Abstract:
Provided is an electromagnetic interference shielding gasket, which includes an elastomer, a soldering prevention part disposed in at least one region of a side surface and a bottom surface of the elastomer, and an electrode disposed on the bottom surface of the elastomer. Even when solder cream for attaching the EMI shielding gasket to a printed circuit board is pushed from the bottom surface of the EMI shielding gasket by its surface tension and solder-rising, the solder cream stays in the soldering prevention part without moving upward along the side surface of the EMI shielding gasket. Accordingly, the reliability of soldering can be ensured without sacrificing elastic resilient force of the EMI shielding gasket.
Abstract:
A modular material antenna assembly is provided that includes an antenna block having a portion with a shape that interlocks with a corresponding portion of an electrically non-conductive frame and secures the antenna block to the electrically non-conductive frame. The electrically non-conductive frame is attached to an interior of an electrically conductive housing so that the electrically non-conductive frame and the electrically conductive housing form an integrated structure. An antenna flex is then mechanically secured to the antenna block. The antenna flex may also be electrically connected to a circuit board. The frame is designed to support a cover glass for the portable electronic device and may be affixed to a housing. The dielectric constant of the antenna block is substantially less than the dielectric constant of the frame.
