Black Oil ENIG Drone PCB with White Silkscreen and 1.6mm Thickness Customization
Black Oil Drone Circuit Board
,White Silkscreen Colour Drone Circuit Board
A drone circuit board, also known as the flight controller (FC), is the central electronic hub of a drone. Think of it as the drone's brain. This small, sophisticated board contains all the key components that control the drone's flight and functions.
- HDI (High-Density Interconnect) board technology
- Rigid-flex board (used in foldable arm drones)
- High-frequency and high-speed materials (used for high-frequency signal transmission such as 5.8GHz image transmission and radar waves)

FThe immersion gold plating has a level 1 adhesion rating. After repeatedly bending the circuit at the robotic arm joint, there was no exposed copper on the solder pads. The black solder mask exhibited strong resistance to bending. After a drone drop test (1.5m), the circuits remained intact, and the drone was still able to fly normally.

CUpon receiving the order, I noticed that two of the circuit boards had slight exposed copper at the edges of the solder mask. After contacting customer service, they quickly sent replacements. Their after-sales service is commendable.
