Rigid-Flex PCB – The Completed FAQ Guide

If you have the right tools and resources, rigid-flex PCB design isn’t an intimidating process for designers. With tools that include integrated 3D design features, designing rigid-flex PCBs is a breeze. Altium Designer unifies these features into a single platform and interface. You’ll learn everything you need to know about designing a rigid-flex PCB and getting started on your project right here.

What Is Rigid-Flex PCB?

Rigid-flex PCBs are an excellent choice for designing and manufacturing electronic products for a variety of reasons. They are adaptable, support multiple signal layers, and can improve reliability.

They also make assembly easier and save money. Foldable and bendable electronics can monitor vital signs, act as conformal heating elements, and do other things. Rigid-flex PCBs can also help to streamline the development process and reduce costs.

Depending on the application, rigid-flex printed circuit boards can be single, double, or even four layers thick. The number of layers is proportional to the size and shape of the object. Essentially, layers are like ingredients in a great recipe: each one contributes to the overall flavor.

Multilayer Rigid-Flex PCB

Multilayer Rigid-Flex PCB

The process of stacking layers, on the other hand, is relatively simple and should be aided by a visual aid. A 3-D model of a rigid-flex PCB, for example, allows designers to more precisely define the bending region.

The copper coil must be cleaned before the rigid-flex PCB manufacturing process can begin. The anti-rust layer prevents oxidation, which would otherwise impede the rigid-flex PCB manufacturing process. To prevent oxidation, copper foil is usually treated with a sodium persulfate or acid solution after cleaning.

Finally, it is coated with an appropriate oxidant. If you need to design a Rigid-Flex PCB with a copper foil layer, use OrCAD PCB Designer, which is optimized for this type of design.

Another advantage of rigid-flex PCBs is their small size. Rigid-flex PCBs are intended to fit more components into a smaller space, lowering the cost per unit.

They also have fewer interconnects, which makes automated testing easier. They are also ideal for prototyping. These benefits make rigid-flex PCBs an excellent choice for a wide range of industries.

Where Are Rigid-Flex PCBs Used?

In this paragraph, we will look at how rigid-flex PCBs can be customized for specific applications. In many cases, they are ideal for applications requiring board flexibility or bending. However, there are some important design considerations to bear in mind. Here are a few things to remember:

Miniaturization is ideal for rigid-flex PCBs. They can fit into small electronic devices and be bent into various shapes, making them ideal for designers. Because of their smaller size, they are also lightweight. Because of their adaptability, they can be easily mounted and removed from small devices.

They are used in consumer electronics such as music keyboards, televisions, and toys. Flex PCBs are better suited to high-performance applications like industrial components.

Engineers can create smaller, lighter applications with rigid-flex PCBs while still meeting all requirements. These boards are especially useful for high-temperature applications where rigid-flex PCBs can be molded to specific specifications. With the right design tools, designing a rigid-flex PCB is a relatively simple process.

You can even use PCB designer software to create your own rigid-flex PCB. This allows you to easily meet the needs of your customers and your business.

Rigid-Flex PCB Sample

Rigid-Flex PCB Sample

A rigid-flex PCB assembly process consists of three steps: production, manufacture, and assembly. First, a cover layer, which is a thin film that acts as a protective barrier over the assembled circuit, is used. The second step is an etching, which involves removing copper between layers and then covering the circuitry with a cover layer. The rigid-flex PCB will be ready for use once the process is completed.

What Are the Advantages of Rigid Flex PCBs?

When designing a flexible circuit board, rigid-flex PCBs offer several advantages. They enable manufacturers to create circuit boards that precisely fit a device, reducing package size and weight. Furthermore, they facilitate the automation of test and verification processes, preventing costly errors or material waste.

Some of the advantages of rigid-flex PCBs are listed below. Check out this guide if you’re looking for a low-cost way to improve the design of your product.

They are often used in electronic products, which require a small footprint. They fit into a variety of electronic devices due to their small size. Furthermore, because these boards are lighter, they are an excellent choice for miniature electronic devices.

They are also bendable, allowing them to fit into smaller devices. As a result, they make a product much smaller and easier to transport.

Advantages of Rigid Flex PCBs

Advantages of Rigid Flex PCBs

Rigid-flex PCBs are flexible and bendable to some extent. However, the bend area must be carefully designed to avoid mechanical stress destroying the pads. Traces should be routed perpendicular to the bend line to reduce mechanical stress on pads in the bend area.

Dummy traces can be placed in the flex area to strengthen it if possible. Finally, for the flex area, a hatched-polygon ground plane should be used. OrCAD PCB Designer is an excellent PCB design software tool for rigid-flex designs.

Rigid-flex boards are generally less expensive to manufacture than traditional printed circuit boards, which is an important consideration if you need a small, compact device.

Furthermore, rigid-flex PCBs require fewer interconnects and can withstand harsh conditions when compared to wired PCBs. They’re also simple to test, which is ideal for prototyping.

How to Design the Rigid-Flex PCB?

How to Create a Rigid-Flex PCB will provide answers to these and other questions. Flex PCB construction is IPC 2223C compliant and has many advantages, including long-term reliability and lower design costs. Engineers can place components on flexible areas without sacrificing structural integrity on rigid-flex PCBs, which are typically multilayer.

Another option is an asymmetrical design, which is frequently driven by complex impedance requirements. These designs improve manufacturability and reduce blindness through aspect ratio.

It is critical to avoid stress and weak points when designing a flex circuit. Traces placed at right angles to corners should be avoided because they will cause strains on the copper traces.

However, there are some design considerations that will necessitate bending at corners. To accomplish this, bend the copper traces with a conical radius. Aside from that, avoid excessively sharp bends, as these will put more strain on copper traces.

An eight-layer rigid-flex PCB, for example, would have six layers of rigid components and one layer of flex components. The flex layer would be shifted toward the bottom of the structure rather than to the center.

With no major manufacturing issues, this configuration would still be a viable manufacturable configuration. If you’re not sure how to design the Rigid-Flex PCB, consult with a PCB design expert.

Asymmetrical Rigid-Flex PCB construction is standard. This is because it reduces stress points and makes manufacturing easier. Rigid-flex PCBs typically have 20 layers or less but can have up to 40 layers if necessary.

The overall thickness of these boards is typically the same. A design with varying layer counts is more difficult to manufacture.

What Are the Applications of Rigid-Flex PCB?

Rigid-flex circuit boards have a wide range of applications, from commercial and industrial to military and medical. They provide the advantages of flexibility without sacrificing rigidity, making them ideal for these applications. Indeed, because these circuit boards are so adaptable, they are sometimes used in smart devices.

They are commonly used in pacemakers in the medical industry. Because it has fewer solder joints, this type of circuit board has fewer connection issues and is more reliable. It can also be used in testing and automotive applications.

Application of Rigid-Flex PCB

Application of Rigid-Flex PCB

The most common application for rigid-flex PCBs is in gadget assembly, where the flex PCB is placed over the rigid board when the device is assembled and evacuated.

Because the flex portion of the PCB remains stable despite the strains, this type of circuit board is useful for applications with a high level of vibration. The bend line is critical to the circuit’s operation and routine.

The properties of rigid-flex PCBs are determined by the substrate material. The polyester dielectric film is typically used in low-finish applications. Another common material for flexible dielectric films is polyimide.

Fluoropolymers are used in military applications. Rigid-flex printed circuit boards are also used in ultra-small and dense packaging.

What Is the Stack-Up of Rigid-Flex PCB?

To be a valid product, a rigid-flex PCB must adhere to the IPC 2223C design guidelines. This stack-up identifies the thickness and material type of each PCB layer. Flex circuitry is divided into several areas, some of which are more critical than others. As a result, before any manufacturing can begin, this information must be thoroughly reviewed.

A multilayer PCB employs a multilayer approach, similar to how Legos are constructed. Each layer of the PCB is made up of different insulators that are connected by vias and plated through holes. Because these vias form active circuitry between the layers, the PCB is a versatile option for a wide range of applications. Rigid-flex PCBs are also lightweight, which makes them an ideal replacement for wire harnesses.

The rigid-flex PCB is useful when warping is unavoidable or when space is at a premium. Rigid-flex PCBs have grown in popularity in recent years, and they can now be found in almost every market segment. They are widely used in military, aerospace, instrumentation, automotive, and industrial sensors. The advantages of rigid-flex PCBs are substantial, but there are some drawbacks.

Despite their flexibility, rigid-flex PCBs can be damaged during handling and use. Rigid-flex PCBs are made from a variety of materials, and the material used is determined by the application. Epoxy resin or woven fiberglass are two alternatives, but they are less reliable than polyimide. Polyimide is the best material for this application. These materials are more flexible and have better conductive properties.

How to Choose a Reliable Rigid-Flex PCB Supplier?

In addition to the manufacturer’s technical expertise, you should ensure that the Rigid-Flex PCB supplier can produce quality products on the first try. Some important characteristics to look for in a dependable rigid-flex PCB supplier include the ability to produce high-quality, precision-made products and the use of high-quality materials.

The trace on a rigid-flex PCB determines the board’s speed and voltage. A solder mask protects the board from corrosion on a high-quality rigid-flex PCB. If the solder mask is applied incorrectly, the circuit board may crack or corrode.

While rigid-flex PCBs require high-end equipment and specialized software to manufacture, these boards are available from a variety of PCB manufacturers.

When selecting a supplier, look for one with extensive experience in rigid-flex PCB manufacturing. Not all manufacturers have the resources or experience required to produce these boards, so choosing a manufacturer with sufficient expertise is critical.

Experience is another important consideration when choosing a rigid-flex PCB supplier. Rigid-Flex PCBs are more expensive than rigid-flex circuits, but they use higher-quality components.

Rigid-Flex PCBs are frequently constructed from special raw materials such as adhesives and flexible laminates. Furthermore, specialized components, such as thicker flex dielectrics in the impedance layers, are used in their design.
