Micro GaN Servo PCBA

Ultra-compact low-voltage GaN servo control boards built for embedded robotic joints, grippers, UAV actuators, and precision mechatronic modules.

Target Buyer:Best for robotics startups, R&D teams, and OEMs that need a custom GaN servo board instead of a catalog industrial drive.
Compact GaN servo PCBA for robotics OEM manufacturing

Capability Highlights

  • GaN power stage layouts for compact 24 V, 36 V, and 48 V servo platforms
  • SMT assembly, AOI inspection, microscope solder review, and functional test support
  • Prototype-to-volume manufacturing path for hardware teams that do not want to build an internal PCBA line

Typical Applications

  • Humanoid robot fingers and compact joints
  • Dexterous grippers and end effectors
  • Drone gimbal, UAV actuation, and lightweight servo modules

Engineering Focus

  • Thermal layout around GaN FETs, gate drivers, current shunts, and copper pours
  • Control-loop bandwidth, encoder interface, and firmware handoff requirements
  • DFM/DFT review for micro connectors, stack height, coating, and batch test fixtures

Key Evaluation Matrix

MetricTypical RangeWhy It Matters
DC bus voltage24 V / 36 V / 48 V / 60 V classMatches battery-powered robots and avoids oversized 220 V industrial servo drives.
Board thickness and stack heightApplication-specific compact stackJoint modules, hands, and medical tools usually fail on mechanical envelope before electrical performance.
Inspection coverageAOI, microscope review, functional test, thermal samplingMicro GaN boards have dense pads and high switching stress; inspection discipline reduces early failures.

RFQ Checklist

  1. Motor voltage, peak/continuous current, and bus voltage range
  2. Board envelope, stack height, connector constraints, and 3D STEP envelope
  3. Encoder type, communication bus, firmware ownership, and test acceptance method
  4. Prototype quantity, pilot quantity, target annual volume, and launch schedule

Risk Controls

  • GaN layout overheats in a sealed joint: Review copper area, heat path, switching frequency, enclosure contact, and thermal image data before pilot release.
  • Prototype works but cannot scale: Lock BOM alternates, fixture strategy, panelization, and electrical test points before volume quoting.

Buyer FAQ

Can you manufacture from our existing PCB files?

Yes. We can review Gerber, BOM, placement, test requirements, and mechanical constraints, then quote prototype and pilot builds.

Can you help redesign a catalog servo board into a smaller custom board?

Yes. We can support DFM, stack-height reduction, connector changes, thermal path review, and production test planning.
