– [Test tolerance plus] and [Test tolerance minus]: These two values define the
range in which the solder waves height test is to be performed. The minus tol-
erance thereby specifies how much of the test is due to be started before the
set offset. The plus tolerance specifies how far the test is due to be run beyond
the set offset to determine the new offset before the test process is stopped.
As minus and plus tolerance values, 700 and 2000 are respectively recommen-
ded.
– [Test offset max.]: This value limits the maximum control power. The offsets
identified in the solder wave height test cannot exceed this value.
