        Manufacturing process

             Resistors are formed within a plane of circuit using standard subtractive print and etch board processing
             The product can be processed by any PCB manufacturer using conventional processing equipment and chemistries
             The nominal resistor tolerance, as printed and etched, is typically 10%, but resistors can be trimmed to higher tolerances
               such as 1% if required
             The PCB manufacturer uses artwork to define the geometric patterns that are imaged, then etched to create the resistors for use
               on external / internal layer
             The product can be processed by any PCB manufacturer using conventional processing equipment and chemistries

             The PRT is a thin film metal alloy system that consists of 2-layer bi-functional cladding
             The lower layer located against the base laminate is an electrical resistive material
             The 2 layers of this bi-functional cladding are in contact over the entire area
             Using standard subtractive PCB print and etch techniques, layers are differentially defined so that different patterns of conductors
               and resistors are formed
