine that if you're not in a hurry it can be cheap too.
According to my experience if the salaries in the country are small than also local manufacturers charge not a lot for their work. I simply suppose you should be able to find local (not city, but country) manufacturer with enough PCB quality and acceptable price. You need not to order lot of PCBs. You can check your conceptions at prototype boards. I have one (old) prototype PCB at which I assembled and disassembled many, many circuits during last 40+ years.
