Flexible Circuit Boards

Flexible printed circuit boards (Flex PCBs) are the ideal choice when you require PCBs that can be shaped into various configurations, offering unparalleled design flexibility. Named for their ability to conform to the shape of the electronic device rather than vice versa, Flex PCBs utilize a pliable base material that caters to the complexities of modern, compact appliances. This flexibility not only allows for lightweight and durable products but also enhances their suitability for applications ranging from wearable technology to medical equipment.

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.

Application of flexible PCB manufacturing

In situations where reliability and adaptability are at a premium, flexible PCB manufacturing is increasingly preferred. Little surprise then that they find a wide range of application in a wide variety of industries such as:

Medical devices

Communication systems

Consumer electronics

Automotive

Transportation

Construction

Flexible Circuit Boards FAQs

1. What are flexible circuit boards?

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!

2. What are the advantages of using flexible printed circuit boards?

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.

3. How much do flex circuit boards weigh?

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.

4. Are there any design rules for placing parts on the flex printed boards?

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

5. Why is a stiffener used in Flex PCBs?

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.

6. Do you cater to multi-layered flex boards?

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!

7. What type of flexible circuit boards do you provide?

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!

8. Which type of material you are using in flexible PCB manufacturing?

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

9. What kind of surface finishes do you offer for custom flexible circuit boards?

We cater to the following surface finishes:
HASL - Hot air solder leveling
Lead - free HASL - RoHS
ENIG - RoHS
