What are the advantages of FPC flexible circuit board?

FPC flexible circuit board / FPC flexible circuit board (Flexible Printed Circuit Board), as the name suggests, has the function of inflection and use, and can be made into a three-dimensional space. Therefore, in theory, only one FPC flexible circuit board/FPC flexible board can complete the overall wiring work in one machine. Since the use of FPC flexible circuit board/FPC flexible board can omit many connectors or wires, the wiring volume can be greatly reduced, so the goal of miniaturization and light weight of electronic products can be achieved. In addition, many parts can be assembled on the FPC flexible circuit board/FPC flexible board, and can be stored in the gaps in the machine, so the well-designed circuit does not need any welding and adjustment work after being installed in the chassis, which greatly reduces the cost. cost.

Since the FPC flexible circuit board/FPC flexible board has the ability to withstand the back and forth bending with a small radius, this characteristic is difficult to replace by ordinary wires. Therefore, recently, the use of FPC flexible circuit boards/FPC flexible boards on the print head has absolutely overwhelming the phenomenon of ordinary wires, and almost all the print heads on electronic calculators and personal computers have adopted FPC flexible circuit boards/FPC flexible boards. . And among the most recently developed circuit formation technologies, circuits with a width of 0.1mm and a pitch of 0.2mm can be regulated, especially for circuits that need to flow through most signals but do not need to flow a large current, the ground wire can be configured at the same time. and power cord.

Light and thin is a major feature of FPC flexible circuit board/FPC flexible board. Most RPCs have a thickness of 1.6 mm, and the most recently developed fiberglass RPCs have a thickness of 0.40.6 mm. In general, when a current of about 1A flows through a wire, the thickness of its insulating sheath should also have an outer diameter of 1mm. However, if the general performance FPC flexible circuit board/FPC soft board is used, if there is a substrate thickness of 25um, the overall thickness only needs to be 100-140um, which fully shows the advantages of FPC flexible circuit board/FPC soft board in thickness. In terms of weight, the weight of the plastic matrix and the fiberglass matrix is completely incomparable.

From the above points, it can be seen that in order to reduce the weight and volume of the product, we must rely on FPC.

In addition, FPC flexible circuit board/FPC flexible board has the advantage of improving product reliability. Even with fewer solder joints, there are fewer connectors, greatly reducing the chance of failure. In addition, compared with the traditional substrates that are wired one by one, the assembly man-hours can be greatly reduced, and many operating errors can be eliminated, so the on-line repair work can be greatly reduced, and the production cost can be greatly reduced.
