Use staggered pads instead of inline pads if you have them. Use flip chip instead of wire bond.

I have used staggered pads.

Flip chip will need more money. And I am not familiar with the FC‘s backend flow。

Can you tell me the difference between the nomal wire bonding PR flow and the FC's PR flow?
