Example of DVC's countermeasure against
unnecessary radiation
The data shown here are examples of in-house meas-
urement and may not coincide with performance in
other situations.
Along with the outstanding advancement of
digital circuits, efforts are being made to de-
velop smaller and faster digital devices like
DVCs and DSCs. Developments using three-
dimensional high-density structures and high-
speed interfaces are also underway, and efforts
here are taking place at an increased speed.
Sophisticated and precise designs posed limi-
tations on the conventional EMI counter-
measure methods using noise-reducing com-
ponents, shields, and the grounding method.
Flexield offers the advantage of solving prob-
lems without modifying the basic design in the
case of unexpected events during the final
stages of device development. The electro-
magnetic loss and magnetic shield effects of
Flexield can greatly reduce the noise elements
previously irremovable with conventional com-
ponents and methods.
For instance, in this evaluation of a small digital
camcorder, we installed 0.05-0.5mm-thick IRL02
and IRL03 material sheets in such places as on
the small circuit (two locations) where visual
signals from the CCD are processed at high
speed ; on the FPC ; on the top of the con-
troller IC where the FPC are close together when
installed in the circuit board ; on the surface of
the LSI on the unit board ; on the surface of the
FPC connecting circuits; and so forth, a total of
fourteen sites. These locations are suspected to
be the source of high-frequency radiation, and
the secondary radiation due to coupling inside
the case. As a result, unnecessary radiation be-
tween 200 and 1000MHz was reduced by 2-7dB,
including the steep noise elements which had
previously exceeded the VCCI class B regula-
tional value. It was also confirmed that this
method would cause no deterioration of the
unit's basic functions, features, and errors.
