Single-Sided Flexible Printed Circuit (FPC) – Single Layer Flexible PCB for Bluetooth Headsets and More
(Printed Circuit Boards are custom-made products, the picture and parameters shown are just for reference)
In the ever-evolving world of electronics, flexibility and reliability are key to designing compact and efficient devices. The Single-Sided Flexible Printed Circuit (FPC) is a cutting-edge solution designed for applications requiring high flexibility, reduced weight, and space-saving designs. Built on SF201 adhesiveless polyimide at 0.15mm thick, this single-layer FPC is ideal for Bluetooth headsets, mobile devices, and other compact electronic applications.
Designed to operate at lower temperatures and with improved dimensional stability, RF-60TC is perfect for miniaturized antennas, high-power amplifiers, and satellite applications. Its low coefficient of thermal expansion (CTE) and reliable plated through holes (PTH) make it ideal for multilayer PCB designs.
Key Features of Single-Sided FPC
1.Excellent Flexibility: The FPC can be freely bent, wound, and folded, making it ideal for applications where space and flexibility are critical.
2.Reduced Volume and Weight: By using FPC, the overall volume and weight of electronic products can be significantly reduced, enabling the development of smaller and lighter devices.
3.High Reliability: The FPC offers increased reliability and consistency in assembly, ensuring stable performance in demanding environments.
4.Controllable Electrical Parameters: The design allows for precise control of electrical parameters, ensuring optimal performance for specific applications.
5.Low Cost: The FPC is a cost-effective solution, offering excellent performance without the high costs associated with traditional rigid PCBs.
6.No Minimum Order Quantity (MOQ): We offer low-cost samples and no MOQ, making it easier for you to test and integrate the FPC into your designs.
7.Material Optionality: The FPC can be customized with different materials to meet specific application requirements.
