I do the very same but with 4 boards and 55A total load.
board board board board |-| | | |_| | | power Your pronblem is that you use the same supply wire for logic and LEDs. When a bunch of LEDs turn on the problem is not the resistance in the wires but the inductance in them. change your design to have two power circuits one for the LEDs and one for the logic chips, it works in 1000 units built every month here.
