Abstract:
The method of bonding flying leads is capable of efficiently supersonic-bonding the flying leads to pads of a board and improving bonding reliability therebetween. The method comprises the steps of: positioning the flying leads to correspond to the pads arranged parallel; and applying supersonic vibrations to a bonding tool so as to respectively bond the flying leads to the pads. And widths of the flying leads are wider than those of the pads, and supersonic vibrations are applied to the bonding tool, which is pressing the flying leads onto the pads, so that the flying leads are respectively supersonic-bonded to the pads.

Abstract:
A press-fit fixing terminal is mountable to a wiring board by being inserted into a through-hole of the wiring board, and includes a flat plate section and a resilient contacting section. The flat plate section is made of metal thin plate and double-backed such that an end of the flat plate section is placed on a root side and a bent point works as an insertion tip when the terminal is inserted into the through-hole. The resilient contacting sections sandwich the double-backed portion of the flat plate section such that they are placed symmetrically with respect to the double-backed portion and both of the ridges of the resilient contacting section face outward viewed from the double-backed portion, so that each one of the resilient contacting sections forms a V-shape including an obtuse angle.
