Where in the process? Pick and place should know when it drops something and stop. If during reflow you need to work out why something is dropping/being blown off and solve that issue. And the only reliable way of catching that is going to be AOI.

During the movement of the placemat head, components drop on the PCB. Sometimes machine doesn't give error massage for drop component.

How to manage additional components detection in 2D AOI?
