Abstract

When electroplating printed circuit boards, it is often desired to deposit metal only at particular regions rather than over the entire area of the board. This typically involves multiple deposition and patterned etching steps which can be costly and time- consuming. In addition, valuable board space is often consumed by running a bus-bar to the board edge, where electrical contact is established via an electroplating rack. The irregular geometries associated with typical bus-bars can also lead to non- uniform electrodeposits in the regions ofinterest.
