Advanced Electric Trimmer FCT Test Solutions
A production-line functional test bench built to validate trimmer PCBs before dispatch—covering power paths, protection logic, charging behavior, and motor drive response. The workflow supports both the semi-finished stage (board without battery) and the finished stage (board with battery), using controlled supply inputs, battery simulation, and precise voltage/current acquisition for dependable pass/fail decisions.
Test system highlights
Repeatable + shop-floor friendly- Runs FCT at both semi-finished and finished assembly stages
- Battery dummy supports sink/source current for realistic conditions
- Low-current standby measurement for leakage and sleep-mode validation
- Protection checks for under-voltage / over-voltage events and safe recovery
- Motor-control verification using dummy load and voltage-state checks
- Automated logging + report output for traceability and QA review
Specifications
A clear test-coverage matrix for trimmer PCB validation. Final limits, fixtures, and throughput are tuned to your SKU, connectors, and production process.
