LPS33W Reflow profile unclear

0693W000007D21tQAC.pngHi.

According to the DS of the LPS33W - the Reflow profile should be according to JEDEC J-STD-020 , with no actual determination of the profile.

we had several boards assembled , and with very little force applied, the sensor disintegrated - the metal part from the plastic socket.

I suspect it might be the reflow profile that weaken the glue and caused this disintegration.

Is there a recommended profile for the LPS33W?

We have used before that the STEVAL-MKI205V1 - which is the LPS33W EVB ,

And had no such issue.

The pic below is of an actual reflow performed on the boards.

Thanks.
