Flexible PCBs

What is a flexible PCB

So what is a flexible PCB, and how do we know whether it’s right for you and your next project?  When it comes to flexible PCBs, also known as ‘flex PCBs’ or ‘flex circuits’, the main differentiating point is that the electronic devices are mounted onto flexible plastic substrates.

Instead of building a device in which the components must comply to the size of the circuit board, flex PCBs are instead designed to fit the device or product. Flex PCBs are usually thin, lightweight and can work exceptionally well in small spaces and in contoured shapes, which can be a challenge for other printed circuit boards.

When it comes to deciding on the perfect PCB for your next product, there are several options available, from single- and double-sided, to multilayer and flex PCBs. Finding the right option that works for you and your latest innovation is important.

What are the benefits of flexible PCB’s

There are several advantages of a flex PCB that are worth considering when thinking of the best foot forward for your all-important product:

  1. Space Race: The nature and design of flex PCBs mean they do not use as much space, and additionally weigh less than an ordinary circuit board
  2. Bend and Snap: As the name would suggest, flex PCBs also have inherent flexibility allowing for tighter bend capabilities for your product
  3. Feeling The Heat: Flex PCBs, due to their substrates such as polyimide, dissipate heat better than most circuit board materials and are able to withstand extreme temperatures
  4. Compatibility Test: Flexible printed circuit boards are compatible with a wide range of components or connectors, many being smaller or less expensive connectors

On top of the above benefits, flex PCBs also use less material, less packaging and the costs for replacements are lower, which can never be a bad thing! Flex PCBs offer a plethora of possibilities for different products and designs combining the best qualities of connectors, printed circuit boards, wires and cable, all in one interconnect.

Ian - MES

First time user of ABL and placed an order for a 4 layer board with 2oz copper on all layers. Order received in 5 days and the quality of the board was excellent. Probably the best quality of board that I have received from using countless suppliers. Would definitely recommend ABL for PCB manufacture and will be using them again for my next PCB request.


Very nice company to work with as they are always happy to help solve any of my problems fast and good quality work. They are my number one PCB supplier.


Excellent service, fast and efficient with excellent help during the development of the circuit design. Great pricing structure and very professional.
