  • By all means share the designs of all of the 1 layer boards you claim! I said nothing about single sided boards, my claim was about vias.

    I would love to see “nearly every LCD monitor” that contains 0 vias! I would also love to see your SMPS designs that are 1 copper layer with no vias at all!

    Having all of the components on a single board side is something completely different, you can have a 16 layer board with 10k vias with components only one one side.

    Please, share all of these aerospace designs that use one single copper layer with 0 vias that isn’t hand wired!






  • Vias 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.
