What is a Rigid Flex PCB?
Printed Circuits Rigid Flex PCBA rigid flex printed circuit board
(PCB) is a hybrid circuit board design that integrates elements
from both hardboard and flexible circuits. Rigid flex PCBs are
rigid at some points on the board and flexible at others. Because
of this, rigid flex circuits can be folded or continuously flexed
while maintaining the shape of areas that need extra support. The
circuits are typically multi-layered and are comprised of flexible
circuit substrates joined with rigid boards. The flexible layers
are buried internally and completely penetrate the rigid sections
of the PCB.
One of the key benefits of a rigid flex PCB is its slim profile.
The standard dielectric in flexible circuits is .001 – .002”,
making it a great choice for ultra thin—and ultra light—packaging
needs. Adhesiveless laminates, HDI, and thin copper layers make it
ideal for fine line technology, giving you the smallest, thinnest,
and lightest solution for your circuit designs.
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.
Use of Rigid-Flex circuit boards can reduce the total cost of the
