What is Rigid Flex PCB?

Rigid flex printed circuit boards (PCBs) provide designers with one of the more unique packaging methods for electronic designs. Combining
the component and routing density of hardboards with the flexibility of flexible circuits, rigid flex PCBs allow designers to achieve routing
density and interconnectivity that is not available in other types of circuit boards.

Primarily used in military, medical and camera applications, rigid flex PCBs comprise about 1% of the overall PCB market, but they are
increasingly used in other electronic applications. They cost more than traditional hard boards and flexible circuits due to the raw materials
required; but, in the right applications, rigid flex PCBs dramatically outperform traditional rigid and flexible circuit boards, and they can be
more cost-effective in a full solution.

When Should You Use Rigid Flex PCBs?

When a designer needs a flexible solution & needs to rout components on both sides of the PCB
When a designer requires electronics fit the device, rather than the device conform to the electronics
When the electronic components & connectivity required max out space for connectors & flex cables
As a single-package solution for electronics with high input/output connectivity
As a cost-effective alternative to a combined assembly of interconnected hard boards
When the designer has to miniaturize their design to accommodate greater functionality
In weight-saving applications, such as drones, unmanned vehicles, aerospace & space applications
High vibration environments
High shock applications – where electronics will be subjected to 10,000+0 G-s
In never-fail electronics


Flex PCB is More Costly than Rigid One, Why ?

It is about complexity and the number of material and process involved to make your flex PCB done. Flex PCB manufacturing has the same
rigid pcb steps in addition to other ones.
It’s clearly that flex pcb has more complexity and human interaction than the usual rigid boards : more cost!

Rigid-Flex PCB Applications

The rigid-flex PCB has various applications in different types of accessories and equipment that we use daily. One of its most apparent uses
comes in a smartphone application.

Nowadays, smartphones have to be incredibly thin yet very functional, which can only be achieved using rigid-flex technology.

Another famous application of rigid-flex PCB comes in various computer electronics, all of which use rigid-flex PCB.

One of the many components that use rigid-flex technology is the hard drive; it keeps up with the ever-increasing write speeds of today’s

Using a rigid flex for a hard drive is excellent as it keeps the hard drive cool even when it is working at its peak.

Rigid-flex PCB is also used in the field of medicine. Most recently, the pill cam allows you to see the inside of a person’s stomach to examine
the internal damage. This pill is made of well-designed rigid-flex circuits that are very effective.
