To simulate a rework site with an attached component, four layers of 3-mil Kapton tape were used to cover a high response rate thermocouple junction at a bare [micro]SMD site.
Remember that a thermocouple measures the temperature only at the location of the thermocouple junction. If an average furnace temperature is required, more than one thermocouple must be used with a chart recorder to obtain a direct copy of the actual sintering cycle.
A thermocouple gauge contains an electrically heated filament and a thermocouple junction in physical contact with it.
The reduction in RH can be measured via the temperature depression from evaporation of a wet thermocouple junction (psychrometric mode of measurement).
At R = 0, 1.25, 2.5, and 3.75 mm, the thermocouple junction locations in the model with TMC, small rises of temperature, on the order of a few tenths of degrees, are observed (Fig.
The thermocouple junction then could be located with precision using image analysis software.
