Hi Miyano

Solder shift has been performed on a 8 layer FR4 board. Rounting and soldering has been done as per the data sheet recommendation .
We do the solder shift only with one reflow. We have thermal hysteresis for 2 cycles whcih also shows the settling impact.

Can you please let me know the reason for multiple reflows.

Regards

Hi Trailokya

Thank you for your reply.

Double sided mounting means that "Mounting components on both sides of the board".

HI Miyano

There should not be any problem from the device side, provided you are taking care of via and routing properly if you are driving any dynamic load. \
