Thank you so much Zach for all the content. I have been watching your content for past 6months and I just got a good job opportunity at Capgemini as High speed HW designer. Your content enriched my knowledged and improved my skills.🙏
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.
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.
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
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.
