Hey guys and gals, I’m in the middle of designing a “portable-ish” wireless speaker and I’m stuck on the control interface of the thing.
I want the control panel to be a capacitive touch interface, with the PCB as the front panel, and a screen behind it to display stuff, but I don’t know how to draw the cutout for the screen in the PCB.
there a PCB manufacturer, they are dirt cheap for boards less than 100x100mm, but they have little to no information about milling on their site, and I think they’re intentionally trying to avoid my questions. I’ve asked them how would I need to go about for doing this for a week now and no response. There’s somewhere some information about panelizing that says the minimum milling slot width is 2mm, so I’m guessing they have 2mm milling bits and larger, so I’ve made the window with rounded corners (with a radius of 1mm), but I need someone to help me out here a bit.
Do I leave it like this? Do I need to draw milling slots around the perimeter of the window and put in break vias (or what they’re called)? How is this done?

Below is a screenshot of the board view along with the whole eagle project (including the libraries)
