摘要:
The invention relates to a fastener assembly for use in attaching articles to printed circuit boards, and include a fastener, which has a generally tubular body, flanged at one end, is adapted to receive a screw. The fastener has a polygonal cross-section over a portion of its length. The flange which is located at one end of the tubular body, has an integral spring washer and includes indentations which allow solder to flow from one side of the printed circuit board to the other. The fastener with its integral spring washer provides improved clamping characteristics and avoids problems associated with large coefficients of thermal expansion of printed circuit board material in a direction perpendicular to the board.
