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.

if you can't change the PCB materials or design at this point, you might be able to reduce it somewhat through the use of fixtures or edge stiffeners. Unless it is a particularly thick board, I don't think the reflow profile would be the issue. The t

You might reduce your panel size, cut it in half and rotate to better utilize your edge clamping/board supports. Tape off your current stencil and see if it improves the print. A new stencil and a little extra handling may be cheaper than tooling.
