6-3.1 Process Control/Validation Feature

Figure 17:  Process Validation

During the Profile Development phase, a temperature probe trace can
be saved with an associated profile.  A reference point near the
component rework area (on an adjacent component lead for example)
must be used for temperature probe placement.  Location can be
stored in “Profile Instructions”.  Keep in mind that data must be
collected from the same Temp probe place at the selected location
when saving profile temperature and rate with the profile.

When an operator selects an appropriate profile, the temperature
probe trace will be displayed on the graph in blue.  To validate the
rework process, the operator can place the temperature probe on the
designated reference point, check the box next to Sensor 1 in the right
hand margin and run the profile.  As the profile progresses, the
temperature probe trace will be displayed in red.  The two probe traces
can be compared to validate a particular rework process.  (See Figure
17)  Some variation may exist due to differences in Temp probes,
positioning, and operator error.  The “shape” of the curves should be
similar.
