ABSTRACT:
Techniques for preventing electrostatic discharge (ESD) and circuit noise are provided. More particularly, the present invention provides a method to prevent ESD damage during the assembly of computer disk commonly called a hard disk for memory applications. The coating mainly involves a ion-deposition process. Merely by way of example, the present invention is implemented by using filtered cathodic vacuum arc (FCVA) with a dissipative crystalline and/or amorphous carbon base thin film coating on a flexible circuit to drain the potential electrostatic charges during circuit assembly and interconnect processes, yet it would be recognized that the invention has a much broader range of applicability on any electronic apparatus that is susceptible to electrostatic damage and static noise.
