Printed circuit board mounting facility

A facility for mounting an electronic component, comprising:

• a first circuit board defining a plurality of mounting apertures;
• a mounting element associated with each aperture;
• the mounting element including a boss defining a bore;
• the boss having a first surface contacting a major surface of the first circuit board;
• the boss having a second surface facing opposite the first surface;
• a pin received in the bore;
• the pin having a lower portion protruding from the first surface of the boss and into one of the apertures;
• and
• the pin lower portion defining a space operable to capture a portion of the first circuit board;
• and wherein
• the boss includes a protruding element from the second surface, and wherein the protruding element is eccentric with respect to the pin.

A facility for mounting an electronic component, comprising:

• a first circuit board defining a plurality of mounting apertures, each of said mounting apertures being surrounded by circuit board material;
• a mounting element associated with each aperture;
• the mounting element including a boss defining a bore;
• the boss having a first surface contacting a major surface of the first circuit board;
• the boss having a second surface facing opposite the first surface;
• a pin received in the bore;
• the pin having a lower portion protruding from the first surface of the boss and into one of the apertures;
• and
• the pin lower portion defining a space operable to capture a portion of the first circuit board;
• wherein
• the pin has an upper end protruding above the second surface;
• and wherein the upper end of the pin is chamfered.

A fastener assembly for connecting two circuit boards comprising:

• a boss having opposed parallel first and second surfaces;
• the boss defining a bore extending to an opening at each of the first and second surfaces;
• a pin received in the bore and having a first end extending from the first surface and a second end extending from the second surface;
• the second end of the pin defining a space operable to capture a portion of the first circuit board;
• and wherein
• the pin is engaged to the boss, such that when said pin and said boss rotate, said pin and said boss rotate in unison;
• and wherein
• the boss includes a protruding element from the second surface, and wherein the protruding element is eccentric with respect to the pin, such that a visual indication of rotational orientation is provided.
