A Flex Circuit or Flex PCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application.
FPCBs are used widely in everyday technology and electronics in addition to high-end, complex completed components. Two of the most prominent examples of flexible circuit usage is in modern portable electronics, devices, hard disk drives and desktop printers.
Flexible circuits are also used extensively in other applications and industries including:
In transportation they are extensively used due to their improved resistance to vibrations and movement.

Heavy Copper Flex PCB

San Francisco Circuits can provide heavy copper flex circuits that can also be coupled with flexible thin copper layers designed to handle heavier power currents. We can build the heavy copper boards with flex portions for lower voltage additions and applications.
Whether you're looking for a double sided flex circuit or complex multi layer flexible PCBs from your flex PCB manufacturer, we can provide you with the guidance, expertise and capabilities to bring your concept to reality. Multi-layer flex boards are being used more often in electronic applications for higher speed performance but at a loss of flexibility. Single-sided or double-sided multi layer flex PCBs can be designed in unique and complex layouts, with a much greater possibility of combinations compared to FR4 board design. Just as multi-layer FR4 boards, the multi layer FPCBs can be designed using blind and buried vias as well as plated through holes (PTH).
The primary benefits of flexible circuits compared to traditional cabling and rigid boards include the following benefits listed below. Read our full list of the advantages of Flex PCBs.
Flex boards benefits include:
Flex PCB disadvantages also exist, including the following:
To ensure the highest quality of your flexible circuit board, we also offer thermal cycling and shock testing to ensure proper usage in the desired environment. PCB burn in testing is available for all SFC-provided boards. We can also provide PCB assembly for all circuit board types.
