Method of applying catalytic solution for use in electroless deposition
An improved method of activating a surface to receive electroless metal plating thereon, particularly for use in activating through holes in printed circuit substrates, in which the activating solution comprising a palladium tin colloid in an acidic aqueous matrix is sparged with nitrogen gas to slo...

| description | An improved method of activating a surface to receive electroless metal plating thereon, particularly for use in activating through holes in printed circuit substrates, in which the activating solution comprising a palladium tin colloid in an acidic aqueous matrix is sparged with nitrogen gas to slow the oxidation of stannous tin contained therein. A dynamic flood conveyorized system to perform said activation is described. |
