Softbank Mobile Corp's 920SH is sold with various catch lines such as "3.2-inch full-wide VGA LCD," "16:9 full-wide screen" and "4th-generation AQUOS mobile phone."

With a design oriented to a slimmer body, the handset has a chassis measuring 18mm in thickness, which is about 5mm thinner than that of the existing models. What kind of tweaks are there inside the chassis to reduce its thickness?

The Nikkei Electronics Breakdown Team removed a back lid and unscrewed the screws. A sticker bearing a logo, "QUALCOMM 3G CDMA" was attached on the back surface.

After removing the back surface, the mainboard appeared without difficulty. As with the P905i, it was based on design concepts such as integrating card slots on the sub-board as well as providing a rod antenna for 1seg reception and the main antenna on the back chassis.

The chassis on the keyboard side seen from the back: To reduce its thickness, buttons were provided integrally with the chassis.

We removed a metal shield on the sub-board to find another shield. After prying it with a knife, a module mounted on a cream-colored board appeared. It was likely a 1seg tuner module using an LTCC board. With the provision of double shields, etc., Softbank Mobile has taken careful measures against radiation noise from the mainboard and other components.

A number of chips bearing white and black stickers were mounted on the mainboard. A metal frame was used to separate the digital baseband processing block from the block for the RF communications circuit, etc.
