Technology:
TDK developed a new
technology to insulate an electrode by covering it with resin for smaller clearance
between parts on the substrate. With this technology, the clearance between
parts on the substrate is shortened to one quarter of the present clearance. Accordingly,
it has become possible to cut the area of the substrate to half to put the same
number of parts. First, the company decided to employ this new technology to
ultrasmall condensers, and subsequently to smartphones.
The new technology
is to cover the ultrasmall condenser with insulating resin. Because condensers
used for smartphones have an exposed electrode, small clearance between them causes
a malfunction due to short circuit in time of installing. The new technology
makes it possible to shorten the clearance between condensers to one fourth of
the exiting clearance to halve the required area of the substrate. TDK has filed
an application for a patent of this technology. Please click here for further details in English.
