Comment on Is This The Last PCB You’ll Ever Buy?
JustEnoughDucks@feddit.nl 5 days agoVias are necessary for literally every part of electronics design beyond the basic I take a premade module and hook it up to these other 2 premade modules (which all have many vias on them), not just small packages.
Most PCBs nowadays are ≥4 layers. You need vias to use the center layers. Vias are necessary for ground return paths, stitching, shielding, RF plane coupling, signal integrity, and much much more. Single layer designing simply does not work if one is actually designing electronics and not just quick and dirty throwing 2 data busses together for a proof of concept.
BGAs don’t need vias, they are so small (0.5mm pitch and smaller) they usually need microvias (0.15mm/0.3mm ID/AR or smaller, which brings PCB prices from 15€ to 300€ for a set). Then the vias generally have to be filled at least and capped, optimally to not suck the solder through the vias from the balls. That is a whole other ballgame.

I etch and design my own boards.

Cool, what does that have to do anything? Are we just swapping facts about ourselves?
I am a professional electronics engineer with experience in high speed data signal integrity analysis, years of circuit and pcb design experience in medical devices, industrial, and consumer electronics, and designing and debugging for EMC.

It had to do with your tone and rudeness. Plus you are incorrect in some I’d your statements, but that is not something I care to address within a place that is about community and being a digital neighbor. The angst reply to a genuine comment is toxic 90s internet that should have died long ago.
