PCB Design and Assembly

Printed circuit boards (PCBs) are a fundamental component of any unmanned system, enabling communication between sensors, power systems, and onboard computing units. Unmanned aerial, ground, surface, and underwater vehicles rely on multiple PCBs working together to support flight control, power management, navigation, and data processing.

PCB Prototyping by San Francisco Circuits (SFC)

Electronics manufacturing companies specializing in PCB design and assembly provide services such as custom PCB fabrication, multilayer PCB production, and high-reliability PCB assembly, ensuring that these critical systems function seamlessly.

State-of-the-art PCB manufacturing and assembly processes include:

• Surface mount technology (SMT) assembly – Enabling compact, lightweight, and high-density circuit board designs ideal for UAVs and autonomous robotics.
• Through-hole assembly (THT) – Ensuring robust mechanical connections, suitable for high-vibration environments.
• PCB prototyping – Providing prototype PCB assembly for functional verification before mass production.
• PCB testing and inspection – Ensuring performance and quality through PCB rework, burn-in testing, and reliability testing.

From mission-critical UAV avionics to AI-driven robotics and autonomous marine vessels, advanced PCB design and assembly processes are essential for ensuring reliability, efficiency, and seamless integration across complex electronic systems.

Contract Manufacturing

Many companies in the electronics manufacturing industry provide contract manufacturing services to OEMs (original equipment manufacturers) in the unmanned systems sector. Contract electronics manufacturing companies handle the complete production process, from BOM (bill of materials) management to final product assembly, allowing UAV and unmanned vehicle manufacturers to focus on innovation and system integration.

Key contract manufacturing services include:

• Turnkey manufacturing – Handling every stage of production, from sourcing components to final assembly and testing.
• BOM management and component sourcing – Ensuring availability of high-quality, RoHS-compliant components while mitigating supply chain disruptions.
• Custom cable assemblies and wire harness manufacturing – Providing tailored wiring solutions for UAV flight control systems, ground vehicles, and robotic applications.
• Just-in-time (JIT) manufacturing – Reducing inventory costs while maintaining rapid production capabilities for critical drone and robotics components.

By outsourcing production to electronics manufacturing services companies, OEMs can maintain cost efficiency while benefiting from cutting-edge manufacturing expertise.

Testing and Quality Assurance

The reliability of drone and unmanned systems electronics is crucial in extreme environments. Electronics manufacturers incorporate rigorous testing and quality assurance procedures to verify product performance, safety, and compliance with industry standards.

Advanced functional testing ensures that UAV electronics, flight controllers, and mission-critical communication systems meet stringent reliability requirements. This includes:

• Environmental testing – Evaluating resilience to temperature fluctuations, humidity, and mechanical stress.
• EMI shielding and electromagnetic compatibility (EMC) testing – Protecting sensitive electronics from external interference.
• Burn-in testing – Detecting early failures in power modules and critical avionics components.
• ESD protection measures – Ensuring electronic components are safeguarded from electrostatic discharge damage during assembly and operation.

Testing methodologies such as design for assembly (DFA) and reliability testing further enhance product lifecycle performance, ensuring that UAVs and autonomous systems function optimally in real-world conditions.

Electromechanical Assembly

In addition to circuit board fabrication, electronics manufacturing services providers offer electromechanical assembly solutions to support UAV and unmanned system integration. This includes:

• Custom enclosures – Ruggedized housings designed to withstand harsh operational conditions.
• Electromechanical component integration – Combining PCBs, actuators, sensors, and power management units.
• Wiring solutions and harness assembly – Custom cable and wire harness manufacturing for drones, autonomous robots, and vehicle control systems.
• Conformal coating – Applying protective coatings to circuit boards to prevent moisture, dust, and chemical damage.

By leveraging contract electronic manufacturing, OEMs can access complete electronics assembly services, from small-batch prototyping to full-scale production.

Regulatory Compliance

Electronics used in UAVs and unmanned systems must adhere to industry-specific compliance standards to ensure safety, longevity, and interoperability. Electronics manufacturing solutions providers incorporate:

• RoHS compliance – Restricting hazardous substances in electronics manufacturing.
• ISO and IPC standards – Adhering to global quality control guidelines for PCB production, electronic assembly manufacturing, and circuit board prototyping.
• Obsolescence management – Helping companies address component end-of-life (EOL) challenges and sourcing alternatives.

By integrating regulatory compliance into every stage of manufacturing, electronics manufacturing companies help unmanned system developers achieve consistent, high-quality production while meeting safety and environmental regulations.

3D Printing in Electronics Manufacturing

Many electronics manufacturing companies now offer 3D printing services to support rapid prototyping and custom enclosures for drone and unmanned systems. Additive manufacturing technologies allow for faster design iterations, lightweight structures, and enhanced thermal management solutions. Whether used for prototype circuit board assembly, housing for electronic components, or structural drone parts, 3D printing is revolutionizing the way electronics are developed and integrated.

Meeting Industry Challenges with Innovation

The unmanned systems sector demands precision, efficiency, and reliability in every component. Just-in-time (JIT) manufacturing, obsolescence management, and original equipment manufacturing (OEM) solutions are critical for reducing lead times and ensuring supply chain efficiency.
