Overview
Electronics test automation is a fixture, software, and data problem.
China has strong suppliers for PCBA test fixtures, programming stations, camera inspection, burn-in handling, and automated line-side test equipment. The risk is that test automation can look mechanical while the real challenge sits in instrumentation, firmware access, data logging, and false-pass controls.
Systems sourced from China
PCBA functional test
Bed-of-nails, connectors, fixtures, load boards, barcode flow, HMI, and test sequence control.
Programming and flashing
Multi-up programming, fixture design, device handling, serialization, traceability, and rework logic.
Burn-in and aging
Racks, temperature control, power cycling, data capture, alarm logic, and batch traceability.
Automated inspection
Camera inspection, OCR, label checks, LED checks, connector presence, and reject handling.
RFQ details suppliers need
- Board drawings, test points, firmware access, instruments, and pass/fail logic.
- Cycle time, fixture count, operator workflow, DUT handling, and rework process.
- Data export, traceability, MES connection, barcode flow, and reporting needs.
- Safety, ESD, enclosure, documentation, spare fixtures, and calibration requirements.
How to validate suppliers
Ask for comparable test fixtures, software screenshots, test report samples, control cabinet examples, instrument lists, calibration method, and FAT plans using real boards. The supplier should explain the test architecture, not only the fixture hardware.
