Alps Electric has developed LIQUALLOY HMSAW series magnetic sheet for
noise suppression & HMSAS series magnetic sheet for RFID. Both
series deliver world’s first level Performance.
There are so many kinds of digital devices in our daily lives. For
instance, the mobile phone becomes ever smaller and thinner while
growing more sophisticated with all-new functions ranging from a TV
tuner for viewing terrestrial digital broadcasting to the possibility
of handling electronic money transactions. Magnetic Sheet is one of the
materials used in these ever-developing digital devices.
Circuit board parts are becoming increasingly dense due to set
products' higher functionality coupled with their smaller size and
thinner profiles. Accordingly, interference from radio waves or
magnetic fields that is unexpected at the designing stage is likely to
occur. So that set products can function correctly, certain measures
for noise suppression should be applied during the limited development
period.
The LIQUALLOY HMSAW series magnetic sheet for noise suppression
delivers the industry's best noise control (µ" = 35), and is
approximately 20% more effective than Alps Electric's conventional
products.
In addition, magnetic sheets are used to efficiently capture radio
waves. In an RFID system, such as the electric money function, radio
waves are influenced by other parts and devices and thus do not reach
the antenna properly. In such cases, the efficiency of the
communication system regarding the capturing of radio waves needs to be
improved.
The LIQUALLOY™ HMSAS series magnetic sheet for RFID delivers the
best highest magnetic permeability rate (µ’ = 100 (13.56
MHz band)) in the industry, with efficiency 25% higher than Alps
Electric's conventional products. Attaching this product to the antenna
of the RFID system contributes to stable performance, improving
communications.
Furthermore, both magnetic sheets can be reprocessed into shapes that
meet requirements of individual set products. For example, these
magnetic sheets can be punched out in the size of a mobile phone's
battery cover or processed like stickers, depending on customer needs.
