Profile Planner

You can click on any of the images to see the full size image

Profile Planner is an Excel Workbook Application that allows you to match Solder Paste specifications and Oven specifications. You can then see the Profile that will be generated and how well it will conform to the paste manufacturers specification. From this introduction screen you can

• Add a Paste
• Add an Oven
• Select an Oven and Paste combination and see the Profile
• You can also navigate to key areas on ECD's web sites

The tabs along the bottom allow you to navigate to the

• Solder Paste Specifications Database
• Oven Configuration Database
• Robust Profile Calculator
• Robust Profile Graph
• Instructions
• An abstract of Bob Rooks paper which is the foundation for the Profile Planner

When a Paste is selected, on the Paste specification Tab you can see the Ideal Profile using that Paste. To start, we select the average value or "Reference Nominal" for each specification (i.e.. Ramp Slope) for our calculations. You, as the user, can change this value, "Nominal" and/or any of the individual specifications. You can also add more Pastes to the database and change the Paste being used from this screen.

Currently there are over 280 solder pastes in this list. As we learn of more, they will be added in future updates

• The ability to select another Paste or Oven
• The specifications of the selected Paste, including the Nominal values
  • Cells where you can enter different User Set Values and see, for the calculation, the effect it will have on the Profile
  • The Ideal values using that Paste
  • The calculated values that result using these parameters in that specific Oven
  • Ramp, Soak, and Spike times are generated
  • Time above liquidous is calculated as well as the speed used to generate this profile
  • The ability to hide this data if desired
• The specifications of the selected Oven, dimensions, and where the Ramp, Soak, and Spike Parameters appear in that Oven using the selected Paste
• The graph shows the actual Robust Profile with the Paste Specification Boundaries (triangles)
  • This is the best zone distribution between Ramp, Soak, and Spike regions.
• Below the graph is a visual representation of the ideal profile, the Oven zones, and the robust profile
• The Goodness number is an indication of how well this profile fits this oven. It is not an indication of whether it will work. A higher number does not indicate that this paste will do a better job in that Oven
