Hokuriku Electric Industry Co., Ltd.
This time, Hokuriku has developed ultra-micro
size chip resistor.
Along with further miniaturization
of application products such as cellular
phone or digital camera, we are adding
the
ultra-micro size chip resistor in our
resistor
line.
We have achieved ultra-micro
size
to 0.4mm×0.2mm×0.12mm (thickness),
as well
as extremely high precision to ±0.02mm
in
dimensional tolerance. In order
to
achieve them, we have employed slice
method
technology, instead of conventional
chocolate-break
method which is used for 1.0mm×0.5mm
size
or bigger. The slice method was firstly
used
for 0.6mm×0.3mm size chip resistor.
By using metallic thick film for resistor
element, it has excellent climatic
resistance
and durability. It yields good solderability
by reflow soldering and is adaptable
to further
high density mounting.
- Its micro size, 0.4mm×0.2mm is suitable for high-density mounting.
- Its dimensional tolerance, ±0.02mm is highly precise.
- Reflow-soldering can be employed.
- By using metallic thick film for resistor element, it has excellent climatic resistance and durability.
