yes, You need tell us how the PCB and board designed, size, material, how de-paneling the PCB?

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

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.

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?

at first , you need to optimise your panel design ( lenght width & postage stamp ) , use an anti-buckling cable during first reflow , and you can put trays under your panel during first reflow..

Hi, 1. I will run the board on the mesh if single sided. 2. For double sided board, I will try stiffeners. 3. If stiffeners don't work, then you have to create a handling fixture(holds the board and has enough openings to let the air flow to the PC
