I am using an STM32 microcontroller component in my design and getting lots of clearance errors. I am using default eagle DRC file and haven't modified anything in the library.
The library, schematic and brd file is attached. Thanks in advance. View attachment Test_board.7z
your spacing between the pads is about 0.2mm. There is nothing obviously wrong with the package.
I assume the DRC setup says it needs more than 0.2mm spacing.
Usually the PCB manufacturers have no problem down to 0.15mm.
So i recommend to adjust the DRC setup.
Go to the PCB manufacturer´s website and look for design rules. Find the values and edit/create a "Manufacturer_name.DRC" file.
