Abstract

See full text

A process for dressing a solder pad removes excess solder from locations that should be free of solder, such as circuit traces, other solder pads, and components near the solder pad being dressed. A first area of a substrate comprises solder to be removed and is heated to a first temperature. A second area of the substrate is heated to a second temperature. A vacuum nozzle is heated to a third temperature sufficient to melt the solder and is scanned across the area to be dressed, melting and vacuuming away the excess solder. The scanning process is controlled using a computer numerical controlled (CNC) machine.
