What We Do — and What We Don’t

We are a customer-design-driven PCBA house. You send us the Gerber and BOM; we handle everything from sourcing to finished board.

✓ PCB Fabrication1–20 layers, FR-4, HDI, aluminum, flex & rigid-flex
✓ Component SourcingFull turnkey BOM procurement with alternative sourcing
✓ SMT + Through-Hole Assembly0201 to BGA, fine-pitch, mixed technology
✓ Testing & Box-BuildAOI, X-ray, ICT, FCT, and full system integration
✗ Schematic Design from ScratchWe execute your design — not replace your EE team
✗ Mass Consumer VolumeOur strength is prototype to medium-volume precision
Industry Focus

Three Verticals. Deep Domain Knowledge.

We don’t chase every market. We specialize in three demanding sectors where quality, traceability, and reliability are non-negotiable.

🤖

Robotics

Motion control boards, sensor fusion modules, servo drivers, and AGV/AMR mainboards that demand EMC robustness and long MTBF.

  • Servo & stepper driver assemblies
  • LiDAR / vision sensor interface boards
  • Industrial communication (EtherCAT, CAN, Modbus)
  • Burn-in testing for motion-critical boards
⚕️

Medical Devices

Assembly aligned with medical-grade quality expectations — full traceability, controlled ESD environments, and IPC-A-610 Class 3 workmanship available on request.

  • Patient monitoring & diagnostic boards
  • Imaging equipment control modules
  • Wearable & portable medical electronics
  • Component-level traceability (lot & date code)
🔬

Instrumentation

High-precision signal-chain boards for test & measurement, lab automation, and industrial analyzers — where low-noise assembly and calibration matter.

  • Data acquisition (DAQ) and ADC/DAC boards
  • Laboratory & process analyzers
  • Environmental / sensor monitoring systems
  • Low-noise RF & analog front-end assembly
Why Customers Choose Us

Four Reasons SMEs and R&D Teams Trust Tengda

01Flexible on Low & Mid Volume

From 1 prototype to 10,000 units — no hidden MOQ, no volume discrimination.

02Engineer-to-Engineer Support

Your inquiry lands on an engineer’s desk, not a sales queue. Technical answers, not scripted replies.

03DFM Review Before Production

We catch footprint, polarity, and panelization issues before they become rework costs.

04Component Alternative Sourcing

Facing EOL or shortage parts? We help you find qualified cross-references to keep the build alive.
