Hi Jean-Samuel.

As known, hardware developing impossible without soldering iron.
With UmTRXv2 I found that was used very infusible solder paste.
As I understand it is due to compliance to Pb-free.
Nevertheless, could you please to ask fab to use more fusible solder paste .
I ask, because lab users can easy damage PCB due to the local overheat.
For example, I was forced to use simultaneously soldering iron (300 deg C)
and air heater (350 deg C) to solder linear regulators.

Best regards,
Andrey Sviyazov.
