What is Rigid flex PCBs?


RigidflexPCBs combine the benefits of flexible and stiff board technologies.These PCBs provide mechanism reliability in condensed packages of extreme conditions that may not be tolerable for connectors.Depending on the application, most rigid-flex boards have some layers of flexible circuit substrates linked to one or more rigid boards externally and/or internally.Flexible substrates are made in a constant state of flex and can be frequently bent into a flexed curve during the complete lifecycle of the product.

Advantages of rigid-flex PCBs



By combining the properties of rigid and flexible PCBs, rigid-flex PCBs come with a host of benefits for both manufacturers and consumers.

Mechanical stability- Their basic structure consists of interchanging layers of rigid and flexible PCBs.This ensures that they're both stable and flexible, facilitating easy installation in small spaces.

Connection reliability- With rigid-flex PCBs, you get greater stability and polarity, making connections easier and more secure with other components.You will also require fewer connector components with each application.

Dynamism- Along with repeatability and precision, you'll enjoy greater flexibility with packaging.

Cost-effective- By using rigid-flex PCBs, you can cut down on the total expenditures.

High-density applications- Arguably, the best benefit of rigid-flex PCBs is that they can be used for a high-density device population.This is due to their flexibility, stability, and low space use.

High shock and vibration resistance- Electronic components are used in a wide range of items, some of which experience constant vibrations.With such devices, you won't have to worry about damage as rigid-flex PCB is highly resistant to shock and vibration.


PCBmanufacturer talk Rigid PCB vs.Flexible PCB: which is better?


The debate between rigid PCB vs. flexible PCB has been raging on for some time.To determine which is ideal, it's best first to understand how they compare to each other.


First, rigid PCBs are the standard type of PCB and are what come to most people's minds when they think of circuit boards.They use conductive tracks and other elements arranged on a non-conductive substrate to connect electrical components.Usually, the non-conductive substrate also contains glass to make the board stronger.Along with firm support, rigid circuit boards offer electrical components great thermal resistance.


Other than rigidity and the base layer material, flexible and rigid PCBs also have some notable differences.These include:


Manufacturing process: Rigid PCBs are made using a solder mask.However, with flexible PCB design, a process known as coverlay or overlay is used.This ensures the exposed circuitry of the flexible PCB is protected.

Conductive material: Unlike rigid PCB, a flexible PCB board should be able to bend.To achieve this property, a flexible rolled annealed copper is used as a conductive material instead of electro-deposited copper.

Cost: Rigid PCB is cheaper than flexible circuit boards.However, you should be willing to incur flexible PCB costs when you need a PCB that can fit in compact spaces.
