PCB Design

How can I escape 0.5mm ball grid array pins if the trace spacing and via hole size is not allowed to reduce?

For this sort of routing, you will need to do a ‘via-in-pad’ technology. Essentially, just place the via centered on the pad.

Ask your supplier to offer this on their 6-layer process standard and on a 4-layer board for an extra charge. This is called ‘plating overfilled via’.
