FPC is made of polyimide material and etched copper conductors. ... Single-sided flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film.
A flexible printed circuit consists of a metallic layer of traces, usually copper, bonded to a dielectric layer, usually polyimide.

Double-sided flex circuits are flex circuits having two conductor layers.

The Flexibility and Reliability of FPCB

 

At present, four kinds of flexible circuit boards are prevalent: single-layer board FPCB, double-layer FPCB, multi-layer FPCB and rigid-flexible FPCB. The single-layer FPCB has a layer of chemically etched conductive pattern, and the conductive pattern layer on the surface of the flexible insulating substrate is a rolled copper foil. The insulating substrates used of the flexible assembly may be Kapton, PET, Nomex, and PVC.

 

The double-layer FPCB has a conductive pattern formed by etching on both sides of the base film. The metallized holes connect the two sides of the insulating material to form a conductive path to meet the flexural design and functions. The covering film protects the single-layer and double-layer wires and indicates where the components are placed.

 

The multi-layer FPCB is formed by laminating three or more layers of single-layer FPCBs or double-layer Fpcbs, and forming metallized holes by drilling and electroplating to form conductive path between different layers. In this way, there is no need to adopt complex welding procedures. Although the number of conductive layers designed for this FPCB can be infinite, the interaction of the assembly size, the number of layers, and the flexibility should be taken into account in designing the layout in order to ensure the convenience of assembly.

 

Conventional rigid-flexible FPCB is made up of rigid and flexible substrates that are selectively laminated together. The structure is tight, and the metallized holes form an electrically conductive connection. Given reliability and price factors, manufacturers should try to keep as few layers as possible.

 

The FPCB industry is in the process of small scale but rapid development. PTF is a highly efficient, low-cost process for producing circuit boards. This process selectively prints conductive polymer inks on cheap flexible substrates. Its representative flexible substrate is PTE. PTF conductors include silk-printed metal fillers or carbon powder fillers. The PTF itself is clean and uses lead-free SMT adhesives without etching.

The Applications of FPCB

 

Due to the rapid development of the times, people have more and more demand for electronic information, and the FPCB play an essential role in this case.

 

(1) Mobile phone

Emphasize the light weight and thinness of FPCB, it can effectively save the product volume, and easily make the battery, microphone, and key connect together.

(2) Computer and LCD screen

Take advantage of the integrated circuit configuration of FPCB, as well as the thickness, convert the digital signals into pictures and present them through the LCD screen.

(3) CD Walkman

Emphasize the three-dimensional assembly characteristics and thinness of FPCB, transform the huge CD into a companion.

(4) Disk drive

Whether it's a hard disk or a floppy disk, it relies heavily on the high softness and the ultra-thin thickness of 0.1mm of the FPC to complete fast data reading.
