At the top of the page "search forum". Just type in "slim Kic". How is the "Old school profiling done"? Just curious. good luck, pr

What are the "incredible" differences? I am curious, I also profile old school and have not found value in "prediction" yet either. Russ

I take it you mean that the Cap "explodes"! If so it sounds like the cap is not rated for the Temperature profile you are using. Check the temp.spec of the part. Check your reflow profile.

Delta T is the temparture different between the highest and lowest measured point on a profile. Ramp and cooling rate should not exceed 4deg c/sec to prevent thermal shock to the components and pcbs. This will also minimise delamination.

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

thanks for the inputs. we are planning to run on fuji nxt i think cycle time will not be an issue. i still have another question if we can still use the same reflow profile for paste? or do we need to create another profile?

Thanks for the information about the reflow profiling its really useful for me to set up my own profile.
