Fig.70: The solder nozzle data table. The values for 7 commonly used, rotationally symmetric nozzles are already stored in the fact-
ory. Do not overwrite these values; they serve as reference points for newly added nozzles.
f) On a blank line, click on the [Description] input field and enter a descriptive
text. Basically, it is recommended entering the inner and outer diameters and
the height of the nozzle.
ð If the nozzle is rotationally symmetrical, you can take no account of the [X
[mm]] and [Y [mm]]input fields (0).
ð If the nozzle is not rotationally symmetrical:
g) Determine the centre of the nozzle and enter the values into the [X [mm]] and
[Y [mm]] input fields.
h) Determine the outer diameter of the nozzle and add the measured result [1
mm]. Enter the calculated value into the [Dimension Y [mm]] input field.
i) Determine the height of the nozzle and enter the value into the [Dimension Z
[mm]] input field.
j) From the factory stored nozzles, select one the measurements of which are as
similar as possible to those of the one to be inserted (choose a smaller rather
than a larger nozzle).
k) Record the [Gradient], [Offset cold], [Offset warm], [Test tolerance minus],
[Test tolerance plus] and [Test offset max.] values registered there in the relev-
ant nozzle input fields.
l) To enter the [Test distance [mm]] value:
ð If the inner diameter of your solder nozzle is smaller than 3 mm, enter [2.5
mm].
ð If the inner diameter of your solder nozzle is larger than or equal to 3 mm,
enter the [3 mm] value.
ð If the inner diameter of your solder nozzle is lrger than 8 mm, enter the
[3.5 mm] value.

ü To determine the Wave offset for a wave power of [1%]:
ü You have mounted the nozzle
ü The mounted nozzle has been installed and activated in the Data table solder
nozzle
ü A value of [1%] has been entered into the [Wave power] input field.
a) Enable the solder wave.
b) In the [Module tests] frame, click on the
button.
ð A solder wave height test is performed. As soon as the solder wave
touches the test needle, the [Wave offset] status indicator lights up green.
Wait until the solder wave height test has been completed.
c) In the [Manual movement] frame, click on the
button.
ð The solder pot is moved to the [Service] position.
4 mm
d) Check the height of the wave in the nozzle. With a 1% wave power of the max-
imum value, the solder should be in the middle of the nozzle, about 4 mm un-
der the upper edge of the top. In a narrow nozzle, the solder is drawn by capil-
lary action upwards to the sides, while this effect is slighter in a wide nozzle.
