Method of brush plating on circuit board

                                        Method of brush plating on circuit board

         Brush plating is an electrodeposition process in which not all parts are immersed in the electrolyte. In this electroplating process, only a limited area is electroplated without any effect on the rest.

         In general, rare metals are plated on the printed circuit board in the selected part. For example, areas such as edge connectors. Brush plating is used more frequently in repairing discarded circuit boards in electronic assembly workshops. Use a special anode (inert anode). Graphite, for example, is wrapped in absorbent materials (cotton rods) to take the plating solution where it is needed.
