4 WaveRIDER
1.2 Coupon Description
Temperature data about a solder machine is taken from three type "K" thermocouples
(T/C) attached to the Coupon. Their purpose is to sense the impact of a solder machine
setup on circuit board "like" material, as opposed to the RIDER pallet material.
Figure 1- 4: Coupon Description
The "Bottom Foil" T/C is inserted into the coupon as close to the bottom surface as
possible without breaking through. The "Solder" T/C is exposed below the bottom
surface of the coupon so it will contact the solder. The "Top Foil" T/C is inserted into the
coupon near the top surface.
