Flex your potential.

Flexible PCBs are lightweight, easy to install, durable, and compact. The wide range of motion makes it ideal for nearly all applications. Use flexible circuits in “bend to install” applications or dynamic applications, where the circuits are continuously in motion. Flexible circuits are also advantageous for the design packages where space is a primary concern.

We offer three types of flex PCBs:

• Flex
• Rigid-flex
• HDI flex

Physical advantages for flex:

More flexibility, as the name suggests
Improved resistance to vibrations and movement; lower mass/weight
Small package size
Allows the board to bend to its desired applicable shape
Allows for more compact devices
High tensile strength—can be significantly warped/deformed without breakage
High bendiness—up to 360 degrees
Easier to prepare for harsh environments
The use of flexible flat cables (FCC), which can bend without being damaged, and takes up less space than traditional wires

Manufacturing & assembly advantages:

Increase in design freedom
Installation flexibility
Increased reliability and durability
Improved heat dissipation
Improved airflow
