Basic
Types of Flexible Circuit:
There
are five basic types of flexible circuits as described below:
1.
Single-Sided Flexible Circuits
This
is the simplest type, and consists of a thin and flexible base material to
which a copper foil is laminated by means of an adhesive. The finished circuit
is frequently provided with a covercoat bonded to the copper side by means of
an adhesive.
2.
Double-Sided Flexible Circuits
As
the name suggests, the circuit consists of a thin and flexible base material
with copper foil laminated to each side. The outer sides of the finished
circuits are frequently provided with covercoats bonded to the outer sides
(copper).
3.
Multilayer Flexible Circuits
A
multilayer flexible circuit consists of a number of thin and flexible base
laminates and copper foils laminated together by means of adhesive, in very
much the same way as rigid multilayer boards. Also it is common practice to
bond covercoats to the outer sides (copper).
4.
Flex-Rigid Circuits
A
flex-rigid circuit is a combination of rigid boards and flexible circuits, the
latter creating flexible interconnects between the rigid boards to which they
are laminated by means of bond plies.
5.
Flexible Circuits with Rigid Areas
In
some cases, the flexible circuit must support a number of relatively heavy
components or even a connector part. Therefore it is necessary to reinforce
such an area. This is accomplished by bonding a stiffener to that area. The
stiffener can be an extra layer of not too thin polyimide, or it can be a
glass/epoxy laminate.
