 For tightening screws, if a tightening tool (such as a driver) hits the products, the package may crack, and internal

stress fractures may occur, which shorten the lifetime of the electrical elements and can cause catastrophic failure.

Tightening with an air driver makes a substantial impact. In addition, a screw torque higher than the set torque can

be applied and the package may be damaged. Therefore, an electric driver is recommended.

When the package is tightened at two or more places, first pre-tighten with a lower torque at all places, then tighten

with the specified torque. When using a power driver, torque control is mandatory.

 Please pay special attention about the slack of the press mold. In case that the hole diameter of the heatsink is less

than 4 mm, it may cause the resin crack at tightening.

Soldering

 When soldering the products, please be sure to minimize the working time, within the following limits:

• 260 ± 5 °C

10 ± 1 s (Flow, 2 times)

• 380 ± 10 °C 3.5 ± 0.5 s (Soldering iron, 1 time)

 Soldering should be at a distance of at least 1.5 mm from the body of the products.

Electrostatic Discharge

 When handling the products, the operator must be grounded. Grounded wrist straps worn should have at least 1MΩ

of resistance from the operator to ground to prevent shock hazard, and it should be placed near the operator.

 Workbenches where the products are handled should be grounded and be provided with conductive table and floor

mats.

 When using measuring equipment such as a curve tracer, the equipment should be grounded.

 When soldering the products, the head of soldering irons or the solder bath must be grounded in order to prevent

leak voltages generated by them from being applied to the products.

 The products should always be stored and transported in Sanken shipping containers or conductive containers, or

be wrapped in aluminum foil.
