What is a Flex PCB?
- Flexible base dielectric material such as polyimide forming the core.
- Copper foil conductors patterned on the top, bottom and two inner layers of the core.
- Cover layers laminated above and below for insulation, abrasion resistance and stiffness.
- Plated through holes (PTH) and buried vias for vertical interconnections.
Edge contacts or stiffeners to provide external connections.
This construction provides the highest routing density on a flex PCB with fine conductors and clearances.
Applications of 4 Layer FPC
- Wearable devices – Smart watches, fitness trackers, AR/VR headsets.
- Flexible displays – Edge or foldable displays, large LED video walls.
- Automotive – In-car displays, lane departure systems, LiDAR.
- Aerospace/Military – Helmet systems, communications, guidance systems.
- Medical – Ultrasound transducers, implants, endoscopes.
- Industrial – Flexible HMIs, robotic interconnects, motion control.
- Consumer Electronics – Foldable phones, cameras, portable electronics.
Benefits of Flexible Circuits
- Maximum routing density – Complex, compact layouts with traces on 4 layers.
- Embedded discrete passives – Buried resistor, capacitor and inductor integration.
- Controlled impedances – Tight impedance control for matched high speed signals.
- Integrated shielding – Entire layers can provide EMI/RFI isolation.
Higher component density – More components in a given area with multilayer escape routing. - Multilayer stacking – Can integrate other flex or rigid-flex layers.
Greater functionality – High density interconnects enable more capabilities and features. - Miniaturization – Ideal for complex circuits in small, lightweight products.
- Lower assembly costs – Eliminates separate flexible cabling and connectors.
- High frequency performance – Controlled impedances benefit RF applications.
