So, these days I was trying to figure out what the dimensions of the final PCB might be, and it seems to me that it might be a little too big. So i was thinking about a solution in order to not take up too much space in width with the components.
So I thought about the motherboard of the most recent iPhones, and I remembered that their PCBs are made up of several boards stuck on top of each other.
Since the missing components (such as those of the G.C +, or the U-Amp 2) are very thin, I could use the Iphone method, but instead of having small pads like the ones of a CPU, i could create some circuit boards whit castellated holes. Basically I would be using the same method I used to relocate the Bluetooth chip on the test board.
I'm thinking about using this method because I'm worried that by putting every component on a sigle PCB (included the ones from the screen driver board) I would end up by having a large circuit board. I Also thought about keeping the screen driver board as it is, but it would take away quite a lot of space in height. This are just some options that I've been thinking to, but I won't be able to take a decision untill I got all the components.
