Most important factor - temperature. Back in the days I worked for a place without AC, and summer time this paste couldn't make it for more than an hour. In controlled environment you will be safe for hours or even a shift.

In my experience, in a temperature/humidity controlled environment, 1 hour, no big deal. 4 hours still ok. Overnight your pushing the limits but will probably reflow without issues. Any longer, could be a problem. Again, a lot depend on type of past

You need to give us a little more information. 1. What is the size of your panel? 2. Are there any heavy components? 3. What is the thickness of your board panel? 4. What kind of oven are you using? 5. Is it only a recent problem or ongoing one?

if use tray cannot solve the problem, you can change from the design 1）Reduce the effect of temperature on PCB 2) PCB USE HIGH TG 3) BOARD THICKNESS TOO THIN 4) MODIFY THE BOARD SIZE 5) Reduce the V-CUT depth.
