What is a Rigid Flex PCB?
Rigid-Flex printed circuit boards are boards using a combination of
flexible and rigid board technologies in an application.
The proper application of Rigid-Flex circuit boards offers optimum
solutions for difficult, limited space conditions. This technology
offers the possibility of a secure connection of device components
with the assurance of polarity and contact stability, as well as a
reduction in plug and connector components.
Additional advantages of Rigid-Flex circuit boards are dynamic and
mechanical stability, the resulting 3-dimensional freedom of
design, simplified installation, space savings, and maintenance of
uniform electrical characteristics.

4. 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-4203, Adhesive Coated Dielectric Films for Use as Cover Sheets
for Flexible Printed Circuitry and Flexible Adhesive Bonding Films
IPC-4204, Flexible Metal-Clad Dielectrics for Use in Fabrication of
Flexible Printed CircuitryIPC-6013, Qualification and Performance
Specification for Flexible Printed Wiring
5. 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.
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.
