Wave Solder
The Datapaq Reflow Tracker system – and Insight software – can be used with
both reflow and wave-solder ovens.
In the Wave Solder system, the logger (in its thermal barrier) is mounted on a
flat pallet (part no. CS5000) which passes through the oven. Up to nine fixed
thermocouples on the pallet measure conditions relating to the solder wave: the
oven's line-speed and the contact length of the solder wave, and thus the
contact time with the solder. Up to eight of the fixed thermocouples lie in front
of the logger on the pallet's leading edge (i.e. entering the oven first) and one is
towards the rear of the pallet. The vertical position of the fixed thermocouples
can be adjusted in order to alter the depth of their penetration into the solder
wave. The rear part of the pallet holds a dummy PCB (a 'test coupon')
instrumented with three additional thermocouples which gather data on
conditions in the oven's preheat zone.

and the thermocouples' identifying numbers (see text) are shown. The pallet travels to
the left, into the oven.
