Is there a sort of standard method to prevent part loss in reflow? I've had a couple of situations come up recently where we've lost some parts during second-side processing. We're running an Heller 1800, with a mesh belt. Most items process fine,

Hi, The problem seemed to be across multiple batches of boards, so I think they were made correctly, and we don't use a carrier in the reflow oven. However we just moved our equipment to the new factory yesterday, and connect and start turning on

I have never had a problem with any other BGA's that I reworked. I recently found out that the BGA that we are trying to rework is made poorly and warps automatically from the heat. There is nothing that we could do to prevent this. Also the board

Hi Thanks for the input. Problem is only ever the A12 plastic tip (no damage ever seen on any other tool). I suspect we have not helped by skipping the retrim operation when we have changed a part so we'll do that but also I just discovered setti
