FPC flexible boards have a wide range of applications in the modern electronics industry, but their through-flow capability is often overlooked. High pass and stable flow capability is a key characteristic of a high-quality FPC flexible board product, which determines the durability and reliability of FPC flexible board in electronic devices.
FPC flex board is becoming more and more important in electronic devices, and it is necessary to not only care about the reliability and stability of FPC flex board, but also consider the maximum current it can withstand. If the maximum current is not reached, the FPC will be unstable, which will affect the performance of the entire electronic device. Therefore, the stronger the current capability of the FPC, the wider the application scenarios it can achieve. This has also become one of the important symbols of high-quality FPC flexible board products.
Thickness of the copper layer: The copper layer is the main carrier of the current carried by the FPC flexible board. The thicker copper play can withstand a higher amount of current and can reduce the impact of the increased temperature of the FPC flex board on the overall electronic device.
Conductor width and distance: The width of the conductor and the distance from other conductors affect the magnitude of the current flow as it flows to the terminal. Relatively wide conductors and close distances can improve through-flow capacity.
The strength of the bond between the copper foil and the substrateIf the adhesive strength is insufficient, local hot spots will occur, which will affect the flow efficiency and have a negative impact on the service life of FPC.
Choose high-quality copper pour: High-quality copper pour materials typically have higher electrical conductivity, greater thickness, and higher heat resistance. These features can improve the current flow capacity of FPC flex boards and extend their service life.
Design reasonable conductor widths and distances: Reasonable conductor design can maximize the flow capacity of FPC flexible board. The design should take into account the influence of the load of the circuit and the working environment, and carry out detailed design.
Optimize bond strength: In order to avoid the problem of local hot spots, attention should be paid to the bond strength between the copper foil and the substrate. Scientific selection and application of adhesives to make full use of chemicals such as adhesive strength enhancers.
Reasonable heat dissipation mode: In order to ensure that the FPC flexible board does not overheat under long-term high-current load, a reasonable heat dissipation mode should be adopted. The heat dissipation area and its heat dissipation efficiency are the key factors affecting the heat dissipation mode.
The flow capacity of FPC flexible board can be improved by selecting appropriate copper deposits, reasonable conductor design, optimizing adhesive strength, and adopting reasonable heat dissipation modes. This will enable FPC to have higher performance and stability in various practical application scenarios.
