Abstract

A capacitor is attached to a landless printed circuit (PC) board by ribbon leads that eliminate the surface soldering required for attaching or removing the capacitor. By altering the ribbon lead 11, enough mass is present to aid in the heat transfer and the capacitor 12 can be attached directly into the plated through holes 13 of the PC board 14. The lead 11 has a stand-off section 15 that holds the capacitor 12 above the board surface 14. This allows a tool, like a soldering iron, to be placed against the section 15 to remove a defective capacitor. It also allows sufficient clearance for cleaning after soldering.
