A Flexible PCB, alsoknown as a Flex PCB or FPC, is a lightweight printed circuit board made fromflexible materials such as polyimide.
Unlike a rigid PCB, itcan bend and fit into compact or irregular spaces. Flexible PCBs help reducewiring, save installation space and provide reliable electrical connectionsbetween moving or closely positioned robot components.
Flexible PCBs provideelectrical connections for power and signal transmission while allowing thecircuit to bend or move within the product.
Depending on thedesign, they can support:
Sensor signal transmission
Camera and display connections
Motor and joint-control signals
Power and data connections
Compact electronic module integration
Connections between moving robot parts
Antfield flexible PCBscan be used in:
Humanoid robot joints
Robotic arms and grippers
Camera and vision modules
Sensor and encoder modules
Displays and control panels
Battery and power connections
Wearable and service robots
Industrial robots, robot dogs and compact robotic devices
Flexible PCBs can becustomized according to the customer’s design and application requirements,including:
Single-sided, double-sided and multilayer FPCs
Polyimide base materials
Different copper thicknesses
ENIG and other surface finishes
Stiffeners for connector and component areas
Controlled impedance when required
SMT component assembly
Prototype and volume production
To improve FPCreliability, the design should consider:
Minimum bending radius
Static or dynamic bending requirements
Copper thickness and trace direction
Stiffener location
Connector and contact-finger design
Component placement in non-bending areas
Mechanical stress and installation space
Operating temperature and environment
Components shouldgenerally be placed away from repeated bending areas to reduce stress on solderjoints and copper traces.
Antfield reviews theFPC design and manufacturing requirements before production. Quality controlscan include:
DFM and engineering file review
Material and copper-thickness verification
Dimension and outline inspection
Coverlay and stiffener alignment checks
Electrical continuity and isolation testing
Surface-finish and contact-finger inspection
SMT assembly inspection when required
Bending and functional testing upon agreement
Final appearance and packaging inspection
Production records and traceability
