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.

Author: [log in to unmask] at ccmgw1 Date: 6/18/96 7:39 AM 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)? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Ivo de Rooij (off-line) Manufacturing Process Engineer SMT/THT @ __ __ @ @ ______ _|________ _|__|_|__|_| _____|_______| ____ |___ | // | | | // | | | || // || | ===| _____ o.|====| |________|o|==========| o. _______ ||____|| _ |=== | ________ | | ________ | |___._| | |_______| | | _ | ||________|| |_|________|_| | | |_____________|______|___| || || || || | | || || || || Fokker Elmo BV Electric and Electronic Aerospace Systems [log in to unmask] [log in to unmask] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~.
