A technique is described whereby a plating system automatically applies, cures and inspects a plating resist to the head area of taper- headed input/output pins in preparation for plating. In the input/output (I/O) pin-plating procedure, only the shank portion of the pin is to be plated. This requires a plating resist to be applied to the heads of the I/O pins, before the plating, to prevent plating of the head area. The concept described herein provides a means of automatically applying, curing resist material and inspecting the area of the I/O pins which require no plating subsequent to the barrel-plating process. The linear selective pin-plating preparation system, as shown in the isometric view of Fig. 1, consists of three resist application stations 10, and control station 11.
