The earliest concept of FPC was proposed by Edison in 1904. He made a circuit on linen paper to transmit current. Therefore, he had an idea to print the graphics on paper, and then make circuit by metal replacement.

However, this technology has not been widely used in production for many years to make circuits. It was not until humans began to march into space that this technology was reapplied to the production of flexible printed circuit boards (FPCB). This is only in some scientific research institutions.

In 1920, people used photosensitive materials to expose, develop, and etch circuits. This technology has been used in actual production, and later it was used in the production of flexible printed circuit boards.

At that time, many printing and assembly technologies were proposed by manufacturers. However, due to the limited raw materials at that time, production was greatly restricted, and rubber substrates became the main material for production of flexible PCB at that time.

After the 1940s, the production of flexible PCB was truly used in large quantities in the production. Those boards were installed in electronic products to replace copper wire. It accelerated the production efficiency of electronic products, and greatly accelerated the speed of repeated production.

In 1963, DuPont of the United States invented polyimide (PI) film.

In 1965, PI film products were actually produced. They can be used as an insulating base film for FPC. They were first commercialized in the early 1970s, and were initially used mainly in military electronic products. As a result, the United States became the birthplace of the world's industrialized FPC.

It is the extensive use of flexible PCB that has greatly reduced the size and weight of electronic products. This demand of reducing size and weight has become the main one of electronic products at that time.

After the 1960s, tape recorders and video players at that time all applied this technology in large quantities, which enabled the mass production and reduced costs. These products were widely popularized and promoted.

At that time, almost all electronic products used circuit boards to transmit current, and FPC was widely used in product connections and circuit production for special needs as the requirements gradually increased.

Flexible PCB is used everywhere in modern electronic products. With the continuous miniaturization, thinness, three-dimensionality and various shapes of electronic products, the development of FPCB has grown fast. Bending of soft boards is one of the main reasons.

The large-scale application of soft boards allows electronic products to be produced with a thickness calculated in millimeters. For example, a small watch has a large number of functions. It owed to the development of flexible PCB.

Now, the development of smart electronic products is a breakthrough in the development of flexible PCB. Currently, flexible boards are still irreplaceable in micro-electric transmission and stable current transmission. The technology is crucial to smart products.

FPC is not only used for conducting electricity and connecting in electronic products, but also can play a supporting role by reinforcing the components in some places.

In the past, FPC has always been paired with PCB, but now with the gradual development and improvement, FPC can be used independently in electronic products. For example, micro motors are produced independently with FPC.
