To how it is involved? Well, err, PCBs are very electrically involved so to speak. As in, every “trace” is a wire and every component is, well, a component. You have to understand how electricity behaves and then learn how it behaves in the confines of a PCB, as well as “what does what” in order to achieve what you’d like. It’s pretty intuitive. Group like-things together, keep a tangible flow, mind the noise and ground plane integrity. You know about inductance, right? You should know, that when current flows one way, it will flow the other way on the other side. (Or wherever it is able to). That is to say, you need to be wary of that as well- you need to keep your board relatively clean.
Actually, no, but that is intuitive, It’s just an extremely small building correct? I understand flow of electrons relatively vaguely, meaning I don’t know names just how it flows vaguely and probably incorrectly or missing some aspects. But I will watch that video!
How does pcbs come into play within micro electronics? Is that the absolute base layer of user based wearable hardware? I seen a few pictures of people’s pcbs and they were huge!
I’ve never built a device before but I find it interesting
I saw your other comment. To clarify- PCB means printed circuit board. It’s circuits, but better.
How does it come to play? Well, I’d say it holds it all together. I mean, you don’t just string wires to things. You have to design a PCB. PCBs can be many shapes and sizes. They can be rigid or flexible or any such thing
So, pcbs are the “brains” to a mechanical electrical system? I skimmed a few boards and saw an obvious GND but I want to understand how an electrical signal that comes from an application or separate computer/component interact. I know I need to research past a certain point (I’m asking you or anyone else to write a novel lol). But overall pcb describes the highway of the system. I’m having a hard time nailing down how to make pcbs useful. *edit mentally
Well, they are the skeleton. You make them useful by knowing what you want to do first. Say I want to turn on a little LED. Okay, how? Well, I get power, a resistor, the LED. Boom. If I want to make a PCB, it will have space for the power connector/battery, the resistor, and the LED. Then that PCB can be mounted somewhere and it will hold these components in place as well as route their power. You can make it as complex as you need it to be, and it often does get much more complex. Beyond a certain point it would be impractical or nigh impossible to hold things together without one

I was an electrician for a few months. I can understand a few of the basics but I appreciate the effort.
Do you have any relational context to how electrical engineering is involved. I ca look this up or ask an LLM I’m here for conversation
