4. After installing chips, if solder is excessively applied to
the circuit board, mechanical stress will cause
destruction resistance characteristics to lower. To
prevent this, be extremely careful in determining shape
and dimension before designing the circuit board
diagram.

5. When the positioning claws and pick up nozzle are worn,
the load is applied to the chip while positioning is
concentrated to one positioning accuracy, etc. Careful
checking and maintenance are necessary to prevent
unexpected trouble.
6. When correcting chips 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 done to prevent the
electrode erosion.
7. Do not clean or wash the component as it is not
hermetically sealed.
8. In case of covering filter with over coat, conditions such
as material of resin, cure temperature, and so on should
be evaluated well.
9. Do not use strong acidity flux, more than 0.2wt% chlorine
content, in re-flow soldering.
10. 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.
