Time (sec.)
(2) Soldering Iron
Lead terminal is directly contacted with the tip of
soldering iron of +280±5°C for 3.0 seconds±0.5 seconds.
2. Wash
The component cannot be withstand washing.
■ Notice (Handling)
1. The component mounted on the PCB may be damaged if
[Component direction]
excess mechanical stress is applied.
Put the
component
laterally to the
direction in
which stress
acts.
2. Layout the components on the PCB to minimize the
stress imposed by the warp or flexure of the board.
3. After installing components, if solder is excessively
applied to the circuit board, mechanical stress will cause
[Component layout close to board]
destruction resistance characteristics to be lower. To
prevent this, be extremely careful in determining shape
and dimension before designing the circuit board diagram.
4. When the positioning claw or pick up nozzle are worn, the
excess load is applied to the components while
positioning or placing are performed. Careful checking
and maintenance are necessary to prevent unexpected
trouble.

5. When correcting component's position with a soldering
iron, the tip of the soldering iron should not directly touch
the chip component. Depending on the soldering
conditions, the effective area of terminations may be
reduced. The use of solder containing Ag should be
considerd to prevent the electrode erosion.
6. Do not clean or wash the component as it is not
hermetically sealed.

7. In case of overcoating the part, coating conditions such
as material, curing temperature, and so on must be
evaluated deeply.
8. Accurate test circuit values are required to measure
electrical characteristics.
It may be a cause of mis-correlation if there is any
deviation, especially stray capacitance, from the test
circuit in the specification.
