Ledtester,

As promised, follows the sequence of images, demonstrating how I assembled the PCB, by hand.

1 - I developed the entire pcb layout in EasyEDA;
2 - generated the gerb file;
3 - from the gerb file, print the complete layout and the holes (image 1);
4 - With a needle I pierced the paper at the perforation points (image 2);
5 - With all the holes ready, I cut the paper so that I could properly fix it to the plate (image 3);
6 - It is necessary to invert the drilling design when fixing on the plate (image 4);
7 - fixing the paper to the plate (image 5);
8 - With a mechanical pencil I mark the position of the holes on the plate (image 6). Observe the graffiti, marking the perforation on the plate (image 7);
9- With the pcb layout inverted, my occupational therapy of joining the dots begins. I use the 1mm and 2mm pens. Retro Projector Pen. (figure 8).
