Abstract:
A high frequency IC package and high frequency unit are simplified and downsized, and the number of manufacturing processes is reduced. The part 9 to determine a characteristic of the high frequency IC chip is arranged outside the sealing 14 of the high frequency IC package 5. The part can be arranged on the package board 7, circuit board 4 or housing chassis 1. When the part is arranged outside the sealing, the package and the high frequency unit 6 on which the package is mounted can be downsized. In the case of arranging the part on the circuit board, the part can be mounted together with other surface mounting parts. Therefore, the number of manufacturing processes can be reduced.

Abstract:
The present invention provides a system and method for employing leaded packaged memory devices in memory cards. Leaded packaged ICs are disposed on one or both sides of a flex circuitry structure to create an IC-populated structure. In a preferred embodiment, leads of constituent leaded IC packages are configured to allow the lower surface of the leaded IC packages to contact respective surfaces of the flex circuitry structure. Contacts for typical embodiments are supported by a rigid portion of the flex circuitry structure and the IC-populated structure is disposed in a casing to provide card structure for the module.
Abstract:
A first power supply layer spreads over an insulating layer outside an island of a second power supply layer. A first ground layer spreads over an insulating layer outside an island of a second ground layer. First and second electrically-conductive pieces are interposed between the first and second power supply layers as well as between the first and second ground layers. A capacitor is interposed between the first and second electrically-conductive pieces. Power supply noise is forced to inevitably pass through the electrically-conductive pieces. The power supply noise thus reliably flows into the capacitor through the first and second electrically-conductive pieces. A printed wiring board is in this manner allowed to enjoy a sufficient suppression of the power supply noise.
