We need more information to give you a good answer. Is this a leaded part (axial or radial) or smt? How big is the part, how much weight per lead? What is the end use environment, will it see any vibration? or temperature extremes? Some general com

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

OK, you can't glue, Pallet Guys pallets are out the door, dual line reflow prevents from any lower temp solder paste.... Do you have a 3D printer? Are there parts underneath the connector in question? Measure the PCB thickness, pint out a custom hold

=0.08g/mm2, make it less than 0.08. And maybe the connector gravity center location is a cause also. If no machine issue (vibration, wind,etc), and you cannot change the design/material then you can use SMT glue to fix the connector during reflow.

If you are a CEM you are setting yourself up for failure and will be left holding the bag. Flash gold has one purpose. It is a protective coating for the base medal to keep it from oxidizing. It is very thin and will be absorbed into the solder joint

These are the hold down clips for the connector. I'll post the top side picture asap.

My first thought is board warp. This is something you can't see when the board is in a reflow oven. I see it occasionally going through wave solder. You may need a pallet with hold down clamps for reflow. Try putting a bare board in a baking oven at
