warpage after 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 PCB)

You need to put it in a fixture or pallet to run it in the reflow oven, most common material use here is durostone for the pallets that we run in the reflow oven, we use Durostone CFR767

hope this helps

cheers!
