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.
