In the analysis tab are the most differences from a placement project to a printer project.
1. In case that there are stencil reference data available, you can activate the calculation of it,
with this checkbox. See 5.2.18.15 Base Data – Stencils
2. Before the measurement is started, the 4 parameters from the printer must be entered in the
fields below the measurement table.
- Print speed: in mm/sec. (25)
- Print pressure: in kg (4)
- Separation distance: in mm. (3)
- Separation speed: in mm/sec. (1)
Print speed and Print Pressure must be adjusted for both printing directions separately,
Forward and Reverse.
3. With each measurement the values from area 1 are being allocated to the measurement spe-
cific parameters.
With this procedure, a history regarding these parameters can be realized for the printer ad-
justment measures.
• Now, start the first measurement:
The printing direction is shown in the list, for each measurement with Radio buttons.
Recommendation with Loctite 3616 and
stencil with 800µm circles in brackets.
You will be directly asked for the printing di-
rection of the measurement.
For the first measurement there is no direction
preselected and you cannot continue, without
selection. On the start of each following meas-
urement, the direction will be changed auto-
matically and set per default. You just need do
check and confirm, or adjust.

4. Multiple selection of SID’s to be analyzed:
Due to the facts described in 4.2.7.1 it is necessary for the printer MCT’s, to select numbers of
measurements at once. Click onto the button “Select” in area 4.
A dialog will appear which helps to Activate/Deactivate measurements:
5. Printer mode:
For printers, the result of the calculations can be getting in 3 different modes.
- Printer mode “Single”:
In this mode, a single measurement is evaluated.
Even if you have selected multiple measurements in the list, in the evaluation views only
one measurement is displayed.
You must select the measurement you want to evaluate from the list of parameter "SID".
The SID can be found in the list, in the column "File Name".
NOTICE
! Comment the measurement !
As far as possible, you should comment each measurement in order to document the
previously incurred changes.
This is useful to find a common thread among the adjustments and, above all, to see
the start and end of each stage (offset adjustment, MFU).
Choose which measure-
ments (from/to) should be
prepared with the actions
beleow.
Choose, if you want to
activate, or deactivate
measurements.
Choose, if the action
should be carried out on
either on “All Measure-
ments”, on the “Back to
Front”, or “Front to Back”.

- Printer Mode “Accumulate”:
In this mode, all measurement points from all selected measurements are evaluated to-
gether.
This means, for example, on a board with 28 measuring points and 20 selected measure-
ments that 28 x 20 = 560 measured values are evaluated.
With printer projects, this mode is for matching the offsets (X / Y) and the stencil rotation
(θ) used.
Step 1 at printer projects: Adjusting the stencil rotation θ (Theta)
4 boards must be printed, 2 in each direction.
These 4 measurements are going to be evaluated in the mode „Accumulate“.
If the printer mode is not “Point2Point”, the value for the stencil rotation is shown in the
top right corner of the “Statistic” view.
Remember to
comment the
measurements!
