Uncover the selection of drone PCB board! How to make wise decisions?

/in /by

Drones have become a hot topic in modern technology, and more and more people are starting to purchase drones for entertainment, aerial photography, agriculture, security and other fields. However, as one of the core components of drones, the Printed Circuit Board plays a crucial role in determining drone performance and stability. This article will provide a detailed explanation of the selection of drone PCB boards from four aspects, helping readers make wise decisions.

1. Material selection of PCB board

The material selection of PCB boards directly affects the performance and durability of drones. Common PCB board materials include FR-4, metal substrates, ceramic substrates, etc. FR-4 is the most commonly used substrate material with good insulation and heat resistance, suitable for most drone applications. The metal substrate has better heat dissipation ability and is suitable for high-power applications. Ceramic substrates, on the other hand, have excellent insulation and high-frequency performance, making them suitable for applications with high frequency requirements. Choosing suitable PCB board materials for application scenarios can improve the performance and stability of drones.

2. The number of layers and layout of PCB boards

The number of layers and layout of drone PCB boards are also important factors determining their performance. Smaller drones typically use double-layer or four layer PCB boards, while larger or more complex drones require more layers. A reasonable layout can reduce electromagnetic interference and signal crosstalk, and improve the stability and reliability of unmanned aerial vehicle systems. When selecting a PCB board, the appropriate number of layers and layout should be selected based on the needs of the drone and the layout of other electronic components.

3. Quality control of PCB boards

Ensuring the quality of PCB boards is crucial for the performance and reliability of drones. The first step is to choose a reputable PCB board manufacturer and understand their production process and quality control measures. We also conduct professional quality testing, including electrical testing, pad inspection, and circuit tracking. Some high-quality PCB boards also require environmental and reliability testing to ensure they are suitable for working in various complex environments. Only by ensuring the quality of the PCB board is the stability and reliability of the drone system guaranteed.

4. Size and weight of PCB board

For drones, size and weight are also crucial parameters. Excessive size and weight can affect the hovering time and flight stability of drones. Therefore, when selecting a PCB board, the appropriate size and weight should be selected based on the needs of the drone. At the same time, it is also necessary to consider the compactness and durability of the PCB board to ensure the performance and service life of the drone.
