Abstract: An improved RF/microwave stripline structure fabricated from a PWB suspended inside of a sheet metal enclosure. The enclosure is formed by top and bottom sheet metal covers each having a plurality of flanges that are coupled to the PWB. The PWB contains identical conductive transmission lines on its top and bottom layers. Plated through holes electrically couple the transmission lines on both layers of the PWB. RF/microwave input and output connectors extend through the bottom cover and are coupled to the transmission lines. Critical dimensions between the transmission lines are controlled by the PWB artwork and are not effected by any misalignment of mechanical parts.

Abstract: A method for providing a mechanical/electrical interconnection between two circuit boards, and the interconnection components required therefore, include a pin and socket each having a tail portion, a shoulder portion and a head portion. The tail portion of the pin is sized so as to fit into a plated through hole of the first board, the head portion is sized so as to allow an automated device to capture the head portion and to rest on top of the plated through hole when inserted therein, and the shoulder portion is sized in relation to the plated through hole so as to rest inside the plated through hole and to allow a predetermined amount of solder to flow under the head portion and down into the plated through hole, but not as far down as the tail portion, thereby assisting in centering the pin in the through hole.
