Solder Temperature

"T" backed gages with Option S , and "S" Series gages, have dots composed of +570 deg F (+300 deg C) lead-tin-silver solder. Micro-Measurements wire solders have melting points ranging from +361 to +570 deg F (+183 to +300 deg C); the most common are the +361 and +570 deg F (+183 and +300 deg C) solder wire with rosin-core flux. Solid wires are also available, including a popular +430 deg F (+220 deg C) type.

A temperature-controlled soldering station, such as the Micro-Measurements Mark V or Mark VII Soldering Unit, is recommended. Tip temperature should be high enough to assure good wetting of the solder but not so high as to remove the dots, vaporize flux, or hinder keeping the iron properly tinned and clean. Unfortunately, most uncontrolled irons are quite capable of tip temperatures in excess of +900 deg F (+480 deg C), which is much too high for general strain gage soldering.
