ABSTRACT:
A composition and process for preparing a non-conductive substrate for electroplating. The composition comprises 0.1 to 20% by weight carbon (e.g. graphite or carbon black) having a mean particle size within the range of 0.05 to 50 microns; optionally, 0.01 to 10% by weight of a water soluble or dispersible binding agent for binding to the carbon particles; optionally, an effective amount of an anionic dispersing agent for dispersing the bound carbon particles; optionally, an amount of a surfactant that is effective for wetting the through hole; a pH within the range of 4-14; and an aqueous dispersing medium. Improved methods of applying the composition to a through hole, a printed wiring board having a through hole treated with the composition, and a method of fixing a carbon coating deposited on a through hole using an acid solution are also disclosed.
