When the Thermistors are immersed into a cleaning solvent, make sure that the surface temperatures of the
devices do not exceed 100°C.
Performing reflow soldering twice under the conditions shown in the figure above [Recommended profile of
Reflow soldering (EX)] will not cause any problems. However, pay attention to the possible warp and bending of
the PC board.
When hand soldering Thermistors, a large temperature gradient between the preheated Thermistors and the tip
of the soldering iron may cause electrical failure and mechanical damage such as cracking or breaking of the
devices.
Soldering shall be carefully controlled and performed such that the temperature gradient is kept at a minimum
with the following recommended conditions:
(1) Condition 1 (with preheating)
Preheating
(a) Soldering:
(b) Preheating:
(c) Temperature of Iron tip: 300°C max.
(d) Gradual Cooling:
Recommended profile of Reflow soldering (Ex.)
Recommended profile of Hand soldering [Ex.]
f1.0mm Thread eutectic solder with soldering flux* in the core.
*Rosin-based and non-activated flux is recommended.
The Thermistors shall be preheated so that the “Temperature Gradient” between the devices and the tip
of soldering iron is 150°C or below.
(The required amount of solder shall be melted in advance on the soldering tip.)
After soldering, the Thermistors shall be cooled gradually at room temperature.
