Flexible PCBs

At Pure PCB’s, our flexible capability is a cornerstone of our PCB capabilities. We provide our customers with reliable, high-quality solutions that eliminate the need for connectors and cables within any product. Get in touch with a member of our friendly sales team today for more information on our flex capabilities.

What is a Flexible PCB?

Also referred to as flex circuits, flexible PCBs are able to twist and fold to fit the shape of your board designs – a flexible PCB,  allows the circuitry to be designed to fit the electronic device or product, as opposed to building the device to conform to a rigid circuit board.

The board’s bending capability can be altered to fit your requirements and needs – we also offer multilayer PCBs and rigid flex solutions for customers looking for a more rigid structure.

Types of flexible PCBs available

Here at Pure PCB, we have a range of surface finishes available for your flexible circuit boards:

  • ENIG
  • Lead free HASL
  • ASIG
  • ISIG
  • Immersion Tin
  • Immersion Silver.

The applicable quality standard of our flexi PCBs is also PC 6013 Class 3. We also have a selection of available stiffener materials including:

  • Thermal adhesive
  • Standard FR4
  • Polymide
  • Aluminium  

Advantages of flexible PCBs

Flexible circuit boards offer many advantages due to their bend and flex properties:

  • Wiring Solutions – investing in flexible PCBs allows you to fit your circuit board to your product by allowing you to twist the circuit board into areas that a single sided, rigid circuit cannot. The lack of rigidity of our PCBs offers improved wiring solutions.
  • Lighter products – a product with a flex circuit board is likely to be lighter as the material used for flex circuit boards is not as heavy as the materials used for a rigid counterpart.
  • High Temperature – most of our flex circuit boards are built with polyimide, a material that dissipates heat better than most. Therefore, flexible boards can be added to hotter areas that would cause damage to rigid boards.
  • Durability – alongside the high temperature resistance, flex circuits are designed to withstand chemical corrosion and radiation & UV exposure. Products with a flexible printed circuit board tend to be highly durable.
  • Miniaturisation – flexible boards contain a lower number of device interconnects meaning miniaturisation is a much more viable option for a product design during the PCB fabrication.
