Single-Sided FPC
Single-sided FPC is one of the most basic and simple structure. In a single-sided FPC, the circuit is only present on the substrate on one side, while the other side is usually bare or covered with a protective layer. Single-sided FPC is suitable for simple circuit routing needs, with a lower cost and a simpler manufacturing process.
Double-Sided FPC
The double-sided FPC structure has circuits on both sides. More complex circuit layouts and connections are achieved by adding circuits on both sides. Double-sided FPCs typically have higher densities and more connectivity options, making them suitable for more complex electronic devices such as mobile phones, tablets, etc. Since double-sided FPCBs can accommodate more circuit components in the same space, more functions and higher performance can be realized.
Flex-Rigid PCB
Flex-rigid PCBs combine the characteristics of flexible FPCs and rigid PCBs. They typically consist of flexible sections and rigid sections interconnected by reliable connection methods. Flexible sections are often used for parts requiring bending and folding, while rigid sections are used for support and stability. This structure is suitable for applications that require both flexibility and rigidity, such as foldable smartphones, camera modules, etc.
Multilayers FPC
Multilayer FPC structures consist of multiple layers stacked together. These layers are interconnected through inner layer connections and alternate between flexible substrates. Multilayer FPCs are typically used in applications that require higher signal density and complex layouts, such as computer motherboards, industrial control systems, etc. Because multilayer FPCs can accommodate more circuit layers in a smaller space, they enable designs with more complex functions and higher performance.
Split & Dual Access (Bare Back)
Split FPC structures allow the creation of multiple independent areas on the FPC, each of which can be accessed and connected to circuits. This structure is used in applications that require the separation of different functions or modules to improve system flexibility and maintainability. Split FPCs are often combined with dual access (bare back), allowing direct access to circuits on the back of the FPC, simplifying the connection and maintenance processes.
