When I search for milling, I get milling machines. When I search for router or routing I get something to do with traces.
I’m looking for Digikey’s convention for the Kicad board layer where milled or milled-out features for a footprint are drawn and then exported for pcb manufacture.
For example, digikey part number 1684-1001-ND has a smt carrier board with the component sticking thru the board 0.073" according to the datasheet. The datasheet shows the recommended footprint with a ‘routed-out’ feature that will allow this part of the component to stick thru the ‘mother board’ and allow it to be soldered down. This feature is missing in the current Digikey Kicad library and I’m attempting to add it. I’m assuming, without searching, that this issue has happened with other parts and I’d like to know if there is a convention as to which Kicad layer these milled-out features are drawn on. It makes sense that they should be part of the component footprint…Any info or experience would be helpful before I just ‘try something’ and work it out with the board house.
