PROCESS DEVELOPMENT

Figure 15.

THERMOFLO REFLOW PROFILES

SUGGESTED STARTING PARAMETERS

This chart provides a base starting point for the development of exact parameters ("Established Profile Guidelines") for your
surface mount rework process. Initial tests using these references may not result in complete solder reflow. Adjust the
reference values as necessary to obtain desired results.

Procedure:

1.
2.
3.
4.

Select the Component and Substrate which best matches your application.
Perform a test using the base parameters.
Adjust parameters as desired and perform aditional test runs.
When desired results are achieved, record process on a copy of Profile Control Chart or Profile Log.
NOTE: Blower Speed parameter is base reference for Reflow function.
