board is built (1 hour part preperation time; 4h30 picking parts and reflowing)

when powering up the board I got the same problem as zipiju reported (3.3V short)

using flux i scanned all the asic's ; and noticed some shorts ; fixed!

power up the board ; RED led powered up ; bank 0 power rails OK ; bank 1 power rail  1V not ok (0V)

refluxed asics on bank 1 ; problem is that power rail 1V is NOT stable and asics run SUPER hot! (also the IR and the power inductor) ; anyone got any idea why or where to look ? )
