Flex and Flex Rigid PCBs
Flexible PCBs: Flexibility Redefined, Innovation Unleashed
​
At Hi Spec, we excel in the production of flexible PCBs, offering a versatile range of options to suit various applications. From single-layer flex circuits to complex multilayer flex-rigid designs, we specialize in creating flexible PCB solutions that push the boundaries of innovation and flexibility.
​
What Are Flexible PCBs?
Flexible PCBs, also known as flex circuits, are printed circuit boards made from flexible materials that allow them to bend, twist, and conform to fit into tight spaces or irregular shapes. These flexible materials typically include polyimide or polyester substrates, which offer excellent flexibility and durability while maintaining electrical performance.
​
These PCBs are commonly used in industries such as aerospace, automotive, medical devices, and consumer electronics, where space constraints and complex designs are common. They offer advantages such as reduced size and weight, improved reliability, and enhanced durability.
A 4-layer flex-rigid PCB stack-up combines flexibility and rigidity into one board.
It includes solder mask layers for protection, base copper layers for conductivity, FR4 substrate for structure, prepreg layers for insulation, and a polyimide core for flexibility.
This stack-up provides the versatility of a flexible PCB with the stability of a rigid PCB, making it ideal for space-constrained and durable applications.

-
Bendability and Flexibility: Flexible PCBs are designed to bend and flex without breaking, allowing them to conform to the shape of the device or system they're installed in. This flexibility makes them ideal for applications where space constraints or movement are present.
-
Lightweight and Compact: The use of flexible materials in PCB construction results in lightweight and compact designs, making flexible PCBs well-suited for portable devices, wearable electronics, and other applications where size and weight are critical.
-
High-Density Interconnections: Despite their thin and flexible nature, flexible PCBs can accommodate high-density interconnections, allowing for complex circuitry and miniaturization of electronic devices.
-
Reliability and Durability: Flexible PCBs offer excellent reliability and durability, with the ability to withstand bending, vibration, and thermal cycling without compromising performance.
-
Design Versatility: Flexible PCBs offer design versatility, allowing for unique shapes, 3D configurations, and integration of components directly onto the flexible substrate for simplified assembly and reduced manufacturing costs.
