Abstract: A circuit board fastening system consists of a two-piece assembly including an electrically conductive circuit board retainer for surface mounting and a flexible clip for retaining a daughter-card to the retainer. The clip is preferably made of a flexible polymer so that a band portion in the middle of the clip can be comfortably folded 180 degrees at a u-shaped bend. During assembly, an arrow-shaped barb at one end of the clip is inserted into a retain bore thereby resiliently securing the daughter-card to a retainer flange upon which the card is seated. At the opposite end of the clip, a notched aperture in the clip is affixed around a groove in the retainer flange. The resilience of the barb provides a residual clamping effect to the daughter-card that is tightly sandwiched between a broad planar portion of the clip and a top surface of the retainer flange.
