What Are Flexible Circuit Boards ?

Flexible PCB Definition, For a new product to be better applied, we need to understand exactly what it means and everything about it.
Flexible PCB, also known as flexible electronics, flexible circuit board, Flex PCB, Flexi board, flex circuits.

The IPC defines a flexible printed circuit as “a patterned arrangement of printed circuitry and components that utilizes flexible base material with or without flexible cover lay.” This definition, while basic, illustrates what you can expect from a flex PCB – a bendable printed circuit that is made of a flexible film.

Flex PCBs, however, have become far more complex over the years as they have been applied to industries across the board. Below, we examine some of the most common types of flexible printed circuit boards being used today.

FQA

1. Do you offer double-layer flexible PCB?
Yes, we make single layer flexible PCB, double sided flexible PCB, multi-layer flexible PCB, and Rigid-Flex PCBs.

2. How many types of flexible circuit do you make?
We make different types of Flex and Rigid-Flex PCBs, depending on the structure, base material, adhesive, appearance, insulation base film, and metal conductor foil. Please consult our technical team for details suitable for your application.

3. Do you provide stiffeners and cover films?
Yes, we provide black PI stiffeners, yellow PI cover films, transparent polyimide films, white overlay, and brown PI copper clad laminates.

4. Do you use adhesive free copper foil base material?
Yes. We have four manufacturing methods for adhesive-free copper foil base materials. We use spray plating, curtain coating, electroless deposition/electrolytic plating, and laminating.

5. What are the minimum and maximum thickness of your adhesive flex PCBs?
Minimum thickness is 2 µm and the maximum is 200 µm.
We ensure high chemical durability and processing compatibility for flexible printed circuits and do not sacrifice its original electrical property, heat-resistant property, and mechanical property.

6. Which IPC standards do you follow?
IPC Standards for Rigid and Flexible PCBs
The list of IPC standards below applies to rigid PCBs and flex circuits. Take note that this list is not exhaustive, and additional IPC standards may need to be considered.
You should consult the ipc.org website for a full list of available IPC standards.

IPC-2221A, Generic Standard on Printed Board Design
IPC-2223, Sectional Design Standard for Flexible Printed Boards

7. What is the function of the flexible circuit board?
The functions of flexible circuit boards can be divided into four types: Lead Line, Printed Circuit, Connector, and Integration of Function.
The use covers computers and computer peripherals—auxiliary systems, consumer electrical appliances, automobiles, etc.
After the circuit is completed with single-sided PI copper-clad material, it is covered with a protective film to form a flexible circuit board with only a single-layer conductor.

8. Rigid-flex PCB vs. rigid PCBs and flexible PCB, What are the differences?
As the name suggests, rigid-flex PCB is a mixture of rigid and flexible PCBs.
Rigid-flex PCBs combine the excellent qualities of both while eliminating many of their limitations.
Rigid-flex PCBs combine flex circuit design with rigid materials.

By layering the flexible PCB board inside the rigid printed circuit board material, the versatility of the flexible printed circuit is finally combined with the stability, strength, and circuit wiring density of the rigid printed circuit board.
This mixing opens possibilities for more complex and mechanically challenging rigid-flex PCB designs.
