There are some SMD pads in my schematic that are connected to ground, but do not appear as connected on the board. Any help on how to solve this?
This happens for all pads except 12, which is also weirdly connected
The issue is that the combination of isolate and width settings on your polygon are preventing the pour from connecting.
isolate setting tells eagle how close the pour is allowed to get to any item not on the net. Additionally this distance is affected by DRC clearance rules, net class clearance rules, and isolate settings of other polygons.
width setting specifies the width of the lines used to build the polygon (the fill is actually internally a series of parallel lines).
When you have narrow packages, you often find that the polygon cannot reach the pins because in doing so it would violate its clearance requirements. To solve you either need to change your settings (e.g. reduce
width), or simply manually route the connections.
To manually route you only need to use the
route command to draw a short trace out from the pin - far enough to meet the polygon. The trace doesn't have to connect to another pin, it will connect to the polygon when you run
