Sure! But they warm up slower than everything else, so it's not a big deal. You can taylor your profile around them and never exceed your 50 second threshold.

JDumont is right on the money. With today's modern reflow ovens and closed-loop feedback systems that alert you when something's out-of-whack, I have yet to find an out-of-tolerance condition on a known-good profile.

Does anyone out there have experience reflow profiling with a Heller 1500SX? At my past places of business, I had an ECD Super MOLE, and I got pretty reliant on it. Need some help getting to where I need to go with this software. Thanks in advance

Thanks This error only occurred with one oven profile with the reflow zone temperature set at 270�C. Perhaps it really has to do with the exhaust pull as the oven is operating very near its temperature limit with this profile. I will check that. Tha

Try this. Basic reflow profile build up and explanation of its parts: ramp-up, soak or no soak, peak, cooling. Good starting point.

Take a look at your profile. Early on in the development of our leadfree process we saw excessive voids on BGA'S. We tweeked our reflow profile and were able to bring our voids down to about 9% or less. Also found that some paste mfgs. worked better

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.

hi, thanks for yr feedback. we are a repair house..for us making profiles using expensive techniques is not possible...so we are looking for fast and easy to go methods. regards
