What is flexible PCB prototype?

Flexible PCB Prototyping is the perfect choice for your electronic needs (commonly used in ATM keypads, printers, and wearable electronic products). It is widely used in various industries, including consumer electronics, medical, aerospace, communications, military, transportation, industrial and automotive. Flexible PCB Prototyping uses a naturally flexible substrate material with a high-temperature resistance to develop samples of an advanced electronic product in the electronics industry. Polyimide is used as the primary substrate material in manufacturing flexible PCBs. Flexible PCB Prototyping is an excellent inclusion to the technology and electronics industry as its lightweight and takes less space.

What is Flexible PCB?

Flexible PCB, also called flex circuits, or flex prints is an advanced PCB (Printed Circuited Board) that can be twisted, folded, or bent into any desirable shape. Flexible PCB was initially introduced in 1950 in the electronic industry for two primary reasons: For electronic products to be easily placed in irregular spaces, e.g., Keypads, and the utilization of flex in electronic products such as intelligent wrist-watches. It is expensive and has a wide range of applications in industrial electronics. Its flex designs consist of a transparent film of polyester or polyimide as the substrate Material with high heat and temperature resistance, making it suitable for soldering and assembling components.

What is Flexible Circuits?

At first, PCBs were manufactured using rigid substrate materials, which made PCBs available only in hard designs (card/board shaped). With the advancement in technological research, scientists considered it necessary to design PCBs that can be easily twisted or bent to be placed in inaccessible areas. Hence the concept of Flexible PCBs was developed.

Advantages of Flexible PCB Prototyping

The following are the advantages of Flexible PCB Prototyping over PCBs, making Flexible PCBs among the most critical technologies utilized in advanced electronic devices.

advantages of flexible PCB prototyping
  1. Small size
    This is the primary advantage of Flexible PCBs, which are adjusted and rolled into small spaces in certain situations. Flexible PCBs have negligible thicknesses like paper.
  2. Lightweight
    Flexible PCBs are light-weighted as they have no substrate core (cardboard) present. The weight of a flexible PCB is due to the presence of Surface Mount Devices (SMD) soldered to the PCB through surface mount technology.
  3. High Durability
    Flexible PCBs are durable if treated with care as flex circuits are designed by experts under precise and practical conditions. Flexible PCBs are also coated using formulated materials. This enhances its durability.
  4. High Temperature
    Flexible PCBs have high-temperature resistance. This makes Flexible PCBs widely used in the oil and gas industry, where rigid PCBs can easily melt out. This depends on the type of material used in the design of the PCB.
  5. Enhanced Capability
    Flexible PCBs help improve the performance of the electronic product by increasing its component density. It allows more electronic circuitry to the devices, enhancing the products’ capabilities.

Why Is Flexible PCB Prototyping Important?

Flexible PCB Prototyping enables the design of flexible boards that can be easily bent or folded into any shape-the reason why flexible PCBs are suitable for applications requiring high accuracy, improved performance, regular flexing, and precision. Flexible PCB Prototyping is commonly used in cameras, fuel pumps, antilock brakes, ultrasound probes, medical devices, avionics, satellites, semiconductor test, motion systems, manufacturing devices, barcode equipment, airbag systems, battery packs, etc.

Why Is Flexible PCB Prototyping Important?

Flexible PCB Prototyping is important for the following reasons:

1. Addresses the problem of packaging

  • Flexible PCBs creates designs that specifically solve interconnection related problems
  • Its forms allow the reduction of packaging sizes
  • Flexible PCBs makes repair and installation cost-effective and practical

2. Reduces assembly costs.

  • Flexible PCBs can be analyzed and tested before the circuitry components are assembled.
  • Elimination of solder joints and connectors and solder joints reduces costs.

3. Replaces wires and circuit boards

  • Flex circuits make the design of electronic systems and products simple.
  • Flex circuits minimize the number of interconnections required for an electronic package.
  • Flexible circuits reduce and eliminate common human errors in assembling wires as routing the wires is determined through artwork and repetition is assured.

4. Reduces space and weight.

  • Considerable reduction in weight is of a more significant benefit than wires.
  • Thickness of flexible PCBs can be as small as 0.10mm.

5. Dynamic Flexing

  • Its thinness and lightweight make flexible PCB suitable for numerous flexible electronic applications.

6. High-temperature application/Thermal management

  • Flexible PCBs dissipate heat easily and better compared to any dielectric material while offering the added advantage of improved flexibility.

7. Aesthetics

  • Flexible PCBs improve the appearance of internal electronic packages internally. This influences consumers’ decisions on the product.

Flexible PCB Prototype


Flexible PCBs are used widely in everyday technology and electronics, including:

  • Aerospace
  • Automotive
  • Communications
  • Consumer Electronics
  • Industrial
  • Medical
  • Military
  • Transportation
  • Wearables

The primary benefits of flexible circuits compared to traditional cabling and rigid PCBs include the following benefits.

  • Reduced Assembly Time and Costs
  • Unparalleled design flexibility
  • Ease of Installation
  • Ideal for high-density Applications
  • Improved heat dissipation
  • Stronger signal quality
  • Improved reliability and impedance control
  • Reduced Weight and Size

The different types of flexible PCBs available are:

  • Single-layer flexible PCB
  • Double-sided flexible PCB
  • Multilayer flexible PCB
  • Heavy copper flexible PCB
  • Rigid-flexible PCB

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.

A flexible circuit board is made of polyimide or polyester film, electro-deposited (ED) copper, Rolled Annealed (RA) copper, Constanta, and more based on customer specifications. This material dissipates heat better than most rigid printed circuit board materials.

Typically, rigid PCB boards cost less as compared to flexible circuits. However, the use of flexible circuit reduces the need for a number of components so you are looking at reduced cost of material and assembly.
