Pls one video on single layer pcb design through hole components without schematic dia.

@Zachariah-Peterson 7 ай бұрын

Are you asking how to create a design without using schematics? That is not the proper way to create circuit boards, you have to create schematics as this is what defines all the net connections in the PCB layout.

So is it accurate to say that in theory, all traces should be as far away from each other as possible?

@Zachariah-Peterson Жыл бұрын

Maybe a better way to say it is, in theory, trace spacing to ground distance ratio should be as large as possible as this is the best way to reduce crosstalk and mutual capacitance when dealing with digital signals.

Great video. Learned a few things and look forward to how you apply it in Altium along with some real world examples 😁🏴󠁧󠁢󠁥󠁮󠁧󠁿

Pcb manufacturers offer differnt stackup layer thicknesses for multilayer boards. Eg in some prepeg between top layer and next layer is 3.8 mils and 8 mils ... Plz describe such qs in a future lecture ... appreciate

@Zachariah-Peterson Жыл бұрын

We have not looked at this specifically but I have shown through calculation some ways that the layer thickness (distance to ground) affects parasitic capacitance between two elements. I do this in the linked blog titled "Parasitic Extraction with an Electromagnetic Solver in PCB Routing" and I've done it more recently in a video on crosstalk.
