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.

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. 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.
6. 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.
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.
