Comments on: What is a baseline profile? http://profilingguru.com/reflow/what-is-a-baseline-profile/ Tue, 17 Nov 2009 18:21:17 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Michael Limberg http://profilingguru.com/reflow/what-is-a-baseline-profile/comment-page-1/#comment-20 Michael Limberg Mon, 06 Apr 2009 18:41:18 +0000 http://profilingguru.com/?p=361#comment-20 Glad to see you are looking objectively at your process. You point out a notable issue with production ovens. There is a difference between a “loaded” oven vs. an “unloaded” oven. Generally, the process specification will allow for fully loading an oven and still produce products within specification. In some cases, the PWI will improve when an oven is fully loaded, and drift to the outer limits of the specification when unloaded. I favor an oven setup that behaves in this manner. Most oven recipes can be developed to function in this manner. Taking the extra steps to achieve this balance in the oven recipe is worth the extra effort. We have had requests for a software solution that will adjust oven set points according to the thermal load of the oven and respond to the various changing conditions. Currently, this option is not available with the KIC 24-7 software, or any of the KIC products. However, the KIC 24-7 software will monitor your oven and issue an alarm when the conditions drift out of specification. KIC offers a software solution called “Navigator” which is available for KIC 24-7 and KIC 2000 monitoring and profiling systems. Navigator is a prediction software product that uses the database of the Profile Library, that is part of the KIC 24-7 monitoring system and KIC 2000 Profiler. Navigator may be used before the oven becomes out of specification and allows you to create set points that are in specification if your oven is loaded or unloaded. Currently, changing the set points requires that another baseline profile be ran to verify the set points are still within specification. If enough customers request an interest in a product that adjusts set points “on the fly”, KIC would look into this request. Currently, many customer processes do not allow for KIC products to make changes in this manner. Thanks for your post Miguel. Hope this covers your question.

For manufacturers that cannot stop production this system is fantastic. Also, a good tool to identify problems with the oven zones when the thermal slopes are monitored.
