You might be able to get a limited view under the BGA to check for shorts. If you were to e.g. place a bright light on the edge of the chip where the part number is printed, then looking straight on at the edge of the board where you haven't yet populated the expansion connector you may be able to see light in between each row of balls. You can repeat the process for the other axis. It may need some magnification, but in any case it might help provide a tiny amount of confidence that nothing is shorted.

Здравствуйте.
А почему вы не используйте Altium Designer для разработки печатные платы ? Средства вроде на много раз лучше чем easy Eda
Это очень дорого. Как хобби, я не могу себе этого позволить. 🙂
