Rigid-Flex PCB By Copper Thickness (6)
The thickness of copper on most PCBs is measured in ounces (oz). When PCB designers establish that the device’s capacity is normal, they choose the 1 oz Rigid-Flex PCB. It is a normal kind of PCB.
Different types of adhesives, such as polyimide (high TG) or polyester adhesive, can be used for 2 oz Rigid-Flex PCB. However, most designs use epoxy-based solutions to attach the Rigid-flex PCB together.
Thermal performance can be improved when components are surface treated with ENIG. Consider that when using a hefty copper PCB like the 3 oz Rigid-Flex PCB, it must be kept safe.
With a Flex component, we build the heavier 4 oz Rigid-Flex PCB. Gold and silver are among the surface treatments we use. We do this to prevent copper conductor oxidation while maintaining board solderability.
For a variety of reasons, people are drawn to use heavy-duty 6 oz Rigid-Flex PCB. It is used in heavy industrial applications such as mining and power generating. But so do telecommunications and space missions.
There is a configurable copper thickness with Flex component (Customized Rigid-Flex PCB) option. A variety of metal core materials, including as ceramic and aluminum, can be used. We want you to be satisfied.
Rigid-Flex PCB By Color (6)
If you buy Green Rigid-Flex PCB and other PCB stack-up orders from PCBTok, you will get excellent heat resistance and consistent performance. Altium PCB, complete with CAD designs and schematics, can be used.
Rigid-Flex PCB is mostly yellow in color, which is why customers often refer to Yellow Rigid-Flex PCB when ordering from PCBTok. The hue of the coverlay is frequently the cause of yellow flex’s tint.
Our good Blue Rigid-Flex PCBs are dependable for medical PCB materials since they have low defects. We have high-end rigid-flex PCB in stock, including ones with a High Tg, High Speed substrate.
The Black Rigid-Flex PCB has a stunning appearance. The LPI approach, which is a more complex method because the mask encloses both sides of the PCB, can be used. This ensures your protection.
Some clients choose the Orange Rigid-Flex PCB because they seek a more contrasted aesthetic. Despite the fact that most consumers prefer green solder masks, orange is a unique hue. We can accommodate it.
The Rigid and Flex components of a White Rigid-Flex PCB can be made distinctly. Some people utilize Taiflex or Dupont for the flex component. The rigid component is commonly made of FR4 or FR5 material.

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.
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
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.
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
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 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.
Rigid-Flex PCB Structure
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.
Please see this video:
An 8-layer rigid-flex PCB, for example, would have 6 layers of rigid components and 2 layers 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 PCBTok.
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.
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.
