Reliable PCBA manufacturing requires more than assembly. XWONDER supports AOI, X-ray, ICT, FCT, firmware programming, calibration, and optional burn-in testing to reduce quality risks before shipment. From prototype debugging to volume production inspection, our testing capability verifies soldering quality, component accuracy, circuit integrity, functional performance, and production consistency.
PCBA defects may come from soldering issues, wrong components, missing parts, polarity errors, hidden BGA solder defects, firmware problems, or functional failures. XWONDER integrates inspection and testing into the manufacturing process to detect issues early, reducing rework and improving production reliability.
| Test / Inspection | What It Helps Verify |
|---|---|
| 3D AOI | Solder defects, tombstoning, bridging, insufficient solder, polarity errors |
| X-Ray Inspection | Hidden solder joints, BGA/QFN voids, internal solder defects |
| ICT | Shorts, opens, resistor/capacitor/inductor values, circuit integrity |
| FCT | Complete functional performance under simulated working conditions |
| Programming & Calibration | Firmware writing, serial number writing, calibration parameters |
| Burn-In Test | Optional temperature or voltage stress screening |
ICT identifies basic electrical problems such as shorts, opens, and incorrect component values. FCT verifies whether the PCBA works under simulated operating conditions, including communication interfaces like CAN, I2C, USB, Ethernet, UART, or other customer-defined functions. XWONDER can review test points, prepare test strategy, and coordinate programming and functional validation during prototype, NPI, and volume production.
During prototype and NPI, testing ensures early detection of hidden risks in communication timing, thermal performance, test coverage, firmware behavior, and production repeatability. Our team documents test results, identifies recurring issues, and provides feedback for schematic, PCB layout, BOM, fixture, and test process improvements.
For volume production, XWONDER supports batch testing, programming, calibration, final inspection, outgoing quality control, and production data records according to project requirements, ensuring repeatable and traceable testing.
XWONDER can help define and execute the right testing process for prototypes, small-batch, or volume production PCBA projects.
