ARROW-MEX: ADP5300 ISSUE

  Hi this about a project we have with a client please if you
could assist: As you know, we are implementing the ADP5300 on a IOT solution.
The boards received, except one, have really low output impedance (50-250
Ohm).  I started the qualification
process with the good one (Zo= 5MOhm). Using some connection wires the PSU was
checked at no-load condition (Vin= 5.0V; Vo=3.279V). Unfortunately, after
soldering some measuring wires at the input and output, the board is not
working anymore (Vo= 0V; Zo= 20Ohm)  The
junction profile was verified and it matches to the Analog Devices suggestion
for the ADP5300 package

possible, Can you help us?
