Drone Flight Controller PCBA for UAV Control Systems

Drone Flight Controller PCBA

Custom drone flight controller PCBA for UAV control systems, racing drones, FPV platforms and industrial unmanned aerial vehicles.

The flight controller PCB is designed for dense MCU, IMU, ESC and RF signal routing in a compact board structure. Manufacturing supports multilayer PCB fabrication, SMT assembly, firmware flashing and functional testing.

Multilayer Flight Controller PCB

Flight controller boards require compact layouts and stable signal performance for high-speed control and sensor circuits.

The PCB manufacturing capability supports 2 to 32 layers, with controlled impedance, HDI, blind vias and buried vias available for high-density UAV designs.

High-Tg FR4, halogen-free materials and Rogers hybrid constructions can be selected according to the electrical, thermal and RF requirements of the flight controller.

MCU and IMU Signal Routing

A flight controller integrates the main MCU with inertial measurement units and other sensors used for UAV control.

The PCB layout can be optimized for low-noise routing between the MCU, IMU, ESC interfaces and communication circuits. Controlled impedance can also be applied to high-speed and RF signal paths.

HDI and High-Density PCB

Compact UAV electronics often require a high component density within a limited board area.

HDI technology, blind vias and buried vias can be used to reduce routing space and support multilayer flight controller designs.

The manufacturing capability supports minimum trace and spacing down to 3/3 mil and laser microvias down to 0.1mm.

Flight Controller SMT Assembly

The PCBA supports SMT and DIP assembly for UAV control boards.

Production can handle 0201+ components, BGA, QFN, through-hole and press-fit components. Single-sided and double-sided assembly are available for different flight controller designs.

BGA and QFN Assembly

BGA and QFN packages can be used where high processing capability and compact board dimensions are required.

X-Ray inspection is available for BGA solder joints and other hidden connections, while AOI is used for component placement and soldering inspection.

ESC Interface and Power Control

The flight controller can interface with ESC and power distribution circuits used by multirotor and other UAV platforms.

Power and signal interfaces can be customized according to the motor configuration, ESC architecture and electrical requirements of the drone.

RF and Communication Circuits

Flight controllers may integrate communication interfaces for telemetry, wireless modules and other UAV electronics.

Rogers and Rogers hybrid PCB structures can be used for RF sections where suitable electrical characteristics and controlled impedance are required.

Firmware Flashing and Functional Testing

Firmware flashing is available as part of the PCBA manufacturing process.

ICT, FCT and burn-in testing can be configured to verify the assembled flight controller before shipment.

Functional testing can be based on the customer's test procedure and product requirements.

PCB Materials and Surface Finishes

The flight controller PCB supports FR4, High-Tg FR4, halogen-free and Rogers hybrid materials.

Available surface finishes include HASL, ENIG, OSP and immersion silver or tin.

The material and surface finish can be selected according to the board structure, operating environment and assembly requirements.

OEM and ODM Flight Controller Manufacturing

OEM and ODM services are available for customized UAV flight controller projects.

Customers can provide Gerber files, CAD data or technical requirements. Engineering support can cover PCB fabrication, DFM review, component sourcing, SMT/DIP assembly, firmware flashing and testing.

NDA protection is available for proprietary UAV electronics projects.
