BENCHTOP TESTER FOR MOBILE DEVICE MAIN PCA
Product Requirement
- Test mobile device Main PCA for circuit parameters, LED driver functionality, audio circuit performance, UART and I2C communication, and firmware download.
Test Parameters
- Measure audio frequency and power performance (onboard microphone and speaker amplifier), test circuit for shorts, opens, measure voltage and current, download bootloader and bootcode to processor, initiate self test and communication tests.
Hardware
- Utilized PCA test fixture with pogo pin connections to test points along with a SMA pogo connector. Embedded speaker for audio test of microphone.
Tool Operation
- Computer software written to communicate for electrical test equipment (digital volt meters, power supplies, and in-circuit programmer). Operators inserted the PCA into a fixture, closed lid, and initiated test sequence on computer. Results were listed on the screen with green or red checkmarks next to test items. Data was saved to log file for evaluation.
