The PCB board is a rigid green board where different components are connected. It is the best option for getting miniaturization results for different PCB substrate types. The main solution is to use a flexible substrate that is made with polymeric materials like polyimide. Flexible PCBs have features for folding nature and are easy to bend for making different surface shapes and dimensions. With the rigid and flexible substrate combination called a rigid flex board, it is not commonly used for different electronic devices and projects. Aviation and the medical industry are the main parts where rigid-flex boards are used. In this post, we will discuss details for rigid-flex board assembly with its uses for different industries. Let’s get started with
What is Rigid-Flex PCB Assembly?
Rigid-flex PCB assembly is a combination of rigid and flexible boards in a single component. The rigid-flex board is a PCB type that comes with features of flexible and rigid laminate materials.
This hybrid technology helps to make professional designs that have features for different device designs.
The flexible board can easily bend for different structures. This feature helps to make more structural options than rigid boards that do not have these features.
Rigid-flex boards come with different layers of flexible substrate for rigid boards that are electrically configured with conductive vias or plated through holes.
It is used for the aviation industry and medical devices to provide high efficiency and reliability.
Rigid Flex PCB Assembly in Aerospace and Medical Applications
Lightweight
- The main objective of aviation devices is to get low-weight designs for increasing overall efficiency and fuel outcomes. The use of rigid-flex board controls the use of heavy wiring and connectors and also reduces the weight of the system.
Compact Design.
- With less weight, the dimensions of electronic devices are also minimized through the use of rigid-flex boards. The flexible part of the board can be folded and bent into different shapes. This feature is important to use for medical devices. These features also help in avionics and satellite systems and can get the benefit of the compactness of rigid-flex PCB designs.
Performance and Reliability.
- Aviation industries are involved in harsh conditions since they have high temperatures, humidity, radiation, and vibrations. The rigid part of the board increases the structural rigidity of the device; the flexible part also easily handles mechanical stress, helping to increase working life. The reduction of using heavy connectors also makes design simple, reducing chances of damage.
Signal quality
- The use of heavy communication integration and data transmission through wireless features and remote monitoring, that assembly helps to increase signal quality. The use of connectors and cables also causes distortion or interference of signals. The replacement with rigid-flex boards is reliable data and signal transfer.
Rigid-Flex PCB in Aerospace Industry
Satellite Systems:
- Rigid flex board is the best option for harsh conditions that operate satellite systems. Its durable nature and low weight are best to use for good working performance.
Aircraft:
- Aircraft come with heavy components that must be according to reliable and safe parameters of the industry. A rigid-flex board is best for aircraft systems of communication and navigation control.
Unmanned Aerial Vehicles (UAVs):
- Drone technology and other UAVs are mostly used for surveying and military features. These UAVs come with a rigid-flex board for sensing and controlling units for good working operations.
Defense Systems:
- The mixture of rigid and flexible design helps to provide design features for the aviation design system. Low mass and dynamic flexing are strong and vibration-resistant features for rigid-flex boards and are best for use in defense systems like missiles and aircraft.
Applications of Rigid-Flex PCB in the Medical Industry?
Wearables.
- The monitoring of important signs is made with different inventions of wearables. The circuit in wearables is made with light, rigid flex boards that are used for 3D volume maximization.
Medical Implants.
- The final form factor is reduced with the use of a special rigid-flex board, medical implants like pacemakers based on rigid-flex PCBs for simple connections.
Diagnostic Instruments
- High-accuracy diagnostic instruments also come with a rigid flex board, and these devices come with MRI, CT scanners, and imaging devices. Rigid flex circuits help to make simple system-level designs remove the use of wires and connectors.
Future factors for Rigid-Flex PCB Assembly?
Good Assembly Processes
- PCB assembly is continuously defined with reduced cycle time and increased machine features for use. Good products from the manufacturing batch also increase for customers and minimize expenses.
Integration with the Internet of Things (IoT)
- The main feature of rigid-flex boards is their combination of IoT. These important features provide fast and smart connections to devices.
Use of Advanced Materials
- The use of complicity of demands for design and assembly, new materials with good features and electrical parameters are made. Rigid-flex boards are also defined with dynamics in material use and different product features.
Sustainable Solutions.
- PCB assembly companies are focusing on sustainability features. That comes with the use of green materials and reduces greenhouse gas release for processing PCBs. So sustainable and increases PCB assembly methods used for larger production.
