NAME
If the component is new, enter the NAME and if you wish the MANUFACTURER and BATCH
number, these information will be listed in the browser of tests to help you to find any test.
If the component has already been placed in the LIBRARY, Click on the
button of
the "Sample Name"
All of the parameters that have been entered are displayed. They can be modified for this
new series of measurements.
2.2.3.4 DIMENSIONS
Type the dimensions needed in mm following the type selected (see the technical data)
2.2.3.5 FLUX
Type the name of the flux or select it in the list by clicking on the lift button.
The surface tension (Gamma LV) of the flux is linked to the flux selection but you can modify
the surface tension if required.
Use preferably a reference flux well known everywhere by all standards like colophony
fluxes; they are more robust with thermal conditions than no clean fluxes.
The flux shall be changed frequently to keep a constant level of solderability.
It is important to know well the GammaLV value for any couple of Alloy / flux as it is used to
define the maximum force and the wetting angle
The value of the flux surface tension is depending of the flux type here are some values for
common fluxes.
