What Makes Sierra’s Flex PCBs Unique

Flex printed circuit boards can offer many advantages over rigid PCBs. They offer excellent tensile strength, extreme bendability, and fewer design and manufacturing constraints. For cutting-edge products such as wearables or miniature medical devices, flex PCBs are literally and figuratively a natural fit. They allow for lightweight designs that consume less space due to the replacement of traditional wiring harnesses and cables.

What makes Sierra Circuits’ flex PCBs and processes unique
Sierra Circuits is an experienced, reliable manufacturer of flex PCBs. What is special about how we approach flex? For starters, we serve as a single point of contact throughout the entire process of quoting, designing, ordering, manufacturing, and delivery. Plus, our flex PCB solutions have several key differentiators that make them suited for several use cases:

  • We produce only the highest quality boards, with polyimide film and thin copper foils on trace and space as small as 50 microns. Even with this level of precision, we can deliver them to you on deadlines as short as 24 or 48 hours after ordering. Our process has been honed over nearly 30 years to provide as a one-stop shop that meets all your PCB requirements, from in-house fabrication to turnkey services.
  • Our top-of-the-line flex PCBs have already proven themselves in applications in a wide range of industries and devices. Our boards have been used in handheld as well as implantable medical equipment. They can also be implemented in aerospace and automotive applications or in consumer electronics such as laptops.
  • In addition to flex PCBs, we also make rigid-flex PCBs and High Density Interconnect (HDI) flex PCBs. Rigid-flex PCBs bridge traditional and flex designs and are often used to connect several rigid flex boards using flexible circuits. HDI for flex PCBs may be needed to free up more space for other features on the board and make the most of the small package size.

Something else that sets Sierra apart is the level of assistance we offer during the design process. We have drawn up many guides for ensuring the best possible results for your prospective flex PCB, rigid-flex PCB, or HDI flex PCB. We have also published some of these tips on this blog, such as how you can get optimal flex stackups and use the best possible materials.

When manufacturing flex PCBs, we use only state-of-the-art machinery for the completion of crucial tasks such as laser drilling and direct imaging. All of our design, manufacturing, and assembly is done in a spacious, high-tech facility in Sunnyvale, California. From here, we offer an easy-to-reach point of contact along with quick turnaround times for the leading tech giants in the area. Sierra is also ISO 9001:2008, ISO 13485:2003, MIL-P-55110, and RoHS certified.
