How does the delta T on the board relate to the delta T on the component?

Are you using a standard convection reflow oven ? This does not make any sense. I have never heard of anything like this. If you are using a standard oven, then I would say that it is time to get your profiler calibrated.

Hi, Does it really matter what temp the oven runs at as long as the PCB's are profiled correctly? I mean we run boards through all the time to check profiles, so as long as that's ok, would it matter what the oven though the temps where? Regards,

Does anyone have new info on their ROHS PCB delam. problems? We ran two profiles (different from ours) per supplier recommendations with no improvement on this problem. These profiles included a plateau or soak at 190 deg. C for 20 seconds and a sl

Does anyone know of a method other than drilling holes in a board to accurately profile a BGA ?

| I was wanting to know if double sided reflow can be done with a metal plated BGA on topside. We would be running bottom side first. My boss seems to think the only way it can be done is by placing glue dots on the bottomside compoents because the

| | My question is: How does one recognize paladium leads so that the profile can be set properly? | | Dave F | Hi Dave, | It's kinda' subjective, but what I think it looks like is almost like having a nickel appearance to it, it's smoother and

| Hi | I have been conducting my first reflow profiles. Most of the texts that I have read suggest soldering the thermocouples to a populated pcb. I am finding this very difficult. I have been using a high melting point (Sn5 / Pb95) solder and the
