A selective plating apparatus having a multipitch centerline feed block for delivering a uniform blade of plating solution to a mask and which provides passageways for the drainage of used electrolyte solution. The delivery of a uniform blade of plating solution to the mask allows the mask to be designed such that it controls both the area of sample to be plated and the pitch of the sample.
