ABSTRACT:
A method for customizing a printed circuit board comprises steps of registering a template to the PCB, the template having an opening in registration defining a volume on the PCB where a conductive trace or jumper is desired, placing a semi-liquid conductive polymer in the opening, removing the template, leaving a conductive polymer trace or jumper on the PCB, and curing the conductive polymer. The method is applied to load boards for IC test apparatus and to unique receptacles for coupling test sockets to load boards. Receptacles according to the invention have decoupling capacitors mounted through the receptacle, providing capacitor connection very near leads for devices under test in such apparatus. In an embodiment of the unique receptacle, a power plane is provided as well as a ground plane, allowing the receptacle to provide complete customization for more generic load boards. In another embodiment, power and ground sensing lines are brought to the unique receptacle as well.
