7. General Information
7.1 Storage
Chip inductors shall not be stored under high
temperature and high humidity conditions.
Especially, do not store taping where they are
exposed to heat or direct sunlight. Otherwise,
material may be deformed, causing problems
during mounting.
7.2 Mounting
Placement force should not be excessive.
7.3 Soldering
Soldering should be done at 250°C for less
than 6 seconds. When using a soldering iron,
temperature shall not exceed 350°C and
within 3 seconds. Soldering iron time shall
be allowed only one time. After soldering, chip
inductors shall not be stressed excessively.
7.4 Cleaning
There is no problem using organic solvents.
Since these chip inductors are a coil of
ultra-thin wire, they are susceptible to
vibration. If an ultrasonic cleaning unit is
used, check for any possibility of problem
generation before practical use, since such
cleaning units differ considerably in vibration
level and mode. Although the conditions
vary depending on the printed board size,
Ultrasonic cleaning is generally used in
the conditions described in the following
examples:
Power: Within 20W/L
Cleaning times:
Within 5 minutes
7.5 Pattern Design
A land pattern gap is recommended of
2.0 mm to 2.5 mm. When low or more chip
inductors are closely mounted, they must
be separated by means of solder resists
to prevent excessive solder.
9. Land Pattern Design
9.1 Pattern Design
A land pattern gap is recommended of
2.0 mm to 2.5 mm. When low or more chip
inductors are closely mounted, they must be
separated by means of solder resists to
prevent excessive solder.
