Abstract

A flexible substrate for a flexible circuit provided by a substrate having a thickness in the range of 25 microns to 60 microns including at least one zone where the thickness of said substrate is reduced to less than 25 microns. The reduced thickness zone may be defined by laser skiving. The flexible circuit is being used as a flex-on-suspension (FOS) circuit for the electrical interconnection of the read/write head of hard disk drives.
