2mm length of coating resin from the top of Thermistor is to be
dipped into beads of lead (Pb), and DC100V 1 minute is
applied to circuit between beads of lead (Pb) and lead wire.
Both lead wires are dipped into 350 10 C solder for 3.5 0.5
seconds, or 260 5 C solder for 10 1 seconds according to
Fig-1 (solder <JIS Z 3282 H60A>).
Both lead wires are dipped into flux (25wt% colophony <JIS K
5902> isopropyl alcohol <JIS K 8839>) for 5 to 10 seconds.
Then both lead wires are dipped into 235 5 C solder
<JIS Z 3282 H60A> for 2 0.5 seconds according to Fig-1.
The lead wire shall be inserted in a ø1.0mm hole until resin part
contacts with a substrate as shown in fig.-2, and 1N force for 10
seconds shall be applied to the lead wire.
Hold the lead wires as in Fig-3. Bend by 90 degrees and again
bend back to the initial position. Then bend to the other side by
90 degrees and again bend back to the initial position. After
bending process, 10N force for 3 seconds shall be applied to
the lead wire.
