Profiling Made Easy:
By automating the complex task of process set up the SlimKIC® 2000
makes profiling so easy
that any operator can quickly achieve the optimal process. Simply
select from a
built-in library containing hundreds of commonly used solder paste
specifications.
The software uses the paste supplier’s thermal profile specs to
automatically
define the process window. Color-coded signals alert the operator
to any out-of-
specification conditions.
Profiling Made Fast:
The SlimKIC 2000 features innovative, patent pending technology
that virtually eliminates
the time consuming tasks traditionally associated with temperature
profiling.
Oven zones and mapping of thermocouples on the product are
automated. Process
acceptability is instantly determined, reducing the number of
required profile runs and
minimizing production downtime.
Profiling Made Precise:
The SlimKIC 2000 simplifies profiling by reducing the process to a
single number
— the Process Window Index™ (PWI) — so you know precisely how good
your profile is.
The simplified user interface guides the operator through the
profiling process,
minimizing the potential for improper oven set up and
yield-reducing defects
Profiling Made Painless:
The SlimKIC 2000 takes the pain out of process set up for even the
most
complex products and requirements — including the narrow process
window imposed
by Lead-Free compliance. Eliminate the pain of Lead-Free transition
from your
thermal process, while optimizing product quality and reliability.
KIC Navigator:
™The KIC Navigator option automates the optimization of your
process set up.
Please see the KIC Navigator data sheet for additional information.
KIC Auto-Focus:
™The KIC Auto-Focus option eliminates the guesswork associated with
initial
product set up. Auto-Focus includes KIC Navigator. Please see the
Auto-Focus data
sheet for additional information.

Datalogger Model: data is downloaded to the computer through a
cable after the run.
Dual Unit Model: data is sent to the computer in real-time during
the run. It is also stored internally for high-speed download after
the run.
Note: The SlimKIC 2000 can interface directly with the oven
controller, eliminating the need for manual setpoint data entry.

Profiling Reduced to a Single NumberFor precise ranking of profile
performance, the SlimKIC 2000 uses the Process Window Index (PWI).
The PWI calculates how much of the available process window is used
by a given profile in relation to its process specifications.
Therefore, the lower the PWI, the more efficient and stable the
process! (See the PWI data sheet for a detailed explanation)

Test Procedures
Listed below is the step-by-step procedure we followed in testing
the SlimKIC 2000 with Auto-Focus. Note that we followed this
procedure 40 times (20 different boards and 2 different ovens):
Input the length, width, and weight of the product. Auto-Focus
determines the best first oven recipe. If there were not enough
boards in the database for Auto-Focus to determine a best first
recipe, we simply used the recipe that the oven was already
running.
Attach thermocouples to the board and run it through the oven using
the SlimKIC 2000 to record the thermal profile.
The PWI (Process Window Index) for the thermal profile is
automatically calculated and the Navigator software tool
automatically searches for the oven recipe that will provide the
lowest PWI. If the actual PWI is less than 60% the oven is
considered setup for the board. If the actual PWI is greater than
60%, but the Navigator can improve it by at least 20 percentage
points, then use the Navigator oven recipe and go back to step 2.
Notice in the above procedure that the testers do not need to make
any “decisions” during the testing. The SlimKIC 2000 and Auto-Focus
specify the setpoint temperatures and conveyor speed to use, and we
follow a simple set of rules to determine when the profile has been
optimized. This simplifies the training of the testers because they
do not need any understanding of the relationship between the oven
settings (setpoint temperature & conveyor speed) and the profile
statistics (peak temperature, maximum rising slope, time above
reflow, etc.).
BTU Paragon 150
We started testing in the BTU Paragon 150. This is the more modern
oven we used for our testing, built in September 2000.
Since this is our first board, the database was empty and
Auto-Focus could not give us a “first guess” recipe for the first
profile. We simply used the recipe the oven happened to be running.
It took three profiles for the SlimKIC 2000 find an in spec oven
recipe for this board:
Results from the three profiles that were required to get the first
board in spec
From the above table, notice that the PWI of the first profile was
231%. Since we have to be below 100% to be in spec, this oven
recipe is well out of spec. The Navigator then suggested an oven
recipe that should lower the PWI to 52%. We let the KIC 2000
software automatically copy this suggested recipe into the BTU oven
control software. We waited until the oven stabilized on this new
oven recipe and then we ran a second profile. The second profile
had a PWI of 102%. This time the Navigator found an oven recipe
with a predicted PWI of 60%. We used the suggested recipe and ran a
third profile. The resulting PWI was 67%. At this point we quit,
happy that the KIC 2000 software had found an oven recipe that
would process this board in spec.
