Test current is 0.5mA max. And the DC voltage ascends up within 100V/s(Vs＜1000V) or 500V/s(Vs≥1000V). Measure the insulation resistance across the terminal at regular voltage. But the test voltage doesn’t over the DC spark-over voltage. Measure the electrostatic capacitance by applying a voltage of less than 6V (at 1KHz) between terminals. Rate-of-change, within±30% insulation resistance & capacitance, conformed to rated spec. 10KV with 1500pf condenser is discharged through 2KΩ resistor. 200 times at an interval of 10sec. ∣△Vs/Vs∣≤30% Characteristics of other items must meet the specified value 1.2/50μs & 8/20μs, 3000A, electrically connected with a resistor (1~2 Ω), ±5 times, each time interval 60 seconds. Thereafter, outer appearance shall be visually examined. Measurement after -40 ℃ /1000 HRS & normal temperature/2 HRS. Measurement after 125 ℃ /1000 HRS & normal temperature/2 HRS.

Apply flux and immerse in molten solder 230±5℃ for 3sec up to the point of 1.5mm from body. Check for solder adhesion. Measurement after lead wire is dipped up to the point of 1.5mm from body into 260±5℃ solder for 10sec Apply 0.5kg load for 10sec Bend lead wire at the point of 2mm from body under 0.25 load and back to its original point.

Hand Soldering Solder iron temperature: 350±5℃ Heating time: 3 seconds max. General attention to soldering u High soldering temperatures and long soldering times can cause leaching of the termination, decrease in adherence strength, and the change of characteristic may occur. u For soldering, please refer to the soldering curves above. However, please keep exposures to temperatures exceeding 200℃ to fewer than 50 seconds. u Please use a mild flux (containing less than 0.2wt% CI). Also, if the flux is water soluble, be sure to wash thoroughly to remove any residue from the underside of components that could affect resistance. Cleaning When using ultrasonic cleaning, the board may resonate if the output power is too high. Since this vibration can cause cracking or a decrease in the adherence of the termination, we recommend that you use the conditions below: Frequency: 40kHz max. Output power: 20W/liter Cleaning time: 5 minutes max. SOCAY Electronics Co., Ltd.
