WaveRIDER 163
SOLDER WAVE
Delta T at Wave: The maximum overall temperature seen on the Top Foil T/C after the
Speed Sensor hits the main wave minus the temperature of the Top Foil T/C as the
Speed Sensor hits the main wave. This records the change in temperature imposed by
the main wave on the top foil of a typical circuit board.
Contact Temperature: The maximum temperature seen on the Coupon Solder T/C
after the Speed Sensor hits the solder wave to a user settable distance after the Speed
Sensor disconnects from the main wave. This settable distance is typically the distance
from the solder wave to the Hot air knife but may be less if it is seen that the hot air
knife influences this temp prematurely. Range is from 0 to 30.5 cm (0 to12.0 in). The
default is that this filter is off so the solder contact temp max is looked for to the end of
the profile data.
Dwell Time (A, B, C): The time measured between the respective sensors entering and
exiting the main wave. This records the total time each of the three sensors (A, B, C)
spends in contact with the main wave.
Contact Length: The Dwell Time at A, B, and C times the measured Conveyor Speed.
This records the total length of circuit board in contact with the main wave at any given
instant while in the wave.
Immersion Depth: This is a function of Contact Length and is calculated based on a
known basic wave shape. This records the height of a free flowing solder wave relative
to the bottom of the WaveRIDER pallet.
Figure C- 2: Wave Height
Parallelism: The Dwell Time at sensor C minus the Dwell Time at sensor A. This
records the contact time difference between the left and right sides of the circuit board,
which is a function of how parallel the bottom of the WaveRIDER pallet is to the crest of
the wave.
