FPC flexible plate development history and what reforms have been made to achieve continuous innovation?

FPC flexible plate development history and what reforms have been taken to achieve continuous innovation FPC the future needs to go from four aspects.

Mainly in: thickness. The thickness of FPC must be more flexible and must be thinner.
Folding resistance. Bending is the inherent characteristic of FPC. The FPC resistance of the future must be stronger and must be more than 10 thousand times, which requires better substrates.
Price。 At this stage, the price of FPC is much higher than that of PCB. If the price of FPC is down, the market will be wider.
Process level. In order to meet various requirements, the FPC process must be upgraded, and the minimum aperture and minimum linewidth / line spacing must meet higher requirements.
The earliest concept of soft plate was in 1904, when Edison Te came out. He made lines on linen paper to transmit current. So he put it on paper
Print the pattern and make the circuit by metal replacement. This is the earliest concept of soft plate, but in the past many years, this technology has not been much.
It is applied to production and is used to make lines. It was not until human beings began to march into space that the technology was reapplied to the production of circuit boards.
But it is limited to some scientific research institutions.
Later, the Japanese began to develop and produce FPC soft plate technology, and 1916 first proposed that metal copper foil be selectively etched. In 1920
People use photosensitive materials to expose, develop, and etch lines. This technology has been used in actual production, and this technology is later used in various kinds.
The circuit board is on top. At that time, many printing technologies and assembly technologies were put forward by the producers. However, due to the limited raw materials at that time, the production was affected.
Relatively large restrictions, rubber substrate or soft plate production at that time is the main material. After 1940s, the production of soft boards is really widely used.
In the production and manufacture of circuit boards, circuit boards are used to replace the copper wires used before in electronic products, so that the efficiency of electronic products is accelerated.
The speed of repeated production and manufacture has been greatly accelerated.
It is in electronic products that circuit boards and FPC soft boards are widely used to reduce the volume and weight of electronic products. We all know the first one.
How huge the computer is, the size of a room is large. It is the application of circuit board that makes the product constantly reduce the volume and weight.
The main demand characteristics of the electronic products at that time.
After 60s, we used a large number of tape recorders and DVD machines to make the electronic products mass production and cost reduction.
These products can be widely popularized and popularized. At this time, almost all the electronic products used circuit board technology to transmit current, and the soft board was later.
The gradual increase of product demand characteristics has been widely applied to product connection and special demand circuit production.
Modern electronic products are full of application of circuit boards. With the continuous miniaturization, thinning, three-dimensional space and appearance, the electronic products are more and more strange.
The development of soft plate has been widely used. Soft plate is one of the main reasons to promote this phenomenon in bending, bending and so on.
A large number of applications of soft boards enable electronic products to produce millimeter to calculate the thickness of products. A small watch can achieve a large number of functions to be condensed.
Together, these are the advantages brought by the development of soft board. Now we are not only pursuing the external functions of the main products, but also the development of intelligent electronic products.
It is a breakthrough in the development of soft plate. At present, soft plate is not an alternative to micro electrical transmission and current stability transmission. These technologies are intelligent products.
The main appeal. After all these years, the development of soft panels is not only about the ability of conducting and connecting in electronic products, but also in soft parts.
Reinforcement can play the role of supporting components. The soft board has always appeared with circuit boards in pairs. Now, with the gradual development of FPC soft boards,
And perfect, soft board can already appear in electronic products independently. Like micro motors, they are made of flexible boards independently, but the application of PCB is very important.
There is still no way to leave the soft board. On this basis, the hard and soft joint board has appeared. This technology has been widely used in various products.
Because of the high cost of such technology production, the hard and soft panels appear in some kinds of products with higher requirements.
