Single Flex Substrate Rigid-Flex PCB

 

Rigid-flex PCB - Overview

A rigid-flex PCB is a printed circuit board that combines both rigid and flexible circuit technologies in a single design, allowing for the creation of complex, space-saving, and durable electronic assemblies. These hybrid boards consist of rigid sections that support component mounting and flexible sections that enable bending or folding, eliminating the need for separate flexible circuits, cables, and connectors, thereby increasing reliability and improving signal integrity.

 

Advantages of Rigid-flex PCB

 

Space Efficiency

Rigid-flex PCBs are highly space-efficient, as they eliminate the need for connectors and reduce the need for additional interconnects. They can be folded or bent to fit within tight spaces, making them ideal for compact and densely packed electronic devices.

01

Reliability

Fewer connectors mean fewer potential points of failure, improving overall system reliability. Rigid-flex PCBs are less prone to connector-related issues.

02

Durability

Rigid-flex PCBs are designed to withstand mechanical stress, vibrations, and temperature variations, making them suitable for applications in harsh environments.

03

Reduced Assembly Costs

Despite the initial complexity of manufacturing, rigid-flex PCBs often result in reduced assembly costs due to fewer components and manual assembly steps.

04

Complex Geometries

Rigid-flex technology enables the creation of complex board shapes and three-dimensional configurations that are challenging to achieve with traditional PCBs.

05

 

Applications of Rigid-Flex PCBs
 

Medical Devices

Used in pacemakers, imaging systems, and diagnostic tools for their reliability and compact size.

Military Systems

Essential for communication systems, navigation equipment, and weapon systems due to their robustness.

Aerospace Systems

Used in satellites, avionics, and UAVs for their ability to withstand extreme conditions.

Automotive Electronics

Found in infotainment systems, sensors, and ECUs for their durability under constant vibrations and temperature changes.

Industrial Equipment

Ideal for harsh industrial environments due to their durability and reliability.

Consumer Electronics

Used in smartphones, wearables, and laptops for their slim profiles and reliability.

 

Rigid Flex PCB Assembly Process

Assembling rigid-flex PCBs requires specialized circuit board assembly technologies and processes. Unlike traditional PCBs, rigid-flex PCBs have many layers of rigid and flexible circuits. So, the assembly process for rigid-flex PCBs is more complex.

 

The first step in the manufacturing process is to create the rigid-flex PCB stack-up. This involves laying down the flexible and rigid layers in their proper order.

 

Then, an assembler adds the components to a pick-and-place machine. This machine can identify and arrange both rigid and flexible components.

 

After placement, the components get laminated together. Then, assemblers remove excess materials from the rigid-flex board.

 

Finally, the assembler performs post-processes, such as applying finishes, soldering, and drilling. Once that’s finished, the rigid flex PCB is ready to package and ship.

FAQ

 

Q: What is an example of a rigid PCB?

A: The computer motherboard is the best example of a rigid PCB with a rigid substrate material. Once rigid PCBs are manufactured, they cannot be modified or folded into any other shape. Rigid PCB is cheaper than flexible PCB. They are traditional PCBs and are widely used in many electronic products.

Q: What is a rigid-flex PCB used for?

A: This 3D capability provides excellent spatial efficiency, making Rigid-Flex PCBs ideal for applications where space and weight reduction are critical, such as in medical devices, aerospace, and consumer electronics.

Q: How do you connect a flex PCB to a rigid PCB?

A: Soldering
One of the most common and straightforward methods of connecting a flex PCB to a rigid PCB is through soldering. This technique involves soldering the flex PCB's exposed copper pads directly to the corresponding pads on the rigid PCB.

Q: How to make rigid-flex PCB?

A: Essentially, each rigid panel is separately routed out in the areas where the flex is going to be allowed to, well, flex. Here is an example process of laminating into a rigid-flex board, with two, 2-layer flex circuits embedded between three rigid sections. The layer stack-up would look like that shown below.

Q: What materials are used in rigid flex?

A: The Flexible Core: Polyimide Film. ...
The Rigid Core: FR4 and Polyimide Laminates. ...
No Flow Prepregs. ...
Conductive Layers: Copper Foil. ...
Protective Layers: Coverlay and Soldermask. ...
Supporting Materials: Adhesives and Stiffeners.

Q: How many layers does a flex PCB have?

A: Flex PCBs can be classified into rigid-flex PCBs and high-density interconnect (HDI) rigid-flex PCBs. The number of layers of flex PCBs vary between 1 and 6. It is preferable to limit the number of layers to a max of 2 for greater cost benefits and mechanical flexibility.

Q: Are you manufacturer or trading company?

A: We are manufacturer.

Q: What's your best delivery time?

A: Within 15-30 days.

Q: What is the quality control of your product?

A: Follow strictly quality control measures for implementation,

Q: Will your company provide free sample?

A: It depends on which sort of item you want to get. Some can be provided free of charge, however, the client shall assume the shipping fees himself.

Q: Is OEM open to clients?

A: Yes, we can provide both OEM and ODM service.

Q: How can our company be your distribution partner?

A: We welcome you to be our distributor. For further details, please contact us.

Q: What is the payment of sample?

A: T/T and Alipay both acceptable.

Q: What is your packing?

A: Yes, our packaging is genuine original packaging. Of course, we can also provide neutral packaging or according to your requirements

Q: What is your sample policy?

A: If we have stock, we can provide samples, but the customer must pay the sample fee and express fee Question

Q: Have you tested all your goods before shipment?

A: Yes, we will conduct 100% test before delivery, and we will send detailed photos of parts for your approval Question .

Q: How can you maintain a long-term good relationship with our business?

A: We maintain good quality and competitive prices to ensure the interests of our customers.
