| The flexure is a suspension
component, which propagates the signal between
the circuit and magnetic head when writing and
reading. (For reference please see chart 1)
The characteristics required for
flexures are:
- low stiffness
- high electrical conductivity
- high accuracy
There are 2 types of manufacturing
processes for flexures, Additive
Type and Subtractive Type. (For reference
please see chart 2)
- Additive Type
This type is constructed by building up
the insulating layer and the conductor
layer on
top of a stainless base.
This type of flexure is called 'CIS'
(Circuit Integrated Suspension).
- Subtractive
Type
This type is formulated with a tri-laminate
made of a stainless, an insulating
layer and
a conductor layer by etching.
This type of flexure is called
'ILS' (Integrated Laminate Suspension).
CIS and ILS each have their
own characteristics respectively and which type
used in a suspension design is proposed according
to which best meets the given customer requirements.
