Flex Circuit Board: How Rigid-Flex Circuits Enhance an Electronic Device’s Performance

You often read about the Internet of Things or IoT, Industry 4.0, API, and automation on various websites as well as on news. Almost everything you saw in movies or read in sci-fi books is now present, though flying cars or Star Trek will still need some time to arrive. Flex and rigid-flex PCBs are currently in demand and this trend will continue to exist in the future too. After all, PCBs are an integral part of all those electronic gadgets that you use all the time. Now, the popularity of flex and rigid-flex circuits increase naturally because advanced technology needs them. Many products connected to IoT have to be small, light, and cost-effective. In that respect, immaculately designed flex and rigid-flex circuits support these devices. Here you will learn how PCBs improve the performance or aesthetics of electronic devices.

Reduced weight: When you use a flex circuit board designed by cplfpc, you can reduce the weight of a device significantly that you wish to create. It is possible because these PCBs don’t have reinforcements with a characteristically higher density than unfilled polymers.

Decreasing assembly time: Upon using a flex circuit board from Capel Technology Co. Ltd, you won’t require connectors or cables. The seamless integration of multiple rigid PCBs into one rigid-flex PCB saves time and increases reliability.

Cost of purchasing: Indeed, the price of a rigid-flex PCB can be higher than multiple rigid PCBs. Then again, you won’t have to spend money on connectors or cables to establish connections between them. Furthermore, the increased system reliability that you get by avoiding connectors and cables provides a benefit that outruns the expenses.

Dynamic flexing: When it comes to dynamic flexing applications, a very thin polyimide, and an equally thin copper foil comes together to become the ideal connector. With a bend-and-stay application, you can use thicker boards or ones with several layers.

Dissipation of heat: Heat dissipation is generally better on the flat copper tracks that you find on flexible circuits compared to around-wire surrounded by insulation materials. It makes flexible circuits the best choice in areas where heat resistance is crucial.

Radius of bending: Rigid-flex circuits are highly bendable, but it depends on the number of layers to bend, the thickness of the copper used, and the overall thickness. Single-sided flex circuits can bend three to six times the circuit thickness. Similarly, double-sided flex circuits can bend seven to ten times the circuit thickness. With multi-layer flex circuits, the number ranges between ten and fifteen times.

Materials used: The most common raw material used in the construction of rigid-flex circuits is polyimide. However, you may use other materials such as polyester, polyethene naphtha late, liquid crystal polymer, and more. Among all these materials manufacturers generally choose polyimide for projects where reliability is the top priority.

Increased possibilities

Designers always find that their possibilities or chances of being innovative increases when they use flexible circuits. The company mentioned earlier in this topic has been manufacturing top-notch flex circuits as well as flex-rigid PCBs for the last ten years. The organization focuses on research, development, and designing various products for use in multiple industries.
