The purpose of the present invention is to provide a filling plating system and a filling plating method capable of filling plating sufficiently even if the plating is interrupted between electrolytic plating cells. A filling plating system for forming filling plating in a via hole and/or a through hole of a work to be plated, comprising: a plurality of electrolytic plating cells; and an additive adhesion region arranged between each of the plurality of electrolytic plating cells, wherein solution containing one or more kinds of additive selected from at least a leveler comprising nitrogen-containing organic compound, a brightener comprising sulfur-containing organic compound, and a carrier comprising polyether compound, is directly adhered to the work to be plated at the additive adhesion region.

Filling plating system and filling plating method

The invention eliminates defects generated in a metal filling a through hole of a printed board by changing an angle at which a plating solution is sprayed or by changing a posture of the printed board at a time point in a process of precipitating the metal from the plating solution and filling the through hole with the precipitated metal while the plating solution or air bubbles are being sprayed onto the printed board.
