ABSTRACT:
A method of preparing a large-current printed circuit board comprises inserting a fastener with a bottom flange in a through-hole formed in a printed circuit board so that the bottom flange is engaged with a surface of the printed circuit board, putting a washer having substantially the same outer diameter so the flange around the fastener at the other surface of the board, forming a radial extension at the outer side of the washer by caulking the fastener, whereby the fastener is fixed to the printed circuit board by means of the radial extension and the bottom flange wherein the washer is interposed between the radial extension and the printed circuit board.
