Engineering Prototypes
Validate function, power, wireless, acoustics, structure, and critical use states with hardware, firmware, and sample IDs recorded.
Testing capabilities
Testing Capabilities for Cold-Pressed Cards and FindMy Trackers
Yuli builds project test plans for cold-pressed cards, FindMy trackers, smart badges, and asset labels across electronics, wireless, acoustics, structure, finish, and reliability.
Methods, equipment, sample size, environment, and acceptance criteria are selected for the product configuration. Final limits are recorded in the approved project specification.
Test plans follow the product structure, functions, and use case
| Function and power | Power-up, pairing, advertising states, sleep, ringing, display refresh, buttons, and battery state with hardware, firmware, and environment recorded. |
|---|---|
| BLE / NFC / RF | Antenna matching, read or connection behavior, pre/post press comparison, and device orientation using project-defined methods. |
| Acoustics and controls | Buzzer output and consistency, sound-port influence, button travel, and false-trigger risk. |
| Structure and finish | Length, width, thickness, local protrusions, flatness, windows, edges, surface, and print consistency. |
| Reliability | Select bending, drop, pressure, abrasion, temperature/humidity, ingress, or cleaning resistance by use case; levels and conditions require project confirmation. |
Engineering validation and third-party testing have separate roles
Yuli handles engineering validation and production inspection for prototypes, pilot builds, and outgoing lots. Where ecosystem onboarding, regulatory approval, or a specified standard applies, Yuli prepares controlled samples and technical documents for an approved third-party laboratory.
Pilot and Outgoing Lots
Turn approved methods into production checks, with lot consistency, sampling results, and change-driven retesting recorded.
Third-Party Laboratory
Prepare the controlled test revision, samples, and technical files; the relevant laboratory or platform issues the formal result.
Every test record traces back to a specific sample and revision
Record product, sample ID, hardware and firmware revision, battery, date, environment, method, equipment, raw data, acceptance criteria, and conclusion. Retest scope follows the impact of each change.
