Flexible Circuit Boards

Flexible circuit boards are your go-to-choice when you need PCBs to offer you 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 it fits the circuitry. With a malleable base material, flexible printed circuit boards are a popular choice as they offer enhanced capabilities to suit today’s complex and miniature appliances. With the design freedom that they offer, flexible printed circuit boards result in lightweight and durable products. From wearable technology to medical equipment, its use is ubiquitous as it helps retain the precision of a regular PCB while offering unlimited freedom as far as the packaging geometry is concerned.

As a leading flexible printed circuit boards manufacturer, we are fully equipped to offer you high-quality flexible printed circuit boards to meet your bespoke requirements. Avail of the boundless freedom of packing geometry offered by flexible PCB!

With consistently growing demand of flexible circuit boards, At Technotronix we can take up any challenges from design, manufacturing, prototyping, through final production to deliver the quality production at competitive price!

Benefits of flexible printed circuit boards

Flexible circuit boards come with a wide range of benefits including but not limited to:

  • 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.
  • Flexible printed circuit boards are known for their high tensile strength and work well in harsh environments.
  • With their low mass and high ductility, flexible PCBs work well in environments 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.
  • Flexible PCB boards are known for their reliability since they need fewer interconnects, connectors and solder joints.
  • The fact that flexible printed circuits are compatible with any type of components and connectors adds to their popularity.
  • With reduced materials and packaging demands, reduced assembly errors and reduced parts replacement costs, it results in sizeable cost savings.

Flexible Circuit Boards FAQs

Flexible circuit boards are a combination of printed circuits with components which are positioned on a flexible substrate. They are also known as flexible printed circuit boards, flex PCBs, flexible printed circuits and more!

Using flex 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 circuits weigh far less than their rigid counterparts. While the thinnest rigid board could weigh 500 microns, a typical flex 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 quote as soon as possible!

As a leading flexible printed circuit boards manufacturer, we provide single sided flexible circuit boards, double sided flex PCBs, multilayer flexible printed circuit boards, rigid-flex PCBs, HDI flexible circuit boards & 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.

We cater to board thickness between 0.1mm - 0.8mm.

On the face of it they may seem more expensive, but given the cost savings that they offer in terms of reduced materials and packaging demands, reduced assembly errors and reduced parts replacement costs, there are sizeable cost savings.
