Both lead wires are dipped into 350 10C solder for 3.5 0.5 seconds, or 260 5C solder for 10 1 seconds according to Fig-1 (solder <JIS Z 3282 H60A>). Resistance to Resistance (R25C) fluctuation rate: less than 1%. 7 Soldering Heat B-Constant (B25/50C) fluctuation rate: less than 1%. 5 1 to 2mm Solder Fig-1 Both lead wires are dipped into flux (25wt% colophony <JIS K 5902> isopropyl alcohol <JIS K 8839>) for 5 to 10 seconds. 8 Solderability More than 90% of lead wire surface shall be covered by solder. Then both lead wires are dipped into 235 5C solder <JIS Z 3282 H60A> for 2 0.5 seconds according to Fig-1. The lead wire shall be inserted in a 1.0mm 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. Lead Wire Resistance (R25C) fluctuation rate: less than 1%. 9 Pull Strength B-Constant (B25/50C) fluctuation rate: less than 1%. 1N (10 sec.) Fig-2 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. Lead Wire 10 Lead wire does not break. Bending Strength 10N (3 sec.) Fig-3 * R25 is zero-power resistance at 25C. B25/50 is calculated by zero-power resistance of Thermistor in 25C -50C. After each test, NTC Thermistor should be kept for 1 hour at room temperature (normal humidity and normal atmospheric pressure). Continued on the following page. 26
