Challenges in Drone Integrated Circuit Application

1. Core Chip Shortages

High-end drone chips-such as flight control processors, AI computing chips, high-precision sensors, and RF communication chips-still have relatively low localization rates and a high dependence on foreign suppliers. Combined with geopolitical restrictions and tight production capacity from original manufacturers, this results in long lead times, limited availability of spot stock, and significant price fluctuations. As a result, drone production is often delayed due to chip shortages, highlighting the vulnerability of the supply chain.

2. Trade-off Between Computing Power and Power Consumption

Industrial and commercial drones increasingly require high computing performance for AI-based obstacle avoidance, object recognition, and 3D reconstruction. However, drones are constrained by compact size and limited battery capacity. High-performance chips often lead to excessive power consumption, heat dissipation challenges, and reduced flight endurance.

3. Limitations in Endurance and Payload Capacity

Due to bottlenecks in lithium battery energy density, mainstream drones typically achieve only 20–30 minutes of flight time, while heavy-lift models suffer even shorter endurance and higher costs. On the chip side, insufficient low-power design and sub-optimal power management efficiency further limit improvements in flight time, severely restricting large-scale commercialization in logistics, long-range inspection, and similar applications.

4. Reliable Procurement Channels

With strong demand in the UAV industry and ongoing supply chain and capacity constraints, chip shortages remain a significant challenge. Choosing a stable and reliable procurement channel is essential to ensure smooth production and R&D progress.
