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 WaveRIDER® NL 2 pallet material.
In our commitment to continuous improvement of our products, the design of the coupon now includes anchor to our solder thermocouple which fixes it at a 2mm depth. This provides better repeatability, and additionally give better representative solder temperatures.

Existing users of the legacy design can upgrade to the new style NL 2+ coupons, but need to expect a shift in existing data. Legacy design of the coupon remains available should they choose to maintain their measured data sets. |

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.
