check your reflow chain. it maybe vibrating causing DPAK to fall at second reflow.

If all else fails, you can always chipbond the part. Would it be possible to run this side as the second reflow?

During the second reflow, the solder remelts and resolidifies. In general, the reflow temperature is not high enough to erase the microstructure developed during the first reflow. As a result, the net effect of a second reflow typically is grain coar

Which components are falling off during the second reflow?

Traditionally these connectors are riveted to the board on higher volume telecommunication applications. sarason

Reflow bottom side first, reduce heat slightly for second reflow.

we have a problem : The connector is falling down in the second reflow. This connector is mounted in the first side. You can find attached the reflow profil we work with and a photo of the connector. We tryed with under_film but the connector is sti

I need to reflow a two-sided PCB with SAC 305 solder. The bottom side has a BGA128, QFN32, and some small USON packaged components, while the top side has larger components like a QFP100, SOIC20, connectors, and DPAKs. I'm unsure which side to reflow

Would you consider a light reflow pallet on second side holding the connetors in place and preventing them from moving?
