Product Benefits
Semi-Flex PCBs are a cost-efficient solution to optimize a great number of projects. Made from FR4 material, which is the most affordable base material for PCBs, it can reduce space, weight, and improve the reliability of the final product as connectors are considered a reliability risk in many applications.

Cost-Effective
The FR4 Semi-Flex replaces 2 or more PCBs, simplifies the assembly process, eliminates connectors, and is cheaper than the Rigid-Flex solution.
Time Saving
FR4 Semi-Flex reduces the time needed for design, procurement, and assembly.
Reliability and Durability
Fewer solder joints and fewer connectors.
Size Optimization
Using FR4 Semi-Flex optimizes the PCB size, saving the space of the connectors on both “rigid” parts.

A semi-flex PCB is characterized by its ability to bend or flex to a certain degree while maintaining its structural integrity. This type of PCB is often used to save space in the final product and avoid the use of connectors between two circuit boards. Semi-flex PCBs are manufactured using a combination of traditional PCB fabrication processes, such as photolithography, etching, and drilling, as well as specialized techniques for handling the flexible substrate. The final product is a PCB that can bend or flex to a certain degree while maintaining its electrical performance and durability.

Base Material: The base material used in a semi-flex PCB is FR4.
Flexible Area: The flexibility is created either by Z-milling the flex area in the FR4 or by sequential stack-up. The thin FR4 area allows a certain degree of static flexibility, with less than 10 bending cycles.
Lines and Spaces: There are restrictions to minimum trace and spacing widths in the semi-flexible area to ensure trace strength and reliability.
Layer Count: There are no restrictions to the total layer count in an FR4 Semi-Flex PCB, but the flexible part can only hold a maximum of 2 layers.
Surface Finish: All common surface finishes are supported on FR4 Semi-Flex
Solder Mask: The solder mask in the flexible area needs to be either a flexible solder mask or a PI coverlay. Other parts of the circuit board can have a standard liquid solder mask.

FR4 Semi-Flex is a cheaper solution than Rigid-Flex. It should not be used for applications exposed to shock and vibrations. FR4 Semi-Flex creates reliable 3D connectivity opportunities by replacing board-to-board connectors, which leads to space and weight reductions. It is widely used in Instrumentation, Metering, Sensor technology, and Industrial controls.
