Ball SACs are not hard to over come. Most people solder these devices well using a straight ramp with a slight knee right before liquidous. Ramp-soak-and spike would not an ideal way to reflow.....

Hi Larry, Typing in all caps is consider yelling in forums. As for your stones, have you tried soaking the old ones in iso to clean them? This should make them last a long time. You may be paing a higher price for stones since they a no longer

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

Dear all, I would like to learn from all regarding purpose of each profile stages, such as preheat, soak, peak cooling. At what stages, flux start to be activated? Thanks for your time,

Can you implement a longer soak? how many feet of heat do you have in oven? Russ

the paste is necessary for the component that had no glue. btw, for solder paste specs, 150C is at reflow time plus soaking time and i believe it will cause nothing to the glue and can cured as per recommended? correct me if i'm wrong.

We roll ours up, fingers and all, and soak them for about an hour in a solution of water and DOMINATE (heavy duty degreaser) you can order from Grainger. They come out looking brand new every time!

Exactly what should I look at in my reflow profile? Soak Times, TAL, Peek?!? I am right in the middle of the manufacturing specifications as far as my profile goes.

I've had some luck with longer soak. Of course that was on a board with severe thermal mismatches so I don't know if it will help your problem or not.
