Flexible Circuit Boards

Flexible circuit boards are your go-to-choice when you need PCBs that offer the freedom of shaping them into different configurations. In fact, Flex PCBs derive their name from their capability to ensure that the circuitry can be designed to fit the electronic device instead of building the device in a manner in which fits the circuitry. With a malleable base material, it is a popular choice as they offer enhanced capabilities to suit today’s complex and miniature appliances. With the design freedom flexible printed circuit boards result in lightweight and durable products. From wearable technology to medical equipment, its use is ubiquitous as it helps to retain the precision of a regular PCB while offering unlimited freedom as far as the packaging geometry is concerned.

As one of the leading flexible printed circuit board manufacturers, we are fully equipped to offer you high-quality custom flexible PCBs to meet your bespoke requirements.

With consistently growing demand, we can take up any challenges from design, manufacturing, prototyping, through final production to deliver quality production at competitive cost!

Benefits of flexible printed circuit boards

  • Flex PCB has small package size lends itself seamlessly to the current trend of miniaturization that they are lighter than normal boards add to their efficacy.
  • They are known for their high tensile strength and work well in harsh environments.
  • With low mass and high ductility features, flexible PCBs work well in an environment where there is a lot of vibration. The stress and impact on the solder joints on a flex PCB is far lower than that faced by rigid PCBs.
  • Custom flexible circuit boards are also known for their high current carrying capacity.
  • They are known for their reliability since they need fewer interconnects, connectors and solder joints.
  • They are compatible with any type of components and connectors add to their popularity.
  • With reduced materials and packaging demands, reduced assembly errors and reduced parts replacement results in sizeable cost savings.

Flexible circuit boards are a combination of printed circuits with components which are positioned on a flexible substrate.

Using flex circuit boards eliminates or completely decreases cable cost, it is known to reduce assembly time, and produces a lighter end-product. They are also known for their high tensile strength and reliability.

Flex circuit boards weigh far less than their rigid counterparts. While the thinnest rigid board could weigh 500 microns, a typical flex board may be only 100 microns.

As a thumb rule, it is recommended to place parts where the flex has a stiffener!

A stiffener serves many functions:
  • To strengthen areas of the board
  • To support PCB components
  • To keep certain areas flat and stable
  • To constrain the flexible parts to specified areas.

Absolutely! Do let us know your bespoke needs for any kind of multilayer flexible PCBs and we will get back to you with a quote as soon as possible!

We provide single sided, double sided, multilayer, rigid-flex PCBs, copper flexible circuit boards, and more!

We use copper, aluminum, electro deposited (ED) copper, Rolled Annealed (RA) copper, Constantan, Inconel, silver ink, and more based on custom specification.

We cater to the following surface finishes:
  • HASL - Hot air solder leveling
  • Lead - free HASL - RoHS
  • ENIG - RoHS
  • Immersion Tin - RoHS
  • OSP – RoHS

The build time could vary from 2 days to 5 weeks, depending on your requirements.

No, flexible circuit boards are not more expensive than rigid PCBs. Although it depends on your requirements.
