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.

YS Circuit
Flexible Circuit Boards, as the name suggests, are special types of circuits that can bend and adjust to the shape of the device and product in which they are installed.
They are made of a flexible substrate and have the capability to adapt according to the shape.

Physically, you can consider flexible printed circuit (FPC) boards just like a PCB with components, but the only difference is that the substrate can be bent.
The same components can be mounted on an FPC, and the same functionality can be obtained just like a normal rigid PCB.

There are special plastic substrates used to make a flexible circuit board.
It could be Polyimide or polyester film. Sometimes, you will see a polyester sheet and silver conductive lines on it;
We will introduce in detail later on Which material is used in flexible PCB.

These circuits are used in special projects when you care more about the compactness and minimalist design of the product.
It has greatly revolutionized the electronics industry and has significantly reduced the size of products or devices.

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
IPC-4101, Specification for Base Materials for Rigid and Multilayer Printed Boards
IPC-4202, Flexible Base Dielectrics for Use in Flexible Printed Circuitry
IPC-4204, Flexible Metal-Clad Dielectrics for Use in Fabrication of Flexible Printed CircuitryIPC-6013, Qualification and Performance Specification for Flexible Printed Wiring

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.

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.

Rigid-flex PCB simplifies the electronic design by eliminating flexible cables, connectors, and discrete wiring.
Its electrical performance has been enhanced compared to its counterparts because the circuit is an integral part of the overall structure.
All electrical and mechanical connections are contained in the rigid-flex PCB, providing electronic designers with greatly improved service reliability and electrical performance.

Although the cost of rigid-flex PCBs is usually higher than flexible PCBs and rigid PCBs.
However, rigid-flex PCBs’ reliability, weight reduction, strength, and space-saving advantages are generally ideal in specific applications and are superior to any other electronic packaging technology.
Ultimately, rigid-flex PCB provides the best benefits of rigid PCBs and flexible PCBs in one solution.
