Abstract: The present disclosure relates to a contaminant shield system. The contaminant shield system may surround an electronic device, such as a local oscillator (e.g., a crystal oscillator), to prevent contamination of the electronic device via coupling material (e.g., under-fill material) creep or wicking. The contaminant shield system includes multiple walls and at least one wall includes a pick-and-place feature that facilitates positioning of the contaminant shield system during assembly of a circuit board that includes the contaminant shield system.

Abstract: An assembly is provided that includes a printed circuit board, a transceiver integrated circuit mounted on a first surface of the printed circuit board, and an antenna module having multiple antennas and that is mounted on a second surface of the printed circuit board. The antenna module at least partially overlaps with the transceiver integrated circuit in an overlap region. The antenna module is electrically coupled to the transceiver integrated circuit via direct passthrough signal connections that extend from the first surface to the second surface. The direct passthrough signal connections are located within the overlap region. Each of the direct passthrough signal connections can be implemented using through-board stacked via structures. The antenna module can include multiple layers of signal routing lines for distributing the signals from the direct passthrough signal connections to the various antennas on the antenna module.
