Performing the measurement
Measurement 1
► Hold the measuring device with your thumb and forefinger on its handle.
► (1) Place the measuring device with the point which is opposite the zero value of the scale
onto the flux surface and press down to the base of the cavity.
► (2) Apply slight pressure and roll the measuring device in one direction to the zero value (3).
► Take the measuring device vertically up and out of the flux.
► Determine on the middle roller the point (2) where the flux starts to coat the middle roller.
► Read the value on the scale at this point.
Measurement 2
► Repeat the measurement by rolling the measuring device in the opposite direction as far as
the zero value.
► Read the value shown on the scale.
► Calculate the mean value of both measuring results.

4.6 Testing new flux types
NOTICE
Target group: setup operator
The procedure described is a task that occurs irregularly and should only be carried out by
a trained operator with special knowledge (setup operator).
If you use a new flux, then proceed as follows during the test phase:
► Calculate the relevant cavity for the product.
► Place the corresponding dipping plate in the LDU.
► Fill in the flux.
► Set the application speed.
► Increase or decrease the application speed in steps.
► While doing this, observe the flux surface.
► Reduce the application speed again, if waves, dips or irregularities are formed on the surface.
► Select a long dwell time. This can be reduced later to achieve higher cycle times.
► Select a slow start for the upwards movement of the placement head after dipping. This en-
sures that the component is not lost in the flux.
