The birth and development of FPC and PCB gave birth to a new product of soft and hard bonded boards. Therefore, the soft and hard bonded board is a flexible circuit board and a rigid circuit board. After the laminating and other processes are performed, the circuit board with the characteristics of the FPC and the characteristics of the PCB is formed in accordance with the relevant process requirements.

FPC Fabrication Production process editing

Because the soft and hard bonded board is a combination of FPC and PCB, the production of soft and hard bonded board should have both FPC production equipment and PCB production equipment. First of all, the electronic engineer draws the circuit and shape of the soft-bonded board according to the requirements, and then sends it to the factory that can produce the soft-hard-bonded board. After the CAM engineers process and plan the relevant documents, the FPC production line is arranged. The FPC and PCB production lines are required to produce PCBs. After the two soft boards and hardboards come out, the FPC and the PCB are pressed together by a press machine according to the planning requirements of the electronic engineers. After a series of details, the final system is adopted. Become a soft and hard board. A very important link should be that the hard and soft board is difficult and there are many details. Before the shipment, it is generally necessary to conduct a full inspection because its value is relatively high, so as to avoid the loss of related interests caused by the supply and demand sides.

Can you provide some examples of electronic devices that commonly use rigid-flex PCBs?

Here are some examples of electronic devices that commonly use rigid-flex PCBs:

Smartphones: Rigid-flex PCBs are widely used in smartphones to accommodate the complex spatial requirements and enable the flexible display connections. They allow for the compact size and thin form factor of modern smartphones.

Tablets and Laptops: Similar to smartphones, tablets and laptops often utilize rigid-flex PCBs to achieve thinner profiles and accommodate the folding or rotating mechanisms in convertible or 2-in-1 devices.

Wearable Devices: Many wearable devices, such as smartwatches, fitness trackers, and medical devices, benefit from the use of rigid-flex PCBs. The flexibility allows the PCBs to conform to the shape of the device while providing reliable connections.

Automotive Electronics: Rigid-flex PCBs are used in various automotive applications, including advanced driver-assistance systems (ADAS), infotainment systems, and instrument clusters. They can withstand vibrations and temperature variations while offering space-saving advantages.

Aerospace and Defense Applications: Rigid-flex PCBs find extensive use in aerospace and defense sectors due to their ability to withstand extreme conditions, perform in tight spaces, and provide reliable interconnections. Examples include avionics systems, satellites, and military equipment.

Medical Devices: Medical devices often utilize rigid-flex PCBs to meet the demanding requirements of compact size, flexibility, and durability. They are used in devices like pacemakers, implantable medical devices, and medical monitoring equipment.

Industrial Equipment: Rigid-flex PCBs are employed in industrial equipment, such as control systems, robotics, and automation devices, where compact size, reliable connections, and resistance to harsh environments are crucial.

Rigid-flex PCB introduction:

A rigid-flex PCB (printed circuit board) is a type of circuit board that combines both rigid and flexible materials in its construction. It offers the advantages of both rigid and flexible PCBs, making it suitable for applications where space constraints, complex geometries, and reliable interconnections are important.

In a rigid-flex PCB, the board consists of multiple layers of rigid materials, typically FR4, and flexible materials, such as polyimide. The rigid portions provide structural support and accommodate components, while the flexible areas allow the board to bend or fold as needed.

Rigid-flex PCBs are commonly used in electronic devices that require a compact form factor, such as smartphones, tablets, wearables, and aerospace applications. They offer several benefits over traditional rigid PCBs, including:

Size reduction: Rigid-flex PCBs can eliminate the need for connectors and cables, enabling a significant reduction in space requirements.

Increased reliability: Rigid-flex PCBs have fewer interconnects and solder joints compared to traditional PCBs, reducing the potential points of failure. They also offer better resistance to vibration and thermal stress.

Improved signal integrity: The combination of rigid and flexible materials allows for optimized signal routing, reducing signal loss, and improving overall signal integrity.

Enhanced design flexibility: Rigid-flex PCBs can be designed to fit complex and irregular shapes, conforming to the available space in a device. This flexibility enables innovative product designs.
