Flexboard assemblies are used in a variety of applications, particularly where space is at a premium or where components need to conform to a specific shape. Common applications include:

• Wearables: Smartwatches, fitness trackers, medical devices
• Consumer Electronics: Smartphones, laptops, and tablets (e.g., internal flexible cables or connectors)
• Automotive: In dashboards, control systems, or even flexible sensors
• Medical Devices: Flexible sensors or diagnostic equipment
• Aerospace and Defense: Flexible interconnects in sensors or systems subject to movement or vibration

Layering

• Single-layer Flex PCB: This is a simple design where only one layer of copper is used for the circuitry.
• Multi-layer Flex PCB: For more complex designs, multiple layers of flexible material are stacked and bonded together with adhesive and copper interconnects between layers. This allows for higher component density and more complex circuits.

Assembly Once the flex PCB is fabricated, the assembly process is similar to that of rigid PCB assembly:

• Soldering Components: Surface mount technology (SMT) is the most common method for placing components on a flexible PCB. Because the board is flexible, it requires careful handling to avoid damaging the traces or components.
• Bending and Testing: If the flex PCB needs to bend, it is tested to ensure that the components stay in place and that the electrical connections remain intact after bending. This might involve some custom handling equipment or fixtures to position the flex PCB correctly during soldering.
• Inspection and Quality Control: The finished flex PCB assembly undergoes rigorous testing, including electrical testing (to check for shorts, open circuits, etc.) and mechanical testing (to ensure it can withstand bending or flexing).
