Abstract

A method of assembling a captive panel fastener to a printed circuit board comprises the steps of placing an axially-extending shank of a captive fastener retainer through a mounting hole in a printed circuit board, soldering the retainer to the printed circuit board, cooling the retainer, and then affixing a retractable screw assembly including a plastic screw cap to the retainer by snap attachment of the screw cap to an outside surface of the retainer.

Claims (12)

1. A method of assembling a captive panel fastener to a printed circuit board, comprising the steps of:

placing an axially-extending shank of a captive fastener retainer through a mounting hole in a printed circuit board;
