Abstract: Disclosed is a latching apparatus for a pluggable optical transceiver module, which is configured to enable the pluggable optical transceiver module to be plugged or unplugged by pulling the pluggable optical transceiver module. The latching apparatus of the pluggable optical transceiver module connected to an optical connector and electrically connected to a cage assembly includes: a module housing, which is extended in a length direction and used to latch and fix the pluggable optical transceiver module to the cage assembly; and a clip-type latch, which is assembled through the outer circumference of the module housing and used to release the module housing from the cage assembly by horizontally and vertically moving with respect to the length direction in response to pulling of the clip-type latch when the module housing is unplugged from the cage assembly.

Abstract: A printed circuit board structure for a mobile terminal including a main printed circuit board including elements required for functions of the mobile terminal and mounted on an upper surface of the main printed circuit board, and an auxiliary printed circuit board laminated on the main printed circuit board including at least one element further required for the functions of the mobile terminal and mounted on an upper surface of the auxiliary printed circuit board.

Abstract: An embedded capacitor comprises a first substrate on which a plurality of electrically insulated electrode patterns and a ground pattern are formed, a second substrate separated from the first substrate, a plurality of dielectric layers stacked between the first and second substrates, a plurality of metal layers inserted between the dielectric layers and connected to the electrode patterns of the first substrate, and a plurality of ground layers inserted between the dielectric layers alternately with the metal layers.
