Abstract
Alignment of leaded surface mount components to solder pads is enhanced by providing at least two soldered areas per lead, separated by a space of non-wettable material so that during component placement on the soldered areas there is a tendency for the components to self center as the leads fall between the raised soldered areas where they are retained during a reflow operation.
