Figure 18: Profile Development Tab
1) Profile Name and Parameters (upper left-hand corner) – Allows the
operator to select a stored profile and displays time and
temperature settings for each phase of the Reflow cycle.
2) Instruction Box – Provides a means to store and display operator
instructions applicable to the selected profile. Instructions may
pertain to
such items as nozzle type, type of solder paste or flux, reference
position of temperature probe for process validation, and any other
special needs.
3) “New” Button – Clears Profile Name field and resets all profile
parameter fields to 0. Allows the operator to enter the new time
and temperature values for each phase of the Reflow cycle.
4) “Save Profile” Button – Saves profile parameters for the selected
profile. Clicking this button will overwrite existing profile parameters
for named profiles. A pop-up box will appear for new unnamed
profiles.
5) “Transfer Profile” – Transfers the selected profile to the working
memory in the TF 2000. The working memory is profile number 39
on the TF 2000. Profile parameters transferred to the working
memory will automatically be displayed in the LCD window on the
TF 2000.
6) “Save As” Button – Used for renaming profiles and naming new
profiles. A pop-up box will appear when pressed.
7) “Reset” Button – Clears sensor input lines from the graph.
8) “Save Excel” Button – Saves profile in .csv format that can be
opened in MS Excel.
9) “Delete Profile” Button – Deletes the selected profile from the PC.
Deleted
profiles cannot be retrieved.
10) Graph Area – Graphically displays profile parameters (time and
temperature) and sensor inputs. Right Clicking the mouse on any
area of this graph will display the temperature at the point selected.
Left clicking the mouse on any two points will give the temperature
slope rate between the two points.
6-4.1 General Information concerning the Profile Development
Screen
1) The Reflow Graph area displays a representation of the Reflow
cycle profile. Time in minutes is graphed along the X-axis and
temperature in degrees Celsius is plotted along the Y-axis. The
time and temperature axes incorporate a dynamic scaling feature to
optimize the display for extremely short or long profiles. Profile
graphs can be saved with profiles to be used for process validation
by operators while using the Operation screen. Profile graphs can
