Good Morning TechNet!
I would suggest contact KIC Thermal Profiling: 619-673-6050
15950 Bernardo Center Drive Suite E San Diego CA 92127
Their systems work on both wave and reflow. The "predictive" algorithm
they use isn't perfect but does a solid job of getting you within a
couple of tries of the optimum process settings. I have found that the
use of a "predictive" software tool is minimal - I only go to that
effort if the assembly has unique design features or there is a defect
trend problem. In practice, I compare the new assembly to my current
assembly profiles and develop the profile on the fly (about 99% of the
time). The time spent typically is no more that 45 minutes.

We are investigating the feasibility of a software tool to predict
the reflow soldering profile. As input we want amount and type of
components, print parameters (thickness, layers, area etc.). As output:
conveyor speed, the different temperatures and convection % for our
hot air reflow machine.
Does anybody know tools that can accomplish this? If not, are you
interested in the results or do you just want that bright and shiny
solder joints (target condition class 3)?
