Anchoring member to facilitate fastening daughter boards to a mother board and a method for use

A printed circuit board assembly comprising:

• a mother board having a first side and second side and at least one aperture;
• an elongated body extending in a longitudinal direction and secured in said aperture, said elongated body having a first coupling member at a first end and a second coupling member at a second end, said second end positionally opposed from said first end in the longitudinal direction;
• a first daughter board having at least one electric circuit, said first daughter board coupled to the elongated body substantially perpendicularly to the longitudinal direction with the first coupling member;
• a second daughter board having at least one electric circuit thereon, said second daughter board coupled to the elongated body substantially perpendicularly to the longitudinal direction with the second coupling member;
• wherein the first daughter board and second daughter board are fastened to the mother board in a substantially parallel arrangement with the first daughter board on the first side of the mother board and the second daughter board on the second side of the mother board;
• wherein the elongated body comprises a friction fit surface for securing the elongated body to the aperture of the mother board;
• and
• a positioning flange for positioning the elongated body in the aperture of the mother board;
• and
• wherein during assembly, the elongated body is inserted into the aperture of the mother board in the longitudinal direction until the positioning flange abuts the first side of the mother board and the friction fit surface interacts with the aperture to secure the elongated body.

A method of fastening a first daughter board having at least one circuit element thereon to a first side of a mother board, said mother board having at least one circuit element thereon, and for fastening a second daughter board having at least one circuit thereon, to a second side of the mother board, said second side of the mother board being opposed from said first side of the mother board, said method comprising:

• inserting an elongated body into an aperture until a friction fit surface on the elongated body interacts with the aperture at an inserted position, said elongated body extending in a longitudinal direction;
• coupling the first daughter board to a first coupling member substantially perpendicularly to the longitudinal direction at a first end of the elongated body;
• coupling the second daughter board to a second coupling member substantially perpendicularly to the longitudinal direction at a second end of the elongated body, said first end being positionally opposed from said second end;
• wherein the elongated body is inserted into the aperture in the longitudinal direction with the second end first;
• wherein the first daughter board, mother board and second daughter board are arranged in substantially parallel arrangement;
• wherein the elongated body comprises a positioning flange for positioning the elongated body in the inserted position;
• and
• wherein the step of inserting the elongated body further comprises the steps of:
• press fitting the elongated body using in the longitudinal direction into the aperture until the positioning flange abuts the first side of the mother board.
