A rigid PCB is a go-to for product designers due to its minimal cost, optimal performance, easy repair, and various other features. But it is made of a hard substrate or core, which is why it cannot bend according to the shape of the product.
On the other hand, a flexible PCB can bend easily and take the shape of the product. It can be adjusted in small and confined spaces, but these special features come at a hefty cost. Secondly, these PCBs have a limited size, limited functionality, and other constraints and disadvantages.
Thus, there is a dire need for a PCB that can offer the advantages of both flexible PCBs and rigid PCBs at a reasonable cost. That is where the Rigid-Flex PCBs come into play.
A Rigid Flex PCB comes in the middle of a Rigid PCB and a Flexible PCB. We can call it a hybrid PCB because it is a mixture or combination of both types of PCBs to get the best results at the lowest cost.
Certain parts of the Rigid-Flex PCBs are made of rigid PCBs, while the remaining contain flexible PCBs. The combination is tweaked according to the needs of the product to offer more flexibility in the design. These PCBs can be used in confined spaces with bends and corners.
Usually, flexible PCBs are used to connect one or more rigid PCBs in a Rigid-Flex circuit. They serve as a bendable connection and can easily be placed in any place or product where the space is limited or confined. Due to the flexibility of the flexible part, the PCB is able to acquire intricate shapes, and the connections become more reliable and long-lasting.
Note: The flexible and rigid part can be soldered, or there can be a connecting male and female plug.
The components are mostly placed on the rigid part, which can have more component density and can easily bear the weight. Secondly, it is also cost-effective. The flexible part does not have components in most cases, and they are used for interconnection only.
As a rigid-flex PCB manufacturer, we offer both prototyping and mass-production services to meet our customers’ diverse needs.
The rigid part of the PCB is usually made of FR4; however, it can be customized according to the needs of the customers. The core can be of aluminum, copper, etc. It is just like a common rigid PCB you see in devices. All the components of the PCB are placed on the rigid part because it can bear the weight and does not bend.
The flexible part is made of flexible material, such as polyimide. It contains a conducting circuit that is made of copper, just like a normal PCB. It connects one rigid board to another through the conducting layer and ensures optimal conductivity of the current.
Rigid Flex PCBs are used for a wide range of purposes, and you will have yourself surrounded by products that contain such kinds of PCBs. For instance, the computer, laptop, or mobile phone you are using also contains rigid-flex PCBs.
These PCBs are used in military applications, aerospace, automobiles, cameras, smart devices, and tons of other places where normal rigid PCBs cannot work, or a compact design is a priority. These PCBs help in making the final product smaller, more reliable, and more efficient.
At JHYPCB, we specialize in making simple to complex rigid flex PCBs with utmost accuracy and performance. We can create custom Rigid Flex PCBs according to the requirements of the buyer and offer reasonable prices along with exceptional service and quality. We offer PCB manufacturing and prototype services for almost any kind of PCB, from low to high-volume orders.
Rigid-flex PCBs are a hybrid of rigid and flexible PCBs that are used to interconnect rigid and flexible circuits. They consist of multiple layers of rigid and flexible circuits that are bonded together.
Rigid-flex PCBs offer several advantages, including improved reliability, reduced weight, increased durability, and reduced assembly time and costs. They also provide better signal quality and can be designed to fit into tight spaces.
The materials used to make rigid-flex PCBs include a combination of rigid materials, such as FR-4 or polyimide, and flexible materials, such as polyimide or polyethylene terephthalate (PET). Copper is used for the conductive traces and vias.
Design considerations for rigid-flex PCBs include bend radius, material selection, via placement, routing, and stack-up design. These considerations are critical to ensure the proper function and reliability of the PCB.
Rigid-flex PCBs are ideal for applications that require flexibility, durability, and high reliability. They are commonly used in aerospace, military, medical, and automotive industries, as well as in consumer electronics and telecommunications.
Rigid-flex PCBs are used in a wide range of applications, including medical devices, aerospace and defense, industrial automation, consumer electronics, and automotive electronics. They are particularly suitable for applications that require high reliability, durability, and flexibility.
Rigid-flex PCBs present several challenges in manufacturing, such as ensuring proper alignment and bonding of rigid and flexible layers, avoiding stress on the flexible layers during assembly, and minimizing the risk of delamination or cracking.
Rigid-flex PCBs are tested using various methods, such as visual inspection, electrical testing, and mechanical testing. Electrical testing includes continuity testing, impedance testing, and signal integrity testing, while mechanical testing includes flex testing, vibration testing, and thermal cycling.
