Flexible board classification
Flexible board is usually classified according to the number and structure of conductors as follows:

Single-sided Flexible Board

A single-sided flexible board has only one layer of conductor, the surface with or without a covering layer. The insulating substrates used vary with the application of the products. Generally used insulation materials are polyester, polyimide, PTFE, flexible epoxy-glass cloth, etc.

One-sided flexible board can be further divided into the following four categories:

1) Flexible PCB without covering layer

The conductors of this flexible PCB are on the insulating base material, and there is no covering layer on the conductor surface. Like the usual one-sided rigid PCB. This kind of product is the cheapest one, usually used in non-critical and environmentally friendly applications. Its interconnection is realized by soldering, fusion welding or pressure welding. It was often used in early telephones.

2) Flexible PCB with covering layer

Compared with the former type, this kind of board only has an additional layer of cover on the conductor surface. When covering, the pad should be exposed. It is one of the most widely used in a single-sided flexible PCB and widely used in automotive and electronic instruments.


Double-sided flexible PCB

Double-sided flexible PCB has two conductors. This kind of double-sided flexible PCB has the same application and advantages as single-sided flexible PCB. Its main advantage is to increase the wiring density per unit area. It can be divided into:
a. without PTH hole and no covering layer;
b. without PTH and with covering layer;
c. with PTH and no covering layer;
d. with PTH and covering layer. 

Double-sided Flexible PCB without Covering Layer is Less Used
 

Multilayer Flexible PCB

Flexible multilayer PCB, like rigid multilayer PCB, can be made into multilayer flexible PCB by using multilayer lamination technology. The simplest multi-layer flexible PCB is a three-layer flexible PCB formed by two copper shielding layers on both sides of a single PCB. The three-layer flexible PCB is equivalent to coaxial or shielded conductors in electrical characteristics. The most commonly used multi-layer flexible PCB structure is a four-layer structure, which implements interlayer interconnection with PTH holes. The middle two layers are generally the power layer and the ground layer.

Multilayer flexible PCB has the advantage of light weight and excellent electrical properties, such as low dielectric constant. Multilayer flexible PCB board made of polyimide film is about 1/3 lighter than rigid epoxy glass cloth multilayer PCB board, but it loses the excellent flexibility of one-sided and two-sided flexible PCB. Most of these products do not require flexibility.
