What is Rigid Flex PCB?

Rigid-Flex printed circuit boards make use of the combination of rigid and flexible board technologies to create an application. As we know, Multiple layers of flexible circuit substrates are typically attached to rigid boards, externally and/or internally, depending on upon the design of the application. During manufacture or installation, the flexible substrates are usually shaped into the flexed curve so that they remain in a constant state of flex.

The rigid-flex designs are more complex than the designs of the typical rigid board environment because the boards are created in a 3D space. This also provides more efficiency in spatial space.

Flexible board substrates can be twisted, folded, and rolled as necessary to achieve the desired shape for an application’s package when rigid flex designers design in three dimensions.

What are the Types of Flex-rigid?

How many type the rigid-flex printed circuit, Let’s look at them.

Single-sided Flex-rigid Board:

In the case of Single-side flex-rigid PCB, it features only one layer of conductive material in contrast to the double-sided configurations. The reverse side accommodates the accommodation of diverse electronic components onto the circuit board. Constituted of a singular layer of flex-rigid substrates conjoined, they stand apart from other rigid-flex iterations. Their production and design are notably straightforward, making them less complex compared to their counterparts.

Double-sided Rigid-flex Printed Circuit Board:

For Double-Sided flex-rigid boards they consist of one rigid substrate layer and the another layer is flexible substrate. In contrast, the flex substrate is essential for enhancing flexibility, while the rigid layer enhances compactness.

Additionally, double-sided rigid PCBs that flex can allow more routing lines. The vias enable this and switch between the two layers. A majority of PCB engineers favor this kind of flexible-rigid PCB because of its flexibility and its capacity to reduce the size of the board.

Multilayer Flex-rigid Board:

In this rigid-flex, either or both substrates contain at least three conductive layers. These substrates function as an insulator.

Flex circuits: Double-sided, single-sided and multi-layered circuits.

Single-layer Flex PCB:

Single Sided Flex PCB Polymide Substrate Copper Pad Coverlay

Single-sided is the simplest kind of flexible printed circuit board. . They consist of a single conductor layer positioned on a flexible substrate, usually bonded with a flexible polyimide layer onto a thin copper sheet. Through the substrate, holes are drilled to allow for the passage of component leads during soldering. Additionally, a coverlay made of polyimide material can be applied to safeguard the circuit and provide protection against environmental factors.

Duoble-layers Flexible PCB:

When it comes to double-sided flexible printed circuit boards, they feature two conductive layers, one situated on each side of the flexible substrate. The affixing of copper foils on both sides results in these conductive layers. The circuit layer’s electronic connections are formed through the plated vias or holes. These boards can potentially possess protective layers on a singular side, both sides, or not at all, as dictated by the specifications of the circuit’s design

Multi-Layers Flex PCB Circuit Board

In multilayered flex circuits, they have more than two copper conductors. The circuits are interconnected by PTHs or vias, and they are the best solution to overcome design challenges like specific impedance requirements, unpreventable crossovers, crosstalk, and high component density.

Rigid Flex PCB

A rigid-flexible PCB is a mixture of flexible and rigid technology. It is a case where some or all flex circuits are utilized to connect circuits within stiff PCBs. The flexible portion of rigid-flex is usually multilayered.

Aspects Considerations of Material Layup

Layups of rigid-flex materials significantly affect the cost, manufacturing, and PCB’s final performance. As a result, the most appropriate material set must be considered. For example, controlled impedance, resistance, and current-carrying needs are all crucial factors that influence copper weights and the choice of material.

A PCB designer must collaborate with the fabricator of their board to discuss these variables to ensure that the final design meets the requirements of signal integrity. After the designer has completed preliminary calculations, the fabricator can validate them and provide a more precise model of the impedance characteristics of the board as well as the materials required to get those values.

If impedance properties are not of paramount importance, your priority would likely be achieving the most cost-effective and reliable design. For a quick estimate of the potential cost of your rigid-flex design, you can contact our oversea representatives. Our rigid-flex cost estimator will assess your requirements and furnish you with an estimate tailored to lower production volumes. This initial evaluation serves as a valuable starting point for gauging the financial viability of your project and ensuring alignment with your program’s objectives.

For the majority of rigid-flex boards, typically, a maximum of twenty layers defines the rigid sections. Instances exceeding this number do occur, albeit infrequently. It’s important to note that identical layer count for every section of the rigid board isn’t obligatory. For example, a configuration could comprise a section with sixteen layers of circuitry contrasted with another having twelve layers. Provided the material layout is congruent across all and each board maintains uniform overall thickness, manufacturing issues are unlikely to arise. There are design scenarios where rigid boards of varying thicknesses are utilized. Though, it’s important to remember that such designs pose considerable fabrication challenges, so exploring alternative solutions would be advisable.

Flexible sections on rigid boards usually comprise one (singlet) or two (doublet), or triplet) (triplet) and four layers (quad construction). There are times where a designer may require greater than 4 layers on the flexible portions of the board, but they the majority of them are not bonded.

The flex sections with bonds with at least four layers may be very resistant to bending or being flexed. Copper weights placed on those flexible sections of the rigid-flex board are typically one-ounce and half-ounce weights.

Sometimes, the electrical requirement requires two-ounce weights. In such cases, the designer must be in close contact with their fabricator to select the proper no-flow prepregs to fully fill the circuits on the hardboards.

Due to the design of no flow prepreg, it doesn’t like to flow, and two-ounce circuitry can be challenging. Three-ounce copper weights are rarely used and can also pose significant manufacturing challenges.

Utilizing an experienced manufacturer of rigid-flex PCB technologies like JarnisTech during the early stages of the process can make sure that both the design and the manufacturing process are in sync coordination, making the finished product successful.

The earlier requirement for the quick association is essential because the production of rigid-flex PCBs is more time-consuming and complex compared to making standard rigid boards. Flexible components that are used in the production of flexible circuits demand completely different techniques for the handling of etching, drilling and soldering procedures in comparison to the processes used for normal rigid PCB boards, which take more time-consuming.
