摘要： A pair of elongate rail members are secured along opposed edges of a printed circuit board for protecting the solder fillets formed on the foil side of the board and to facilitate convenient screwless mounting of the printed circuit board to a substantially flat platform of a television receiver chassis or the like. Each rail member comprises a printed circuit board supporting surface and a substantially flat base adapted for mounting on the platform, the base being spaced from the supporting surface by a distance greater than the length of the solder fillets. The rail members are secured to the printed circuit board by resilient tabs which snap lock the foil surface of the board in abutment with the supporting surface. At least one locking member depends from the base of each rail and is received for limited longitudinal movement within an elongate slot formed in the platform, the locking members and base forming a bite for capturing an edge of the platform at one limit of longitudinal movement. The back cover of the chassis includes internal projections bearing against the rails to prevent movement away from the limiting position.
